Hello,

First time tried to overclock here, I was interested in some feedback of any kind, would be really grateful for some opinions or advice. Experimented with MSI Afterburner and managed to push my Palit Jetstream 970 to the following (seems pretty stable):

Core Voltage: +30
Power Limit: 111
Core Clock: +130
Memory Clock: +450

The result in Unigine Heaven are:

FPS: 58.7
Score: 1479
Min FPS: 27.5
Max FPS: 127.0

The temperature seem to be on the high side, hovering around 80 degrees Celsius most of the time I'm running the benchmark (custom fan profile: 80% fan at 80 degrees).

Default I had the following:

FPS: 53.7
Score: 1353
Min FPS: 24.9
Max FPS: 112.0

The temperature was around 77 Celsius with default fan config, which was bellow 80% (can't remember how much)

Thanks in advance!

Edit: Worked on it a bit more this morning, put fan at 75% at 75C and upped Core Clock to +150:

FPS: 60.6
Score: 1527
Min FPS: 26.6
Max FPS: 129.5

OK, figured it out with the speeds, disregard that part.

Pushed it a bit more (Core Clock +150, Memory +500) and chose a bit more aggressive fan profile and I got this:

FPS: 61.0
Score: 1536
Min FPS: 26.4
Max FPS: 128.7

Seems stable for now. Max temp was 78C with 85% fan preset to kick in when temp reaches 76C.
I am a bit worried because in most reviews the overclock they got was way lower. Is there anything else I should watch besides temperature and artifacts? Any risks?

Got voltage back to zero, left the others unchanged.

In fan profile I set the fan to 75% when temperature reaches 75C and 80% when temperature reaches 80C (liniar mode) and of course 100% when temp reaches 85C (I really hope the fan will stay at 75% most time).

After half hour of Crysis 3 on full max detail (including max AA and bloom) I could see no artifacts and there were no crashes. FPS between 40 and 60, depending on what's happening on screen. Temp stayed mostly at 75C. Opinions?
