Default Using memory with different timings/voltages

This is my current memory

2x1GB
ddr2 800 with 4-4-4-12 timings and 2.1V
Newegg.com - CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

I want to upgrade for more memory and I'm wondering if I really need to get something with the same timings and voltages to match what I currently have. I was thinking about:

2x2GB
ddr2 800 with 5-5-5-18 timings and 1.9V
Newegg.com - CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

Can I run those at the same time or would I have to just junk the old 2 dimms for these?

If I got something like

2x2GB
ddr2 800 with 4-4-4-12 timings and 2.1V
Newegg.com - CORSAIR XMS2 DHX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

would I be able to stick with the old dimms for 6GB total?

Thanks.

Well that will narrows down your choice a bit. XP 32bit can only use up to 3.25GB of RAM So either combo you get you could only run the 2 giving you 4GB with 3.25GB usable by the system.

Hmm that really blows. That wasn't even updated with any of the service packs? Maybe it's time to update to vista

If you want to run that much ram yes but make sure it is the 64bit version.

yes but thats $20 more expensive and not as functional (admittedly a home user generally wouldn't use the added business bits) but its also comes as a (product) red so guves money to charity.

What's the main difference between a copy of windows xp with service pack 3 and a copy of xp 64 bit ?? I've heard that finding drivers for xp64 can be a real ***** of a job. What about drivers for Vista?

Heard a lot of bad things about Vista, do many issues still linger?
