Voltage readings compared to BIOS settings

post #1 of 10
Thread Starter 
Hi there guys.

I am in the midst of overclocking my i5-750.

I currently have it on 3,77 GHz, but I can't seem to get stable if I go any further.

I set the vcore to 1.35V in the bios. But I only read 1.319 in CPU-Z when idle. When I start Prime95 or IntelBurnTest it downvolts to 1.269.
These readings are no different from the readings I get in the BIOS monitor.

What should I do to get the full voltage? Or at least 1.3+ ?
I assume I need more voltage to be stable, but I'd rather not push the vcore setting over 1.35V.

I'm a bit scared to disable Vdrop, but could that be the source of my problem?

Thanks in advance!

I believe that's called V-Droop, when you set a voltage in the BIOS but it appears different in Windows.

Could be wrong, though.

well , shut off all power saveing options in bios, not to be a downer but asrock is not the best. They have improve over the last years tho. 8 phase power is good. i had my x58 920 @ 4ghz on it. Update bios also tell us how its unstalbe. BSOD. what error codes. ram timeing right. what speed is the ram. You got qpi 2 times the ram speed. ?

I think you're missing the point, but thanks for your reply

BIOS is up to date. I'm just wondering why it's downvolting to 1.269V when stressing and why it's not at 1.35V as I set in the vcore settings.

I'm assuming the low amount of voltage is the reason why I can't get higher clocks atm.

power saving options. trun them off. I know its lowering the vid lower when stressing. MIte need more volts to qpi or vtt. but More info is needed you say unstable but how.... Bsod what error codes.?
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0X109 = Not enough or too Much memory voltage
So u need to stress it with linx or prime and tell us.... the volt drop in my book is because its not a higher end mobo Not best for overclocking . But i could be wrong

Well, when running Prime95 core 0, 1 and 3 runs fine for 10 hours. But core 2 fails after 5 hours or so. That's my sign of instability.

Turned off all power saving options already.

this is why i dont use prime. I allways got a core failing. like orthos even @ stock. I like linx cpu stress I ran prime 24 hours not a fail, then linx for 2 mins and failed. I used prime 95 for small fft. linx i do drity runs of 10 the try higher mhz or lower vid. for final stress on cpu i run 500 runs. you dont need to run that meny but more the better u are. But ya get linx. here
