My video card system memory shows zero, is this correct?

I bought a new GTS 250 1GB DDR3 Video card and while playing youtube the video flicks a little. I notice there is system video memory is zero, dedicated 2.4GB and Availible is 1GB in the properties.

Nvidia drivers are up to date running 64bit vista.



My last video card till it died was GTX8800 and never had this problem.|||Hi

Are you having any problems playing other videos, say, direct from your pc files or problems with games ?.



What onboard memory do you have e.g. 1gb/2gb etc.?



because no matter what the video card it still eats into your onboard memory.



first check playing video files or games and look for issues if there are none then it could be youtube specific.

I don't think compatability with 64 bit system is an issue I would assume that nvidia has sorted the drivers for this by now.



Did you fully uninstall all old drivers before installation of the gts 250, if not, try deleting all graphics drivers from the pc using driver cleaner also delete drivers you may have downloaded and saved in files then go to nvidia and download a fresh set and install again, cleaning the system completely does solve a lot of issues with video card problems.|||I recommend you to use 32-bit operating system(either Windows Xp or Windows 7) as Vista 64-bit has multiple compatibility issues i.e. Vista operating system may not fully loads your video card driver|||That is correct. Because your video card has a large enough amount of dedicated memory, it does not use system memory (which would be *much* slower).
