5900x edc limit reddit. 45 GHz and nearly 90°C.


  • 5900x edc limit reddit I also kept a spreadsheet to track I have a 5900X with a Thermalright FS140 which is similar in performance as Noctua D15. The additional physical cache just does wonders for games which are limited by it - if there was a lower core count cpu with incredibly high cache, I would have easily jumped on that instead. PBO limit is set to +50MHz, Curves to -30 for all cores, full details in linked album above. C23 score 22093 EDC: 300A. R20 around 72C. Now, at 204 128 192, my CBR23 scores are highest I've seen for multi-thread: 23342, and 1644 single (highest on air was 1673). Here are some Cinebench R20 multi-threaded benchmarks to illustrate the silly behaviour. I haven't actually tested the EDC bug on my 5900x but it was just crossing my mind this weekend. _BoneZ_ 5900x Share your power limits 5900x. 1GHz, and decent multi-thread at 4. On my particular 5900x I ran into problems with EDC at like 140 or below. Slowly scale down tdc until you get a peak load power that gives you reasonable temps. These correspond to "motherboard limits" This has been how the system has been running happily for about a month Get the Reddit app Scan this QR code to download the app now. EDC 120 in Ryzen master hit 4625Mhz when limit was default 90c. As of finding EDC/TDCbasically I set limits to MB and found the max EDC/TDC, set those manual and now I'm working my way down by 10A increments while running tests per down bump. After you find your PBO limits, I'd think about whether you want to prioritize single core or all core For PBO would you suggest +50/100? the default limits are the same but I'd recommend higher values with a 5950x. I should have mentioned that the prior OC was using Curve Optimiser. In addition, the power limit is 1000 watts, and the to EDC limits are 160 and 200. For the record, my own PBO2/CO settings are fairly close to as good as my sample of the 5900x will do, and those PPT/TDC/EDC are what I arrived at, with scalar 1x and Boost at +150Mhz. I know So I changed the VRM power phase to extreme and now I hit the edc limit which and the scores arrived at what they are now. That EDC looks awfully low. . You can just put the EDC, PPT etc to motherboard, because it is the cpu that asks for the amount of power it wants, not the socket force feeding it. My Ryzen9 5900X PPT 195 EDC 150 TDC 130 CL14 3600MHZ 4X8GB Overclocked cl14 3733mhz stable at 1. 180A EDC is set and the CPU does exactly that while hitting something like 70C. You'll be fine with the d15. 0. I'll give your suggested tdc a shot. 140A is default EDC and increasing this by using board limits does not allow PBO to move core voltages above ~1. That TDC could probably go up to 135 or so but I doubt it would impact stability - just sustained boost clocks. Basically like Intel extreme tuning I've used on my Thinkpads to undervolt. OK, still working on PBO2 settings for a 5900x on a MSI Tomahawk 570x. This is bizarre. I used to just whack PBO on "enabled" in the bios, which resulted in PPT 500, TDC 210, EDC 280. I didn't really notice a difference between this and auto. 35-4. Still doesn't answer why EDC 120 on Ryzen master / PBO limit = motherboard gives entirely different results than defining in BIOS. If you set limits to motherboard, does it set 168A? Ryzen Master also shows "Max 168A?" Otherwise if manual settings somehow cap out at lower than the motherboard limit, it would be a bios bug. Ryzen 9 5900x/pbo manual limits. And as for other games, the 5900x does the job good enough. It's at 150 right now, and has been for most of the last year. My board is a measly B550M Tuf gaming, and it sets EDC to 180A. I've running tests on EDC first, I guess will set it at the best mix of ghz/points/temp and will move to TDC after. Put scalar on auto. Many Asus/MSI/ASRock users that do have 1. Quickly wrapped my head around PBO2 and PPT/EDC/TDC thanks to this community ️ and started doing some testing. Yeah curve optimizer is a long process, can take a week of regular usage and then you crash randomly, usually it's the second ccd that takes largest offset on 5900x so it's likely true. Still trying to figure out a stable 4. Thanks for the Info though! I just rechecked Der8auer video on 5900X OC from when it came out and he just sets the 3 values and the CPU goes as high as it can within these limits. I'd recommend either lowering the PBO limits to stock for a 5900x or not running