Low PPD from entire system

post #1 of 17
Thread Starter 
Just downloaded F@H, thought I'd give it another blast, and it seems it's only taking up 84-79% GPU usage? CPU Cores are maxxed out doing a SMP though.

What AMD drivers are you using?

AMD GPUs need a full CPU core to feed it data so you will have to lower the SMP# to keep GPU utilization up.

Using 13.2 Beta 5 Drivers, GPU Usage is now around 55-63% now mad.gif F@H says my 7950 estimated PPD is 4491.33

SMP hasen't moved off the 0.00% mark yet, so no estimated PPD yet mad.gif

If you pause the SMP, what happens to the GPU utilization?

Pic below is when I paused the SMP



This was before I paused the SMP

GPU usage def went up. You'll have to lower the SMP# if you want to run the AMD card.

That SMP WU is a long one so it'll take some time to complete it, esp with the AMD GPU using so much CPU.

Any way that I can lower the usage by 50% on 1 of the cores for the GPU? I'd prefer to use all 6 cores for the SMP, whilst maintaining full GPU usage. Any work around?

To get full GPU usage it will need the CPU cycles given in the first screenshot. You could affinity lock the fahcore_16 to certain CPU cores then CPU fold on the others with maybe SMP3/4.

To get the most out of your hardware, you'll have to test out how much SMP6 does by itself and then try GPU + SMP3/4 to see the PPD you can get. This thread has a few entriy's for 1090T CPUs. The WUs like P8028 in the entries are better PPD than the one you are working on in your screenshot.

Went into Task Manager and set the affinity for 4 CPU's instead of all 6, pic below is the results, any better? or disable another core?



EDIT: What's the best way to get more PPD?

CPU already @ 4185MHz and Northbridge @ 3100MHz
GPU @ 100/1400

Estimated PPD from CPU and GPU is 8733

Update: PPD has gone up to around 9.9K to 10K is that normal for a 1055T @ 4.2GHz and a ATI 7950?
