I’m using GTX 295 (Gigabyte) for my work. Here are the specs of my PC:
MOBO: Gigabyte GA-MA790XT-UD4P
CPU: AMD Phenom II X4 965
Mem: OCZ 4GB DDR3 1066
I have a dual boot system consisting of Windows XP (SP2) and Window 7 (Ultimate).
When I run my program on XP each iteration takes ~350mS (CUDA 2.2).
But when I tried it on Windows 7 it took 800mS and every 10 (or so) times it jumped up to 2000.
I’ve tried updating the CUDA to 2.3 and Visual Studio from 2005 to 2008 (express). Nothing I do seems to get the result I get in XP.
Is there any solution for Windows 7 users?
