Home Forums Hardware Mac Desktops & Notebooks VRAM doesn't show in System Profiler

I plan on upgrading to Photoshop CS5 and was checking its requirements. One of them is having a video card with 256 MB VRAM, minimum. My Mac Pro's card is NVIDIA GeForce 7300 GT, which has that spec according to MacTracker and Low End Mac. System Profiler, however, shows it with 0 MB. I'm sure that SP is wrong but why isn't it showing this correctly?

Another requirement is OpenGL support. According to that Low End Mac page, OpenCL is not supported with PCI Express. Is that the same as Open GL? If so, do I need to upgrade my video card in order to run PS CS5?

Never mind the above: I Googled OpenCL and OpenGL, which answered my question. They are not the same. The question about SP still stands, however.

Information on vram for that card is strangely hard to find where you'd expect it. Quite a few places tell you what it is that are trying to sell it however.

looks like 128mb vram on that card. That's about "industry minimum" for the time it was made so no big surprise they're not blowing any horns over it.

"How much VRAM does it have?" "If you have to ask, not enough."

Oh, just looking at that it's one of those variable cards for the newer imacs. You can probably get that upgraded if you look around.

Thanks, V1. I guess that I'll see how well Photoshop CS5 works and then decide if I want to upgrade. However, there seems to be an ambiguity about 128 MB vs. 256 MB. See these specs (click on Specifications). Specifically, it says that this card has "Memory: 256/128MB GDDR3 or / 512MB 256MB GDDR2"

A poster at the TechSurvivors forum gave me this link. Since I'm having no problems, I hesitate to mess with kexts unless I hear from one of the experts. Link to first TS thread and link to second TS thread.
