Starting BOINC client version 6.10.58 for i686-pc-linux-gnu Processor: 4 AuthenticAMD AMD Phenom(tm) 9850 Quad-Core Processor [Family 16 Model 2 Stepping 3] OS: Linux: 2.6.36-gentoo-r5 Memory: 3.96 GB physical, 15.27 GB virtual NVIDIA GPU 0: GeForce 8500 GT (driver version unknown, CUDA version 3020, compute capability 1.1, 255MB, 29 GFLOPS peak) Note: Linux is in 32-bit mode. NVIDIA Driver Version: 260.19.29 It appears that the client is detecting the video card as a 256mb card when it is a 512mb card. Any ideas why? If you need anything further just ask.

It appears that the client is detecting the video card as a 256mb card when it is a 512mb card. Any ideas why? Is it a real physical card with that much memory on it, or is it an (embedded) on the motherboard chip, with 256MB RAM immediately on the chip and you're able to increase the memory from your computer's physical memory? The thing here is this, BOINC checks how much physical memory the GPU has. Any memory added in other ways, isn't counted. On some (HP, Dell, Compaq) systems, videocards come with 128-256MB memory by themselves, while the rest is added through the PC's physical RAM. BOINC will on these systems only see the original 128-256MB. |
