Not really sure if the EVGA is higher quality then V series tbh, they use CapXon caps, and inferior fans but anyway its great unit wink.gif

Those speeds sound about right. Doesn't really appear to be much difference between 290 and 290X clocks.

just bought another 290 sapphire Bf4 edition for $450 on ebay.....Gonna use it for mining.

From what i've seen these cards have a big chance to unlock let's hope I get lucky.

It increases the core voltage.

Okay! So instead of increasing by 200 in Trix, I should instead increase by 100mv, and then find the max clocks stable with that voltage. Afterwards, slowly decrease the voltage until I find at which voltage those clocks are unstable. And then maybe add like 5 to the voltage and drop the core by 10 and memory by 25 or so. Does that sound okay? And is there a little to no return in frequency overclocking beyond a certain voltage? Thank you.

Should I perform OC (Sapphire 290x) in Uber mode or Quiet mode ????.... or i will get same results on BOTH ?

Thanks

Neither one, use manual fan @65% fixed for overclocking. Do not go lower then 60% when you co, fixed fan works better the auto btw, even if you setup curve.

Good Lord!!! I flipped the BIOS switch over to the ASUS BIOS to have some benchmarking fun. It's pretty unstable, my 2nd monitor flickers sometimes, anyway. Last night I mentioned how on the stock BIOS with +100 mV my card runs with about 1.27v after vDroop and running 3Dmark I would draw about 450w from the wall. Well with the ASUS BIOS (not sure which one exactly it came flashed by the previous owner), the voltage stays locked at 1.35v and running the same 3DMark at a higher core clock I was pulling about 560w from the wall. Rock-n-roll babe!!! band.gif

Yes, but if you find the max clock at a given voltage, you probably won't be able to lower the voltage back down much without causing instability. So if you set +100, then find 1200/1500 to be stable, backing down the voltage to +75 may make those same clocks unstable again. You can try it, but you'll probably end up back where you started (+100/1200/1500, for example).

If the voltage sticks at 1.35V they may have flashed the PT1/PT3 BIOS on it, instead of a stock BIOS.

maybe it will be enough to cool 4x 290x smile.gif it is three 3x120 rads 60mm thickness biggrin.gif will run 2x D5 pumps, hope that enough... nerdsmiley.png
