Specs: Microsoft Windows XP Professional, 2.333 GHz / 2046 MB

im gonna add another 4GB ram. i already have 2GB ddr 800 dual ram. they are OCZ also. i scan my pc with CPUZ, the timing of my current memories are 5-5-5-15. i check the spec of this ram above. the timing is 4-4-4-15. will that have any effect? do i have to buy 5-5-5-15 memory? the voltage of my current ram is 1.8v. the one above is 2.2v. can different voltage also affect the pc performance? thanks

I don't recommend mixing RAM of different'll either have to overvolt one or undervolt the other. Either way, it's bound to cause problems.

Are you running the 64-bit version of XP (or Vista)? If not, you're wasting your time installing any more than 4GB RAM, & even with 4GB, only about 3.0-3.5GB will actually be usable.

well, thanks. but if i upgraded to 8GB, i would actually still have like 6-7GB that is being used, right? that's still better than 2Gb, even 4gb.

WinXP 32 bit is limited to 4GB gross RAM. That is what jam stated.

Mixing RAM with different voltage requirements, especially .4V difference, MAY result in a no boot situation or possibly damaged RAM.
