I wonder just how high those cards can go up in temp before it's considered "unsafe / bad" for the cards.
what are your guys' temps, and do you run the cards in uber mode
Tried to run 2x R290x's in Crossfire on my Asus P8P67 board and since it only has 8/4 pci-e lanes when running two cards in CF I am getting negative scaling with CF enabled
My guess is with no more CF bridge the 8/4 pci-e is killing the CF performance.
Still getting decent performance with just the 1 card- 30-35 FPS on BF4 maxed Ultra settings at 3240x1920
I have two cards. Overclocking is by Afterburner. Power slider to 150%. CCC fan slider to 100%. Uber mode BIOS setting.
My MSI will run 1100 MHz, pegged at 100% and show 93C with the fan at 50%.
My XFX card started artifacting at 1100 MHz and froze up. Same temp and fan speed.
The best clock so far on the XFX is 1075 MHZ, any higher, even 5 MHz will cause artifacting.
This is on an open air bench, fan also focused on the GPU, 850W PSU, and 24" monitor 1920 x 1200 running Heaven Benchmark DX 11, full settings except for AA.
Turns out my Seasonic 600 PSU powers my card fine. The card comes with a 2x molex to 8 pin adapter if anyone is curious. I'm currently running the following settings:
1050Mhz core
1275Mhz memory
Power Limit: 30% (no throttling at all at this setting)* anyone know exactly what this does?
Target GPU temp: 95
Max Fan Speed: 100%
While stress testing it runs at 92 degrees with 60% fan usage. Very tolerable and I am very happy.
BF4 @ 2560x1440p, Ultra, maxed out settings, 55 FPS average measured with Fraps over 10 minutes in 64 player server.
Is that with AA? Still pretty damn impressive.
so do most people here set the fan to 100% in the CCC?
I think most will. Remember though it's the MAX fan speed not a static setting. This just allows the fan to run to 100% if the GPU gets hot enough.
I just tested mine during an hour of BF4, never got above 45% fan usage and stayed rock rolid at 92 degrees.
Nope, my HIS version, that I also paid $549 for, did not come with BF4 (though apparently there is an HIS version that does come with it).Question:
Does everysingle 290x come with bf4? Mine is the gigabyte one from Amazon and it on the box it has a big picture of bf4 and even says bf4 edition. I dunno if I get the game for free though?
EDIT:
<snip>
anyone having black screen crashes with their 290x? mine is fine in games for a few minutes then display goes blank at times.
I was getting the random black screens also, just removed driver and refreshed from Device manager on windows 7. I'am still getting random crashes in BF Bad company 2, also crashed in gta 4, also crashed on new tomb raider game, not sure what the hell is going on with this card, My 580gtx ran everything perfectly fine with zero crashes. I'am getting the same feeling as with my 5870 when that came out, you would get random black screens too, took them a wile to fix the driver issue.
My current system is I7 970 @ 4.2, 18gigs of G.Skill memory , Asus x58 formula iii, 750watt power supply. Prior card before 290x was my 580gtx which i overclocked and system had zero problems for 3 years straight, since the card came out. So its the new card that seems to be the only catalyst(no pun intended) in my pc that triggered the crashing and random black screens, I dont think it s a defective card, just crappy drivers, I pay the price for getting new stuff that still running on beta drivers. But overall i like the performance, Bf 4 funny enough runs fine if you can connect to a server and does not crash, and also haven benchmarks dont crash either, pretty sure its crappy drivers.

Has there been any word on the street anywhere as to why these things are so supply constrained? Is it due to yield problems or is TSMC just maxed out making parts for the XBO, PS4, plus normal AMD and Nvidia volume? Early initial demand?

So anandtech.com bench says that the 7970 GE / 280X is faster than the GTX 770. I'm looking at both and AMD is cheaper and faster. What am I missing?
