The limit with 32-bit OSes is 4GB... 32-bit XP and 32-bit Vista should run 2GB with no issue. Test the RAM with memTest and make sure there isn't a problem with it.

This could be a RAM voltage issue. Make sure your BIOS has set the vdimm correctly. First you need to determine what the manufacturer specs are for your sticks. MOBOs frequently set the RAM voltage at a default of 1.8v but a lot of RAM requires as much as 2.2 v - if this is the case it is not uncommon for one stick to work alone but not two together.

If you need more help with this please post the specific make and model of Corsair and OCZ that you have. A link to the Newegg page will work.

OK, according to this link: http://www.ebuyer.com/product/1167 [...] ifications
your OCZ takes 2.1 v. So if your BIOS is setting it to 1.8 or 1.9 this could well be your problem.
Go into the BIOS and find the ram voltage setting - possibly called vdimm? - On my ASUS p5b deluxe it is on the same page where you set the basic system speed parameters - FSB, memory divider etc. and where you set the other voltages such as CPU, NB, etc. It shouldn't be too hard to find but if you can't we can probably look up the exact place with a little effort. Anyway, once there simply set the voltage to 2.1, save and reboot. Then shut down and put in the second stick and cross your fingers.

Not sure what voltage the Corsair takes. If this gets the OCZ working we can cross that bridge then.
