When system has 18pcs memory populated, it doesn't boot and sound error beeps. One thing we can make sure that the MB is OK to boot and show POST when populated in DIMM P1-1A,2A,3A and P2-1A,2A,3A. And we tested with 4GB and 8GB module with fully populated without the problem. Is there any limitation in using 16GB?
MB: X8DTN+-F; Bios Ver : 2.1(2011.3.17)
Hynix 16GB 4R x4 PC3-8500R(HMT42GR7BMR4C)
X8DTN+ only supports up to 2DPC(DIMM Per Channel) for 4-Rank RDIMM, 12pcs for X8DTN+. This MB can support LRDIMM which can be fully populated up to 18pcs, that is 288GB for 16GB LRDIMM.
