Also.. before, on manual Fix voltage...my CPU would not take any less than 1.385 Bios (1.392OS) to run RB 2.43, Aida Stress test at 5.1 / 5 uncore ) now it boots at 1.136... spikes for a second to 1.392 but under load its a constant 1.360 and no BSOD so far ?! I am really confused... Adaptive basically lets you run higher voltage in Bios and actually uses less in OS ?!

Edit:

It seems no matter what I do on Adaptive voltage under load it goes to 1.360 - 1376 which results in BSOD. Will play with it some more.

... yes I know, you described that in the post I quoted.
AID64 sounds like a driver issue if some type. you did load the chipset and ME driver.. and have a clean install of windows and not moved from another rig? (Win management interface, and machine interface need updating fir kaby)
If it needed 1.385V on manual, it will use the same on adaptive. first KNOW what voltage works with manual override, then just set adaptive to that same voltage, CPU SVID on Auto should work, if not Enable it for Adaptive. change nothing else. if the voltage still is not loading correctly, set IA AC and IA DC loadline to 0.01. This adjusts the adaptive voltage load line.
Any difference in bios set voltage and during load in windows is LLC (or IA loadlines)

The CPU does not have a problem if it works fine with stocks speeds, I would say the memory has a problem.

those real bench temps are too hot for my liking... what cpu cooler? (fill out rigbuilder and add it to your sig block )
and is it down clocking and down volting as originally asked????

You're using adaptive voltage. It's perfectly normal and expected to have lower Vcore voltage when idle. From my experience AVX workloads cause bigger Vdroop or not supplying enough voltage then I set an AVX offset. I solved it by lowering the adaptive voltage by roughly the amount of Vdroop and adding that difference to the offset.

If you have temperature issues, apply an AVX offset 2-4. If you don't use softwares that have AVX code (there aren't many) then you're better off with an offset.

Ok, I swapped out my Gigabyte Gaming K7 for an ASUS Maximus IX. Same CPU, but I've noticed that with the ASUS board, setting the same Vcore seems to get me even better stability. For instance I would fail Prime 95 in 2 minute son my Gigabyte board at 1.28 Vcore, but on the ASUS board, I've been stable 15 minutes now. Obviously more data is needed, but it's still interesting to observe.

I think once you factor in Vdroop, the ASUS board is actually even delivering less Vcore. I always log down what my Vcore @ Load so I have a good understanding of what a stable voltage is at load. So whereas the Gigabyte board supplied 1.284V and failed in 2 minutes, the ASUS board is only supplying 1.264V and is still going strong. Additionally because of this slight Vdroop on the ASUS board, I'm actually getting lower temps.

Maybe my old board was defective or something.

Firstly, adaptive Works!...volts jump up and down with core freq...Cpu goes to 5.1...volts go up...Cpu goes to 4.1 volts go down..
The problem is that I had to add 1.425v in bios to have 1.392 in Os under load because whenever I apply load, volts go up...but not high enough... and using any less in bios eg 1.385 or 1.395...result in having 1.360 in Os under load and a BSOD.

I think my OS got corrupted all of the sudden as well so I am going back to point 0..
Gonna clear and reinstall Bios, put everything on default and start playing just with core voltage and see where that leads me.

Cooler is Noctua Nh-D14 + 1 Noctua 3000 ippp cooler for v-ram / dram...gonna re-seat this today as well as the cooler is touching the GPU which sits at a funny angle now...I either hit the GPU or if I turn it around I hit the ram...everything is tight smile.gif)

I think my strategy was wrong in the first place going: Stable manual volts --> Stable RAM ---> Cache ---> Adaptive ---> Lower Vols...so as said I am going back to point 0..will report later.

You got me wrong, I have lower volts under Load!

I had to jump from 1.385 manual fixed volts (BIOS) stable ...to 1.425 adaptive (BIOS) stable

That 0.160 added voltage gave me a whole bunch of extra heat to take care of under load and I am hitting 91-93 Celsius after 10-15 min of RB. Before it was 75-80 Celsius (Cpu package) after 3-4h of RB.

Adaptive works great, except whatever value I set for the it llc 3 up to llc 7 or volts (Turbo) 1.360 to 1.395..when I get in OS under LOAD it drops to 1.360 - 1.376 for some reason which is not sufficient for my CPU and I BSOD.

Only way to make it supply necessary volts under load is to put turbo under Adaptive to 1.425 ....that gives me 1.392 under load...
