I am running cuda3.2 on opensuse11.3/x86_64 with 2 GTX460(SLI). Nvidia’s driver is the latest one, 260.19.36.
Things go well mostly, except that two of sdk examples are not compiled properly.
Nvidia-settings reports that GTX460 has got 336 cuda cores, while deviceQuery reports each card has got
224 (number of cores). I run number crunching benchmarks, and compared results with the one on old 9800GTX+(SLI).
Considering the number of cores and clock rates, I came to guess that only 224 cuda cores are enabled on my cards.
I asked the card vendor about this, but they would not reply. (BTW, the cards do not look like a reference model.)
Has anyone of you encountered this kind of problem? Thanks for your attention.
