After running memtest86+ on the i7-8700 that was giving memory errors it seems I have a failed stick of memory. I bought another couple of memory kits (4 x 8GB sticks) to replace all the memory in it. The failed pair were sent back under warranty. The remaining pair were removed once the replacements arrived. That got the machine back to 32GB which it needs to run some of the Rosetta work.

I have an order in for a replacement X10SRi-F motherboard that is in the storage server. It has a failed memory socket or controller. Hopefully its not the controller because that is built into the CPU. Its been delayed. I have been told it won't arrive for a fortnight but suspect it will be much longer. In the mean time the machine still works as long as I don't use the failed socket.

Project news - Rosetta
They have been overwhelmed by the number of new users (much like Folding@home). They released an updated app along with a new app they refer to as "Rosetta for Portable devices" which has both Android and Linux (aarch64) versions.

I have all six i7-8700's running Rosetta at the moment searching for various proteins to do with Covid-19. I could run the Ryzens as well but some of the work units need 1.5GB of memory each and the Ryzens only have 16GB installed. I would have to limit them to running on half the cores or upgrade the memory.
