I have 6 identical Kingston KTD-PE313E/4G modules and trying to install to Dell PE R310 and T310 servers but with no luck.
4x DIMMs works but not 6x DIMMs. None of the modules are faulty. (I have already tried to replace them)
Solved: Turns out the Kingston KTD-PE313E/4G is unbuffered DIMM and according to the manual, R310 and T310 only support 4x U-DIMM or 6x R-DIMM.
