Ok, well, the Geil link explains DDR1, not DDR2, which is a bit off topic,

Why would you run a 2:1 devider? That is pointless, I'm talking about a 1:2 or 3:5 devider with your memory, not running it slower than your FSB.

In that test, the Copy speed is the main difference, the read and write is a wash. Take your pick, I like a little faster bus speed.

Those tests are the same SS...lol
Silly copy and paste!

Can you please enlighten be with the difference between DDR and DDR2!

Ok, the major difference is frequency vs. timings.
In DDR1, timings are king.. but frequency isnt there. In DDR2, frequency is king, timings are the downside.

Other differences are the FBGA (Fine Ball Grid Array) of the DDR2 vs. TSOP-II of DDR1 (voltage consumption)

Then the overall Design of DDR2 vs DDR1, or 240pin vs 184pin (nothing much to compare here)

Ok, with the differences in mind, what is different about DRR2 that would allow for higher bandwidths when running your memory faster than your CPU, but DDR doesn't share those benifits?

Think about it in the classical hose idea. If you memory side of the hose can take up to 80PSI, but your CPU side has a resitor that limits it to a maximum PSI or 60, then the best you can do is 60PSI!

Think about it, why are people reaching crazy high frequencies with DDR2 but not with DDR1? Heck your DDR2 link said it all, a pair of sticks reached 1k+, and yet DDR1 is yet to reach 400. Use the sticks to their advantage, DDR2 for it's bandwith, and DDR1 for its timings.

That has to do with deviders, which is what DDR2 uses best.

You are overlooking it! Why do Cedar Mills work so much better than Prescotts? DDR2 allows for higher frequencies, which means you can obtain a higher FSB. With DDR you are limited to a 1066FSB, DDR2 can go up to 2132Mhz FSB!

What's a good free memory benchmark program? I should use Memtest for stress testing, right?

I hadn't decided what to do about the RAM speed vs. timings. I figured I'd just test it to see which gives the best performance.
