George,

Patience is voluntary.

Lacking energy, focus, and lack of attention span are all symptoms of Covid-19 that haven't released their grip yet.

:(

I find myself struggling to do even a single task, sometimes.

Anyway, the Universe at Home RAC for the 3950x system has started up (OC at 4.125 M/G?hz).

So has the E@H Rac on the 3950x (it got the lonely RTX 3080 again).

I think the E@H RAC on the 3 GPU system has stopped dropping and may actually be going up again.

It would be really nice if I could get it back to 3 Million per GPU, again.

I got all 8 of my GPUs running on one board for a test.  USB risers, single lane PCI-E 2 do work, despite the grumbles from some useless people who don't know how to plug things together.

How is it processing E@H? Which one is it?

Tom M

Very well, and it was just a test, they're spread about now.  Boinc (and Folding@Home) don't need much bandwidth to the GPU.  I've never noticed any slowdown whatsoever.  The CPU single core speed is all that matters, which can be worked around by running more than one task per GPU so it can utilise more than one CPU core.

Were you vaccinated?

And I have chronic fatigue syndrome, which is basically a continuous Covid with no cure.  Medicine is not yet a science, which makes my sister irate when I say it (she works for the NHS).

My problem is I could get "tests" to work but for production, they stopped working reliably. 

If you set up that "test" rig again and it is still running without faults, problems, errors, rebooting, etc after 90 days+ I will believe you really do have a handle on it.

Yes, I was Vaccinated (3 times).  That is why the symptoms were about as severe as the last time I had a serious Flu attack.

Haven't had a serious flu attack since I started getting a flu shot every fall.

A quick Covid-19 test today was negative. Waiting for the longer/slower test results.

Every single time something went wrong was always one thing.  Power connectors.  Whatever moron designed the GPU power connectors didn't understand basic electricity.  You can't put 30 amps through those things!  Look at the flimsy little pins and compare them to a mains power plug of the same amperage!

Utter nonsense.  The vaccine doesn't work.  They might aswell inject you with water.  3 vaccines and you still catch it.  Fail, absolute fail.

People have had covid before the vaccine came out and just reported it felt like a bad cold.  The pharmaceutical companies have thoroughly ripped everyone off, and I'll have no part in it.

I haven't had even a cold since I started cold water swimming.  No idea why but it boosts your immune system.  We simply weren't designed to live in comfy warm houses.  Our bodies doze off.

No vaccine for me, no covid either, despite being in contact with people who claim to have had it.

Sounds like you are wringing as much as you can out of that cpu.  Remember you need 1-2 threads to handle the system background processes.

The gpu application is what determines how much cpu it needs to drive the gpu computation, so project relative.

If running the same gpu application, you would more than likely still only use two fully occupied threads but just run the tasks faster on the faster upgraded gpu. You current card only has 2GB of VRAM so you are limited to just one task at a time.  A newer, upgraded card would likely have more memory so you could run two tasks at a time, but that would require more cpu support which you really don't have with just 4 threads.

Think a upgrade would require both the cpu and gpu.

I like to hear that!!! i want to use every single CPU cycle possible!!! 

I found today, at a very good price, a Nvidia Quadro 4000 2GB GDDR5. Im thinking in replacing the HD7750 with that Quadro, it has almost 5x the FP64 performance and my PSU can handle it. The bottleneck calculator show the CPU and GPU will run both at 100%. Is it a good idea? Would that GPU run Einstein applications on Debian?

I think you are doing pretty much most of what you can do on those systems.

I would set the available CPU threads/cores to 75 percent to keep one core thread clear for background tasks and so you can access the system at all.

I have had good production running anything from a half a CPU core/thread to a quarter of a CPU thread per GPU task.

So it might be you could run 3 CPU tasks and one GPU task and still have a CPU thread mostly unused.

E@H GPU tasks and CPU tasks do not play well running on the same system without a lot of tinkering. It is very common to get too many CPU tasks in your cache.

The simplest way to deal with this is run a different CPU or GPU project.

Tom M

Great to hear that!!!

I will start to try some different configurations to see what happens.
