I'm looking at some Corsair DDR3 1333 for an X38 board. There are two parts that would work, but even the "cheap" standard XMS is $300, and I'd rather not spend another $90 for the DHX version. However, Corsair's site is a bit confusing on the specs...

TWIN3X2048-1333C9: Tested at 1333 9-9-9-24, but SPD programmed at 1066 7-7-7-20.

TWIN3X2048-1333C9DHX: Also tested as 1333 9-9-9-24, and indeed SPD=1333 9-9-9-24. Includes heat sink rather than simple spreader.

Why is the first part sold as 1333 9-9-9-24, but with SPD of 1066 7-7-7-20, even though it can clearly do the correct speed and timings, and in fact is ADVERTISED at those settings?!

because it can't run at that speed on all motherboards, just like the corsair dominator dd2 modules were only gauranteed their speeds if you used it on certain 680i motherboards.

The performance of those lower priced modules at that speed isn't gauranteed in all cases. It is also just marketing, trying to get you to drop twice as much for their "prettier" modules :D

in my opinion DDR3 isn't worth it right now, you will get identical performance(for much less) running DDR2 at 900 Mhz with agressive timings.

I know, you're right. But I'm building new and the Intel X38 board will only take DDR3... :(
