Question about my i7 overclock

post #1 of 8
Thread Starter 
Been around for a while and have usually used amd chips for OC'ing. Finally bought my first intel in over 10 years. Bought the i7 950 along with an evga motherboard, g.skill ram, etc etc.

Right now I am OC'd to 4ghz. CPU-Z says im running @ 1.329 vcore and cpu temp is 45C with individual cores not exceeding 60C under 40+ min of Prime95 =)

That is not my concern though. When booting into windows, after I have entered my password, there is an unusually long wait time before my desktop shows up. Roughly 10 sec sometimes more. Would this be due to an unstable OC? or something else? I would assume it has something to do with the OC as when put at stock settings, my desktop loads up real fast.

Any suggestions or questions?

*EDIT*
Another question. I notice in Prime that some cores are finishing tests sooner than others.
Ex:
Core 1: Test 2, 4500 Lucas FFT 896K
Core 2: Test 2, 4500 Lucas FFT 896K
Core 3: Test 3, 4500 Lucas FFT 896K
Core 4: Test 5, 4500 Lucas FFT 896K

Thoughts?

Try bumping up the voltage a bit. This would happen to me, too, when my OC wasn't completely stable.

Also, have you done any stability testing with P95 or LinX?

Currently running P95...

And which voltage to bump? I take it vcore? There are so many new voltages with the i7...its redic

Yep! Also, what voltage are you using for your RAM?

I would recommend between 12 and 16 hours of P95 and 50 passes of LinX to make sure you're completely stable.

ur temp looks not bad on full load , but if u find unstable oc, u probably have to check ur voltage core and qpi core, but voltage core is the major probelm , if u see unstable oc , u might have to tweak more voltage core

Thanks i like to run P95 for 24hrs...personal preference. Ram voltage is @ 1.65v...9-9-9-24 for now.

Man, your temps are awesome at full load with that much voltage and that seems like a lot of voltage for a 950 at 4.0 GHz from what I've seen on this forum. You may have some instability from too much voltage or maybe your VTT voltage is too low or your RAM is unstable. What is your VDIMM? QPI voltage? What are your RAM timings and what is your RAM rated for? Are you running small FFTs in P95? How cold is your room? What utility are you using to measure core temperatures? I ask because 1.329 volts at 4 GHz should generate massive amounts of heat. I didn't think 60 degrees would be possible under those circumstances without good water cooling unless your ambient temp is like 15 degrees C.
