E2160 overclock failure

[umairh]

PROBLEM 1:
//////////////////////////////
Hi. When i overclock my E2160 to 3.0 Ghz @ 1.4250V . It consistently fails the prime95 stability after very little time. I think this much Volts should be enough for it. I even took it a notch higher and still the same.
Temps were hovering around 75 degrees Celcius but could possibly go higher if prime95 wouldnt fail in less than an hour. My fsb is 333 and multipler==9

DDR2 wasnt overclock and was at 667Mhz at the default voltage (increasing voltage didnt help).

I use CoreTemp for temperature monitoring.

PROBLEM 2:

Im running my E2160 overclocked to 2.7 Ghz. Prime95 thinks its stable. I think it is stable.
But the temps according to CoreTemp after I ran Prime95 for 2.5 hours were about 72 Celcius (could possible go higher if i didnt quit the test).

Im using a stock heatsink + fan.

Also am using air cooling.

Why such high temps ?



*THANKS!**

What motherboard are you using ?
Some motherboards have an issue with 333 as the fsb.
Back that voltage down. You should have no need to go as high as 1.425V


E2160@2.7Ghz and a temp of 72C is too high.
Intel list the Max temp for the cpu at 73C.

You need to upgrade the heatsink to something like the arctic freezer.

As for why the high temps, the more you increase the voltage to the cpu , the hotter it will be. Once you upgrade the cooling, start with a low overclock , 250 or so and normal voltage. Then slowly increase the fsb until the cpu has problems, then slowly increase the voltage. Keep going till you reach a point where increasing the voltage makes no difference.

FWIW, my E2140 is running 12+ hours Orthos stable at 3.2 Ghz at 1.365v. I don't think that is really out of the ordinary so your voltage seems high. I also barely reached 60C at 2.8Ghz when I was using the stock cooler (since changed over to TR Ultima-90).

Yeah, what motherboard?

I'm running Prime95 on a system I built for a friend a few weeks ago (that I didn't get around to stress testing then).

E2160 L2 stepping
IP35-E
got it running 3ghz (333x9)
cpu vcore 1.32 @ idle, vcore is 1.29 @ load (I believe).... so .03 vdroop
G.Skill DDR2 800 2.0volt 5-5-5-15
CPU:ram divider 1:1.2 (ram running at 800)
CoreTemp reporting a steady 68c on stock HSF/stock TIM (starts around 42c but has not gone above 68c)

I did run Prime95 for 2hrs at 2volt on the ram then I lowered it to 1.9 and let it run overnight; ran for nearly 4 hrs before giving an error so I restarted it this morning before I left for work back up at 2volts, Blend tests. Hopefully I get home and it's still going.

I have a similar system myself (see sig), just need to buy my cpu and gpu still and then build it (hopefully I will be ordering Friday and building as soon as it comes next week). May get an E2180 M0 from Clubit for $4 more than E2160 though. I will be shooting for 3.2ghz+ on mine, hopefully 3.4-3.6 with an Ultra120, AS5 + Yate Loon 120mm.

You may have to bump your memory voltage up, I had to do that on my friend's system above. Had hers set at 'auto' voltages; Prime95 failed within 15 minutes on 'auto'. Changed vcore to 1.325 (bios) which was like 1.29 under CPU-Z and left the other voltage settings at stock/auto for the ram, NB, etc...ran for about 20 minutes and failed. Increased vcore to 1.345 as above, ran for an hour before failing. Buddy of mine told me to then try bumping the ram voltage from 1.8v -> 2v so I did and it didn't error. (I did stop it after 2hrs to lower down to 1.9v but again that failed after nearly 4hrs so I think it will end up needing 2v.)

In any event, bumping your cpu voltage that high is not the answer I think. Bump up your ram voltage slightly (assuming you're on a good P35 board). Try 1.9v or 2v on the ram voltage and lower your vcore to 1.325 (default); if that errors than try 1.345 (or near it). My IP35-E goes up in .02v increments (1.325, 1.345, 1.365, 1.385 etc).

Lowering your vcore around those numbers will also lower your temps and probably get you back in the 60s with stock which is ok for *stock* HSF.

Besides telling us what motherboard you are using (and the model numbers of the rest of the components in your system), what are the CPU and system (inside case) idle temps? The OEM Intel CPU cooler *if properly installed* is plenty to keep the CPU cool up to at least 3GHz. If your case isn't properly ventilated, your CPU cooler won't be able to properly cool your CPU.

My E2140s required 1.425v to get to 3.2Ghz, so that sort of voltage isn't out of the ordinary, but it seems slightly high for only 3.0Ghz. Temps sound about right, for using the stock cooler. I'm using a Hyper TX2 and I get load temps of 84C.
