I recently purchased a X10SAE motherboard. I am using an Intel Core i5-4430 processor. I installed 4 sticks of Crucial 4GB DDR3 1333 (PC3 10600) ECC RAM. (Part# 51272BA1339).
The issue is that the Motherboard does not recognize the RAM as ECC.
X10SAE board supports E3-1200 v3 and 4th Gen Core I processor and both ECC/non-ECC memory. Since your i5-4330 does not support ECC memory per Intel specifications, non-ECC will be registered in the BIOS even if ECC DIMMs are installed.
