You should have just said that in the first place as this is what this topic was about the whole time. Thank you though. I really apricate your feedback. You have helped a lot, especially on some of my other topics.

Do you think raising it will actually help though? Or do you think auto should be fine?

I've got cstates off of course. CPU VCCIO is 1.056 and CPU VCCSA is 1.136. They aren't high at all. I've also ran the exact same test before for 19 hours with close to these temps. Temps were average in the 80's. The only difference is uncore was 43.

I'm not worried too much about my chip, I upgrade every 2 generations, sometimes sooner. I'm also not gamming. My main concern is, do you think the crash is because of two low of vccio and system agent? Or do you think it is the vcore?

I've got 2xx360mm rads and a 240mm rad in a custom loop. My temps aren't that bad. 85 average on full load with vcore averaging 1.395 all with 8x Nactua 3000RPM fans on full blast! (Yes, it is very loud)

Just a quick hopefully simple question, but do you think System Agent Voltage will help much when overclocking CPU Cache? Or is it better just to be left at auto unless unless overclocking RAM (Even then though, there is a separate System Agent Voltage for RAM overclocking) CPU: 11900K Mobo: Asus Maximus Hero XIII Before I was using VID Offset, but right now I'm going with just manual vcore. I'm still testing, but as of right now, this is what I've got. LLC6 vcore 1.49 XMP1 52 all core (Including AVX2/AVX512) 46 Uncore The voltage I used prior to this test was 1.48, and a bit more than 9 hours in running blender bmw it crashed. I'm assuming there was a BSOD. (Not 100% because I was at work) I'm worried that raising vcore wont' really do anything, and I should be raising something else (System Agent Voltage). Should just leaving it on auto be fine? Or should I really raise it, check for stability then try lower vcore?

That is not accurate. In ASUS Bios, as you get lower, you get more vdroop. If that wasn't the case, then LLC8 would not yield me pretty much the same vcore for load as idle.

LLC8 should have no vdroop as it is the highest level on my board. There should just be transients I think is what they are called. That or is it called just dips and spikes? Thank you for those benchmarks, I will for sure try them. Also, I did not have any static voltage set whatsoever. It has always been on adaptive.

Well LLC is known for keeping a high Idle Voltage. I have yet to try LLC7 to see if I get the same as I did with LLC6. But right now, I'm using FFmpeg with uncore at 46 to see what happens. Though that may be pointless as I'm not sure if FFmpeg benefits from fast memory..

Changing to LLC6, I'm seeing idle voltages under 1v now though. To be specific, it's about 0.746... Seems like now I'm kind of back to the drawing board. Isn't 1.4 idle at 800MHz bad?

At idle right now without c-states and min cpu state at 100%, the min CPU Power Package is at is 112. Changing min cpu state to 0%, I get min 86. With C-States set to auto, I get min 56.. However, idle voltage is 1.43, and I'm guessing this is because of LLC being at 8?..

Right now at idle, I think I'm at ~137W, you're saying even with c-states and a different power plan in windows, it will only be 2 - 3 watts lower? I honestly thought it would be lower. I'll have to test that.

I mainly just do coding, (Usually C++) and some video encoding focusing on compression using HEVC. Sometimes I do video editing and 3D designing. The voltages I'm seeing at idle are only that high because I have c-states disabled and have min CPU state in power plan in windows at 100%. These settings are only temporary. Once I finish overclocking, I'm going to enable c-states and set min CPU state to 0%. Doing that, idle vcore will be under 1v. That is why I don't want to use fixed vcore. How can I lower what the vcore will be? I tried lowering VID for 5.2 even more, and that had no effect on what vcore was.

Thank you for all your input. I was very worried about haveing LLC@8 and was worried it would kill my CPU. Your input has helped a lot. Thank you.

CPU: 11900K MOBO: Asus Maximus HERO XIII Vcore mode: adaptive with +0.001 offset XMP 1 5.2Ghz all Core AVX2 and AVX512 Offset: 0 AC/DC: 0.001 (Or 0.1 or whatever the lowest) LLC: 8 VID for 5.1: -0.15 (Only to allow VID for 5.2 to be set) VID for 5.2: -0.22 Average vcore under load: ~1.394 Average vcore idle: ~1.403 Max vcore: 1.421 Max CPU package power: 413 Average: 374 Before I enabled AVX, uncore was 4.3 After enabling it was 4.0 Tests I ran: Without AVX: Blender BMW for 20 hours (That was however with LLC4 and VID for 5.2 -0.04. Only difference for vcore is that idle was 1.51 and instant 413W within less than 1 min full load. Whereas with settings above, I only saw 413 with AVX both enabled) Last night I ran ffmpeg encoding a 4K movie using libx265 at preset slow. 8 hours with settings above and no issues. Now onto uncore.. There is this setting I needed to disable in bios to actually be able to get anything higher than 4.0. When doing so an setting uncore to 4.3, obviously vcore goes up. This case it went to ~1.43. Didn't test for long. There are these other voltages in bios such as System Agent, CPU VCCIO, Mem VCCIO etc. (There was also one that had the option of using adaptive) I know most of them are for RAM, (Atleast that is what I am reading, but I am reading that some of that has changed) What I'm most curious about is, is there a voltage that I can change that will "Only" (I and I use "Only" very loosly) that will help cpu cache and not raise the vcore? Or no matter what I change, vcore will be affected? Now I know there isn't much benefit at all for higher CPU cache for most situations, but I still want to OC it. Any help is much appreciated. (Sorry if this post is all over the place)
