dl380 g5 black screen on boot (after cpu upgrade)

Good day everyone,

i would like to submit an issue I am facing these days regarding an hp proliant (dl380g5) bought on ebay long time ago.

It came with a couple of Xeon 5140 (Dual Core). Once I tried to upgrade them, and replaced with a couple of Xeon x5470, fans went full speed and nothing came up except a black screen.

If I try to put back the old CPUs, the server starts correctly.

MOBO version is: 436526-001 and, according to the documentation I gathered here and there, it should be able to handle those CPUs. I also tried to update MOBO's firmware with no success (I mean, I managed to upgrade firmware but it didnt change anything).

Do you have any idea of what could it be? I am using the same heatsinks that I used with the Xeon 5140 pair.

 

I appreciate all your efforts and time spent trying to solve this problem with me, guys

Have a nice day

Daniele

Hello,

Usually if the processor is not supported, the Server should give a error message saying "805 -Unsupported Processor Detected" at POST.

If the screen is blank, it could be that processor is faulty.

Hi Suman,

thank you for your answer.

 

Could it be that both the Xeon x5470 are faulty? I tried to put them individually but nothing came up. Is there a way, in your opinion, to point it out as clearly as possible? I would like not to buy a new pair that might not work as well (maybe because this one isn't faulty at all)

Hi,

I would recommend to clear NVRAM S6 (CMOS) on this server so that server goes into default settings.

Refer to page# 86

IMPORTANT: If replacing the system board or clearing NVRAM, you must re-enter the server serial number through RBSU
