Dual-X is sufficient but the fan is weak, tend to break down.

1350 - 1400 mem is slow, no? usually the memory is 1500 - 1600 range.

all my R9 280X works at 1500Mhz. Some can go to 1600Mhz.

R9 290 series run at lower memory clock?

*EDITED : I checked sites like Sapphire catalog, it does seem like R9 290 series run at lower memory clock.

that is correct. i let it stay at 1500mhz.

with GPU these days, even core clock doesn't give that much fps boost.

i'm surprised to see it perform better.

last i check, it was same amount of stream processor as 7950 but memory bus reduced from 384-bit to 256-bit

looks like the Tonga is faster than Tahiti. Wait till they come up with the 384-bit version, I think that'll be the 285X.

thanks for the summary.

based on the earlier link, the memory bandwidth is actually lesser than 7950 / R9 280.

but i also noted the memory transfer rate being 5.5 instead of 5.

i believe that's what the memory efficiency thing is about. definitely interesting.

i still have a HD 7950 with me, can't wait to pit it against the R9 285.

If I'm not mistaken, ASUS will honor the warranty.

OK i check - it's not the case.

If you're some power modder and want to mod - best you contact ASUS first.

R9 295X2 wasn't that power hogging. Hopefully the R9 3xx series does improve on power management, to something similar of nVidia's Maxwell line.

Omega Driver it is.

If you guys remember, I was at AMD Future of Compute late November and the Omega driver was announced there BUT under NDA until 9th December.

Here it is, my test drive with the driver.

tipu wan, my 14.4 when i run the Omega, it install everything EXCEPT for the driver.

had to uninstall before installing, then only the display drivers got installed.

Black screen from? I heard 14.9 has problem.

I never bothered, that's why I stick to 14.4 because if it ain't broke, don't fix it!

only have 280X.

my Diablo III become so sluggish with this driver. I also donno whether it's driver issue yet, have to roll back and see how.

here's the guide

it is possible to improve performance.

for example, when I was doing mining, there were some cards with newer BIOS that doesn't mine good enough. I had to flash it to older BIOS to make it work as what it ought to, and in some cases flash to modified BIOS to make it run even better.

I don't think one should flash firmware unless necessary. If it ain't broke, don't fix it. Cari pasal only.
