TWINX 3200LLPT vs.32002P2 ASUS P4C800 Delux

[daddi0]

I built this machine ~2 years ago and bought a matched pair of 512 modules that are CMX512 3200LLPT XMS 3205v1.2 400 Mhz modules per the recommendations of the Electronics store technicians to install in the ASUS P4C800 Delux MB I bought at the same time. I recently reviewed the online Corsair pdf document that seems to imply to me that the CMX512 3200C2 is the recommended memory module. The system has preformed fairly well with the 2-3-3-6-8 settings with 2.75 volts with these memory modules. The Corsair document for the 3200LL states it has been tested extensively in the Asus SK8N and should come up with the optimal settings. Well, in a P4C800 Delux it is necessary to clock the proper settings or the system is unstable and will crash. I wanted to increase the memory to 2 gigs and would like to continue to use these two modules if possible. I recently found a matched pair of CMX512 32002P2 modules at Tiger Direct on sale and the compatibility check seemed to indicate these could be used in the ASUS P4C800 Delux. Is it possible to run the CMX512 3200LLPT memory modules with another additional pair of matched 512 modules? How much difference is there between the CMX512 3200C2 and the CMX512 3200LLPT and the 32002P2 modules? Would the system run better with the 3200C2? I have been fighting some freeze conditions recently and now it has become more frequent so these problems are all too familiar to when I first built the machine and did not have much information on the clocking and also had no knowledge of over clocking memory at the time, still don't have much. A Corsair forum thread was the only thing that saved me a bunch of hair. Any help on this would be appreciated.

It's NEVER recommended to mix modules of different part # / version #s.

The SK8N requires registered memory and the part# would not be the same. I would suggest you just replace what you have now with one Twinx2048-3200C2 or for better performance Twinx2048-3500LLPro.