that stressful of a test if everything is stable. If you watch real time what ppt, edc and tdc and temps are doing, especially if any of them are hitting the limit, it will give you a good idea what is holding it back. First, manual setting I used was these within Precision Boost Overdrive: All Cores to -25 PPT Limit: 165 TDC Limit: 115 EDC Limit: 150 Adjusting ppt, edc, tdc limits for Ryzen 9 . Or I’m running a 5900x on a strix x570-e and have questions about voltage. It just sits at 90c flat, TDC limit is always 95A. Manual oc disable pbo automatically. So I set it to 120 and 75 respectively, and raised the thermal throttling to 67 degrees. I used two of the settings; the one I manually set up and the one I used Ryzen Master's Curve Optimizer. I've got to work right now so I don't have the chance to test it yet, but I might see the same temps if I unlock the PPT and EDC limits because it will throttle on TDP 75A first. i also noticed that the standard PPT, TDC and EDC limits are much lower in the standard settings. I don't understand why Ryzen master is showing you 0 for EDC I use hwinfo64 to get an idea what is going on. Your power limit is killing you put that shit to no limit and just watch thermals same with EDC limit put it to no limit. 45 GHz and nearly 90°C. Scores and performance will depend on actual EDC usage by software, i/e R23, CPUz etc perform well with low EDC, while more demanding XMRIG needs higher EDC. msi mag x570 tomahawk/ 5800x EDC question . values, my 5900X will happily draw ~200W+ at ~85°C (I've only managed to get it to go over 90°C once at stock, and despite what people say, that didn't force thermal throttling at all). PPT 185 will limit you slightly if you're going for balls-out EDC Limit 100 (This is the one that fine tunes your curve optimizer after you find the best curve optimizer numbers. so i switched back to standard mode to limit the power draw of the chip to 105w like advertised and the temps are pretty fine right now, like 77C under full load and 70C gaming only. Or For indication on my rayzen 9 5900x Base temp : 88 °C After : 76 °C -13. 775 all core to get 24000 in CB R23. CPU temp 75. Reply reply luffy435 You have a lot of headway still. 2. 525 GHz during an x265 encode, and at ~80°C - that's seriously impressive compared to using Curve Optimiser which saw an all-core sustained boost of ~4. I've got a Ryzen 5 5600x on a B350 PC Mate with Boost override set to +200Mhz and Curve optimizer set The maximum limit for EDC allowed should be programmed by the vendor based on the limits of the VRM. From here I'd adjust PPT next, leaving EDC as high as possible due to its impacts on "single threaded, bursty" performance Reply reply -bosmang- Zen 3 frequenzy / temperature scaling - 5900X My best scores were with 170/130 for tdc/edc but I hit the limit of my cooler before anything else. I noted down the parameters, went to the BIOS, set Boost to 150MHz and Curve Optimizer to -20 After that I set the PPT to 200 and kept bumping the TDC and EDC up by 10 until I reached my target 80c max on CB20. It went on to being almost godlike in single-thread over 5. After rebooting, launch HWinfo64 and scroll down to the section indicating the PPT, I browsed through many threads but none seems to state clearly what the safe values for these limits are and if there even are any. EDC - electrical design current, lowering EDC benefits by lowering temperatures, while at the same time allowing CPU to boost higher. My Cinebench R20 scores are typically 8800-8900, I haven't run R23. You need to make small changes to your Curve Optimizer settings, and the power limits like PPT and EDC, and then you need to test extensively after each change. Encoding x265 using 'near-stock' (enabling one Asus option) keeps all cores at 4. PBO: Advanced PBO Limits: Manual PPT / TDC / EDC limit: 225, 150, 190 PBO Scalar: Manual 1X Max CPU Boost Clock Overdrive: 100 Mhz Platform thermal throttle limit: Auto Curve Optimizer: By Core. I think this is because of bad experiences overclocking FX 8350 and 6700K, I had unbelievable stability issues on those chips. Where do I find these default limits in ryzen master for my 5900x? PBO Limits: [Motherboard] (PPT= 720 W, TDC= 360 A, EDC= 215 A) The CPU will only reach the EDC limit with these settings, this is the default for my board. To determine the base performance from which to make your adjustments, simply enable PBO2 then set power limits to 'motherboard' and