Question I use your X8SIL-F mainboard with a Core I3 540 CPU and 2GB DDR3 Unbuffered non ECC memory modules, and found out that this combination was not working, after consulting the manual, I saw that I have to use Unbuffered ECC memory, but according to Intel Specification Core I3 processor doesn’t support ECC, so why is that? http://www.intel.com/support/processors/corei3/sb/CS-031175.htm Answer Intel is using the same Core i3 processor at both Desktop as server platforms So when Core i3 processor is inserted in to a server chipset platform, like with intel 3400/3420/3450 chipset,then the CPU will support ECC with UDIMM. On the other hand if Core i3 is pluged into a Desktop chipset mainboard, like with P55, H55… chipset, then CPU won’t have ECC support function. So with X8SIL-F using Server 3420 chipset,you need to install unbuffered ECC memory in combination with Core I3 processor. Was this FAQ helpful?
