Some newbie pc memory questions here...

[raydeon]

thank you very much in advance for any given answers/suggestions !!

I have an ECS MB with P4 478 2.66G (it looks weird coz I dont remember there was a 2.66g ha ha ...maybe I overlocked it from 2.4g ? not sure..)

I got some newbie memory questions here and hoping someone could help me with them.

1: you guys know how some motherboards have both DDR1 and DDR2 slots right ? what is going to happen if I fill them up at the same time ? any conflict ?

2: what happens if I mix memory sticks with different Mhz value ? say I use a PC2100 with a PC3200 (since my MB has only two DDR1 slots). will it mess up my system ? or will it just simply combine them togther and work fine ?

3: is there a BIG difference between PC2100 and PC3200 ? speedwise ? performance wise ?

4: Im planning to upgrade my memories by not throwing away the old ones (which are DDR1) any good/cheap places to get them? or you experts have any good suggestions on how to upgrade them.

5: last stupid question:I have options of changing memory voltage in my bios page...what can I do with that.

THANK YOU VERY MUCH !!!

2. defaults to lowest frequency

5. you can oc your ram, also some high end ram needs higher voltage just to run correctly.
