"DDR2 memory modules

Unlike the previous Pentium 4 and Pentium D design, the Core 2 technology sees a greater benefit from memory running synchronously with the Front Side Bus (FSB). This means that for the Conroe CPUs with FSB of 1066 MT/s, the ideal memory speed is PC2-4200. In some configurations, using PC2-5300 can actually decrease performance. Only when going to PC2-6400 is there a significant performance increase. While expensive DDR2 memory models with tighter timings do improve performance, the difference in real world games and applications is negligible."

... really? 677mhz could decrease performance??


"On jobs requiring large amounts of memory access, the quad-core Core 2 processors can benefit significantly [38]from using PC2-8500 memory, which runs exactly twice as fast as the FSB; this is not an officially supported configuration, but a number of motherboards offer it."
... really? >.<

Where'd you read that at? Do you have a link to the whole article? I'd like to read the rest of the set up and testing procedures...

I don't think the memory speed will make a noticable difference (either way) in every day usage. Sure benchmarks might show differences either way but you don't use benchmarks to surf the web or play games.

i still want to know that im getting my money's worth -.-

Corsair's DDR2-533 has 4-4-4-12 timings and the DDR2-667 has 5-5-5-15. Some of the tests the DDR2-667 comes out ahead. Some the DDR2-667 seems to be way behind which is wierd and I can't explain that. The Madshrimp's article does make the point that these are synthetic benchmarks and won't necessarily translate into real life performance.

I'd stick with DDR2-667 with the 1066 FSB C2D's and I would think DDR2-800 would be a logical step up for 1333 FSB C2D's (although DDR2-667 would work fine).

I've usually seen DDR2-667 cheaper than DDR2-533 (only a few bucks), and memory's so cheap now DRR2-800 isn't a whole lot more than DDR2-667.
