Congratulations on the new system
Overclocking i7s aren't hard at all. Try leaving everything on auto and set the CPU multiplier to 20x and the BCLK to 190. The memory should be run at its default timings and as closest to its rated speed as you can get it (1800mhz)
See what that does

Andy,
Thanks for the tip, leaving everything in auto seems to have done the trick, I'm now up to 3.6Ghz with a bclk of 180, any higher and it fails to boot.
One thing I have noticed, in auto my mobo seems to shift the multiplier around on it's own, it went up to 21x at one point. I didn't think the 920/940 could do this (well, I thought they could only go down, not up)?
My temps at 180 seem to be up around the 80 Deg C mark, is that ok? I know the max is 100, but I assume that's a peak temp, not an "everyday" temp?
Also, Andy, thanks for your help and clarification about what an i7 system could do, I'm glad I took your advice and went down this route, FSX is really coming alive now!

That happens when you haven't set up BIOS correct. You have to disable settings in your BIOS that automatically changes the multiplier settings, core voltage etc. Read that article and study the BIOS images carefully.My temps at 180 seem to be up around the 80 Deg C mark, is that ok?

What program do you use to read the temps? Download RealTemp v2.90 and set TJ Max to 100. This will give you correct readings of the temp. If the temp is about 80C when running the CPU on 3.2GHz I would suspect that the cooling isn't working as it should. What environment temp do you have (room temp)? Is the cooler mounted towards the rear end chassi fans? It's important that the cooler blows the air out of the chassi.
The Cooler is mounted vertically so it exhausts out of the 200mm fan at the top, it lines up perfectly. I using realtemp. I'm at 80 degrees while running at 3.6, not 3.2.
Room temp is quite high, around 24 degrees C.

Ok, thanks for the info, I guess my room temps are pretty high. I'll turn HT off, and all the other "power management" features too.
It was my understanding that RAM voltage should be below the specified max for the stick but also within 0.5v of the QPI/DRAM voltage? I'm a little confused about the specs of my ram, I see more than one voltage listed here: http://www.valueram.com/datasheets/KHX14400D3_1G.pdf (see description, voltage ranges from 1.5-1.9v) Can anyone clear this up for me?
I'm actually away from home at the moment, I'll try out your suggestions and report back!
Thanks,
Ric B.
If you're running an i7, the voltage of the RAM should never be agove 1.66v period. You WILL BURN YOUR PROCESSOR if you do. I guess if the memory is rated at 1.5v then go ahead and do give it that voltage and leave the QPI at auto.
I think what was said in the link you gave was that they tested the memory up to 1.9v and it was stable, but it's standard rating is 1.5v