scalar to '1x'. I've been getting some better scores while slowly adjusting PPT - higher is going to give you better performance always, with diminishing returns (as this is your power limit) EDC/TDC - have more of a sweet spot as opposed to “higher is always better”, because if you just set these to 200 each then your CPU will just use the highest voltage allowed by FIT to boost (thus chewing up more PPT), when it I did the same test as always, and it showed me that watts peaked at 120W, and the TDC peaked at 71A, they couldn't go any higher because I had the EDC limited. Setting manually 130A limit for CPU EDC noticeably improved my performance. I got the best performance with 130/170 on TDC/EDC for Cinebench. Help needed for undervolting 5900x - PBO he states that alternatively, you can assign manual PBO limits for PPT, EDC, and TDC. (Your suggested edc lined up with my motherboard limit. View attachment 2527033. At some point, you will find they might go up then go down again. My temps are in the 70s under all core workload without PBO, high 80s to low 90s with PBO limit set to motherboard(MSI X570 TOMAHAWK), and 60s while gaming. So adjusting the TDC down probably won't help if it isn't peaking there. I set the PPT and TDC limits to the default for a 105W CPU so they'd never be the limiting factor for performance. EDC will almost always hit 100% and TDC will be close to 100% under certain load. The AMD default for the 5900X seems to be : PPT Power limits are just limits. For me, the optimal 5900x numbers on noctua d15 are 220ppt, 165 TDC (doesn't seem to matter much), and 135A EDC. A report the fix. [90] Calibrated Temperature Threshold to switch back [80] PBO Limits [Manual] PPT Limit [W] [200] TDC Limit [A] [140] EDC Limit [A] [160] Precision Boost Overdrive Scalar [Manual] Precision Boost Overdrive Scalar [1X] Curve As intended, the 5900x has those super fast jolts where it shoots up to 70, down to 35, up to 76, down again but Get an AIO heck with a CoolerMaster 212 Black Edition with just enabling PBO and TDC,EDC and PPT in cinebench Also you can set temp limit in mobo setting under pbo settings. I wanted to lap it, but I ended up selling it due to money problems. Curve Optimizer: -15 offset all cores. c have this limited EDC bug when its manually set. Latest bios, cooler is a NH-D15. The L3 cache AIDA64 results was a BIOS bug that was fixed with For pbo don't use boost override or llc. Best bet on this is to set If your main goal is to reduce the temperature of your CPU, stop messing about with PPT, EDC, TDC and anything else, and simply set "Platform Thermal Throttle Limit" to Manual and set whatever temperature you want to limit it to. 46 gHz. Jump to Latest You still need to increase the core clocks to take advantage of the higher power limits. I use PPT 200W, TDC 140A, EDC 160A. 8 degree. I have pbo on with my 5900x, set to mobo limits (dark hero) and only 1 fan on my d15 and during gaming it peaks at 60. I had put my power limit at 600 watts with the EDC limits to 500. the EDC ceiling limit was introduced related to the 5800x3d, This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent API changes, Get the Reddit app Scan this QR code to download the app now. EDC limit hit. Or you can put them lower to reduce the heat (and a little performance). EDC limit of 128 seems low. Your CPU may or may not handle the same settings. Okay well I will go over the 3 parameters and let you tweak them (that’s half the fun anyway) EDC is electric design current, this is the amperage limit for very short term transient current demand, a good way of looking at EDC is it allows a single core or multiple cores to boost to maximum for a single second or so where temps won’t get out of hand so I wouldn’t worry Your edc and tdc will determine the resulting ppt so start tuning edc for boost and then tdc for temps. 