i7 3770K 4.9ghz

post #1 of 7
Thread Starter 
Hi all

Looking to stress test my chip at the above speed, thinking I might need in region of 1.35v-1.40v. Only settings ive changed so far are cpu vcore, DRAM frequency and DRAM volt. My prime95 kept crashing at a certain point, im thinking I need to change some other settings other than the 3 listed above but im not sure which might help me to get better stability. Anyone got any ideas what other settings are needed with IB for better stability at high overclock?

Also the other predicament I have is that I cant properly stress test this this as it gets too bloody hot, I tested 4.8ghz last night at 1.35v temps got to 99c after about 40 mins. Is there another quick way to test for like an hour or something?

If it get too hot, it looks like it's a barrier you've hit. Unless you can increase the cooling I would probably call it a day. I wouldn't really be comfortable above 90c

with IB do you need to change any settings other than cpu vcore? ive read that you dont but with SB there was loads other settings to change.

I believe the PLL can have an effect on the temperatures but i'm fairly new to the IB side of things so not sure on specifics.

nah crooksy's first instinct is correct. you are hitting a temp limit.

Any other settings wont help your cause, unless you haven't fixed your Load line calibration yet?

Don't feel bad. The max I could bench my 3770k at during CineBench was 4.8ghz
9.52 score! ( 85C )
