3570k overclocking advice

TheGasMan · 5 Nov 2015 at 15:56

Hi there, I am building myself a budget gaming rig and I am looking for some advice on the overclock. I have followed an ivy bridge overclocking guide and by incrementally increasing the voltage I found a stability sweet spot of 1.27v at 4.5ghz. I have run prime95 for 12 hours and had no errors and the maximum recorded temp on real temp was 65c.

My question is do these numbers seem reasonable and would the voltage be okay to run as a 24/7 overclock or would it be better to use an offset voltage? I bought the cpu used and was told by the previous owner that the processor had been overclocked, my next question is will the processor have a reasonable lifespan running at this voltage and could the fact that it has been previously overclocked mean that the cpu has degraded in some way; if so would this effect its performance or stability?

If its relevant, here are my system specs -

Gigabyte Z68XP-UD3 Motherboard
i5 3570k
Corsair H75 Water Loop
7950 Graphics Card
Corsair TX850 Power Supply

Any help or advice would be much appreciated

The voltage is fine, I mine uses 1.236-1.260 depending on load for 4.5ghz. I would not worry about being stable on prime 95. I would normally run it for about an hour to rule out any major stability issues. Keep an eye out for whea 19 errors in the event viewer, if they appear you need more voltage.

Using your computer normally will bring up errors if the overclock is not stable, such as games crashing to desktop or plugins crashing in your browser.

I personally use offest voltage just so I can have the lower voltage and power draw when not taxing the cpu.

I would not worry about the lifespan of the cpu unless you are putting 1.4+ volts though it. The performance of the cpu does not degrade over time, it will either work or not work.

Check event log for whea errors.

I dont bother with any prime type programs anymore. As long as no crashes etc and no whea's its fine

Thanks for the advice. I've checked the event viewer for the whea errors and I seem to be fine on 1.27v. Just another quick question, how do I translate a manual voltage to an offset?

you first set the cpu voltage to normal in the cpu voltage list,this unlocks dvid(dynamic voltage) then you have a plus +/- sign to add extra or take off extra voltage from the default cpu voltage when its set to normal

you have to add a certain amount that = to 1.27v when you stress test the cpu

so could try +0.045v to start with and adjust it from there,make sure the first two numbers are 0 so not to overvolt the cpu,so +0.045v ect
