Guys, After many years of service my GPU kicked in and I purchased a new one. With all other things remaining unchanged, my user average has dived from around 12,000 to 8,000. I would appreciate some help in understanding why. Is my new GPU a less of a performer than my old one? Or, is it due to the tasks I am being sent recently? My tasks appear unchanged each core has a task as well as the GPU and nothing sinister is appearing in the log. I have provided the old and new configurations below. Any help would be a great help. Thanks. /************************************/ OLD GPU Total credit 6,457,814 Average credit 2,622.69 Cross project credit BOINCstats.com Free-DC CPU type GenuineIntel Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz [Family 6 Model 42 Stepping 7] Number of processors 4 Coprocessors NVIDIA GeForce GTX 560 (1024MB) driver: 347.25 OpenCL: 1.1 Operating System Microsoft Windows 7 Professional x86 Edition, Service Pack 1, (06.01.7601.00) BOINC version 7.4.36 Memory 2980.09 MB Cache 256 KB Swap space 5958.48 MB Total disk space 465.66 GB Free Disk Space 357.41 GB Measured floating point speed 3786.18 million ops/sec Measured integer speed 8879.77 million ops/sec Average upload rate 31.79 KB/sec Average download rate 139.93 KB/sec Average turnaround time 1.89 days Application details Show Tasks 124 Number of times client has contacted server 119607 Last time contacted server 31 Jan 2015, 11:25:57 UTC % of time BOINC is running 95.86% While BOINC running, % of time host has an Internet connection 99.96% While BOINC running, % of time work is allowed 99.99% While BOINC running, % of time GPU work is allowed 99.99% Task duration correction factor 1 /********************************************/ NEW GPU Total credit 88,547 Average credit 5,406.07 Cross project credit BOINCstats.com Free-DC CPU type GenuineIntel Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz [Family 6 Model 42 Stepping 7] Number of processors 4 Coprocessors NVIDIA GeForce GT 740 (4095MB) driver: 347.52 OpenCL: 1.1 Operating System Microsoft Windows 7 Professional x86 Edition, Service Pack 1, (06.01.7601.00) BOINC version 7.4.36 Memory 2724.09 MB Cache 256 KB Swap space 5446.48 MB Total disk space 465.66 GB Free Disk Space 357.17 GB Measured floating point speed 3785.57 million ops/sec Measured integer speed 8868.28 million ops/sec Average upload rate 25.23 KB/sec Average download rate 146.6 KB/sec Average turnaround time 1.64 days Application details Show Tasks 429 Number of times client has contacted server 1366 Last time contacted server 14 Feb 2015, 4:45:53 UTC % of time BOINC is running 98.01% While BOINC running, % of time host has an Internet connection 99.98% While BOINC running, % of time work is allowed 100.00% While BOINC running, % of time GPU work is allowed 99.99% Task duration correction factor 1 |

Is my new GPU a less of a performer than my old one? In short, yes Sorry to say the GTX 560 is better than the GT 740. While it might have more memory, its not really using all of that while crunching. Not sure if you can run any of the optimized apps on that 740, but you can try. You might get 2 work units at a time to run but I won't try any more than that. 2 is the limit for the GTX 750s. That might help increase your stats. Zalster |

Thanks Zalster. Bad news but news I needed to hear nonetheless. |

A bit of comfort - recently there has been a sag in the credits awarded, so you might be suffering a "double whammy". (My RAC has dropped from ~96,000 to below 90,000 in the last couple o weeks, with no changes to hardware or software...)

Thanks Bob, well, I look forward to that. I went on eBay and picked up a ASUS GeForce 570 GTX for A$100 (Australian). I'll give the GT 740 to my dad. P.S. Pluto is potato fed a tad too much ammonium nitrate |
