    Hi all, first post, looking for some advice on troubleshooting this issue.

    I picked up one of the cheap LGA 1155 Inventec motherboards off eBay a few months ago and paired it with an old E3-1240 I had laying around.

    Everything works fine when I run this setup with DDR3 ECC RAM, but when I try to run regular DDR3 UDIMMS i get 4 beeps. I get the same 4 beeps when RAM is not seated properly or when i use incompatible RAM, so I'm positive it's a RAM issue.

    The DDR3 sticks I'm using are known good, and I've tried every configuration I can think of, single, dual, quad 2gb and 4gb sticks, but I always get the 4 beeps unless i'm using ECC RAM.

    Is this a compatibility issue, or something else? The Xeon appears to be compatibile with UDIMMS, but I can't get it to work at all.

    Any advice appreciated.

    Probably a limitation of the motherboard you are using. The CPU is compatible with non-ECC RAM.

    The issue is probably the chipset. If your board is like the Inventec 1155 board I bought, it has a C202/204 chipset. C202/204 don't work with non-ECC RAM. C206 & 216 did, but the Inventec have the lower end chipsets with less compatibility.

    That does make sense then. I tried an i3 2100 in the board the other day and it didn't work with the DDR3 either. I'll check the chipset when I get home and i bet it'll be one of the ones you listed.

    Thanks!

    Your motherboard may be workstation type
