buying new ram..

[henkjan]

ok i found out that i have 1 stick of ram 512 mb DDR400 2700.
so i found out that you can have DDR400 and DDR333.
does it matter if i pud DDR333 with my DDR400?

Yes it will ... it will run slower.

Always match existing ram ... or replace it.

ok this means i have to buy 512 mb DDR400 pc 2700..
thanks alot

that doesn't make sense, AFAIK

DDR400 = PC3200
DDR333 = PC2700

unless you have DDR400 running at DDR333 speeds ?

if you have a stick of DDR333 then add a stick of DDR400 the DDR400 will set to the same speed as the DDR333

 

[henkjan]

hmm. the ram stick doesn't tell me if it is DDR400 or DDR333...
just the thing that is under the ram (where you pud the ram in...)
says with big letters DDR400.
but that doesn't mean anything does it?
EDIT: i mean under the 3 ram slots.. i don't know what it is called
it's green..

download everest, then tell us what speed the RAM is and what CPU and speed you have also what motherboard

Edit: download this instead

At least you are awake ME2001 ... well spotted.

Do you have an Athlon XP or Athlon 64?

RAM does not gain any advantage if it is asynchronous. That is - if you have a processor running at 200fsb you will want PC3200 RAM running at 400mhz at 100%. If you had a processor running at 166fsb, and stuck PC3200 with it, it would be limited to run at 333mhz. If you set the RAM in the BIOS to run at 120% you wouldn't actually benefit. However, I only think that is strictly true for NForce 2 (Athlon XP) boards. Still - always make the processor and RAM synchronous for the best results.

Anyway, I just felt like waffling. Here is your answer: *Always use the same RAM*. If you start using different speeds of RAM, or even the same spec of RAM from different manufaturers, you are just asking for instability. Generally. You MIGHT get away with it, and you won't damage the HARDWARE as such, you'll just make everything dodgier to a certain degree.

ok. here go's.
Proccessor: AMD Athlon XP @ 1916 MHz
Ram: 512 MB (1x 512 DDR-SDRAM)
what is the motherboard called? mainboard?
mainboard is K7S8X
(i just bought 512 mb PC3200 DDR400 ram)
my bro says it's allright
right now i have 512 mb PC2700 DDR400

it would have been cheaper and better if you got some PC2700 instead

I agree I've just looked up the mobo on the ASRock site and it has 3 slots, taking up to 2 GB of PC2700 DDR333.

It would have been better and cheaper to match the one already installed

nope.
pc3200 was the same price as the 2700.
and pc3200 was DDR400 and pc2700 was DDR333.
and i have DDR400.. or 300 but it doesn't matter

couldn't find a match..
