You mean it's not having any effect?

 

I dunno if im on this cuda wu your talking about, but dropping my nvidia cards down to 80% does very little, the core and voltage drop but not much.

The problem I was having just needed a reboot to fix everything is back to normal now. The idea behind setting the power limit to 80% is that you  get a better PPD/Kwh. With a 80% power limit you lower the power draw on the card but it has no noticiable inpact on PPD.

Yes, the amount of cuda cores has the greatest impact on performance, slightly lowered clock speeds have much less impact.

 

I overclock and/or undervolt to achieve the highest clocks and then play with the power limit.

 

I also prefer to use the power limit to control temperatures, I have tried setting a temperature target, but found that it often doesn't work, or that it causes clock speeds to jump drastically and erratically.

I'm afraid I have no idea what limits are.

what is this limits things people speak of?!!??  i know nothing of this!!

WARNING TO NOOBS!
After the recent Nvidia driver update (456.55), that included changes to how F@H uses Nvidia CUDA cores, and a previous Widows update, Windows Task Manager no longer shows any GPU activity from any GPU resource related to F@H. It shows the GPU Temps raising but gives no indication as to why. Use HWiNFO64 or some other hardware monitor to get F@H GPU usage info.

@Den-Fi are you running your cards with a power limit ? I had mine set to 80% it doesn't seem to work with the new cuda WU ?

I reckon the problem is you are trying to run CUDA on an RX 580

Change video encode to cuda and it will show you.

After a Windows update it no longer shows CUDA.

Which update ?

Not sure when, which update, but I looked online and there have been other complaints dating back to February 2020.

[marknd59]

works for me.

Same version same build same OS I don't know why yours is different. I only update to 2004 last week so maybe that has someting to do with it.

Congrats to those that are benefiting from CUDA and congrats to the science!  While I weep for my RX5700, I'm still grateful for its service.  I'm just hoping that by the time I'll be able to get my hands on a 3080 (probably the beginning of next year), I too can join the good-a CUDA comput-a club.

You are right it should be about the science and this is good for the science but I am far more invested in the science than most. If I could I'd send you some of my extra points to keep you folding with your RX5700.

Oh, don't you worry.  This puppy will keep chugging along even if I were to get 2 3080's.  I have a nice spot on my local NAS (repurposed from my previous desktop) that would fit beautifully.

Folks - do we know if these cuda WU’s still suffer from the nvidia driver overhead? I ideally want to run cpu folding too but all the times I’ve tried on my nvidia systems the GPU PPD drop has been more than I’ve gained from the cpu folding

Looking at my CPU usage it looks like each Nvidia card still needs 1 thread.

Did you update the nvidia driver? CUDA's also gone here.

Yes I did Nvidia driver yesterday 456.55

 

My Task manager looks like this

 

 

[marknd59]

This with it showing cuda usage. Dumb question has everyone done a reboot since updating everything ? I had  somne wierd things going on until I did a reboot.

 

EDITED to add. both my folding systems are working the same both show Cuda.

 

 

[Kilrah]

I'm on the driver before yesterday's. Need to finish current WU before updating. Maybe they screwed up on the previous one and fixed it yesterday.

[Juggy]

I installed the new nVidia driver this morning and my PPD has jumped quite a bit

 

[Kilrah]

Yup, that new core does wonders

Ah beans. Every time I fold CPU and leave even 2 threads available I always get a GPU drop bigger than what I’m making up for with the cpu 

I gave up folding on my CPU and only use GPU for this very reason.

 

Well, that and the fact there have been CPU WU shortages recently.

[RollinLower]

just updated the drivers on bboth my server and my main rig. pretty curious how it does on my 2080Ti vs the dual 2080's.

i CPU fold on my AMD system but that's because the drivers don't have that kind of overhead on them that the NVIDIA ones do

 

shame of it is that my main system is getting a 3900x and those cores are going to be unused for FAH because the GPU penalty will be so high.

Yeah, it is a shame, my 2080 Super is in a 3950X system so no CPU folding on that and when there is stock of the EVGA FTW3 3080 Ultra I will remove the 2080 Super and chuck 2 in my system.

I've rebooted several times. I have to reboot after GPU driver updates or I can't access the start menu.
