BTW, my 2400g is %3-4 better than 2600. i wonder why.

The AMD internal GPUs ae much better and less affected by thermal/memory bandwidth constraints and if you reserve a CPU core to feed the iGPU, the output will most likely be better than just running the CPU (you'd need to keep a close eye on things to make sure that is the case).

However your system has (had?) a RTX 2070 in it, and with some configuration settings is capable of even more output than present, but if you use the iGPU for crunching you can't use those settings as they would also be applied to the iGPU and bring things to a crawl.

Best to use the iGPU to drive your monitor, then use the most aggressive settings possible for your RTX 2070, reserve a CPU core for it & let it rip.

i sold my 2070 , and R 2600.

thank you 4 ur input :)

I've been using the GPU of my 2200g. The processor itself is works fine. I have experienced some bug issues with BOINC itself, but for the most part those have worked themselves out.

Are you experiencing any problems? It looks like you have not received any GPU tasks for the 2400G. It also looks like BOINC has recognized your GPU as well. If that is the case I suspect it is an issue with uninstalling or reinstalling drivers since you removed the 2070. I don't know enough about that to help, but I'm sure someone else here would be able to walk you through.

Seti@home classic: 1,456 results, 1.613 years CPU time

It depends on what you mean by "no go"?

In general APU's crunch slower than discrete gpus. But if you feed them with 1 core and run no more than 75% of your available cpu cores the iGPU/APU will crunch faster than the cpu crunching. And it usually means higher total production for your system.

Some fairly tedious Seti benchmarking confirms that the shared memory bus slows the gpu down if all the cpus are running.

You could buy a used gtx 1060 3GB on eBay and run it side by side with the APU and pump up your output a lot. 1060's usually run under $130USD. Make sure you have at least a 240-280 watt PSU (specs call for 400 but apparently you don't need quite that much). You would need a converter to change over one of your Sata cables to the 6 pin power for the card. And you need to select a 6 pin 1060.

If that is too rich a used gtx 750Ti with no extra power plug has run nicely on my system(s).

But if you feed them with 1 core and run no more than 75% of your available cpu cores the iGPU/APU will crunch faster than the cpu crunching.

With the AMD iGPUs, maybe.
With the Intel iGPUs- unless you've got a low clock speed & low core count CPU- the CPU using all it's cores & threads will produce more work per hour than if making use of the IGPU (not to mention the huge number of Intel iGPU results that are inconclusive).
