Final answer:
The largest size fully buffered ECC 240-pin DDR2 DIMM sold today is 8GB.
Step-by-step explanation:
The largest size fully buffered ECC 240-pin DDR2 DIMM sold today is 8GB. DDR2 DIMMs are a type of computer memory module that are used in older computer systems. Fully buffered ECC (Error Correcting Code) DIMMs are designed to detect and correct errors in data, which makes them more reliable but also more expensive than regular DIMMs.
