Folding Forum

G3WGV wrote:Thanks Joe. Most of my folding is on a new PC that I built earlier this week: Ryzen 3950X + RTX 2070 Super. I'm still getting used to how it behaves and, indeed, am happily letting F@H stress test it for me. GPU temperatures seem to be OK, stabilising out at around 65C on a long fold. I'm a bit more concerned about CPU temperatures - I have seen as high as 91C in mid fold and that feels uncomfortable. I probably need to improve my cooling strategy but in the meantime I think I will reduce the number of CPUs F@H can use from 30 down to something like 16. Any thoughts you might have on that will be appreciated.

John.

Woo! 91c is pretty toasty, what are you using for a cpu cooler? Also note, the multi-chiplet SoC like you have, has the actual cpu cores offset. One of the worlds renowned over clockers delidded teh new 3rd gen ryzen and threadripper to confirm and thus created a thermal solution that helps with as much as 10c reduction in temps.

Sorry I did not know this forum feature.

That AMD A4-7300 APU seems to be an inexpensive processor for office desktops, with integrated graphics.

Now the next question is, if you received CPU or GPU work unit, which did timeout before completion.
I guess, the GPU is also using the system's DDR3 ram, that is way slower than anything in a real graphics card.
And, GPU work units may be memory intensive.

https://en.wikipedia.org/wiki/List_of_i ... ess_memory
DDR3 is circa 10-12 GByte/s per channel, graphics cards have typically >400 GByte/s memory bandwidth.

I think, CPU work units should complete in time on that processor too.

Thank you, Darth_Peter_dualxeon, yes, I read somewhere else (the "new" forum) that there's no support for the onboard Radeon chip, and I was told to just use the CPU and put the slider to full, and it should complete in time. Also, there are some larger WU's out there. If I get something that will complete after the timeout, what should I do, just let it run anyway, or uninstall the FAHClient on that machine?

I have the single fan CoolerMaster ML120L, which should be adequate but things are probably not helped by the GPU with its big heat sink sitting just below the CPU and the radiator/fan assembly. Fitting a dual fan will be awkward but it is possible. I might have to go that route if I continue doing CPU folding because I've found that even folding with just 16 CPUs still gets too hot. The system will be used for software development mainly (certainly no gaming), so the F@H CPU loading is atypical of intended use. As GPU-based WUs are generally preferred it might be better to just stop CPU folding.

This thread is getting confusing now, with two completely unrelated topics running!

As long as it will finish before the expiration time, it will be returned and used. The timeout is only used in bonus calculations.
If you do hit the timeout with one WU, you can expect others to do the same. Note that dumping WUs is usually counter-productive and is not encouraged.

As it was told, the timeout is just for the bonus calculation. And expiration time is many days, that should be enough to finish the WU.
