Latest drivers (NVidia and ATI)
arkayn:
I will be primarily running Collatz on the 5830 so that would not really affect me there.
I might even go back to an earlier build since I have an older card.

Installed 280.26 on two of my Win 7 64 machines with GTX 295.
One produced a BSOD or hang ever couple of hours and produced Seti errors. Back to 280.26 no problems yet.
Other one produced no errors but only about 16 second runtime before it finished (Seti enhanced), with an extremely high CPU load of 100%, more than normal.
I already noticed the RAC going down on that machine.....
Did a restart, that didn't solve a thing.
Back to 208.26 and it works just fine.
Using the latest Lunatics installer.

Fred, you're getting me really confused here.

You installed 280.26, you had problems, you went back to 280.26, and then you went back to 280.26 again and now it's OK?

That sounds typical for a -9 overflow. There are a lot about.

Don't rely on RAC, it reacts far too slowly, and often in the opposite direction.
When work supply is bad, my RAC goes up, because my wingmates crunch the pending work I'm waiting for.
When work supply is good, my RAC goes down, because the buggers stuff it away in a cache instead, so my pendings go up.

When i tested the preview version of Cat 11.8, OpenCL apps consumed lots of CPU time, just like Cat 11.7, and the Nvidia 27x.xx and later drivers,

And as far as I can tell they haven't fixed the issue in the release version either

installed the latest Nvidia driver and I can confirm the memory mamangement was improvement compared to 277.
With 280.26 installed, I get this in Boinc :
19/08/2011 19:41:13 NVIDIA GPU 0: GeForce 8600 GTS (driver version unknown, CUDA version 4000, compute capability 1.1, 240MB, 96 GFLOPS peak)
so just like before.
Let's see in a few hours how it performs.
