Best HWMonitor and most others will report the offset value, but AIDA64 will report the actual VCCSA voltage even when you use an offset. The wording of these voltages may differ depending on your motherboard. And they replied everything under the max value of 1. My issue is with my old kit 2x16, 16-18-18-36 at 3200mhz my vccio and vccsa would both be 1. This says the max voltage for the System Agent and Integrated Memory Controller is 1. 92V on non K 12th gen SKUs thanks to the reintroduction of IVR (Integrated Voltage Regulator). However, good DDR4 memory will run at 1. Did I just instantly degrade the SA by setting to 1. 24 for VCCSA. 36v (or whatever voltage) is more detrimental than a much lower wattage load at 1. Otherwise they were reasonable. 33 x 100. Add a Comment. 632V. 2v -1. VCCSA (System Agent Voltage) has usually very little impact on stabilizing any OC. 080v popular opinion is that VCCSA is System Agent Voltage, and it stabilizes or helps overclock BLCK, while VCCIO (commomly known as VTT/QpI) Also System Agent does directly affect the IMC for Haswell and I have a Maximus VI Formula motherboard and a 4770K which I'm trying to get stable and one parameter where I have had some mixed information is what to be considered as a safe VCCSA voltage?

Normally I'd agree, but only with undersized coolers (coolers that can't keep the temperature fluctuations of 0 load to 100% to under 30 deg C (40max). 2左右就行了，4500给1. 368v and goes up to 1. 597V , when setting it manually the red values start beyond 1. 1v would mess with the DTS sensor that report core temperature and the values would be a good 20C under the spec voltage of PLL =1. VDD_IMC is an important voltage for DDR5 overclocking, it's basically the memory controller equivalent to DRAM voltage for DDR4 Yeah I noticed that on the first day of messing with voltages, and luckily, I read somewhere that the voltage is usually set to the DRAM VDDQ, so I set it manually. I don't think above that, even in max frequency. Does anyone have any experience with this along the lines of the VCCSA and VCCIO recommendations for each frequency? Locked post. I think micron E die also has a pretty high safe voltage limit, but it's definitely not 1. I removed one stick and the tests passes fine. They are actually on the same rail AFAIK. 15 and above, and only goes up to 1. 095V CPU PLL. Hey guys, What's the voltage range of VCCSA and VTTCPU on ASUS X79 motherboads?

Staff member. Certain dies can go higher on voltages than others, that's one of the reasons Samsung B die is so coveted for OC because you can just throw voltage at it and it will be just fine. hino said: As long as it's within spec, it's "safe" voltage. Try 1. 2k 126 Posted September 14, 2016. I just recently went to Z370 as well. Due to the fact that too high of a voltage can cause instability as well, it may be quite annoying to fine-tune this voltage. i recently bought a 7600 ram kit with a 13900k, i was getting errors after 5-10 minutes so i knew i was on the line of stability. Anyway, the big problem on my board is that VCCSA and VCCIO seems to be in a sort of read-only state. For my current system: DDR4-3600, Gear 1, Along with safe maximum voltages for 8700k, mainly I'm looking for what will help stability for above said example. 35V VCCSA now FYI. that's another topic I can't find info on other than just try it and see. . There are certain ranges of voltage which may exhibit worse stability, once you go past them (higher or lower) stability improves once again. Is it really safe to push that much voltage through? Gskill Reply: Hi Dan What's the safe max limit for VCCSA in 13900k and DDR4 OC? I heard you can't have it too high like for 10th gen or you can kill your CPU My gaming rig CPU: i9 13900K 5. 25 V. I replace that stick with the previously removed stick and ran the test again auto vccio and vccsa voltages are usually unnecessarily high. I have set already VCCSA but can't find VCCIO anywhere. 270 VCCSA 1. now i need found the correspondence of hwinfo V1 voltage, I already did everything to find out which voltage corresponds, i have increased and lowered voltages of all items in the bios to see, maybe, if there was something similar but nothing, maybe a bad reading of hwinfo64, My concern is that at idle this v1 voltage is maintained at 0. This system is on a custom loop but it's only a 240mm radiator with some questionable chinese ARGB fans mounted to im seeing even XMP modules going to 1. I've also read that VCCSA should be kept below ~1. 3, likely in the area of 1. VCCSA at auto gives 1. VCCIO There has been a fair bit of talk about the auto voltages being applied on the z490 platform, most notably auto vcores and crazy high VCCSA/VCCIO Skip to main content. What's the highest safe voltage I should use? P. I wanna say right now on auto it’s displaying in bios it’s getting about 1. In documentacion for Broadwell-E I'll definitely give your suggestion a try with the uncore/ring voltage and VCCSA to try to push it further. 4V overdriven. I've never been able to get that high because when I push past 1. 3V, Vccio max 1. My CPU VCCIO is I wouldn't go over 1. i7-8700k on a z390m board For example, with XMP enabled and VCCSA on auto, my motherboard would set the VCCSA to over 1. HWiNFO says my SA voltage is at 1.
