Corsair XMS Cas2 not running at Cas2?!

I've left the timings in the BIOS to auto. With CPU-Z it reports CAS3. When I change to CAS to the machine won't boot. I can select CAS2 (Tcl) and that's ok. Motherboard is A8R32-MVP Deluxe. Do I need to do anything else on the memory settings to get CAS 2 to work? What settings for each should I use? (page 23 of the motherboard manual)

CL, TRAS, TRP, TRCD, TRRD, TRC, TRFC, TRWT...

ok here's a pic with CAS and TRAS manually changed (ok?)

I've checked the packaging and modules, it says TWINX2048-3200C2PT

I left the FSB clocking to 200mhz, tried cas 2 but still no luck.

oh ok. Here's a couple of pictures.

Any idea what this uninstalled device is? Any MVP owners?

ok got it working at 2-3-3-6, I dropped CPU OC back to standard, manually set voltage to 2.75 and TRAS to 6.

So I have a choice of stock CPU and faster memory, or faster CPU by 200mhz or slower memory. Which is best?
