Help - Low PPD Amd 7950

[EXT64]

What port is your monitor plugged into, the iGPU? I have found that often when AMD GPUs are not primary and in use, they will shut off (normally a good thing). This can make them a little difficult to wake up and get working though.

I think the problem is the monitor isn't plugged into the gpu directly - will change it today.

Yes that was what I was thinking that to - gonna get a new cable and try it tonight hopefully.

Update: The problem was the monitor not being connected directly to the GPU. I'm waiting for the PPD to update but its already at 37k for the GPU.

Estimated PPD up to 85k with some overclocking.

And final update: Graphics card ran stable at ~110-115k PPD overnight with a GPU clock to 1150 MHz from 925 MHz. Memory kept stable at 1250MHz. Power limit was set at 15%. Temperature at 70 degrees celsius and fan speed at 50%.


Thank you everyone for your help.

That makes sense, I have 2 7790's clocked at 1175Mhz and Mem at 1600Mhz. They get 108k PPd between them on 14.4.
