advice on mother board

[SimonRainbo]

I didn't really know where to ask this, im still working on my new spec to buy, i was going to go with the Asus Sabretooth mobo with 16gb hyperthread ram, but i will up the ram to 24 gb eventually, would the Asus sabretooth be able to handle that or would i need to change the board.

If you click on the "help question mark" on the right hand side of "motherboard"
it should show the "Max ram".

The board will support 32GB of RAM I believe, however do note, if you're using Win7 Home Premium edition, it will limit you to 16GB no matter how much your mobo can deal with

Also note that this include VRAM too, so if you have a 3GB GTX 580, actually you can have a max of 16 between the VRAM and RAM. If you go for a better version of windows, ultimate etc, I believe they support upto 256GB.

Really?
I thought VRAM wasn't used against the OS's RAM limit.

Good point from Rakk,
the windows7 64 bit Professional & Ultimate have a maximum ram limit of 192GB.
32 bit versions have a max of 4GB.

Im pretty sure I read somewhere that (for windows 7, not sure about others) that VRAM counted against it, I may be wrong though, ill try find where I found it.

Ok just done a bit of reading, it looks like video cards do count towards the physical memory limit (in windows). The VRAM is mapped just like any system RAM to the OS. Now 64Bit systems are capable of theoretically mapping up to about 16 billion GB lol, this of course is restricted though by the OS, so in windows 7 home premium you have a max of 16GB available. This may however be a physical memory limit for RAM and windows still allocates VRAM seperatley, seeing as on a 64bit system it would be capable of doing so.

Memory limits are discussed on this page

EDIT: Disregard what I just said, just been speaking to someone who is a hardware person (unlike me) and video cards do map some memory to the OS but nto anywhere near all of it. So it may take up a very very small amount but nothing noticable really.
