RAM or Not RAM That is the Question
 

Hope someone can enlighten me with my problem. At the moment I have 1 stick of 512 DDR SDRAM, but I have been given 3 sticks of 256m PC100 100mhz. What I would like to know is what is the best set up to have?. System spec is below.

what os ??????????? :)

Re: RAM or Not RAM That is the Question
 

AFAIK you can't mix DDR and SDR (i.e. pc100), the sticks probably won't even fit in your board.

Re: RAM or Not RAM That is the Question
 

SDram and DDR ram are not inter compatible, so its one or the other i'm afraid

missed that one , as brain death slowly comes into play :D :D :D :D

Re: RAM or Not RAM That is the Question
 

I understand i cant have both, is the existing 512 better than 767 of PC100 RAM?

Re: RAM or Not RAM That is the Question
 

probably not a lot in it tbh , why dont you try and see what happens if you swap them :)

Re: RAM or Not RAM That is the Question
 

Agreed :D

Stick them in the slot - see what happens...

You will soon discover which is better...

:whistle:

Re: RAM or Not RAM That is the Question
 

Yes, by a long way.
DDR is much faster.

Re: RAM or Not RAM That is the Question
 

good call, I just googled the board specs & it's DDR only.

the good news is that if they are good quality strips, the current price from Crucial for new ones is £99, each :eek: - so, while I doubt there is a huge demand, the OP may be able to flog them?

Re: RAM or Not RAM That is the Question
 

Sitck with the DDR. DDR actually stands for Double Data rate, so you can either look at it as 1gig RAM, at SDRam speeds, or 512m, running at twice the speed (even if it is only PC2100 speed).

Your mobo doesn't even support PC100 memory!

Chipset details here: (look under P4X400)
