We have made several bug fixes and speed improvements wrapped into a new ATI GPU client (version 6.23). We strongly suggest that everyone upgrade. While current (and new cores, especially ATI GPU core version 1.22) should work with other clients, we are seeing some possible issues which the new client fixes.
As always, we suggest that one backup their machine before upgrading software, especially in case you would like to go back to the previous version. You can download the new client at
and as always, please post comments in the forum (http://foldingforum.org).
PS For those with NVIDIA GPUs, you could also consider upgrading to client version 6.23 (from https://foldingathome.org/English/DownloadWinOther ) as it also fixes some issues. However, this is less of a critical at the moment for NVIDIA than ATI.
