Check the specs on your CPU. The memory controller is built into the CPU chip, so the capabilities of the chip come into play here too: [URL] Memory Types: DDR3 800 Based on this, you'd need one of the X5600's to maximize the memory speed. Reason I asked about the BIOS versions is that IF there was after-market support added for faster memory types, functionality, reliability, etc., it would have been added with a BIOS update.
Before my question, below I show the equipment I'm usingPowerEdge R16102x Intel Xeon E55066x DDR3L 8GB 1600 ECC RDIMM 1Rx4 (all memory modules are equal)Memory sockets used: A1, A2, A3, B1, B2 and B3Memory mode: optimizer The R610 manual says"For single or dual-rank memory modules:• One memory module per channel supports up to 1333 MHz.• Two memory modules per channel supports up to 1067 MHz." As I'm using one memory module per channel, I'd expect a speed of 1333 MHz, but I'm being limited to 800 MHz (Total memory size in this case: 48GB)If I use only four modules instead of 6, with the sockets A1, A2, B1 and B2 being populated, I'm still limited to 800 MHz (Total memory size in this case: 32GB)What's wrong?Any help would be great!
R610 memory speed limited to 800 MHz
