Problems and Help :
problem with 7790 Bonaire
(Message 76326)
Posted 3312 days ago by ext2097
My 7790 with Catalyst 13.4 on Windows 7 64bit
2014-05-11 오후 1:53:59 | | CAL: ATI GPU 0: AMD Radeon HD 7790/R7 260X (Bonaire) (CAL version 1.4.1741, 1024MB, 966MB available, 2408 GFLOPS peak)
2014-05-11 오후 1:53:59 | | OpenCL: AMD/ATI GPU 0: AMD Radeon HD 7790/R7 260X (Bonaire) (driver version 1124.2 (VM), device version OpenCL 1.2 AMD-APP (1124.2), 1024MB, 966MB available, 2408 GFLOPS peak)
2014-05-11 오후 1:53:59 | | OpenCL CPU: Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz (OpenCL driver vendor: Advanced Micro Devices, Inc., driver version 1124.2 (sse2), device version OpenCL 1.2 AMD-APP (1124.2))
BOINC got PPS Sieve tasks normally.
And with Catalyst 13.12 and AMD APP SDK 2.9 installed
2014-05-11 오후 8:14:09 | | OpenCL: AMD/ATI GPU 0: Bonaire (driver version 1348.5 (VM), device version OpenCL 1.2 AMD-APP (1348.5), 1024MB, 1024MB available, 1204 GFLOPS peak)
2014-05-11 오후 8:14:09 | | OpenCL CPU: Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz (OpenCL driver vendor: Advanced Micro Devices, Inc., driver version 1348.5 (sse2), device version OpenCL 1.2 AMD-APP (1348.5))
No CAL found, but can get tasks by using app_info.xml.
I've also tried 13.9 and 14.4, but it seems like BOINC is not seeing CAL in Catalyst versions later than 13.4.
I wonder why the GFLOPS peak is that much differrent, 2408 GFLOPS vs 1204 GFLOPS.
And my 7790 is too slow, regardless of Catalyst version.
It took more than 4,500 seconds to finish one PPS Sieve task, which is even slower than 5770 which took about 3,600 seconds per task.
Any idea?
