Choice of ram for PC

Hi,
I am responsible for making special effects, here is my current configuration level memory: It is therefore taken 2 memory locations.

The best would be to buy another 2 times 1024 MB; Replace the memory game 2 times 1024 MB by a set of 2 x 2048 MB Or another suggestion?

Thank you in advance for your answers!

P.S I have Windows Vista Premium 32-bit, so I could take only 3 GB, but as yet I have a graphics card with 128 MB, is there a performance gain when Windows will allocate the remaining Go to my graphics card ?

You really need more than 2GB of Ram ? If so, I advise you not to take a kit of 2 x 1GB, since in any case 32-bit Windows supports only 4 GB of addressing.

Otherwise, the performance of your graphics card will not benefit from the additional memory.

To be sure that you have not enough, is in the Windows Task Manager (with control + alt + sup +) ---> Performance tab ---> then look at the value peak, as his, how will you eat windows RAM maximum peak after your special effects.

Otherwise, I do not know if windows vista 32 bit default is set to allocate more than 2 GB to a task (to verify thus). Otherwise, 1 kit for 2 * 1 GB 1 Go that extra cost may be more suited to 32 bits.

You know what ? My problem is solved! I took the strip 2 Gb DDR2 800 Mhz 667 Mhz compatible I put on my computer and it works.
