Hi there.

As of late I have been so lucky as to get some Astropulse WU's.

Thats nice, they give better credits than MultiBeam, at least when crunched on GPU's.

Sadly most of my AP WU's ends up invalid when crunched on my GPU('s).

All the CPU AP WU's and all MB WU crunched on my GPU's / CPU's are validated.

It does seem that the few WU's crunched on my R7770 got validated, but the ones crunched on my RX480 (XFX RX480 RS 8GB) are invalid.

Anybody got any ideas as to why this could be?

I'm running the latest drivers. Clocks are stock.
As said every single MB WU crunched by my GPU's get validated, so I doubt its a stability problem.
And the card is completely reliable doing anything else (gaming and so on).

It could be a driver problem, but if it is, I would suspect other experience this problem too.

I just tried deleting the learning files for the GPU AP app, to see if there could be some error in these making the crunching invalid

Oh, but it is affecting other users, https://setiathome.berkeley.edu/forum_thread.php?id=77586&postid=1873191#1873191 Some who don't even have RX 480s...or even AMD cards. It seems to affecting GPUs with drivers higher than 1912 and Newer than Tahiti. I have a couple old ATI cards running in Linux with an old driver and they work fine, the Server just refuses to send them any APs...to speak of.

My guess is another Platform has released another series of Drivers that don't agree with the Current SETI software. It's a never ending battle.

Thanks for the link. I will try to read up on what has been written there.
