Probably not worth it even if they end up doing so, as the 290X is only 1 in 8 Double Precision - you'd be way way better off going for a Single Precision Project.

7XXX were 1 in 4 DP, but the new 290X is only 1 in 8 DP.

Only 2 of the 7xxx series had 1/4 DP, the rest was mostly in the 1/16.

38xx=1/5
47xx=1/5
48xx=1/5
58xx=1/5
69xx=1/4
77xx=1/16
7790=1/14
7850=1/16
7870=1/16
7870xt=1/4
79xx=1/4
r7=1/16
r9-270=1/16
r9-280=1/4
r9-290=1/8

Thanks for the info
do you know which projects
would be good match for
the R9 290 card?

Einstein@Home uses SP, but according to some reports on their forums, the Hawaii performs slower than Tahiti. Could be an application or driver issue, but no further information about this yet.

I am using a 7970 at PrimeGrid and crunching 1,661.73 465.69 3,371.00 PPS (Sieve) v1.39 (atiPPSsieve), that is about 27.5 minutes per unit. Yours could be a bit faster as your card is an upgrade of mine.

Message 60831 - Posted: 27 Jan 2014, 18:03:35 UTC

Is there any way to get work for my R9 290X from this project? Id like to do work at least while the current team challenge is going on here.

Also, are there plans on adding support for an Intel GPU (yeah, I know, it wouldn't be fast, but I would think it wouldn't be unlike running a normal CPU app in terms of speed)

Thx for the quick reply! However, I actually have both a NVidia titan and a ATI R9 290X in the same comp and I am running on the CPU.

That depends on your R9 290X.

Is it a full-custom card or a reference card with a custom cooler? If so, look for a project that needs lots of integer performance. The cryptocurrency craze shows that this GPU is the integer king. AMD was intending to have high integer performance to speed up video encoding which requires lots of integer performance and some floating point performance, but hit the cryptocurrency market instead.

Is it a reference card with a reference cooler? Either forget about BOINC on this card and replace this card before it burns itself out or water cool the card. The inadequate cooler on this card will run the card at 95 degrees Celsius and throttle the card's performance when that threshold is tripped. AMD stated that this card was designed for high temperatures, but I don't believe it, much as my disbelief at Nvidia's claim that the GTX 480 was designed for high temperatures was validated when GTX 480s started failing according to what I remember reading in forums. If you want to keep the card, water cool it.

In all cases, monitor the GPU and the VRM temperatures. Some custom cards have been shown to cool the VRM adequately only when the fans are allowed to run at performance/uber mode but let the VRM overheat in quiet mode.

Have you tried using the APP yet?
I saw this thread at MilkyWay
http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3457#60992

And essentially they said that after some testing they got the newer cards to work over there by:
"If you run on a R9 280X*, you can download BOINC v 7.2.39 here, but you will also need AMD APP (Accelerated Parallel Processing)"

The link to download 7.2.39 is here:
https://boinc.berkeley.edu/dev/forum_thread.php?id=8378&postid=52011#52198

and the link to download the amd app stuff is here"
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/

I see you are already using the newest Boinc test version.