6GHz+ all core during Cinebench R23 but it's fairly close. C23 score 21169 EDC: 999A. And that you can set default limits found in Ryzen Master. I was running into this problem with my Ryzen 2700X but it would just downclock itself instead of BSOD. The "High Temperature Integer Threshold" is reset at 70c for AMD processor family 19h, the same as family 17h. Looking for Guide Can you show your optimal values combination for PPT TDC AND EDC for high clock with lowest temps, i guess that s the point of it. Maybe start with PPT first if temps are more important/limiting. iirc I have 155/135/120 PPT,EDC,TDC using a Cryorig air cooler. Several mental breakdown from inconsistent crashes and restart that I don't want to RMA my 5900x. 4ghz in Cinebench R23 with 22223 points in Multicores I start off with. Yup, this is the way. Newer bioses with AGESA past 1. I would start with setting PPT to the max of what the 5900x can handle and adjusting EDC and TDC afterwards. How much would I need to increase my EDC and TDC limits if I were to push my PPT to let's say 165W? Is there a For my 5900x, my final limits were 200/120/145. I set the scale factor to manual and set it to 10x. Actually limiting EDC to 165 instead of 190, 210, or higher that a lot of people set without testing is still safer than setting to motherboard limits (which is 190 for my board). 3. Pay attention to hwinfo effective core clocks. When tweaking PBO, a lot of people set that to 255; does that value represent degrees in Celsius and is the default 90? I have a 5900x and I keep PBO disabled since the stock performance is more than fine for my workloads, but was curious to see what PBO potential it has, and with PBO set to advanced and PPT/TDC/EDC set to Motherboard (500/200/280), in Cinebench R20 i get 23 votes, 78 comments. Yes good point, based on what you found then, I could have probably set my TDC at 75W and got the same results because it will hit that limit before PPT and EDC. Black with the 7mm offset brackets with Arctic MX-6 thermal You really need to look at what is happening whilst R23 is running. Running with a limit of 65C will seriously limit performance, what's the point of getting a 5900x then? 85C limit is a lot more reasonable and you'll lose only less than 5% performance, but anyway if you're not reaching 90C continuously there's nothing to worry about. Passes Corecycler with 10 mins stress test on each core and no WHEA errors during low load and gaming scenarios. I think it's fine at its full limit, especially because out of the box my 5950X hits the EDC limit near instantly. I figured out whats going on. 07 Get the Reddit app Scan this Personally, I do PBO with Curve Optimizer but I also limit the CPU EDC to 90A (instead of the default 140A), I have 5900x with PBO on (default limits) in P500A with Arctic 360 and I get 77-81*C max in R23 depend on ambient temperatures. Get the Reddit app Scan this QR code to download the app now. Btw I was running a MSI board as well a X470. starting with PPT Sure, CPU won't damage itself, but for 5600x those limits are to much. Limits Ryzen Master usefulness if values don't translate the same. But that limits. As daily, production and gaming settings I use 150A TDC and 190A EDC, and go higher only on like 4 benches (out of 40 or smth). This was with a custom watercooling loop using a crappy Alphacool CPU block. Or check it out in the app stores 5900x not pulling over 142w . I can't find a way to change temp limit in ryzen master, I My 5900x gets 22,200'ish in R23 but that's CO -30 all cores besides 2/5 which are the best cores which are -10 and PBO +25. Up to you Only the extreme test variants can use more than 16 threads in the physics test, the 5900X offers 24. I had to limit my EDC to IMO there's no 'easy' way to OC/undervolt your 5900X. Relevant parts: Ryzen 5900x stock Corsair iCUE H115i RGB PRO XT 280mm AIO cooler MSI Gaming X Trio RTX 3080 Radiator as intake Launch amd zen master, write down the tdc, ppt, edc limits. The default limits under pbo are set to PPT 142/TDC 95/EDC 130. It's a very weird and touchy limit, I'm not entirely sure how it works but I had mine jacked up to 215A as per my motherboards PBO limits and yes, hurray! My multi-core scores were great, but alas my single core speeds suffered. You have to drop them crazy low EDC Limit [A] [160] No changes in scores in CB20 but not so much changes in temps too. 8GHz. 4 Amps on the +12V rail. r23 multi just hit 22982 and it was running 80 degrees the whole time. for Max CPU Boost Clock Override it's better to leave it at 0 and do the TDC, EDC, and PPT shouldn't impact your performance in lightly threaded workloads. You still need to increase the core clocks to take advantage of the higher power limits. EDC does have an effect on performance and you can't lower it until it reaches 99-98% because performance is affected even when its only 70% at the limit. i/e 5950x will pull more power so needs higher PPT (in my case 280), but TDC and EDC at 230A are way too much even for a 5950x. All core boost frequency 4. 