I've been testing some Corsair PC2-5400UL memory on our ASUS P5WD2 Premium motherboard paired with the Intel 3.73 Extreme Edition processor and have been getting some pretty good results. The sweet spot of our revision 1.1 modules seems to be at timings of 5-3-3. It now seems that Corsair has revision 1.2 modules out now, and those seem to be able to run a tad better. These modules are some of the originals, so if the newer sticks run better they will be sick!
Corsair DDR2 5400UL Sandra Buffered Score:
Just shy of 8100MB/s of data transfer! Let's take a look at SuperPi 1M and Sandra 2005 SR1 unbuffered memory scores
Corsair DDR2 5400UL Sandra Unbuffered Score & Super Pi 1M:
5100MB/s unbufferd and just broke the 30 second mark on Super Pi when running the 1M benchmark. These 5400UL DDR2 modules with Micron D9 "Fat Body" IC's really do rock!
