supermicro 2u hotswap hdd & ram install newbie question

According to the manual for that motherboard,

http://www.supermicro.com/support/manuals/index.cfm,

One dimm per cpu should be fine as long as they are the same size and type.

You should be fine with the setup you have for the raid arrays but make sure you set which drives you want to be hot swapable.

The manual makes no reference to one long beep but states:
"1 beep Refresh Circuits have been reset (Ready to power up)"
and
"1 continuous beep System overheat System overheat,"
so unless you are running into other issues I would guess that it may be what they are considering a short beep.
If you want to check, pull out the dimms and boot the machine and it should respond with "5 short beeps and 1 long beep" indicating "no memory in the system". This will show the difference between long and short beeps.

Perhaps you have the RAM in the wrong sockets, although it's pretty obvious by the naming convention. You need a DIMM in P1DIMM1 and P2DIMM1 on each server board.

Since it's two servers in one box you should be able to disconnect power from one board and see if the other runs OK.

even i try use 2 dimm per cpu P1DIMM1 and P2DIMM1, still the same, the continue of long beep still there.


when the server ship to me it send me us type power cord 16awg , 13amp. But here is using uk type, so i plug my pc power cord which is 10amp power cord. Does anyone know this will cause problem?

also base on the spec, the server will need hynix MT42GR7MFR4C-PB, but i use MT42GR7MFR4A-PB ram. Is this is compatible.

according to long beep mean bad pdu or overheat. when i tight the cpu passive heatsink, i give 5 half turn to each corner of 4 screw. OK? because i just no understand that 5.0kgf-cm ( 4.3lbf-in)

What heat-sink compound did you use between the CPUs and heatsinks?

heatsink snk-p0048ps , come with compound

this is the solution
