With AP tasks also working on the CPU, I use 80% CPU when I'm on the machine and 90% when I'm off it. I'm able to use such high amounts because the GPUs are standalone and I use the HD4600 iGPU for the monitor. The -tune 2 & -ocIFFT_plan, came from the readme.txt to try out and I left them there. With a lot of assistance from fellow beta testers, I came up with the following command line which seems to work for me (bold). I use EGA Precision X 4.2.1 to control fan speed. I've run AP tasks since they started and switched to v7 when it became available. 5 CPU per task with the AP tasks usually averaging 4.7k~4.8k seconds per task. With the speed of my 4700K, I'm able to allocate. card as the primary tasks with 3 x MB to take up the slack on each. I'm running 2 x EVGA GTX750Ti FTW w/ 2GB DDR5 1189 MHz Base & w/ 1268 MHz Boost Clock (factory defaults). It's not the fastest out there but it gives you a lot of computing power per watt and that is very important for me. I only crunched 4 tasks with this settings yet but it seemed to speed up crunching by about 10 minutes.
Seems stable and temperature didn't go up (max 62 degrees with fan running at 38%) so I could maybe try a little more next time. I raised clockspeed by 100 and memory clock by 200. Today I installed MSI Afterburner and made my first steps in overclocking my card. use_sleep -unroll 10 -oclFFT_plan 256 16 512 -ffa_block 12288 -ffa_block_fetch 6144Ĭrunching 2 AP7 tasks usually takes about 5000 seconds, sometimes a bit more, sometimes a bit less. I usually crunch AP on my card, 2 tasks at a time and I currently use the command line which Mike suggests for the 750Ti: When crunching I see a clock speed of 1202 Mhz. Let me start here: I own a MSI GTX750 OC Edition with 1GB DDR5 RAM.Clock speed is 1059/1137 Mhz.
Do you crunch MB or AP? How many tasks do you run at the time? What command line do you use? Do you overclock and if yes, how and how much? And overall, are you satisfied with the performance of your card? I'm interrested to hear what cards exactly you own and how you use them. I thought I start a thread for just this type of card so ppl who own this can share their experience and discuss settings, command lines, etc. The GTX750(Ti) is one of the most energy efficient cards and therefore one of the most interresting cards for crunching.
