HP DL165G7 with 2x AMD 6134 target RAM: 48GB options:

2GB dual rank registered DIMM - 24 Qty HP-2GB 2Rx8 PC3-10600R-9 Kit
4Gb single rank registered DIMM - 12 Qty HP-4GB 1Rx4 PC3-10600R-9 Kit

which of the above is recommended for performance (ESX server)? AMD CPUs suffer any downgrade on mem bandwidth like Xeons?
