Palit GTX 1070 GAMEROCK overclocking

post #1 of 2
Thread Starter 
So i just got my new 1070 in today, and i feel i may have got a 'dud' card.
Out of the box the card boosts itself to 1897Mhz, and i added a 100Mhz core offset so it would boost itself to 2012Mhz. However, this crashed in overwatch so i dialled it back to +90, leading to a 1987Mhz boost clock.

This so far has been stable in unigine, overwatch, GTA V and Witcher 3, so im sure this is ok. I then tried upping the voltage to the max the bios allows (1.09v) with a larger core OC, but no dice, stuff was still crashing at that frequency (+100)

In addition to this, a memory Overclock of 100mhz, effectively leading to the GDDR5 going from 8Ghz to 8.2Ghz, lead to artefacts in programs like word and file explorer, so i just turned that OC off.
Going off of people getting 2.1Ghz stable on founders edition cards - is it safe to say my card is kind of a dud?
I mean, the performance itself is still amazing, but i feel that i could still get more and there is something im missing.


Just to note - temps havent exceeded 76 Celcius and i have increased power and temp limits to max in afterburner.

Help is appreciated smile.gif

You should play with the curve overclocking tool (I use it in the afterburner's latest beta): you should apply a 50Mhz overclock to the whole curve and 90-100 only to the latest frequencies (ones at 1.43 and 1.50).

Mine (Gamerock Premium) wasn't stable with 100Mhz across lower frequencies, but fine when needed - and boosts to 2125 because of that.

TLRD: It might be unstable at lower frequencies, so just use that plus 100 at the latest bit of the curve.


P.S. 2Ghz or 2.1 is not a tangible difference by the way, even if you don't get up there it doesn't matter.