36 gHz. SFX 700W PSU capable of supplying 58. RAM is set to DOCP, PBO set to Advanced, PBO limits dialed in and set manually using Ryzen Master (PPT 238, TDC 140, EDC 175, but I've tried many different setups with little difference in performance), Scalar set to Auto, Curve Optimizer set to Per Core 4 fastest cores at -15 and all other cores at -25, and finally Boost Clock Override set to 0MHz but I've tried 100MHz and Not bad with mine all I did was enable PBO and manually set my limits to PPT 195 EDC 140 TDC 130 no curve optimizer no undervolting llc left on auto set my thermal limit to 90c paired it with G Skill Trident Z Neo cl14 3600mhz 4x8gb slightly overclocked and for cooling the Ryzen 9 5900x an Noctua NH-D15 Chromax. CPU temp 82 degree. 46000 volts. Black with the After limiting EDC to below 90A, it would scale better and actually hit PPT. This doesn't seem to work. PBO 5900x on Asus X570-I ITX Motherboard . Enabling PBO can raise those values to the maximum supported by the motherboard BIOS. Have you tried finding the right PPT EDC and TDC limits when I set it to motherboard it performed worse all I did was enable pbo and did a manual limit TDC 130 EDC 150 PPT 180 with no CO scored 22,464 mc 10-minute throttle test sc 1,628 with my Ryzen 9 5900x. I said pbo2 enabled instead of my manual limits and suddenly it's pushing the CPU to 200 Watts under a multi-core benchmark. TDC is rising between 33% to 100% for 1 to 8 threads, then stays at 100%. However on Asrock B550 taichi (at least mine) I set POB advanced and set it manual instead of MB. I'm currently using stock values: PPT: 142W, EDC:90A, TDC:140A. So I changed my settings to -30 all core and messed around with the boost offset and PPT/TDC/EDC limits Best success I had so far is +200mhz and 225/150/170 which gave me scores of 9031 multi 645 single - very impressed with this considering PBO scalar is PBO Limit: Default value was using 145A, Motherboard limit was using 190A. Zen 3 (5900x) and As of finding EDC/TDCbasically I set limits to MB and found the max EDC/TDC, Get the Reddit app Scan this QR code to 5900x should be tuned with PBO CO and power limits All I did with my Ryzen 9 5900x in the bios was enable PBO found my PBO limits PPT 195 EDC 140 TDC 130 with no curve optimizer or undervolting manually set thermal limit to 90c using an Noctua NH-D15 Chromax. Go to ryzen master profile and 'Copy Current', then lower EDC by 5A steps and apply live while watching 'effective clocks'. Idk why, but this is how Need some help with my 5900X + Tomahawk X570 combo. Any idea why this might be the case Before I moved to 80 my edc value was 115/120 and when I ran cinebench on all cores my peak speed would so it probably won't hit your edc limit, single core performance matter more. Like me I think you may have been using the 'AMD Overclocking' menu to set the PBO limits. With this at 105 I lost about 25mhz, and at 110 to 120 lost between 25 to 50mhz so it is part of the fine tuning you can do - I believe around 120 to 130 is typical for a 5900 but again check other peoples numbers, i might not have that right) The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. If you see in Ryzen master, during the benchmarks, that your 5900x is using up 25% of your max PPT limit, and your PPT limit is 1000w, then you can set your PPT to 250w instead. Your CPU is perfectly fine at 90°C fwiw, so there's no need to even worry about it. TDC and EDC seem to sensitively effect performance, too high or too low causing problems - but PPT does not seem to have this effect if TDC and/or EDC are limiting, so i just run 250 PPT. For my 5900X that is 142 PPT, 95 TDC, 140 EDC. 4V which can hurt multicore OC. At the end, I have Thermal Throttling at 67 degrees, PPT = 120W, EDC = 90A, TDC = 75A. My system: 5900x Noctua NH-D15 Chromax with two fans MSI X570 Tomahawk Wifi 32GB 3600 CL18 Asus Tuf OC 3080 10GB Corsair 850 Plat TDC, and EDC while staying at -10 all core and +200mhz. This resulted in certain scores and low temp. I have three cores in the -teens (-12, 14, and -16) and the rest are two at -25, one at -26, one as -27, one at -29, and four at -30. Hey, I'm a new Ryzen boi interested in purchasing a 5900x, the B550-F is cheaper than the X570 Aorus Pro and the X570-F and I'm running on quite a tight budget, so I'm just wondering there would be any disadvantages to running the 5900x on the ROG Strix B550-F for a non-overclocking standard consumer! Any answer will be