Help me OC my i7 930 higher!

post #1 of 7
Thread Starter 
So I have it a 4.2 right now, which is pretty good, but my temps really low. I'm running linpack right now and at 100% I'm only at 65 degrees. I do have a Silver Arrow, and I'm thinking I can probably push my OC even further.

My vcore is at 1.29
QPI/Dram core is at auto
Dram bus is at 1.64

all the good stuff (spread spectrum etc) disabled
Load line enabled
C1E disabled


Oh and also I just grabbed the 8GB corsair Vengeance C8 kit (I know its not triple channel but hey, I'm getting LGA2011 anyway)

Also, Ideally I'd have my CPU at 4.2ghz, and my ram at 1805, but that doesn't seem to want to work out for me for some reason. If I bump up my ram it goes to 2k+, if I bump up my cpu it goes unstable.

Ideas?

Theres a wall sometimes that you need big bumps in vcore to get over. I'd see how far you can push it on Intel's max 1.375V, some people go much higher, just watch temps. Is QPI/DRAM core your VTT? Its for the uncore so its the second most important voltage after vcore and should be put on manual and tested at different levels to see how it affects your OC.

I am at the same 4.2 ghz that you are with 1.29v and HT on. For me to get a stable 4.4ghz with HT on I need 1.39v and I can't go any further because of heat and so I backed off to 4.2 ghz again till I get water cooling. Even now at 4.2 its kinda hot because this room is usually warm but I'd try to stay under 75c.

you know, its funny, I've never known exactly what QPI/DRAM core voltage is. I'm pretty sure its not "Ram Voltage" as people often refer to, because it seems to want to default to 1.4.

qpi = quickpath interconnect controller voltage, dram voltage is exactly that uncore has it's own voltage as well = known as either uncore v or imc or ich

some RAM + CPU combos need higher QPI. Some need lower. Never set auto. Try 1.35 and see how high you go.

124 BSODs indicate higher QPI needed. I've seen recommendations of up to 1.6 off of Corsair/Patriot/G-Skill forums. It depends on the chip.

Slight correction- 124 is indicative of a need to "adjust" QPI in either direction, not necessarilly just increase.
