CPU over locking help

Ah very nice. The only thing I noticed he did different in the video was set the Turbo power and core current to 250 each. Unless I missed something.

So I'll set the clock back to 3.4Ghz and try with the cores at 4.5Ghz.

Will let you know how it goes later the evening

Right, so I've been doing a bit of testing at 4.5Ghz.
I have the clock set at 3.4Ghz and each core turbo set to 4.5Ghz.

Crashed after testing at 1.175V and 1.185V.
Been testing it on 1.2V now for about 20 mins with no probs.

Temps are at around 65degrees on cinebench and max 90 degrees for Prime95.

How is this sounding?

Nice.

Could go higher (1.3-1.35v) with a better cooler. But no real need to, at 4.5GHz already, unless you get the itch.

ok, so it crashed at 1.175v, 1.185v and at 1.2v

So I think i've got it running steadily on 1.225v.
Temps are maxing at 97 degrees on Prime95 and around 67 degrees on cinebench.

Cinebench is now 67C with 1.225v whereas earlier it was 75C at 1.2v? Is the room a lot colder now or something?

If 97C on Prime is accurate then you should stop using Prime with the cooler you have. Play it safe. Use less tortuous stress/benches and use your computer normally, game etc see how it goes.

the 75 was a typo.... i do apologise. 65ish is correct for cinebench.

have you cleaned the dust out of the heatsink and redone the thermal paste?

Uhh..... no? I mean I've given the computer a clean out a few times, couple months ago was the last. I didn't give the heat sink any special attention though.. and I've never redone the thermal paste.

Should I?

Is it the Intel stock cooler?

If i was you i'd get to whatever speed/volts you hit 70c at after 30 mins on a stress program and leave it there. Its cold this time of year, need to take into account when it warms up again.

If temps are good at 4.2ghz but not so at 4.4ghz its really not worth the hassle in my books.

No, it's an aftermarket one. It's the one in my basket in original post.

Hmm. So you're kinda saying the opposite of what Danny said in terms of the stress testing.

Ah, my bad, missed that. In that case agreed you may well squeeze more out of it if you take it off, thoroughly clean the heatsink (you can rinse it in liquid, without fan obviously), and replace paste.

No, he's saying exactly what I said (to aim for 70-75C). Prime is an exception.

But he said to stress test it for 30 mins. Cinebench only tests for about 1 min.

Cinebench is a fast bench so it's useful for a preliminary feel of an overclock. i.e. If it keeps passing Cinebench, keep increasing the overclock. Once it fails, dial it back 0.1GHz, and test with other stuff. Prime if you want. Asus Realbench is good.
