hmmm.... that's why I ask about 124 error:

0x124 = add/remove vcore or QPI/VTT voltage (usually Vcore, once it was QPI/VTT)

but if it's 24 boot windows in repair mode and press Auto Repair.

I have been keeping a spreadsheet with the OC attempts I have done today. I have omitted any redundant stuff, so if something doesn't work on the sheet, you can assume that the voltages below it don't work either. I have them in mine being that I picked a starting point and if I didn't get it stable, I increased until I got a boot and those are in the sheet.
Spreadsheet (Click to show)
345

I have it color coded for ones that passed. The ones in black failed. Note that a TON of sets ran fine for the original 10-15 minute tests I was running but they ALL crashed at 25 minutes of Prime95. The only times Prime95 failed, it gave me a "Prime95 has stopped responding" and then I had to exit the program. ALL of these occurred at 25 minutes too. I was using a custom blend with 90 percent of available RAM and running the FFTs for 2 minutes each.

For the max voltage, the lowest number is the minimum voltage I saw on load, the middle is the most common voltage I saw, and the highest is the absolute max. The voltage fluctuated a bunch at load, is this normal? I noticed that WHEA errors coincided with the times that the voltage would be at the low end of the load values. Is there any way to make it fluctuate less? Note that I started doing this later on in trials, the earlier ones just show max or the range.

For the times, if it was stable, I wrote the time it was stable for, and the time I ran each FFT.

I stopped at 45 for a multiplier because I didn't want to push too much voltage through this chip, as I would like it to last a few years. What is a safe voltage to have it on load for it to last that long?

Where would you guys go from where I am now? That last run actually just finished and ran 30 minutes without problems.

I know there are tons of questions in this post, but I would really really appreciate it if you could answer them all smile.gif

Thanks again,
Big Al

4.8Ghz

It spiked to mid 90s until my H100 spooled up. Now it's sitting happy mid 80s on "in-place" prime95. Blend makes it high 70s with a bit of poking low 80s.

While doing this test I am playing Pandora and browsing Reddit as well.

What do I win?

Oh, and I lapped my CPU.

did you test before lapping???

Yea, it was about a 6 degree drop. I don't have screenshots though.

Here is newest. Was able to drop the v-core and complete Intel Burn. Going to keep dropping the volts on everything until it flips a *****.

that is a nice gain from only lapping! Nice job!

During steady states of load the voltage shouldn't change unless the VRm gets too hot or the CPu gets too hot. However during 100% you can see changes int he actual loading on the CPu even though windows reports 100%, you can see this through the CPu temperature. However if it happens randomly then it probably isn't different loading states. Now you can see that happen in IBT, Prime95 too, but not as much. Try lowering the OC and the voltage, and see if the same fluctuation occurs, like it would occur at the same time in the same pattern. if there is no pattern that shows up at both OC points, then something isn't set right or the system can't handle it.

You are doing a really good job however! I like your spreadsheet!

I still have everything turned on; speedstep and the C#s as well. They don't seem to lower heat at all and I am stable so I'm just going to leave it be for now.

Sin, you are a hero among men. Thank you.

I tried the stock clocks and voltages and still had the fluctuations at load. Could it have something to do with me disabling C3, C6, and the package C states (I think it was like C2 and C4 or something)?

You mentioned temps could cause a problem, but the hottest I have seen it get is 72C at the current settings, and that was with IBT set to use 90 percent of available RAM.

If it matters, I followed this guide except that I don't have the PLL on auto. I would have followed yours, but the different names of settings kept throwing me off frown.gif
