Dynamic overclock core i5-750

post #1 of 16
Thread Starter 
Hi all,

After reading on overclock.net and on http://www.tomshardware.com/reviews/...cy,2500-3.html I've tried to give mu CPU a dynamic overclock.

If I'm not mistaken I should be able to leave everything on auto with turbo boost and C-states on and still set the core clock to 140 or 150 MHz.
This doesn't work.

I've disabled spread spectrum, enabled C-states and left all the voltage options on "AUTO" but after a few minutes stress testing on core has a fatal error.

Anyone has some advice for me?

Kind regards

the 2600k will pretty much do 43 on auto. the 2500k should be able to handle it. at 43x you just need to up your turbo power to about 143w/120w/1sec (this allows the cpu to sustain the multi at 43x without backing down due to power limits, i 'think' this starts around 39x) at 44x + you will need to find your 24/7 stable with speedstep and c states disabled first. it's all about voltage thereafter.

if youu chip is good, just set voltage to 1.375-1.4v and dynamic it up to around 47-50 and check your temps. find some guides to help you. high multi should enable cpu pll overvoltage.

oh wait, you're working on a i5 750. wait for some owners of that chip to help you. sorry.

Thanks for the reaction anyway. I'll hope for some with the same setup.
No prob.

After disabling Load Line Calibration I'm getting a more stable core voltage yet still even a small OC from 133 MHz to 140 MHz isn't stable. I really can't find what I'm doing wrong. Anyone has some ideas?

You have the same board as me, use the oc genie if you're not wanting face-melting performance,

I've seen a dynamic oc before, but they can be a ***** to set up and you'd have to have a decent batch of cpu, if you update to the latest bios on the mobo you can have your turbo boost from 2-3.6, as it allows a 24x multi (can't set it manually)

The OC Genie on my board got me up to 3.8Ghz with a touch! it was 222x17.

And that gave me a nice indication of my max Base Clock.

What you getting with your OC genie?

With OC Genie it gets me up to 3.6GHz but my system uses +- 70 watts in idle en with OC Genie it shoots to +-130 watts in idle. I would really like to have the most power saving functions including turbo enabled and a base clock around 150 GHz. Now its a bottleneck for my GPU and I miss some FPS in Crysis 2.

130w i'm at 4.2 and i see 66w sometimes 100 during synthetic tests!

Download the lastest version of Control Centre for the mobo, there is some nifty green features not on the stock CC that comes with the board, i'd also recommend 100% updating the bios, the mobo is a few years old now and they've made some improvements.

Once you've got the latest bios, give it a go again and see how it goes.

I've downloaded the control center, never installed it before. I'll see what I can do with it.
My BIOS version is 1.3. The latest is 1.a.

Should I use that one?

yeah the latest one stabilised loads of things for me, it also optimised the power usage, i always have it on full power, but there is different settings in the "green power" section...

Its not the best idea overclocking with the control centre, but its good for finding min voltages on the fly,

So all in all, update bios (after backing pc up) boot to bios, set the optimised defaults, boot to os, open control centre and enable "green" mode. that should also monitor the power usage and total usage (could be handy with these energy prices) - I love all inclusive rent!
