i5-2500K 4.8ghz at 1.26v - Page 4

post #31 of 41
I highly doubt you can run 4.8 at stock volts like you claim. 1.25 is basicaly stock.

This is why i made the thread, i don't believe it either, so i was thinking the voltages are displayed wrong...

Anyone know how to view bios voltage from windows?

Have you tried other voltage readers.. Like HWmonitor, HWiNFo32 ? I use both and they work perfect for me.

ill give HW monitor a go

What was your VTT set to?
If it was set to auto, then the vcore was displayed correctly. I have that board so I know when it does or doesn't show voltage correctly. Incorrect vcore reading is +.03v higher than VTT set in BIOS (Auto=1.05+0.03=1.08). As incorrect supported cpu-z reads the vcore as VTT.

Anyway, why did you go back to 4.5 ghz?

Try 4.8 again and try doing prime blend with a BIOS setting of 1.30v, with LLC1, and I guesstimate that this will give you 1.272v LOAD voltage. (this is assuming you're using a BIOS version OLDER than F3 final (e.g. F3G for UD5 or F3H for UD7 or F3D for UD4). If you're using a BIOS with 10 levels of LLC, I can't help you; try backflashing to a F3 beta (not final) BIOS with the standard, LLC1 and LLC2 only settings. If you check xtremesystems.org, you will see that the most reliable bioses for voltage are the F3 betas. The ones with 10 levels of LLC are buggy and cause vcore spikes, and this INCLUDES on the Z68 boards, too. C_N has a board that can do 5 ghz LinX stable with 70C load (UD5 B2) but when he tried the Z68 UD5, his temps were 80C (due to +0.05 higher vcore needed at load) to be stable, then he BSOD after restarting the computer after the test. He hates the 10 LLC levels....

Im using F2 atm.
I went back to 4.5 because IBT/AVX was pushing the CPU to 86degrees celcius under maximum stress.
The 1.272v is correct, it was diplaying that under full load, ill run prime95 blend now to get an idea of what the temps are.
the Vcore in BIOS is set to 1.3v
Thanx for the reply, ill give it a go..

PS. From an experienced point of view, how are you liking the UD4?

just solved a BlackSOD!
Yikes!

I do think that CPU-Z is bugged...
CPU-Z
This is a validation of my 1090T @ 4.00Ghz with 1.300v
Before any of you say that it prolly wasnt under stress... Chech out the pics bellow.
No! Im not bragging.
Im agreeing with the OP and showing proof's.

Those results don't help much because you're using downclock idle+offsets. Turn off power saving and eist.

See if you can get a 12 hour blend at 1.26v. You won't degrade your chip at that voltage. And if you try that, read the rules of the stable club thread and post a result there.
