overclocking i5 2500k

davegt3 · 4 Jul 2014 at 18:45

hi all i have my i5 currently over clocked using the msi oc genie. but im looking into overclocking it myself once my watercooling is finished. can any one give me a rough idea of what i should be able to achieve on full custom water cooling. and also some rough settings to start with. im hoping to get to around 4.8ghz ?

I have a msi P67A-GD53(B3) with the i5 2500k cpu am getting 4.5GHz at 1.385 core voltage with a full liquid cooled system cpu + 2 x 670gta's in loop, at the moment in the summer my temps are 35 idle and 65-70 full load with a case temp of 32c

am no expert but there are plent of them here that can help, good luck

I'm sure you can manage a lower voltage than above for 4.5 ghz ? My i7 2700k manages 4.4 ghz on 1.288v

All cpus are different...mine needs 1.38v to be stable at 4.6GHz

You need to state your machine specs really but have a look at this thread even if you dont have the same motherboard.

Mine can do 4.8ghz but it needs 1.36v I have managed 4.9ghz but its not stable at 1.4v or less.

yer ive had mine running at 4.7 on 1.4v but decided to settle at 4.5, currently running tests to see if i can get core voltage lower

Sorry I'm running

So any rough settings I can work from

i would stick the voltage up to 1.35v and see how far you can get on the multipiler

davegt3 · 12 Jul 2014 at 22:36

What are the max safe temps and voltages just so I don't melt anything lol

postmanfw · 12 Jul 2014 at 22:47

Keep under 1.4v and 80c

Pretty much this.

davegt3 · 13 Jul 2014 at 14:31

And just keep uping the multiplyer and then stress test for 45 mins or so?

Disco_P · 13 Jul 2014 at 19:41

Pretty much, 30 minutes is what I use for initial stress tests.

Also have a play with Load line calibration or vdroop to find the setting that causes the smallest decrease in voltage.

Once the test fails drop the multiplier back down and test for longer. Overnight is a good idea.

Set Vcore to 1.4v and run 5 runs of AVX enabled Intel Burn Test with ALL RAM tested.

If it passes go up a multiplier, rinse and repeat until you hit temperature limit or chip limit.

davegt3 · 17 Aug 2014 at 10:57

What's the max setting for the other voltages pll etc

Disco_P · 19 Aug 2014 at 20:40

Most people leave them to auto, and I do too.

As far as I know, adjusting them only helps with more advanced over clocking. However there are some experts out there who will tell you more.

Double post - sorry!
