ddr ram into sd system

Expand Post »
Uh, I'm make a big mistake lol. I've ordered 512mb of DDR Ram when my system only takes SDRAM. the RAM I have atm is 144-pin whereas the RAM i've ordered is 200pin. The question I'm asking is, will this RAM run at all in my system?

Thanks in advance,

Slade

Re: ddr ram into sd system

Nope. DDR RAM is not backwards compatible with SDRAM.

Re: ddr ram into sd system

woah wait up, I just saw something else:

Chip type

DDR CL2 SDRAM



what's that mean? Does that mean it's compatible with both? If so does the 200-pin part of it mean any incompatibility issues? Thanks again guys.

Re: ddr ram into sd system

sd ram has a different pin out, the slot is in a different place so it won't work. if it has ddr in the name, it's ddr even though it says sdram. it can be confusing

Just like tommi said, if the pinouts don't match, then you can't use it. But, to elaborate a little further, DDR is SDRAM. But, the SDRAM you're using could technically be called Single Data Rate SDRAM. Double Data Rate (DDR) is essentially twice as fast as "regular" SDRAM.

It's a variation on the same technology-- a variation that renders the two types of memory incompatible.

Re: ddr ram into sd system

does it matter if it is cl2 or cl3? Does that bring any compatibility issues about?

Re: ddr ram into sd system

CL2 is the CAS latency of the RAM, part of the RAM's timings. In short, the lower the number, the faster the RAM. Therefore CL2 > CL3.

Re: ddr ram into sd system

The CAS latency won't help you with compatibility in this instance.

It just ain't gonna work.
