Thread: ASUS P6T V2 DELUXE overclock advice

Started 2 months, 1 week ago by waynezo
I have an i7 920 and want to do a stable overclock of about 3.5 Ghz. I'm looking for a recommended tutorial. I have a Prolimatech Megahalems heatsink. any advice will be appreciated.

Start there and see if that helps.

Ok, thanks KarmaKiller

I used the settings on the 2nd video. I got an OC of 3990 but not stable. My multiplier is 21 not 20. I have the DO version processor, is that supposed to be the better one?. To get stability should I just lower the BCLK? Temps went up to 79 using prime 95.

KarmaKiller replied 2 months, 1 week ago
First off, 79°c is fine for the I7's. They can run warmer then 775 CPUs. I believe 90c is the threshold temp. As far as the OCing.. D0 is the better revision of OC'ers. You could lower the BCLK down and that would probably help with stability. But in most cases, those revisions can do 4Ghz easy, so I think something else is possibly holding you back. Maybe v-core, or ...

I used the bios recipe from the x-bit labs article, but can only get stable OC at 175 bclk 3500mhz. Once at that speed while surfing with Firefox and running prime95 computer froze. Is prime 95 testing supposed to be done alone?

KarmaKiller replied 2 months ago
No, not really. In fact, the more stress/load you put on the CPU at that point, the better. What's your vcore set to? Ram speeds/timings? I know your chip is capable of much more then that, so something else has got to be holding you back.

Can you post a screenshot running 3 instances of CPU-z, showing CPU, Memory and SPD tabs. You may need to right click on the cpuz.exe file a choose "Run as Administrator" to get all the information to show up.

I can zip all 3 of my 920-DO's right up to 185 with a 21 and no problems and no voltage changes. May want to take a look at the thermal paste/ heatsink mounting.

This is with bios set at 175 BCLK and Turbo v set at 190 BLCK

Have you manually increased the DRAM voltage to 1.65v? According to OCZ it needs to be that high running at 760MHz. Can you run Prime95 small fft for 30 minutes w/o error? How about the Blend test?

I now have a stable overclock, but I'm not sure what I changed to fix it. Could changing DRAM from 1.64 to 1.66 make the difference.
