Whats a good Temp limit for OCing???

~~scurvy~~ · Feb 23, 2009, 01:20 PM

Currentlymy E6750 at stock speed and auto voltage reaches a maxof 60c with P95 for 30 mins.

tomorrow Iam getting the AC Freezer 7 Pro.

whats a good templimit to stop OCing??

They can take a lot more but I like to not get too far above 70C when load testing. But when hunting for an overclocking sweetspot I consider more the noise level of the cooler fan and what voltage the chip needs to achieve various stable frequencies. Too high a voltage can damage a chip even when it's not running hot, and if I can hear the fan from outside the case it gets annoying since the rest of this system is pretty low noise.

The Freezer 7 Pro seems to be essentially the same as a cooler I used on an AMD system a while back. One of the earliest to do the now almost universally used heatpipe tower design. It did quite well but was also too noisy for me with the fan on any higher speeds due to the tight fin spacing. The PWM regulation might do wonders and perhaps you're not as sensitive to noise as I am.

If it maxes at 70C or below running say 10 passes of IntelBurnTest http://www.ultimate-filez.com/files/IntelBurnTest.zip you should be fine. I select "n" for error detection, "1" for Maximum Stress and "10" for Number of Passes. You can tell if the system was stable while running it if the 2 columns of results are all identical. I use RealTemp during the InteBurnTest run to keep an eye on the temps. techPowerUp! :: Download Real Temp 3.00

I only did 5 passes in the following screenie as an example:

The results in the column with the red box should all be identical to each other.
The results in the column with the yellow box should all be identical to each other.

P95 is not enough??

Personally i don't like any CPU to gove above 50*C if i can help it....

for the intel Core series i don't like going over 50*C where as the prescot cpus i don't like seeing over 60*C, the northwoods at anything above 50*C again.

AMD same basically thing, course there are some specific cpu's i've allowed over 55*C..

I based my opinion on the E6750 in his sig, the one he also referenced in his OP, since he seems to be on a warpath for overclocking. I gave him the max for that CPU I would like to see under a stress test that probably nothing else he uses will ever match. That is unless he overvolts/overclocks by too much of which this stress test is a valid indicator. P95 is a great stability test, IntelBurnTest also is, but it will also show any weakness there may be in your rigs cooling ability for your processor. If you want to go heavily into benchmarking/overclocking that is.

Everyone is going to have differing opinions in this area but if you can keep temps at 70C or below with that processor in IntelBurnTest it should be fine under anything else you throw at it.

Depending on which test you run in P95 I would like to see nothing higher than 65C for that processor.
