What kind of RAM?

[Rh0ads]

Hello,
I know that people have different opinions on some issues, and I've heard mixed things about RAM. Which is more important, the speed or the capacity?
For example: Suppose a 256MB DDR chip costs around US$100, and a 512MB SDRAM chip costs the same.
Which chip would have the better performance?

Thanks

The speed. But uhm. That sounds like expensive DDR. I just bought myself a pc2100 256 MB Micron Crucial chip for $46 total, included s&h.

Try newegg.com, the RAM went down in price a couple days after I bought it.

Gotta love technology.

512....


while the prices are same bcoz the 512 comes in market in a short period...

if u wana use old one u can

Ok... this guys has no idea what he's talking about.

DDR RAM effectively DOUBLES your CPU's FSB. That means the computer is basically twice as fast(it has twice the bandwidth).

And 256 MB of DDR is plenty for all your common tasks and gaming. Unless you're going to do CAD applications... then more size might matters, but 256 DDR would still be faster than even 4 GB of PC133 SDRAM.

DDR RAM goes upto 533 FSB(DDR4200) over four times faster than standard SDRAM.

DDR or Double Data Rate means it can transmit a signal on the up and down current that passes into the memory older Single Data Rate only transmitted on the up current. So that is how it gives you more bandwidth. Bandwidth is not really the same as speed though not to mention that most motherboards only take one kind of RAM so don't buy DDR unless your motherboard can accept it. The two types have different pin counts so DDR RAM will not physically fit into an SDRAM slot. There is also different Latency and the speed rating but that is really just a measure of what they CAN run at not what they are running at. The actual speed of the ram is determined by the motherboard bios/cpu front side bus. So if you buy 2700 or (333Mhz) ram and only run your CPU at 266Mhz FSb then your ram will only be running at 2100 (266Mhz). Just some things to consider, its not really just a matter of speed.
