I have a EVGA GTX 750 Ti SC also. Boinc says it has 2409 GFLOPS peak So does mine, I just misremembered the exact number. :-) And the stderr says Kepler GPU current clockRate = 1305 MHz |

Might as well add my 2 cents worth. I've got 4 Gigabyte GTX 750Ti's, 2 in each system (Win7 & Vista). On both systems BOINC reports them as 2132 GFLOPS peak. Recently changed drivers on the Win7 to the same ones as on the Vista one to (eventually) enable a better comparison (v335.23) In my account, Application details, the APR (Average Processing Rate) for the Win7 system (been running the longest with the new hardware) 106.42 GFLOPS. Win Vista (only recently upgraded hardware) 112.90 GFLOPS. Both systems running 2 WUs at a time. As I mentioned in My new GTX 750Tis thread, the new Maxwell GPUs are much slower at processing shorties- what were around 10min WUs now take 15-18min, longer running WUs only take a minute or 2 longer. I tried running 3 at a time, and it rips through the longer running WUs, but shorties take even longer still & the end result was less throughput, not more. Hence still only crunching 2 at a time. Even though 1 GTX 750Ti does less work than even a GTX 460, the power used is so much less it's worth it for me. Even running 6 GTX 750Tis would still use less power than my previous 1*GTX460 & 1*GTX560Ti overclocked. Grant Darwin NT |

I tested the latency. It is all green. So latency is less likely to be the cause of my poor GPU load. I am using the Classic skin as well to reduce power load on CPU and my brain. ;-) Still investigating... Sleepy |

I tested the latency. Sweet. puts a whole lot of things in the clear. "Living by the wisdom of computer science doesn't sound so bad after all. And unlike most advice, it's backed up by proofs." -- Algorithms to live by: The computer science of human decisions. |
