Apparently, my motherboard here supports both DDR (3200, 400 Mhz) and DDR2 (up to PC4200, 533 Mhz). I currently have 512 MB of RAM (256 MB Shared for Integrated Graphics). However, I am thinking of upgrading to 1 GB (512 x 2) or 2 GB (1 X 2). The prices for both seem to be at the same level. From what I know, DDR PC3200 chips have better latencies (2.5) compared to DDR2 PC4200 (3-4). Would I see a performance difference between the two: DDR PC3200 and DDR2 PC4200?

How did you determine that your board supports both DDR and DDR2? I'm a little doubtful that this is actually the case. It might be a good idea if you said what board you have also.

Only a select few Socket 775 (Intel) motherboards can use both DDR and DDR2.

I have the Intel 915G (LGA775). Here is the product page that states that it supports both DDR and DDR2: Intel 915G Express Chipset Overview' ">http://www.intel.com/products/chipsets/915g/

It states this:
Dual-channel DDR2 or DDR - Flexible memory support, for dual-channel DDR2 533/DDR2 400 or DDR400/DDR333 memory, in configurations of up to 4 GB RAM.

It doesn't really matter if the chipset supports DDR and DDR2, if the motherboard doesn't implement both DDR and DDR2 slots.

Theres a few chipsets that support both, and even fewer motherboards.

how can there be more chipsets than boards?

there are a # of boards that have both, u just gotta know where to look



i guess a lot to some mean 100 lol


there is prob 20-30 boards that have both


EDIT

to think about it i bet there is more then 30 boards that have both /wink.gif' border='0' style='vertical-align:middle' alt='wink.gif' />

no i was just saying i think you phrased it wrong, how could there only be a few chipsets and even fewer motherboards [with those chipsets]

Ok...obviously I was thinking the system was AMD-based. If the machine is used just for everyday stuff, you probably won't see any difference between the two. The more stress you put on the memory the more you'll see the differences between them. Beyond that, it gets a lot more complicated, but the details of it should be pretty easy to find by looking around a little.

I use the computer for folding, video/photo editing, multimedia creation, games and then the everyday stuff (more or less a bit of everything /happy.gif' border='0' style='vertical-align:middle' alt='happy.gif' />. I did a Google search for "DDR vs. DDR2" and came up with results that compared the high end memory around which doesn't really give me an idea of what to expect. I haven't found one directly comparing DDR to DDR2 using benchmarks.

Well, there's been plenty of articles about it. Some are more specialized than others and aren't going to be using benchmarks like aquamark and others that are more familiar to gamers.

I found one after some intense searching: http://www.tweaktown.com/docum...dTyp...dId=708&dPage=1' ">http://www.tweaktown.com/docum...rticle&dId=708&dPage=1
It more or less states that DDR-400 and DDR2-533 are on par, with the DDR2 module beating the DDR module by at most 1%.
Here comes another question, is it worth going to DDR2 instead of DDR when both are available at the same prices (1 GB for ~$80 and 2 GB for ~$150)?

Since prescotts are bandwidth lovers, go with DDR2

I'd vote going with this stuff:
