| ASUS P6T V2 DELUXE overclock advice
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.

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. | |

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 possibly ram.
Might read this guide. It uses your motherboard so it should be pretty accurate to what your actually working with. Intel Core i7-920 Overclocking Guide - X-bit labs

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? | |

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.
