ASUS R9 280x Crossfire Question's

[RoG Blackfox]

Hello,

While under load only one of my ASUS R9 280x's are working at 100%, and the other is just sitting at 300MHz Core Clock and 150MHz Memory Clock? I've run benchmarks such as ATITool, Heaven, Furmark, and various games to get the second GPU to increase... but nothing.

Make sure CFX is enabled in CCC. Also, try creating a custom profile for each benchmarking app in CCC.

What he said. In normal games it could just be that you only need that much power. What CPU do you have?

I have Crossfire Enabled in CCC, and I have profiles saved through MSI Afterburner. As for CPU it's in my description in the lower right hand corner, along with my entire system specs. Also, make note that I have my PC water-cooled as well.

The real question is why, and how can I fix getting artifacts in my $#@% games! I've run every benchmark (with stock settings which are as follows) 1070MHz Core Clock & 1600MHz Memory and have turned up with not a single artifact nor error in their diagnostics? But when I play a game artifacts appear?!?! My cards run at a cool 40c under-load?!! HELP!... Also, I have the latest CCC drivers for my cards which are 14.4 at the time of this being written.

Have you tried different PCI-E cable combos to the cards?

I have not, I would of never thought in a thousand years that it'd be the PCI-E cables, for the record the PCI-E combos is 6x X 8x PCI-E.

Note: Tried it nothing changed still got shadow artifacts in FarCry 3.

Would guess it may be one of the many problems AMD has/has had with XFire - might be a GPU itself, could run each individually and if they perform well then would be back to the XFire

I've had the cards before I cross-fired them and I've had issues with artifacting with them, and I was wondering what I could do to resolve this problem? I've throttled the voltage up on everything except the core voltage which I have at 1.2V, everything else is at max voltage. Right now as we speak I'm running fine at 1070MHz core and 1500MHz memory and everything seems fine... for now. I've read all over the internet how bad the R9 280x's have been acting in people's computers, but I unfortunately bought mine just before the storm.... Newegg "ASUS R9 280x" and you'll understand. I REALLY just want these cards to work without artifacting, RMA is out of the question as I've voided my warranty water cooling them : P

Adding the water cooling may have thrown something off, don't know, sorry 🙁 I picked up a 280X CU when they were first released and liked it, din't have any problems, then when the bit coin miners were driving the prices up, I finally gave in to a lady customer and sold it for over $100 more than what they costs brand new at their release - that's when I grabbed the 780s

Well whats done is done and there is no going back on my part with these cards, so the only thing I can do is push forward and hope AMD addresses these malfunctions with their R9 series cards. I think I've found the sweet spot, but idk I'll comment back on this thread if I come across another artifact while gaming. This experience has made me want to go with Nividia next time, along with an Intel CPU. If anyone has anymore information about these cards in crossfire, along with artifacts please comment. : )
