Just a heads up ... Have been watching my temperatures/usage patterns quite carefully and can advise the following for comparison:PRP_R148H wrote:Well, if we can't go on holiday right now, at least our GPUs can! I'll see how the SSD fares. Yes it's quite a farce what's happened to the GPU market. I managed to grab a pair of fairly (?) well priced 3070s from a store and as soon as I bought them, they raised the price $200 for the next batch. Wow.
Also thanks Joe_H for that explanation of the WU:atom business and how that affects checkpointing.
Checkpointing on my system appears to last maybe a second - GPU usage shows a slight dip of maybe 5% but temperature and clocks speeds don't change.
At the changeover of WUs my system preloads at 99% so next WU is ready to run - GPU usage drops to effectively 0 for maybe 3 seconds (occasionally possibly 10 seconds) as the client focuses on wrapping/packing/shutting down one core and spinning the next one up ... In this time the GPU gets a bigger chance to cool and drops maybe 10C (15C with the longer pause) with clocks also spinning down for a shorter while - this drop is some 30% to 50% of the difference between folding temp and ambient.
Now my kit is fast and cools well - the changeover shows that temp drops do happen is gpu not loaded but the minimal drops I am seeing on checkpointing imply it doesn't need to happen to the same extent as you have seen - the pausing that you have spotted will undoubtedly be a major factor in the spiking you have observed ... hopefully the move from a usb install to an ssd install resolved the majority of this ... Do let us know how this goes/has gone.
