I was off to clear the backlog, but I did something I advise against. Installing two different models of AMD GPU in one computer. Driver screw up. Registry corruption. Windows broken.

Hmmm, maybe the Windows AMD drivers are crankier than the Ubuntu drivers. As long as I was able to keep the number of gpu tasks the same for both different models of my Radeon video cards I was able to run different cards. (Think).

Near the end though I had exactly the same model Radeon cards so I could be mis-remembering. I no longer have any Radeon cards so I can't go back and check.

The card I got was quite old, a 6990. It had a very old style Radeon driver which probably objected strongly to Windows 11. It was ok when I moved the card to another machine, removed all the existing cards and drivers, and just put that card in with it's own drivers. I think you can only have one Radeon driver installed. You have to choose one of the right era to support all the cards you have. Newer drivers stop supporting old cards. Old drivers obviously don't support cards made after they were released.

However I think I've busted the card. One of the two GPUs in it was 102C, although it was still running! The other was 65C. I removed the existing cowl and fan and replaced it with two very powerful fans sat directly on the heatsinks, replacing the single (!) fan in the centre. This changed it to 55/90C. So I took the heatsink off the hot one and shoved more paste into it (it must have warped and been too far away). That changed it to 55/80C. It ran for 24 hours on Milkyway and now isn't recognised by any computer I plug it into. Not sure I can return it after having taken it apart and bent the heatsinks out of shape to accommodate the extra fans! I might have to sell it as spares or repairs :-(

Oops server overload, at least it didn't crash and the website still works. 150 tasks failed to upload over 24 hours, tried many times.

Have we found another bottleneck or has something blown up?

Too many users for the hardware, they have plenty of hardware for normal everyday stuff but not nearly enough for challenges that bring double the normal users.

I assume the SSDs are no longer the bottleneck. We need to upgrade something else, time for another fundraiser! I wonder if he ever got that faster network connected up? It is behaving like that - the server doesn't appear overloaded, just you can't get to it sometimes.

The pentathlon finished 5 hours ago, but I still can't get many tasks uploaded.

Hopefully we got a LOT of research done!

the admin already commented that it's a network limitation. only 300 active connections at a time.

All limitations can be overcome. What is causing this limitation? Imagine Google could only service 300 people at a time!

And did you miss me in Einstein?

try looking past your own nose and read the admin's post. he explained the limits.

And pray tell where is this post you arrogant fool(s)?
