More & More RAM

[dune]

Is there any PCI cards to use for RAM?
I mean like mainboard's RAM slots it has slots to put RAM onto.
If yes how Windows detect them?

No, system memory has to be accessed across a high speed bus with precise timings and separate paths for data and addresses. The PCI bus is far too slow, and both data and addresses have to share the same lines (multiplexing).

It may become feasible to get a performance boost by moving the Windows paging file to a RAM "hard-drive" when affordable ones are released:

Thanks Platypus
another question is
For a program like photoshop:
I know in photoshop you can adjust the size of RAM for photoshop to use
like 50% of system RAM.
and also you can adjust where to use for photoshop to make it's own temp files
like "C:" or etc.
which one is better :
1) use 50% of RAM & RAMDrive disk for temp files.
2) use 50% of RAM + Amount of RAM you supposed to use for RAMDrive + HDD for temp files

Photoshop uses scratch files frequently during image processing, so if you have sufficient RAM to use a ramdrive for the temp files without causing Photoshop to hit the paging file, you can speed processing considerably.

If you restrict the memory available to Photoshop too much & stuff starts being swapped out to the paging file, you're defeating the purpose of having the ramdrive.
