Curious, according to Intel, it the i3 doesn't do ECC: http://www.intel.com/support/processors/corei3/sb/CS-031175.htm#10 http://www.intel.com/support/processors/corei3/sb/CS-031175....
But the Supermicro board says it can: http://www.supermicro.com/xeon_3400/Motherboard/X8SIL.cfm http://www.supermicro.com/xeon_3400/Motherboard/X8SIL.cfm
The board also supports Xeon processors, so it might be that it only supports ECC with Xeon. However, I didn't see anything in the docs to support this, instead it says "Dual Core processors of Ci3 and Pentium: support ECC UDIMM only"
I'm curious since I ended up springing for Xeon in my system specifically for ECC. Now I'm wondering if I made a mistake...
- wmf 15y agoIIRC, some vendors wanted to offer super-low-end dual-core servers but rather than create a dual-core Xeon SKU Intel decided to just not disable ECC on some of the Pentiums and i3s. (As if their branding wasn't f'd enough.) So yeah, i3s support ECC when used in a server board.

"The X8SIL/X8SIL-F/X8SIL-V supports up to 16GB of DDR3 ECC UDIMM or up to 32GB of ECC DDR3 RDIMM (1333/1066/800 MHz in 4 DIMM slots.)" Below are what we assume are ECC errors from an i3 based Backblaze pod, when this happens it is usually bad RAM (bad enough to crash the pods, replace with fresh RAM repairs it): ### IPMI LOG: #### ipmitool sel elist | grep -v "Fan FAN" 69 | 01/04/2011 | 20:21:52 | Memory | Correctable ECC | Asserted 73 | 01/04/2011 | 21:15:50 | Memory | Correctable ECC | Asserted