appreciated. When running multicore tests my EDC is at 100%. PPT is usually around 210-215W for my EDC around 180A. Really extending the EDC and PPT limits don't do a great deal because of temps. I'm the kinda guy who likes to play on his computer, not with his computer. I'm sure upgrading to a 360mm radiator or a bigger cooler would have some effect, but dialing down PBO settings will be more beneficial and cheaper in the long-term. And the all the 3 limites: PPT EDC and Thermal are nowhere close to the limit at 300A, 999A setting: EDC: Default(200A). Your edc is really the limit to follow - the max is somewhere around the motherboard limits that can be set in the PBO menu. Loaded "PBO Limits: Disabled" which uses the default CPU parameters for PPT, TDC, EDC. I've lately been adjusting power limits to see how they affect my score in R23. When I set it using the PBO menu found in the main 'Extreme Tweaker' menu it did correctly set the EDC limit to what I wanted. Turning EDC down from 154 to 125 helped immensely for example, which keeping it around 30-35 away from TDC. Seems like now it stays at 86A EDC / 135W PPT and slightly lower clockspeed. It's an odd one. The 5900x is rated at 105W, but easily draws 140W if you allow it. Tdie: 85°C I expect this helps. The top scorers seem to use very fast memory >4000 MHz - good luck getting that stable enough for benchmarking. When limiting PPT to 200W I get 69C and at PPT PPT can be as high as you want, TDC should be lowered if you feel it peaks at high temps but another (just as good) solution is to use the "Thermal limit" in BIOS. 5900x I’ve seen like to be around the 170 edc level for max scores but some might want more or less peak current What does eco mode change in addition to adding those strict limits to PPT, TDC and EDC? I ask this because ryzen master requires a reboot to turn on/off eco mode, yet no reboot is required to "play around" with ppt/tdc/edc values. Enable PBO and set PBO Limits you should find it for yourself don't use motherboard limits doesn't do a good job find the limits yourself download tools to keep track of scores and temps etc. PPT is the power drawn from the socket, TDC is sustained current limit drawn from the VRM, and EDC is the peak current limit drawn from the VRM. 6% I have the Ryzen 9 5900x all I did was enable PBO and found my limits PPT 195 EDC 140 TDC 130 no undervolting no curve optimizer LLC on auto manually set the thermal limit have a 5900x on a Dark Hero board, Get the Reddit app Scan this QR code to download the app now. To my surprise the voltage bug kicks in when going above the stock EDC limit, which is only 90A for processors with a 65W TDP rating. Run cinnebench, look at temps and package power in cpu-z. For instance, my 5900X is sitting under an Alphacool Eisbaer 420, and depending on the limits I set, the max temp will be: Under ECO limits (the chad mode) - max 60C Under normal limits - Here is a what I did with 5900x to get to run 4. This information can be read on page 353 of the " Processor Programming Reference " PPR for short. For people who want to go further, you should play with TDC and EDC combo for higher results, even a small variation can be enough to squeeze a bit more When you are benchmarking your cpu, see in Ryzen master, what percentage your 5900x is using up for 1000w PPT, 600 TDC, and 155 EDC. Extreme loads like Linpack benefit from even more power and 145/190 was much better than 130 I turned my LLC off and used my motherboard limits on the tdc and edc along with your ppt suggestion. Testing needs to include standard stuff like Cinebench and you need to check each core individually using CoreCycler. For Pbo limits just go by cinebench, max out ppt and tdc and test it, increase by 10 edc and follow the scores, at some point they lower again,every chip is a little This should be a good starting point as the values to pick for PPT, TDC and EDC. PBO: Advance PBO Limit: Manual PPT: 185 TDC:125 EDC:175 PBO scalar: Auto CPU Boost Clock Override: Enable(Positive) Max CPU Boost Clock Override: 50 Then if u want lower temps, limit PPT watts. The selcted PPT / TDC / EDC limits in BIOS. No limit hit. When gaming, PPT limit 280 TDC Limit 280 EDC Limit 230 Curve Optimizer: Cores 1-6 Negative 15, EDIT: OK, so after realizing I drastically limited PPT TDC and EDC with air cooling, I started bumping those limites back up. Those values are maximums for the whole CPU. I'll start tweaking from here.
