BZB,
Do you know a way to cap adaptive volts on ASUS boards to something manageable when running AVX (IE, 1.2000V at most), as I feel my board's UEFI volts too high when it's not even OCd to 4GHz with 4-core multiplier. I get like 1.275 or maybe more with prime95 stresstest (which is far higher than any other app admittedly; I still don't like it going so high.)
I tried setting manual volts in UEFI, but ended up pegging the CPU at that voltage at all times even when not loaded at all, drawing power and belching extra heat needlessly.
Yep, that's pretty much why you need adaptive voltage and not the standard VID.
My motherboard is the Z87-Pro, so depending which motherboard you have, the instructions may be different, but you are looking for the same things, and a lot of the Asus UEFI are very similar in most respects.
1. Boot to the UEFI.
2. Switch to Advanced mode.
3. Go to AI Tweaker.
4. Scroll down to CPU Core Voltage and change it from "auto" to "adaptive". A new adaptive voltage field should appear.
5. Enter 1.200 into the new adaptive voltage field. Don't forget to hit enter after you've put the numbers in.
6. Save and exit.
If you use AI Suite, you should see the difference on the TPU page under the CPU Core Voltage pane. You can do testing in this same part of AI Suite to find the OC adaptive voltage that you like by changing this setting. However, manual changes like this are not then saved to the UEFI, and are lost between boots. You need to go into the UEFI and make the changes there to make them stick. Only when you run the 4-Way auto-tuning are the settings then saved to the UEFI. Everthing else you change manually in AI Suite is not saved between boots.
Rather than using Prime95 (for the reasons I outlined above), I've been using MediaCoder X64 to encode MP4s using their experimental segmented encoder. This is a real world application that is trying to load the CPU as much as possible for efficient encoding, it won't pull as many volts as a torture test, because it's actually doing other encoding calculations at the same time, not just trying to heat the CPU.
I've found that dropping the adaptive voltage to 1.200 makes the encoding run massively cooler, and even Prime95 behaves itself a lot better.
