(Message 63732) Posted 16 Jun 2015 by DR4G00N Post: The sapphire card started giving memory errors & BSOD's after I replaced the fans, probably because I bent the PCB too far while taking the cooler off and cracked a solder connection. And one of my msi cards just decided it wanted to be a brick, all I did was take it out of the pcie slot and put it back in and it stopped working. :S Oh well, both will be put into the oven to see if I can bring them back for at least a little while longer.

Gigabyte GTX 780 Ti @ 1084-1111MHz core 6800MHz mem = 157 sec each I still have 1 7950 which I need to get installed in my rig.

Seems like it's saying that the 4700 is baseline and the 7850 is only 61% as fast (slower) than the 4700? Doesn't make sense. (1.000) ATI Radeon HD 4700/4800 (RV740/RV770) (0.696) AMD Radeon HD 7870/7950/7970/R9 280X series (Tahiti) (0.615) AMD Radeon HD 7850/7870 series (Pitcairn) My Dual 7850's run MUCH slower than my cpu's in terms of the "credit" I am receiving. I still don't know where to get the timing numbers you are refering to in the above posts. Which is the fastest GPU available currently? Milkyway uses Double Precision (Aka FP64) for it's calculations so if you want to compare go by that. The FP64 performance of the 7850 is only 1/16 of it's FP32 (Single Precision) performance which comes out to 110 GFlop/s. The HD 4770 does around 192 GFlop/s in FP64. Fastest gpu would probably be the GTX Titan Black (around 1700GFlop/s FP64) but the R9 280X is much cheaper and does around 1000GFlop/s FP64.

My Sapphire HD 7950 Boost used to do the same thing, it was hitting the TDP limit. If your card has a bios switch make sure it's set to position 1, that's what fixed it for me.

(Message 63375) Posted 14 Apr 2015 by DR4G00N Post: Here's the times for my main rig doing MilkyWay@Home v1.02 (opencl_amd_ati). OS: Windows 8.1 Pro x64 BOINC Version: 7.4.36 GPU Driver: 15.4 Beta CPU: Intel Xeon X5650 @ 4.1GHz GPU 1&2: MSI TF R7950's @ 1080/1250 Averaging about 27 secs each, though usually I run 2 tasks on each gpu at the same time to shave off a few seconds. 2 tasks per gpu time: 50-51 secs. Second rig, OS: Windows 8.1 Pro x64 BOINC Version: 7.4.36 GPU Driver: 14.12 WHQL CPU: Intel i7-920 @ 2.66GHz GPU: Sapphire HD 7950 OC (3L Rev.)@ 1050/1250 2 tasks per gpu time: 53 secs.
