T60- How to resize VGA memory size?

[Nxtson]

Before I upgrade 1Gb ram for my T60, memory VGA is 256, after I upgrade, the size is 512mb. I don't know and I don't want it uses to much system ram. How can I resize?
And I bought my New T60-2623-D4U- 1.83ghz-1.5Gb ram-SXGA-80Gb Sata- 256mb Ati X1300 with 1430$, is it cheap or expensive? Thanks.

What you are referring to is the ATI HyperMemory utility that is optimizing and pre-sorting part of the system memory in addition to the on-board VRAM. To my knowledge, there is no way to size down how much system memory it uses as it seems to be proportional to the amount of total sytem RAM you have.

However, the area is still under control for general application memory, except that any graphical functions through the ATI GPU and videocard will have a slightly higher priority during renders. It really doesn't affect day-to-day operation in the sense that it doesn't "take away" any of your system memory nor does it produce a bottleneck given that the software for it is built into the ATI driver, at the kernel level of the OS, as well as recognized by the BIOS. So there should be no problems or contentions about memory management for any given loads that you could put on the system.
