So I built myself an SR-2 System. Got a link over in the WC forums: http://www.overclockers.com/forums/showthread.php?t=657190&page=10

I've never OC'd the newer Intels, so this is a learning experience.
I've gotten it down somewhat, but I keep seeing a discrepancy on a few things.
I've seen some say no more than 1.4v on vcore, some say no more than 1.45v.

I've got the Bclk up to 190 so far with the CPU multi at 18, but knowing where it's not worth pushing past would help alot.
 
Got an update.
I've got it running stable on these settings so far.

Bclk 173 @ 25 Multi = 4.337Ghz
VCore 1.39375v on both
VTT 1.35v on both
IOH 1.35v
VDIMM 1.65v
Uncore 12x
QPI 4.8GT
RAM @ 1066, puts it at around 1500Mhz and timings on Auto for the time being.

If I push bclk up even 1mhz it won't pass prime/linx.
I can live with this, and if this is the limit, i'll play with voltages to see which ones I can reduce, since I don't think both CPUs need that much.

But if anyone has any suggestions that might push it higher, that would be welcome.
