DIMMs are the newer tech.
rimms
RIMMs are traditionally faster and more expensive
72-pin SO-DIMMs, 144-pin SO-DIMMs, 160-pin SO-RIMMs and credit card memory
ECC
RAM (Random Access Memory), SIMMs (Single Inline Memory Modules), DImms (Dual Inline Memory Modules), RIMMs (Rambus Inline Memory Modules).
You replace C- Rimms with Rimms.
dimm is better, dimm is faster, most motherboards is designed to work with this type of memory..
ECC
DIMMs in servers can provide additional reliability if they use Error-Correcting Code (ECC) technology. ECC DIMMs can detect and correct single-bit memory errors, which helps prevent data corruption and system crashes. This is particularly crucial in environments that require high availability and data integrity, such as data centers and enterprise applications. By ensuring that memory errors are automatically corrected, ECC DIMMs enhance overall system stability and reliability.
ECC
No they are not compatiable they shouldn't even fit in the same slot due to the gaps at the connectors being different..and even fi you could get them to fit they run using different technology..ddr2 is double the date rate of the ddr..and s-dimms wow havent heard bout them in ages....
