DDR3. 1600Mhz is also easier to achieve on most boards than 1066 was on DDR2, and it runs a hella lot cooler doing it.

Not to mention the memory controller on the iX series now being on-chip instead of the North Bridge... lower latencies = more better :)

Some hard numbers for you:

DDR3 1600
http://www.techpowerup.com/reviews/Cellshock/PC3_15000U_CL8_2GB/3.html
Peak Everst Read: ~10500 MB/s

my Corsair XMS3 DHX CM3X4G1600C9DHX in dual channel and clocked at 1700mhz 7-6-6-20 1T can do 11200mb/s !! on my maximus extreme!

I think my DDR2 is running at some weird divider near 1000... haven't looked lately, LOL. 1:1 must be better but I've seen tests that indicate odd dividers don't really matter, I suspect that is dependent on the chipset.

:toast: It's one of the best motherboards I've ever owned, though I've taken TWO of them out plus a graphics card with a bad PSU. :mad: One still kind of works, but part of the PCI bus is fried. The other won't post.

The third is still humming... they were all flashed with the Rampage bios. Built like tanks.

my maximus extreme is 3years 4months old and still runs like new! very tough mobo and built to last for years! I love asus ROG boards! Best gaming boards on the planet! when i had my q6600 the same day i got this mobo i OC it to 3.6ghz and it stayed like that for 2years ! now 6months ago i got a new q9650 oc to 3.8 and it is running very happy! it seems this board is hungry for my OC but i dont use watercooling only a corsair h70 which i am quiet happy with the core temps.....watercooling is expensive for me

Yea, H2O is definietly for the hobby... best bang for the buck is a good air cooler. With a decent water setup, I'd venture to guess you may only be able to get another 0.3 Ghz over air... on average, and pay dearly. Purely anectodal evidence.

Wow, I'm getting way OT here ;)

Actually that is not how actual latency works.
DDR3 has higher timing numbers than DDR2 but can have lower latency than DDR2.
DDR3 1600 @CL9 is still slightly faster than DDR2 1066@CL6.

On a 775 board like you have, the DDR2 1066 cas 5 will have lower latency than the DDR3 1600 cas 7 you quote because there is no advantage gained from use on a memory controller on the CPU. That being said, the higher frequency of the DDR3 will provide greater bandwidth. In practice, it's hard to say what would seem faster.

DDR3 has higher timing numbers than DDR2 but can have lower latency than DDR2.
DDR3 1600 @CL9 is still slightly faster than DDR2 1066@CL6.

That's correct. SDRAM latency is not a temporal measurement; it's measured in I/O bus clock cycles, and the number of those cycles per second depends on the module's data rate (e.g. the "1600" in DDR3 1600", which by the way should not be called "1600MHz"). So even though the numerical latency of DDR3 is typically higher, its actual latency as measured in nanoseconds can be lower. For example, F3-16000CL6D-4GBPIS (DDR3 2000, CAS 6) have a temporal CAS latency of 6ns, whereas KVR800D2K2 (DDR2 800, CAS 6) have a temporal CAS latency of 15ns. They have the same CAS latency number, but the DDR2's latency is actually 2.5x higher due to its lower clock rate.

I got my calculations arsed up - the DDR3 is slightly less latency, not slightly more. So it definitely would be quicker.
