Hi, I'm really hoping someone can help with this as it is driving me crazy.
I have an ML350 G6 with 1 CPU (X5670, SLVB7) and 9 x 8GB Registered DIMMs (72GB). The server powers up and works perfectly. The CPU was recently upgraded from an E5506 SLBF8.
I would like to install a second CPU and another 9 x 8GB Registerd DIMMs (taking the RAM to 144GB).
The trouble is, when I install the second (matched) CPU the server will not boot.
When the second CPU is installed, if I go into iLO then it does not show the latest hardware, it shows the hardware from the previous boot, which suggest it is not POST'ing correctly. None of the hardware sensors show any data.
I have been swapping parts to try to identify the issue, and am now really scratching my head. So far I have tried:-
- Adding a second 750W power supply.
- Replaced the system board. Note the system board has product code 606019 which supports the higher end Xeons.
- Added a fourth system fan.
- Switched around the CPUs; both boot in socket one with only one CPU installed.
- Switched around the RAM. All 19 DIMMs work in the sockets for CPU one.
- Reset BIOS/cleared NVRAM using the dip switch on the system board.
I did suspect a faulty system board, but unless I am incredibly unlucky and have two that are DoA, then I'm not sure what else this could be.
Am I missing an obvious BIOS setting?
I should add that the two LEDs on the front panel are green, the LEDs on the two power supplies are green and there are no error LEDs showing on the system board.
ANY help would be greatly appreciated!
