I might be able to help out a little this week.

I got my X3440 in along with mobo. I do not have a good cooler yet, but might be able to get something to work, will have to see.
I have 2 different sets of identical ram. I will run these in the lynfield and the 920. I will get the same oc on both. This should keep any variable out. Except the fact that lynnfield might require more juice to get the same oc due to on-chip pci-e.

Anyway, I do not have a killawatt, but will try to help out as much as I can. I am curious to see if I wasted my time going lynnfield or not. I hope not as I could have built another 920 rig for the same price or a few $ more. Oh well, trial and error right

I should have lynnfield up by tonight and might have to readjust one of my 920's to match. will then try to compare.
