Successfully? What OS/Catalyst ? I failed to launch such config because ATI's lack of support for Win 2003 Server OS, Claggy had bad failures for different apps when both GPUs installed... Interesting what makes your config so successful :)

- Windows 7 x64
- Catalyst 10.6
- GeForce 257.21
I have a GT240 and a HD5770.
It was a pain in the ass to get it running, since the GT240 had to be in PCIe slot 0 and the HD5770 in slot 1 - the other way round didn't work. Catalyst had to be installed first, then GeForce, ... etc. ... so trial and error.

There is an exact threshold above which is considered VHAR, and that makes shorties. I forget exactly what that threshold is, around 1.1 I think. Joe keeps that kind of information around here :D. Above that, whatever it is, they all tend to take pretty much the same short time to process.

1.12742890 or thereabouts is the maximum AR at which Gaussian searching is done, so that's still midrange. At 1.12742891 AR, Gaussians are gone along with a lot of FFTs done only for them.

It seems as if the GTX460 is doing less than the GT220 was. Floating point speed is up
while integer speed is down.
Josef W. Segur:
The "Floating Point Speed:" is merely BOINC's somewhat mangled version of the Whetstone benchmark, similarly "Integer Speed:" is a Dhrystone benchmark. They test CPU only and are run with crunching suspended, so the GPU has no effect. They cannot turn off anything non-BOINC which is running, of course, so quite a lot of variability is normal particularly on multicore CPUs. You might want to try rerunning them a few times just to see how much variation is normal for your system, in BOINC 6.10.58 the Advanced menu has the needed item.

GPU-Z 0.4.5 shows CUDA to not be available og my GTX-460, nor is
DirectCompute 4.0. It shows both ARE available on my GTS 250.
Any thoughts or suggestions will be greatly appreciated.
