Need some help, trying to understand this...

Well, I have a new T61P 6460-6XG, with the following specs.

T7500(2.2GHz), 2GB RAM, 100GB 7200rpm HD, 15.4in 1920x1200 LCD, 256MB nVIDIA Quadro FX 570M, CDRW/DVDRW, Intel 802.11agn, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 6c Li-Ion, WinVista Ultimate 32

Now, when I do a hardware inventory test, with (SIW - System Information for Windows) it comes up and tells me that I have a 512mb graphic card?? Why is that, when it says from the lenovo hardware specs, that its a 256mb graphic card?

512MB VRAM, what is that?

Thanks alot for any help...

This is normal.

The video has 256 decidated memory, plus another 256MB from your system memory that's "shared" with the video chip.

Hi and thanks for your reply. Will this mean that it automatically reserves the extra 256mb from my memory bank or is it dynamic? I mean, do the graphic chip only utilize that extra 256mb of ram if its needed by the system?

Thanks

According to Nvidia:

"By allowing the graphics processing unit (GPU) to share the capacity and bandwidth of dedicated video memory and dynamically available system memory, TurboCache turbocharges performance and provides larger total graphics memory."

Hope it answers your question

Yes, thanks for the info... But one thing.. lets say i dont want the shared memory, is there some ways to turn that feature off? If i can utilize the 256mb elsewhere...

Thanks
