dimm is better, dimm is faster, most motherboards is designed to work with this type of memory..
I would use dimm because it is the newest fastest, and compatible with todays computers.

like pci slot dimms slot..
DRAM
DIMMs
Yes. The Intel CC820 motherboard has two DIMM slots that can use two single-sided DIMMs , two double-sided DIMMs or one single-sided DIMM and one double sided DIMM. In that case, the single-sided DIMM must be in the first slot.
If you install DIMMS in all four slots that don't match, the memory will still work, just not at top performance.
the system board receives important information from dimms regarding the ram configuration during?
The ATX form factor is an ancient one. Modules can range all the way from 72-pin DIMMS to DDR3.
The only difference would be if your motherboard has dual channel capability. Check your manual to see. If it does then 2 x 256MB would be the faster option.
Your motherboard supports dual channeling and you currently have two slots used in Channel A on the board. You want to install an additional 512 MB of RAM. Will your system run faster if you install two 256 KMB DIMMs or one 512 MB DIMM?
DIMMs are the newer tech.
ECC modules can be used in a non-ECC system (though the cost makes it a poor strategy). Buffered modules cannot be used in a system that does not support buffered modules.
