Given that they list both the standard memory and GPU memory next to each other, but only put ECC next to the GPU memory, it seems relatively likely to me that the standard server memory is not ECC.
- justincormack 15y agoBut Nvidia only sell Tesla's with ECC. I don't really read that implication into this. On the other hand, the fact that https://forums.aws.amazon.com/message.jspa?messageID=203167 https://forums.aws.amazon.com/message.jspa?messageID=203167 has never been answered suggests they do not, as they would answer affirmatively if it was true surely. Of course they may use a mixture. EDIT: Interesting that James Hamilton is on their team and thinks they should use it http://perspectives.mvdirona.com/2009/10/07/YouReallyDONeedECCMemory.aspx http://perspectives.mvdirona.com/2009/10/07/YouReallyDONeedE...
- EwanToo 15y agoI can well imagine that newer machines have it, and older ones don't, and slowly over time they'll end up with everyone using ECC. The costs involved were a lot higher 3-5 years ago than they are today.
