Radeon Mobility HD 5850

[zswickliffe]

Hey there,

I've been searching for a couple days to try and solve this on my own with no real luck. I used to fold on my laptop with an ATI Radeon Mobility HD 5850 GPU and I just got the old laptop up and running again so I was hoping to fold on it.

Unfortunately I can't seem to get any WU to download and I'm not sure if it's because of the configuration, drivers or server outages. For reference I have a desktop with a 1080Ti folding intermittently (when the server isn't overloaded) but I just can't get this laptop to.

• - I've tried latest drivers but noticed that GPU-Z doesn't show OpenCL when I have them installed
  - I've tried old drivers and OpenCL shows back up but it still doesn't download any WUs
  - I've checked the GPU.txt file and confirmed that my GPU is listed
  - I used DDU in between driver installs
  - I've tried reinstalling F@H client

Any more advice? I just keep ggetting the below messages from F@H on repeat

I check for two prerequisites to folding, OpenCL 1.2 support and Double Precision floating point math. (F2H is all about math)

Your GPU does not support Double Precision floating point math, and so cannot Fold. Sorry.

[zswickliffe]

Ah - strange. I could have sworn that I had previously folded with it and it supported Double Precision.

Oh well! No worries, I figured it was worth trying.

Thanks for the quick answer!

[JimboPalmer]

The requirement was added as the Graphics cores became more capable, I remember folding on much weaker cards with Core_11 and Core_15, but with Core_21 and Core_22, F@H demands more from the card to do the science they need.

There are other ways for a card to fail to fold, but OpenCL 1.2 support and Double Precision floating point math are the usual sticking points.

[zswickliffe]

Got it! Makes a lot of sense. Thanks again for your help!

It has been a decade since I've used this laptop... Oh how time flies.

The desktop version of the 5850 does support DP, and can be used for folding. But the GPU folding cores use code that does to work as well on Terascale cards, so it is not as efficient.
