Ridata SSD - Reads up to 128MB/s - fast enough for 5 boxing?

Probably a poorly written application may assume that there is less system ram then there is. Also under XP anyway a spicfic application cannot address mre then 2G I think it is. So even if the ram is available the programe cannot use it. 64 bit systems are better I am sure. but 32 bit OS its like 2G max for an application so ....

Seems to me that if a program thinks there's less RAM available, it's less likely to use additional RAM, not more likely, so it's less likely to cause paging.

Also about the 2 GB limit. It's actually not quite as limiting as it seems (because applications get a benefit from memory in the operating system's and device drivers' address spaces) but like every limit, it causes less RAM use, so it reduces paging.

I think 64 bit Windows is more likely to page than 32 bit Windows, not less, because 64 bit Windows uses more RAM due to the fact that every integer and pointer in the operating system requires 8 bytes of RAM instead of 4. (That's what 64 bit means -- it means those objects are 64 bits wide -- 8 bytes.)

Yes, the poorly written application that is causing pagefaults when there is available ram is....WorldofWarcraft..dun dun dun

Could I ask how you're determining that there's available RAM? What number exactly on Task Manager or whatever are you using to measure that?

The reason I ask is that the memory numbers on Task Manager and Resource Manager are labeled in a very misleading way. [Edit: I should have said some of the numbers.] For example, the "Page File" number is actually the Commit Charge, not the amount of Page File used, and Commit Charge includes both physical RAM and Page File use. Etc.

Maybe it's just my dated hardware, but when I disable pagefile, I get out of memory bluescreens after booting, nevermind actually running anything. With my budget, I'll be using this machine at least another year, so no experimenting for me.

Well that shows you don't have enough RAM in the machine even to boot. This makes me very doubtful that you have any free RAM in the machine while playing WoW. Almost certainly your machine needs to page constantly no matter what you're doing because you have less RAM than the minimum used by the machine.
