Amazon runs nothing but Xeons and Opterons, which require the use of ECC memory.
- hannibal5 13y agoXeons support both EEC and non-EEC ram. It' depends on the north bridge chipset on the motherboard if you must use EEC. Some Opterons require EEC, some don't.
- buryat 13y agoIt doesn't depend on the north bridge, since Xeons and Opterons have memory controller inside itself.
- hannibal5 13y agoI became interested of finding the answer. It seems that answer is no. http://serverfault.com/questions/433221/does-amazon-ec2-and-rds-have-ecc-memory http://serverfault.com/questions/433221/does-amazon-ec2-and-... >AWS does not comment on this question. The general consensus (based on seeing this question asked on SO, HackerNews, Reddit and so on) is that, unless AWS specifically tells you the instance type is running ECC memory, you should assume it is not. >Although unscientific and inconclusive I suppose this makes sense - ECC is a selling point, and the fact that AWS does not plaster "all our instances run ECC" on their info pages certainly suggests that they are not.
- bbgm 13y ago(My team owns product management for the Amazon EC2 instance platform) I wanted to clear up all the confusion on this topic and am cross-posting on other threads where this has come up recently. All the hardware underlying Amazon EC2 uses ECC memory. In our experience ECC is a necessary requirement for server infrastructure. We will be updating our detail pages/FAQs with that information.
