XMS and SPD clarify

I post a quote from the F.A.Q. thread Archive XMS Settings Here!.

Quote:

Note, though, that in ALL CASES the Corsair part number (which contains the XMS speed grade) is programmed into the SPD as well. XMS Specification_____SPD Values XMS2700C2________JEDEC PC2700 values XMS2700LL________Custom values XMS3000__________JEDEC PC2700 values XMS3200__________JEDEC PC3200 values XMS3200C2________JEDEC PC3200 values

In XMS3200C2, for example, the part number indicates CL=2, right? And you say that the part number is programmed into the SPD. Then why the SPD for this one is "JEDEC PC3200" when JEDEC does not have CL=2 ?

JEDEC PC3200 specifies these timings:

2.5-3-3

3-3-3

3-4-4

How can I know the SPD timings?
