I thought the 2623-DDU came with only 256 Mb of VRAM?

Maybe it's using some system memory? Or some sort of weird cache effect? Sorry, I dunno. Just thought I'd throw a couple of ideas in there seeing as you weren't getting any replies.

Hypermemory allows the newer ATI cards to use some system memory as well as the onboard memory. So the Firegl has 256mb onboard memory and can also use 256mb of system memory for a total of 512mb. FYI, with only 256mb system memory installed in my T60p, only 256mb of memory was reported for the Firegl card so the driver was smart enough to realize it couldn't use any system memory.

256MB of it is hypermemory in work. it will allocate 256MB of main memory when it is needed, but not until then. It is a dynamic sharing thing

256MB of it is dedicated GDDR3

Thanks for the replies. Interesting. Guess I'd better bump the system RAM then.

It is the ATI HyperMemory at work, no worries.

I have an x300 that I know has 64MB of dedicated physical video memory, but 256MB gets reported because of HyperMemory.

My T60 carries w/ T1400 128MB also reported 512MB.
