K8N Neo2 with AMD 4200 X2 - Memory config.

Question

Will my AMD 4200X2 allow me to use 4 sticks of 512 MB on the K8N Neo2 motherboard?  I know that there have been issues using 4 sticks on with AMD 64 3500 chips, but I don't know if this still applys to the newer X2s.
Thanks for any info on this.

The user manual for the Neo 2 says you cannot do it because it was written before Venice and later cpus, so it is outdated in that it does not recognize that 4 identical dual sided PC3200 dimms will run at 400 and not just 333 with the newer cpus that came out after the user guide (manual) was written.
Edit- LairdD- You miss the point -- you don't have to overclock to do it, you just need identical dimms and the right cpu.
No, qyx, you missed the point, uhh... twice.   My previous post referenced the AMD [26094.pdf] doc on the subject... which you appear not to have read... not the MSI manual.
The newer >=Rev E CPUs have the same speed specs as previous ones on fully populated ranks in both channels.  I was not talking about overclocking in any way or form; what I was saying is that if your memory DIMM spec is overrated, i.e. above PC3200, you may be able to do better than the AMD specs simply because you're then underclocking the memory.  While I haven't tried it I seriously doubt that you can get DDR400/1T with 4 full ranks on both channels.
There's also the point that even if the DIMM mfr has the same identical part number, the chances of getting an exact match on DIMMs purchased a year or so apart is slim.  It's also wise, when considering that a memory upgrade may be contemplated in future, to buy single rank DIMMs if available.
