Core i7 920 Overclock

[Frosty]

All the comps for my new system are in the mail. It's been a while since I've built a system from scratch and overclocked so I'm posting here to check my logic.

I plan on getting trying to get the base clock to 200mhz (watter cooled 4x120mm rad). I'm also using OCZ ram rated at 1600 Mhz. If I leave the memory settings on auto, and the default memory multiplyer is x8, 200mhz x8 = 1600. So my ram should run just fine with auto turned on since its rated to run that fast right?

I know I'll prolly have to boost the vore to 1.45-1.5 to get the CPU stable at that clock, but I should be able to run my ram at stock volts since its rated for that speed. I suppose I'll also have to hit 1.3 or so on the QPI voltages.

So if I turn off all the power saving features, alter the vcore and QPI voltages, and leave everything else auto...I should get a stable OC to 4.0 GHz (provided my chip doesn't suck and I have to turn the base clock back down).

Does this all sound right?

The new 45nm chips don't like voltage above 1.35 much, definitely keep it below 1.4 if you can. Its not the temp I'd worry about but there is a bit of danger of just frying the chip with too many volts.

bclock of 200 is ambitious, most chips don't seem to like it. 4ghz could however be possible by for example 210*19. I'd try overclocking the ram a bit, but it's hard with multipliers that go with steps of 2x.

Apart from that everything seems ok Make sure to post a buildlog once you reach 15 posts

Run with a lower CPU multiplier while you are bumping up the base clock to 200Mhz, that way you can make sure that the memory subsystem is working together nicely before you start factoring instabilities from CPU overclocking.

WOuld be a good idea to find out where the max for each component is and then add it together. working out whats best.
