E7200 stable @ 2.89Ghz but can't go further.

post #1 of 35
Thread Starter 
Hi, I am a starter overclocker.

I overclocked my CPU from 2.53 to 2.89 Ghz. and it's stable now (1h test with OCCT & Prime95 for 25min).

Max temp @ this clock is 62C with stock cooler. I planned to buy something better but it no use if I cant get better results..

I already added 0.05V to make it stable, the weird thing is that friend of mine could run the same CPU and the same MB @ 3Ghz without changing the default voltage and this is not the only example, I've seen a lot of people who done the same as my friend with that CPU.
As far as I know this E7200 have a lot of potential, but not mine :\\

Whats wrong with my CPU ?


(PS my motherboard is Abit IP35-E)

Not really that great of an o/c motherboard, that being said - every processor overclocks differently. Some need no voltage to reach a certain level, while others need lots of voltage to reach the same level. .05v isn't really that much, try bumping it up more or setting it at 1.3v and see if you can run 3+ GHZ. Just remember, more voltage, more heat - so you may want to get a new cooler before attempting to o/c much further.

Yeah, I heard this a lot and I understand it, but that much difference? and why me?!

My English is not so good, by "Not really that great of an o/c motherboard" you mean that my MB not so good for OC ?

I was able to get my E7200 to 3.4GHz on stock cooler with very less volts. We can assist you better if you provide full specs of your rig and all BIOS settings.

I'll back in a minute with pics of bios, and full spec.

till then I have another question:
Any voltage value that I'm setting on the VCore actually works on 0.02-0.04~ lower than I set.
in the bios the VCore set to 1.25V, and as you can see CPUZ shows 1.23V, and under load it drops to 1.21~1.22

I should be like this or something wrong?

That's called vdroop. Its a common issue with most mobos.

Always keep the CPURAM ratio to 1:1.
1.25v seems very high vcore for 2.89Ghz, one of your RAM sticks must be causing the problem. You might want to pump more volts into the RAM sticks, 1.85 is barely above stock.
Max safe vcore limit on 45nm duos is 1.36. Anything above that with insufficient cooling will result in chip degradation.

OCCT Crash after 30 sec. (not in the monitoring minute, 30 sec after that)

higher voltage on the RAM can do damage?

Take out that one "generic RAM" dimm. Mixing RAM never works well.
Also, did you adjust the FSB strap (the RAM timings)? Your RAM probably has different timings for 266 and 333/400 MHz FSB.
