Succesfully overclocked but is it safe?

Jan3s · May 18, 2013

Hi Guys,
Today i overclocked my HIS HD7870 ICEQ and it went very well i got 10 fps boost.
Stock (1000,1200)
OC (1150,1400)
I just wanna ask that i set power limit to (+20) and Core Voltage to (1300) is this safe? and if it is can i overclock it more like (1200,1450)?
Temperature stays under 65c with these fan curve settings:

Thanks in advance!

Run furmark for a bit, If it's stable through that then it's fine.

How's it?

Overvolting is the quickest way to fry a component.

You are scaring me :S

Your voltage is a bit high but it should be ok.

81'c is not really safe, yes..it "safe", but it's not.. you know what i meant..

..you need better cooling system.

if you always upgrading your card at least once a year..then your setting is safe..but if it's not, then it's not too safe..

Ok here's the furmark picture with 95% fan usage what do you say now?

Quaddro · May 18, 2013

Better..
but HIS default fan (FirstD) is not too good..
at (almost) maximum speed, it will not survive too long..

and..at this rate, you really have a jet in your case..

Get a better cooling system..or just make your setting a little bit lower..

FANS wont last quite as long at full speed but it is ok to do. Note they will get clogged with dust pretty quick and be noisy.

Just tell me fan will not die?

Quaddro :

This is a burn-in test cause in game temperature dont go above 65c and fan stays about 75-80%

Unless the voltage goes over 1.225v you pretty much cant kill it. If you want the most overclocking headroom, set the voltage to that, then push the core and memory clocks as far as they go.

Also Furmark is not a good stress test, use a bench-marking program like Unigine.
