i5 750 oc for a newbie

Wiry · 1 Jan 2013 at 01:29

Hi everyone,

I've owned my Intel i5 750 for about 3 years now and although it's still a brilliant chip, it's struggling to keep up with my 7970's standards... Especially seen as though my i5 is maxing out in games. So anyway to the point, basically I used to overclock my graphics cards using software like afterburner. Is there any equivalent software for my cpu? It would be far easier for me.. I've tried overclocking it through the bios before as I know this is the best way but it didn't go too well. My spec is in my sig.

anyone?

Thanks for all the help guys! I'll report back when I've tried some of your tips

I've actually got a 120mm rad with a waterblock, so I should be able to achieve a decent clock right, providing my processor will push that far.

Well it's a while since I opened this thread and thought I'd let you helpful guys know how I went on. Managed to get the i5 750 to 4.2GHz / 4200MHz (20 x 210MHz) -1.36 Vcore. Managed to get my ram etc stable after fiddling about for a while. Currently runs at about 33^celcius idle & about 55^celcius (max) in prime95 / Ibt.

How on earth have you managed to keep it at 55 degrees on full load? I've got a Megahalems and am struggling at 75!

I've been mucking around with my 750 the last couple of days. Was stuck at 3.8 at 1.375v but switched the multiplier to 21 and am now on 4.05 at 1.36v. Seeing how low I can push the volts at this frequency...

I've got a custom watercooling loop.. Only with a 120mm rad but it's quite nifty for what it is

Are the temps u getting using Intel Burn Test? or just gaming?

I've just noticed something that I previously haven't noticed.. the multipliers are different? I'm not having any issues but why would this be. The multiplier in the bios is set to x20.

Hi explosion, Welcome to the forums.

When i had my i5, i was running 4.00 GHz on a 1.36 VCore. However seen as though i had seemed to have a reasonably good chip, i could run it on a lower voltage. Start off with 1.35 and work your way up until you get a stable overclock. Just keep monitoring you temps.

You want to be adjusting the CPU voltage, the one at the top to 1.35, I doubt it will be stable but always start with a low number and keep increasing ut by a fraction if it isn't stable. If I remember to achieve 4GHz, I used a 200MHz base clock and a x20 multiplier. Let me know if you're still struggling and I'll try and make it more detailed.
