E6750 @ 3.2Ghz - Need Advice

[7earitup]

Hey guys,

Just as the topic and description says, I overclocked my E6750 to 3.2Ghz from the standard 2.6Ghz by setting the FSB to 400 with a multiple of 8. I kept the memory at a 1:1 setting. I have the core voltage set to 1.25V.

What temperatures should I be seeing? What is safe with this processor? The last thing I want to do is burn it up! =)

Thanks for any help and advice!

what temps are you currently seeing using what cooler? if you were using the stock cooler and your CPU was running 80c under load at that OC i would say that wasnt surprising, but i would also recommend upgrading your cooler immediately. on the flip side if you were using a tuniq tower and you were getting 30-40c under load i would tell you to increase the OC substantially and push the vcore up more so you can get more performance out of your chip. these things are all relative you see


general rule of thumb is to aim for 30-40c idle and 50-60c under load on the higher end of things. TJmax for these chips is a lot higher but your chip will also die sooner which isnt a good thing

I am using a stock cooler. I am seeing between 50c-62c under load and it idles around 40-45c.

Wow, you have pretty good luck. I need 1.3125v to do the exact same thing. Mine runs about 30C with speedstep at idle in central illinois in this cold weather. P95 can push it up past 45C, which is no problem at all.

In warmer weather it idled around 37, which isn't bad either. If you get around what I'm getting, you should be ok.

yea your temps are fine where you are at now. if you want to try and OC it any higher i would get a new cooler, but as it is you shouldnt have any problems

I just did the same thing with a stock cooler, but I have a question...


Which temperature readout should I be looking out for, the basic CPU temperature readout or the temp at the cores?
Under load my temperature [in Everest] hits 46 after 20minutes of Orthos, but my cores are as high as 61. Most temperature probes give me just that basic temperature reading, even the Asus probe.

as long as you're keeping your cpu below 65, you should be good to go.

and you might want to read this thread. It might be old, but it's very handy for people like you who are running the E6750. GL! =)



ps: get rid of that stock cooler!

I would swap out the stock cooling but since I have no interest in gong past 3.2 it seems adequate. It seems I can drop the voltage further, I will try setting it to just under 1.3v and see how things go from there.


I am correct in the assumption that it will run cooler with lower voltage, yes?

 

[Dadofamunky]

Yeah, your temps are fine at those settings even with stock cooling. I had the same chip. 3.2 on that one is like taking candy from a baby. Getting a decent aftermarket cooler will buy you 3.6 GHz pretty easily. Beyond that it's really difficult.
