Hello!
I just got Windows 7 Home Premium 64-bit the other day and after installing it I couldn't wait to test out the 64-bit graphics! I got on (Ohhh pretty!) and installed all the driver, did all the updates, blah blah blah. I went to the NVIDIA control panel to set my graphics card to 64-bit and the highest was 32-bit. Whats wrong?

Graphics card: NVIDIA GTS 250 512Mb. (ASUS brand) http://usa.asus.com/...WnVZ&templete=2

System:
Core i3 processor @ 2.93 Ghz
4Gb of DDR3 RAM @ 1600
850 watt power supply
ASUS P7P55 SuperComputer Motherboard
NVIDIA GTS 250 512Mb

Thank for the help!

Hi Peptobismol165
Have you tried installing the latest drivers from here http://www.nvidia.co...hql-driver.html download and save them to your desktop, uninstall the present drivers and install the new ones, hope this helps get you sorted.

You don't "set" the graphics to 64-bit. Are you sure you were not looking at "color depth"? That's different and just fine if it says 32-bit as that has to do with the number of colors, not the driver.

I personally use and recommend the 64-bit drivers from the card maker as they may be tweaked for the specific card. The drivers from NVIDIA's website are basically generic drivers for that GPU. Many card makers attempt to distinguish their cards from all the others using the same GPU and their drivers address those tweaks.

How can I tell if my system is running on 64-bit graphics? And yes I was looking at color Depth. Are those two separate things?

As I noted above,"Are you sure you were not looking at "color depth"? That's different and just fine if it says 32-bit as that has to do with the number of colors, not the driver."

Well, when you installed the driver, you would have had to select the 64-bit version. Did you?

You can check your driver version with GPU-Z - not from the folks who make CPUz, but a nice program in the same light for GPUs.

Yes I have a 64-bit driver. I downloaded it off the NVIDIA website.

The thing that worries me is when I run a DxDiag it says my current display mode is 1280 x 1024 (32-bit)(60Hz)
Shouldn't it say 1280 x 1024 (64-bit)(60Hz)?

Heres my DxDiag review.

No. That's color depth and has nothing to do with this - all my 64-bit systems also say 32-bit in that statistic. 64-bit drivers allow your hardware to communicate over a 64-bit path - which means it communicates faster and again, has nothing to do with the number of colors a graphics system can reproduce.
