i5 750 overclocking

Slinkie · 14 Nov 2009 at 19:57

Hi folks,

I will be overclocking my i5 750 tomorrow. Can you offer any advice on how best to do it? What is the maximum voltage to pit through it etc

I am not new to overclocking, the last cpu I had was an i7 920. Is the any guides that give me the max tolerances of the CPU ie the max temp to hit under stress etc

I'm not really to sure what the max values are but I can tell you what my settings are:

Current clock......4.409ghz that's idle of 41 - 43 and under load goes to about 78. Only air cooled though and my family like the house way to warm for my liking.

Cpu volt is 1.46 in bios although cpuz states its using about 1.49
Ram 1.615
Vtt 1.397

I have seen people getting the same results with cpu volts as low as 1.384 if you find there setups let me know

Out of interest, what frequency and latency are you running those ripjaws at?

I just left the ram all on auto as I can not work out this gd65 board way too many options and no plain old ratios....

But I think it dumbed down a bit to 1380mhz and timing were 9-9-9-24

Gutted, I cant get mine over 4.2. Even set it to 1.48v on the core and still refuses to boot to even 4.3, Just BSODs when Windows is loading, and this is with water cooling, max temps 64 @ 4.2GHz using IBT. Tried for ages to get it higher than 4.2 but its just not having it

Unless I use the buttons on the mobo after booting lol, can get it upto about 4.6 but its unstable as hell

Funny that, I stopped at 4.2 because that was the target for the day.

Not actually tried to go further. Mainly because I run at 1.6-3.6GHz.

Although the sig says 4.2 @ 1.392V it's actually one step less than 1.392V (volts increase in CPU-Z on stressing) and NOT fully stable. It's stable for long enough though, half an hour on Prime95 Blend, but at approximately the same time an error will appear.

There are other 4.2's at 1.392V but doubt they're 12H stable.

It IS however stable on higher volts.
