Okay will do thanks guys! Also how long do you guys run Prime95 for? So far I dropped the voltage to about 1.345 and its only hitting 90 degrees C MAX on two cores. So yes I will keep dropping the volts a little more... I dropped the LLC to about 50% instead of 75% should I have kept it at 75%? I also increased a little more voltage on my DRAM - about 1.510 volts.

As far as testing for stabability I will keep dropping volts little by little but I am unsure about settings for LLC + Dram volts

I don't run it long, only about 5 minutes tongue.gif, I usually do most of the testing with demanding games such as Crysis 2.

Ah okay ... I am currently at work now so i can't further progress on my overclocking but I read that Max TJ distance should be over 30? Last overclock I had it was still 15's-25's skipping around

On a 3770K I'd try to keep the Prime95 temps in the low 80s. You can try a lower LLC setting as long as you don't get crashes, it's just going to result in a slightly lower load Vcore. You just want to avoid getting so much of a drop that it gets unstable.

Okay currently I have my vcore set to 1.320 and ran Intel Burn Test 10 times and it passed. Also ran prime95 for about 30 minutes no crash or BSOD. I bumped up CPU Fixed Frequency in BIOS to 350 khz from default 250. So far so good... thumb.gif I am going to keep dropping my volts. I noticed in realtemp that my max temps for cores ranges 87-93. This is still kind of high no? How do i get a little lower temps? Just keep decreasing vcores?

Thanks for all your help guys! biggrin.gif

That's still a little high, but you could live with it if you had to. I'd try to keep lowering the voltage though.

Question - does increasing LLC increase the temperature of the cores? I manage to run Prime for almost 2 hours now on vcore 1.295 but i had to bump LLC to about 75% to stop BSODing. So far almost 2 hours and its still going but my temperatures are still about the same range at 100% load =/

Increasing LLC usually causes the voltage to be higher (that's the purpose) which does result in higher temps, yes.

Yes I looked over that ASUS guide and generally most of my settings are similar... slight differences where i current have LLC to High instead of Ultra High as well as different volts of course.

Currently I ran Prime 95 for 30 minutes and passed intel burn test with no problems...
Vcore is set to about 1.290 in BIOS, LLC 75%, CPU Current Capability - 120%, DRAM is 1.510v & CPU Fixed Frquency - 350 khz. Attached is a screenshot I just took.

Temperatures seem bearable, what do you guys think? I will try to drop it closer to 1.280 volts if i can; hopefully the temperatures might lower by then.
