Vista 32-bit 4x1GB vs. keeping 2x1GB

[WaxHaX0rS]

So basically when I got my system about a year ago. I just decided to get 2x1GB of RAM (I got this) at the time. Since this RAM is so damn cheap at the moment, I was thinking about just upgrading to 4GB by getting two more of these sticks. I play games, but not as much as I used to (I am excited about FarCry 2 though). I've played Crysis and UT3 on this system. I have an E6750 CPU and 8800GT GPU. Will Vista 32-bit recognize all 4GB? How will 4x1GB (vs. 2x2GB) affect the performance? Will 4GB be better than 2GB or will certain settings make it worse?
Thanks for any advices.

Notes:
According to CPU-Z (I have not played with any of these settings in the BIOS, they are just the default settings), I am running at a 5:6 (FSB😀RAM) divider and the numbers in order are 5.0/5/5/16 @ 2T. I sort of used to know what this meant in the A64 days, but I'm a bit out of the loop now.

I did the same with my rig, updated from 2x1GB to 4x1GB. 32-bit Vista isn't capable of using all of the 4GB, task manager says I've got 3325MB. So have I noticed any differences? Not really. Memory performance isn't as good with four modules than with two. Latencies and bandwidth drop a little. My PCMark Vantage score went up though, about 200 points, from 4000->4200 but that's hardly an indication of anything.

I will second what was said. Basically it will not all be recognized. Overall you won't see a real noticeable boost in performance, there should be some, but not necessarily noticeable. Unless, you are doing some very heavy multitasking or video editing (in those cases you should have a noticeable difference).
