I purchased the eVGA 550 Ti superclocked. Official Specs:
|GPU||GTX 550 Ti|
|RAM Speed||4514Mhz (effective)|
|Memory Bandwidth||108.3 GB/s|
when I run gpusniffer.exe, it reports back this:
Testing for CUDA support...
Found 1 devices supporting CUDA.
CUDA Device # 0 properties -
CUDA device details:
Name: GeForce GTX 550 Ti Compute capability: 2.1
Total Video Memory: 729MB
CUDA driver version: 3020
CUDA Device # 0 not choosen because 765MB are required, and 729MB are present
Any idea why that might be? I followed proper intructions for adding my card to the "cuda_supported_cards.txt"..but it's not working. I suspect this is the problem.
You need to go in the bios and change the video settings to initialize the Video card first instead of the Intel Adapter on the CPU. Right now Adobe is detecting the Intel adapter as the video device instead of your card. if you have your main monitor is attached to the onboard video port then that will cause Adobe to detect the Intel adapter as the video card instead of the Nvidia card.
You likely want to download the latest driver from Nvidia's website for the 550TI as well. Select Custom when you install it and check mark the box for clean install on the next screen.
I fixed the issue with the help of ECbowen. I did not have a monitor connected to the onboard video. I did already have my "Primary video" set at PCI-16x slot.
After I played around a bit in the BIOS, I noticed a setting for changing how much RAM is allocated to the onboard video. I bumped that up from 128mb to the MAX of 480mb and that seemed to fix the issue.
After that GPUsniffer returned the proper amount of RAM, of 953MB (as Terry Green mentioned).
I was able to enable GPU accelleration in CS5. All good now!
thanks for all the help.
I have PPro CS5.5, running on a GIGBYTE HGA-H57M-USB3 MB, and it accepts GPU acceleration using a GeForce GTX 550 Ti (ASUS) when I add the name of the card to the (very short) list of supported CUDA cards in cuda_supported_cards.txt, even though it recognizes Total Video Memory as only 729MB.. I looked in the BIOS for the onboard video hack, but nothing could be changed. Maybe its CS5.5 which makes the difference.
Best wishes, Nick
I did not personally play around with the allocated RAM settings. However, I changed the onboard video settings to "Enable If No Ext PEG" (which means that the IGP is only enabled if no PCI-e x16 card is installed but is automatically disabled if a discrete GPU is found).
With that, GPUSniffer found "1024MB" on my 1GB GTX 560 I have on that system.
