RAM hardware topic...

Crucial has these two types...

DDR PC3200 ? CL=3 ? Unbuffered ? Non-parity ? 5ns ? 2.5V ? 64Meg x 64

And....

DDR PC2700 ? CL=2.5 ? Unbuffered ? Non-parity ? 6ns ? 2.5V ? 64Meg x 64

Only a couple of bucks diffrence between the PC2700 and PC3200... Tho the 2700 runs at 2.5CL, and the PC3200 runs at 5NS. What would you guys get?
Users guide says the the this MOBO will support DDR up to 266Mhz weather not you see it go that fast is a diffrent story. Just wondering will seti see much of a diffrence betweent the two?


Thanks for your help!

Neither, seti really loves low latency, high bandwidth RAM. In other words PC3200 @ CL2. If that is not in your budget go for some PC3200 @ CL2.5, the bandwidth is more important than the timings.

If you definantly want one of those two, I dont know what to tell you.

The pc2700 is all you need. It's more then enough for your m\b to handle, it's cheaper, and depending on what brand it is will o\c pretty good. I have a stick of samsung pc2700 that runs at 380Mhz.

indeed if your mobo only support pc 2100, the pc2700 cl2.5 should run at pc2100 cl2 on your system...
if you plan on upgrading your mobo in the reletivly near future then I'd say go with the pc3200, or perhaps some the super cheap(but high quality) geil pc3200 cl2, I think it's like $50 a stick for 256MB sticks.

Thanks for you help... These are going in ECS motherboards.

I got these... From Crucial.

Module Size: 128MB
Package: 184-pin DIMM
Feature: DDR PC3200
Configuration: 16Meg x 64
DIMM Type: Unbuffered
Error Checking: Non-parity
Speed: 5ns
Voltage: 2.5V
SDRAM Timings:CL=3

As Someone pointed out to me...

while PC3200 will likey run at a lower speed of 166 or 133 with better CL ratings, PC2100 that does CL2 at 133 may or may not run at 166 or 200 at all.
the 3200 RAM is rated CL3 at 200 MHz. Unless these are really weird SDRAM chips, it is pretty safe to presume that they'll do CL2 at 133. (That's because three clocks at 200 MHz is EXACTLY the same amount of time as two clocks at 133 - and so is 2.5 clocks at 166.)

Anyway... 28.00 a stick shipped isn't too bad from a known brand name company. Hoping to push them to 2CL at 166. We shall see.

Can't really see paying more for ram then I paid for the motherboard/chip/cpu fan alone... 🙂
