which memory

[razor1]

ok i have pc100 in my pc at the mo but with prices of £80 pc133 cas2 256meg simms i just cant resist but should i wait i hear ddr is the way to go and i might b getting a new mobo and cpu in the summer.....

DDR will totally rule, but i'm going to have to upgrade my mainboard to use that, so i'm still using PC133 RAM. If you've money to burn, get the PC133 RAM for now, then get the DDR later in the year. If not, i'd reccomend you wait about 6 months.

dont think i'm stupid but....whats DDR ?

[Fandango]

DDR = Double Data Rate - basically it's RAM thats updated twice per clock cycle (for reasons I wont go into :)) so you get roughly twice the speed. Most Geforce cards apart from the very early ones use DDR RAM, and some motherboards now support it.

Athlons also take advantage of this, which is why you see some boards listed as 200mhz front side bus, when its really only 100mhz.

The new DDR boards I think he's refering to run at 133mhz/266mhz :) Got my Athlon running at this speed although I don't have the full DDR board so you could go half way and get a Via KT133a based board and run the chip at the new speed whilst still having the ability to use the older 168pin ram :)

DDR does not increase speed at all. What it increases is effective bandwidth.
A 100DDR bus (called 200 ala AMD) simply lets you transmit more information on each clock, and by sending more data at a time you increase bandwidth. But the data still only arrives every 1/100Mhz so its not 'faster'
But it is better. Just dont expect something it cant deliver, you'll get a 4-5% performance boost, not a 50% boost.

DDR motherboards are here (well 1) and from what I'v seen its not that much of an imnprovement. Better sticking with KT7a and crutal CAS2 with all the tweaks on....unless u feel the need to have three more letters infront of your RAM sticks or have money to burn and curiosity to dampen.
