SRBase: GPU72 new subproject (pre-alpha)

Only way I know how to do it is by manually downclocking the GPU. If running Windows, install MSI Afterburner. It allows you to lower the GPU Core Clock, increase fan speed, etc.

This is an old 2013 laptop with AMD cataclysm Blabla monitor...not sure if that MSI software would work here.

Tested it and limited by old GPU. Thank you anyway.

It should work. Try it. Afterburner works with nvidia and amd GPUs.

Can’t see any option to change GPU usage for my AMD HD 7600M series. What I want is an option to allocate only 70-80% of the GPU to BOINC, I don’t want to underclock. Is this possible?

The app_config.xml, where to set gpu usage doesn't actually control the amount of gpu resources. It's just a way to run more than 1 WU on a gpu. Here's an app_config.xml with gpu_usage set to .5 and it will only run 1 WU at a time but it will still use all the gpu resources it can.

<app_config>
<project_max_concurrent>1</project_max_concurrent>
<app>
<name>GPU72</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

Now, I've not used this program but it says it will allow you to throttle cpu or gpu usage. It's called TThrottle by eFMr, the same folks who provide boinctasks...https://efmer.com/tthrottle/

My CPU doesn’t have an internal GPU. Back in 2013 I remember running Collatz without any lagging issues, just can’t remember if the client has an option flag to reduce GPU usage.
Will try now that software, thank you.

It doesn’t throttle my GPU, only the CPU for BOINC only. Anyway, thank you.

One last thing to try. I've never used this so I don't know how well it will work either but here's a win cmd script that will toggle the boinc client's gpu use on and off for however many seconds you want or what works.

:top

"C:\Program Files\BOINC\boinccmd" --set_gpu_mode always
timeout /T 2

"C:\Program Files\BOINC\boinccmd" --set_gpu_mode never
timeout /T 2

goto top

This will set gpu mode to always, wait 2 seconds, set gpu mode to never, wait 2 seconds and loop back around. Understand it doesn't literally run the gpu WU for 2 secs and pause it for 2 secs. All it can do send the boinc client a request to run with GPU, waits 2 secs, then sends another request to stop using gpu. I don't know what effect lag time or other variables will have but give it a try if you want. Copy and paste into a text file, name it yoyo_gpu.cmd. To run it, enter yoyo_gpu. Press <ctrl><c> to stop it. Adjust timeouts if needed.

Steve, haven’t tested the above but I really appreciate your support. Think will just run full on GPU with screen lags. Just need to know how much I can produce daily, I believe mine can process one wu each 4 hours, that will be 30k/day. NFS@Home 15k/day on CPU side.

[pinhodecarlos]

Running my GPU on it taking 1300 seconds per wu but RTX2080 is 50x faster so expect wus to take less than 30 seconds, 500 credits. Also as we move to larger ranges within the same bit depth timings will go down drastically. Example on current range 300M to 400M, 70 to 71 bits, at start of range I was doing a wu each 1500 seconds, at 360M on 1300 seconds.
