Not all of my RAM is usable

2049 MB reserved. I have a ATI Radeon HD 5700 series. :)

That is a very RAM-intensive card, which I suppose is a good thing by itself.

However leaving you only 2 gb for 64 bit is a bit low, so I would consider adding at least 2gb in light of the video usage.

Or you could clean reinstall 32 bit, user choice.

Does anyone think he could afford to reduce the RAM reserved for video card? I would not unless good reason is given.

How is overall performance? Do you ever have hangs of any sort?

Hi JeffreyMartin, you can reduce the amount of memory reserved for your onboard video card.

Could someone explain my memory layout?
