Something I thought was interesting, and sorry for the necro-action . . . but i think this topic best fits my post . .. https://lh6.googleusercontent.com/--c8SVI3WFHk/UWdEgybLKfI/AAAAAAAAAKI/vRkhLd8h0ho/s1152/GUIMiner.jpg
I am mining two workers on the same GPU. Apparently there are two different types of hardware, other than the CPU on this APU. One is [0.0] Beaver creek. The other is [0.1] Turks. Typically when not using my desktop I get between 100-104.9 MH/s. Supposedly this APU has "dedicated graphics", in that the GPU part of the APU has a dedicated 1GB( GPUZ shows only 512MB) of memory. Something like a daughter card usable only by the on CPU graphics . . .
Anyhow when I run with the flag -f 0, I *can* get up to ~114.9MH/s, but the screen lags something horrible, and it just seems that accepted shares slows down considerably. Yeah I do not know what that is about, but if fact, I would have to say because of over stressing the GPU. You can see in the screenshot the APU does run pretty hot, but not hot enough to bother me.
[0.0] -v -f 80 -w64 all processors set to affinity
[0.1] -v -f 60 -w64 all processors set to affinity.
Increasing the working set seems to have a detrimental effect, if anything. e.g. -w128, removing the vectors flag decreases performance by around 10% If I add another worker to either of the on APU devices, I can get an additional 4-5MH/s per, but heat does go up, and in fact the fan pretty much stays on high all the time. It seems I can only add two workers per device. Overclocking the CPU has little to no effect.
Anyway, if anyone would be so kind to quote or link this post to the post listed above I would be grateful.
Obviously the Image is edited. This has been edited only for sanitizing reasons only. e.g. do you really need to know my computer name, username, and user information for my workers . . . ?
