Weirdman Posted October 4, 2019 Share Posted October 4, 2019 first off, hello everyone! I am new here and super excited to start using unRAID. I've recently inherited a boatload of servers from my employer when we replaced a bunch of individual servers in favor of blades in a couple of our offices. I am trying to use one of these as my unraid server and wanted to beef it up a bit. I took out 2 pair'd x5650's from a 1u dell and threw them into this 3u HP P4500 G2 server. Populating the 2nd CPU slot causes the thing not to post anymore. It will power on, the fans ramp up to the full jet fan screaming speed and then it shuts off. I can see online on ebay etc plenty of other examples of this server having dual cpu's but it just isn't working for me in this one. I've disconnected/reseated everything I can think of at this point and looked around in the ILO Management for clues and nothing really stands out to me. I tried running a known good CPU in socket 2 while socket 1 was empty and the same behavior occurs. At this point i've come to the conclusion that either the socket is disabled via software/bios/jumper or that the socket is just bad somehow/somewhere and I am SOL. Anyone have any other ideas? Thanks!!! Quote Link to comment

Thanks!!! Could be a RAM problem. Is the RAM configuration "for two cpus" correct? Normaly when using a second cpu, RAM config must be checked. What says the manual? How many modules min.? Dual-Channel, Triple-Cahnnel? How many RAM-slots? Population in which slots? If all is correct, check the RAM for function - if necessary, each module individually. Second guess: If the server was running with only one cpu, check the PSU - is it strong enough for two cpus? Edited October 4, 2019 by Zonediver Quote Link to comment
Weirdman Posted October 4, 2019 Author Share Posted October 4, 2019 So I confirmed the single socket would boot with 2 sticks of ram. Move that CPU and those 2 sticks to the same position for socket 2 and the same issuer persisted. It is currently running dual 750 PSU's the the power supply back plane. It's possible that there is an issue with the backplane and that the power rails for socket 2 are damaged. Unfortunately it seems that there is a single 8 PIN designed for both CPU's to be powered so I can't really test that. Quote Link to comment

Is the config "one cpu only in slot 2" ok for a bootup? read the manual first. As far is i know, if you use two cpus, you need at least 4 RAM-modules to boot properly and some Mainbords didnt boot if a singel cpu is populatet at socket 2...

Weirdman Posted October 4, 2019 Author Share Posted October 4, 2019 I will go check but the first time I had tried to boot it up I had all the slots populated with 16 GB sticks, 6 of the same sticks CPU 1 was using. Thanks! Quote Link to comment

Weirdman Posted October 4, 2019 Author Share Posted October 4, 2019 So it's entirely possible I don't know what I am looking for. I found the manual for this. But I can't find a section that calls out anything about memory or CPU configuration? Am I missing a manual somewhere? Thanks!!!! Quote Link to comment
