I have been telling everyone about this because it caused me some frustration at first, All you guys have likely figured it out by now, but for those who are just now getting the board, this should help you get up and running without frustration.If you are not running ECC ram
, you have to disable the feature, which by default is enabled
in the BIOS.
Here is how.
Go to the advanced tab
Go to the NorthBridge configuration:
Once in there go to memory configuration and disable Memory ecc mode, unless you are running ecc memory. It will cause random shutdowns without ecc ram.
ECC RAM can recover from small errors in bits, by utilizing parity bits. Since servers are a shared resource where up-time and reliability are important, ECC RAM is generally used with only a modest difference in price. ECC RAM is also used in CAD/CAM workstations were small bit errors could cause calculation mistakes which become more significant problems when a design goes to manufacturing
Ecc Ram is usually found in servers, but without the extra memory module that ecc ram has, normal ram cannot function in ECC mode.
ECC Ram 9 memory modules
:*older generations of ecc ram had often had extra error correction chips located in the middle of the 5/4 divide, and some memory modules had more than just 9, but it is usually a multiple of 8 for non ECC and 9 for ECC.
Non ECC Ram 8 memory modules
If you look at the SPD tab of CPU-Z under correction it will tell you if you have ECC, if not it will say none or be greyed out.Edited by cook - 10/24/11 at 6:02am
