What is EEC Ram?

Error correction code. used in places were reliablility is critical. Can detect and correct single bit memory errors, generating an error message.

What is a checksum?

a value calculated from a larger block of data, used to detect errors that may have occurred during transmission or storage.

What is most ECC RAM supplied as?

Registered DIMMs (RDIMMs) - It includes a register that reduces the electrical load on the memory controller, improving system stability. comes with performance penalty

What are spindle speeds?

the amount of rotations a tool makes in a second , measured in RPM

What is the most common spindle speed?

5400, 7200, 10000

What happens when you mix EEC and Non- ECC?

generally not supported and will end iin system instability or failure to boot.

What is a memory module?

printed circut board that holds a group of RAM devices acting as a single unit.

Identify this

DDR SDRAM packaged in DIMMs

When adding an odd number of memory modules or modules with different clock speeds and sizes, what outcomes can occur?
