    Question Memory - EEC Vrs Non-EEC

    I'm browsing hardware for a possible upgrade at the moment for my PC, and have come across EEC and Non-EEC memory. Non-EEC seems to be a bit cheaper, but I'm not really sure what EEC really is. I did a quick Google search and it looks likes it's something to do with error checking? Can anyone clarify what exactly it is and if EEC or Non-EEC is better for a gaming rig?

    You are right, basically when the machine boots up and uses ram some clusters of the RAM can have errors and therefore slow loading times up. If you have EEC it will check and reduce the amount of clusters with errors, thereby increasing efficiency. It does this on every scan cycle it uses (something like every 10ms or so)

    Thanks. Did a bit more looking and the general concensus seems to be EEC for servers, non EEC for workstations. Think I'll go for Non EEC.

    Your motherboard would need to have explicit support for ECC memory to make use of it anyway and the majority of consumer ones don't. Non ECC is fine for the vast majority of things.

    Not many gaming motherboards comes with ECC support - so I would check that out.

    Non-ECC will be fine though.

    ECC is error checking memory as above that is mostly used in servers. It works by having an extra bit or more for each byte of data in memory giving it a checksum. Because of this it is a bit slower than non ecc memory but is able to correct single bit errors in memory. These same errors would not be detected in normal RAM and depending on what was in that memory could easily bring down the whole system.

    Will just point out it's rare for gaming/consumer grade kit not to run on ECC memory, not that it matters too much. It's registered ram that most will swear at!
