I just finished a build with these parts:
Antec P150
ASUS P5B-E Plus (965e chipset)
Conroe E6600
Corsair PC6400C4 RAM, 2 GB
WD3200KS SATA hard drive
Plextor 760 SATA DVD burner
eVGA 8800 GTS
X-Fi Xtreme Gamer
(Except at the moment it's an IDE hard drive, as the SATA one was DOA.)
When I check CPU-Z, it tells me that the Corsair's SPD timings are 4-4-4-12, which is also printed on the side of the DIMMs.
But when I in the BIOS enable 'use SPD timings', the RAM runs with these settings: 5-5-5-18.
If I disable 'use SPD timings' - thus getting the chance to choose them myself - and I put in 4-4-4-12, the system boots up fine, but the few benchmarks I've tried to run (3dMark and Aquamark) all terminate prematurely with failure messages.
This X-bit labs review has the following text:
1: What is the 'EPP section'?
2: Is this only supposed to work with the nForce 500 chipset?
3: How do I enable the 'Enhanced Performance Profile'?

This X-bit labs review has the following text:
To ensure that these memory modules are compatible with different mainboards, there are two work modes listed in the standard PSD field: with 4-4-4-13 timings and 533MHz frequency and 5-5-5-18 timings and 800MHz frequency. However, these numbers do not actually reflect the real capabilities of the Corsair TWIN2X2048-6400?4 memory kit. The manufacturer suggests that you should check out the potential of this solution in the EPP section. This section serves to automatically set up the memory subsystem of platforms built around any Nvidia nForce 500 chipsets based mainboards. This is where we come across the DDR2-800 mode with 4-4-4-12 timing settings that should work at 2.0V Vdimm, according to EPP.
