Getting above 4GHz on i7 920 C0 Bloodrage GTi - Page 2

post #11 of 16
i appreciate this might not be much help, but my i7 920 used to hit 4ghz easily at 1.28v...anything over 4ghz wasnt happening...even with high volts!

how do i get 21x? nobody seems to answer that question...

well, if you can't seem to get x21 multi, i'd say just stay with 19 or 20 for now

do you have a program that can monitor voltage in windows?

best bet to avoid bsod before reaching windows is to set your multi to say, x20, set your ram to as low as possible, still disable all the options i told you so in the cpu feature section, including PPM, and yeah, turn off turbo.

then basically just leave the qpi & uncore ratio, ram latency, and all voltages to auto, boot into windows and check for temps and voltages, make note, then dive back into bios and set everything what you just wrote down manually, and start working your way down (voltage wise).

you said you're stable with bclk set to 210 right? then with x20 you should get to 4.2, but since it's C0, don't expect it to work (be stable) without a huge amount of volts...if you cant get it stable under 1.4 on air, then just leave it as it is i guess. afterall it's fairly well known that the C0 920s has their limitations when it comes to overclocking

oh and btw, bsod 101 means more vcore, you might need this later if you haven't already come across it, i got it from ocn a while back when i was messing with my 950, would point you to the thread, but i saved the codes, so it's easier for me to find...

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
0x3D = 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
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

i tried doing 220*19 but with no avail. I get a 101 error and that was at 1.38v Whats the max voltage for these things? 1.4 is it?

well, if i remembered right, intel's recommended voltage is 1.35, lol. but i guess as long as your temps are ok, it shouldn't be a problem to push it a little further, but to leave it on 24/7 you're running on your own risk. there are people using more than 1.4, but i think they're under a proper loop, all depends on temps under your h70 really...

you tried everything auto yet? i guess you can try 200x20 first? wonder what does your mobo set the vcore to @ 200x20

anything with an even multi and my chip refuses to boot. Oh well, i got 4.1 stable, looks like its the limitations of my chip. Thnx guys
