Okay, I know this will sound like an incredibly stupid question, and I'm sure the answer is obvious... But I was just wondering, if a motherboard that takes PC3200 RAM will accept PC100 Ram? Please don't bash me if you think this is a stupid question.

No it won't.
PC100 is differant! it has two keyways so will not physically fit anyway.

Your XP2.8+ CPU has a front side bus of 333 so you need to buy PC2700 DDR333 or higher, so PC3200 DDR400 is also fine.

Thanks! I looked it up after I posted and found that out myself. Heh, now I feel completely stupid! I was just wondering because I have like a 1/2GB worth of 128 sticks of PC100 ram laying around from my old computers! And I don't know wtf is wrong with my old one... It won't even turn on now... What happened with it has to be one of the weirdest things I've seen happen to a computer first-hand.

Anyway, thanks for the help pap!
 
Yeah older PC100/133 RAM is incompatible with the new DDR266/333/400+ RAM.

I also have some old sticks totalling about 1GB which I cannot use, lol.

All donations greatly received! I've got loads of old boards with no ram lol.

I am actually still using PC100 RAM in my room's PC, lol.

I have a AthlonXP 2000+ with 266 MHz FSB. But since the RAM is crap, I have to run it at 200MHz DDR Speeds, making it basically a 1700+. But, I've overclocked the FSB to 218MHz so the RAM runs a bit faster than normal, but the CPU is still underclocked :(

It's a rare combo board (takes 2 SDR or 2 DDR Sticks), so I will eventually get a stick of DDR3200 RAM to shove in it - that way I not only get future-proof RAM, but a faster PC since both the CPU and RAM will run at 266MHz FSB giving much better performance :)
 
Gotta be the very popular ECS K7S5A motherboard?
Or the rarer Jetway V266?

Nope. An MSI KM2M-Combo-L (Combo stands for both SDR and DDR RAM Slots, and 'L' stands for integrated 10/100 Ethernet). Quite cheap it was :)
 
Dragon,

PC100 SDRAM runs at 100MHz, not 200MHz. You must have DDR to get those kinds of speeds...

Yeah, that's what I meant...I was tired while writing that.

A boost from 100 -> 266MHz will give at least a little boost in this old PC, not to mention a faster base CPU Speed to boot!
