Micco Posted December 2, 2005 Share Posted December 2, 2005 I'm building a new system listed below: ASUS A8N-SLI Premium AMD64 3700 2x TwinX CMX3200LLPT-512 XMS3205v1.2 eVGA 7800 GT WD 120 Antec TruePower2 550 I cannot get the system to post when ANY memory is in one of the "B" slots. I can put one stick in either or both "A" slots, but no combination will work in a "B" slot. I'm trying to figure out if this is a compatability issue with the XMS memory or if I have a bad MoBo. I've played around with memory timings, trying to loosen them up some, but frankly don't know what I'm doing. I've bumped DRAM voltage up to 2.8 in case the B slots needed a little more juice, but all to no avail. From all I've read, this memory should be compatible. But I do see one note in the fine print of the MoBo manual that says "Due to CPU limitation, DIMM modules with 128 Mb memory chips or double-sided x16 chips are not supported in this motherboard." I did see that someone else reported a similary issue on this site, but it appeared that he couldn't get A1+B1 to work together. I can't even get B1 or B1+B2 to work together although A1, A2, and A1+A2 work together. So I'm not sure it is the same problem. So, any idea if this is a memory compatibility issue? Any suggestions on what I should do next? Thanks! Link to comment Share on other sites More sharing options...
