the kill a watt meters are only accurate for avg time , they don't pick up spikes that GPU can pull . GPU can pull like 250w but you won't see that on kill a watt meter .
My 3570@4.3 and MSI 970@1507 running Valley gets max of 300w , thats just the computer , not monitor which if you have APC , it would be included .

Has anyone tested the performance of ram clocks? Does increasing the RAM speeds actually make much difference in games or benchmarks? eg. what would 7200 > 7400 > 7600 RAM speed actually gain in FPS or benchmark / game scores? Is it worth OC RAM or just leave it at a small OC like 7200?

That is a loaded question, it depends on a lot of things , resolution , game setting , AA setting and of course the game or BM .

I'd say most BM will show a boost , just like OC gpu core .

real games, probably a smaller gain . I leave mine on 7500 even though i know i can do much more .

i run BF4 at High settings, 2xMSAA (+MFAA) and average somewhere in the 70-80 fps range. looks great and is a very fluid experience (g-sync helps).

Yes.



Overclock the card to as high as it will stably go, then decrease the settings slightly to reach 60+ frames.

First impressions are quite good, especially for the price i bought it (close to r9 290 prices, is not worthing the over 320-330Euros price tag imho).
Really silent and fast in bf4. 1340+mhz boost clocks out of the box (75% asic).
Managed to o/c it to 1600/2050 (rev. 1.1, hynix chips) in valley with +25mv but itslef downclocked to 1.2V and caused some artifacts. No matter what, i can not set it over 1.25V. As i read, this can be dealt with bios modification (any hints are appreciated, 84.04.2F.00.F1 original bios image).
1500/2000Mhz with shadowplay enabled, after 2h of bf4 is rock stable.

I do not like using furmark or kombustor etc. so what are the best tests? Just Firestrike and unigene heaven and run a few games? Are there any better ones for quickly finding what is stable?

I personally find the highest clocks that are stable in Unigene Heaven and Firestrike and then use gaming from there to determine my final stable clocks.

@nicholars i tested with all apps you mentioned and still crashed in games then i tested with occt gpu test, check 4 errors shader complexity 7 and lower my clock till there was no errors you need to test it for 900 seconds. After that test i didnt crashed 1 time in last 5 days playing games for +8 hours a day.

VRAM oc gives you better performance in benchmarks like unigine but not so much in 1080 gaming like core oc but it gives you higher lowest fps in bf4 and watch dogs atleast in my case. In unigine heaven extreme 1080, VRAM oced from 7000 to 8000 gives you more average fps 4,5 fps - for one card and 8 fps 2 cards sli enabled
