Ram Questions!

Is 32m PC66 EDO the same thing as PC66 SDRAM?

 

[Techwhore]

NO! EDO is much MUCH slower. I think, think being the key word, that the edo ram is at 60ns or is it 70? who knows, the pc66 is at 10 ns maybe 12. Do they even make EDO DIMMS? I guess so

EDO-RAM is a much slower tech from the old times of the pentium classic. SDRAM is really the only choice. Even if you get the EDO for free.

SDram works in sync with your system clock,
making it faster than EDO, which isn't, though it was all the rage when simms were in fashion.

to put it in simple terms, they aren't even the same thing. The SDRAM are 168pins, and i think EDO rams are 72 pins? Also, if you want to use EDO ram, you have to use them pairwise, for example 2 16MB or 2 32MB. That's not the case for SDRAM

I think i might have seen EDO SDRAM somewhere and it struck me as strange. It was probably a typo. Is it the EDO memory that required it in pairs or was it the mobo chipsets... thanks

EDO does come in a 168pin configuration for DIMM slots.

It is much slower than SDRAM and (if memory serves me correctly <pun>) it runs at 5Vdc instead of the typical 3.3Vdc of SDRAM.

Choy has a good point: get the SDRAM anyway.
