I've overclocked my E6550 2.33Ghz @ 3.2Ghz w/ Zalman 9700LED which i think it's a really good cooler and also doing a great job right now.
i keep having problem w/ freezing which i dont understand. i know when it freezes, it means tht my overclock is not stable. But I can't find a reason why it keeps freezing. I ran OCCT for about 3 hrs earlier and it froze again.
Here are some things that i thought it could be a reason.
2. Core Voltage
first of all, my temp is around 30' when it's idle and around 60' when im running Intel Burn Test or OCCT. is tht bad? i thought 60' on full-load is fine.
secondly, my core voltage is 1.36~1.38v. it stays changes around tht range constantly. i think it's enough. is it too much or should i give some more voltage to it?
lastly, i have 2*1GB Crucial Ballistix timed at 4-4-4-12 w/ auto voltage(around 1.8v). I ran memtest and didnt find any error. do u think i tightend the timing to much? should i loosen it to like 5-5-5-15? or like 5-5-5-18?
Please help. Thank you.
oh, and also, would changing my E6550 to E8400 be a big upgrade?
First, make sure your memory is running at its rated voltage. Post a link to the exact memory to let us see, or just use CPU-Z's SPD tab to see the settings/voltage the memory should run at.
As for the CPU, Voltage depends on the CPU, my Q6600 2 cores need a fair bit more voltage to overclock(I wish i had just the first 2 on there own chip, they clock great). So lower the clocks and slowly increase when it gets unstable, add a bit of voltage. Prime95 is a good way to test with small FFTs (blend is good to test memory/cpu)as it tends to error before out right crashing.
Your temps are fine, but its clearly unstable so you still have work to do.
