Hi all,

I've had a dl360p gen 8 around my lab for quite a number of years. Yes it's old and I should probably replace it, but I'm way more curious now that it's started giving me troubles...brain chemicals and whatnot.

Anyway, the system started having random reboots happen and 8 times out of 10 wouldn't address the entire 128GB of memory. Stripped the thing down and inspected it, bent CPU pins. No worry, now is my time to upgrade the two E5-2660 (v1) processors. Ended up buying two E5-2680 v2's. Swapped the system board out, fresh as it can be and left the 2660's in because of the hoard of updates that needed to be done prior to getting the v2's in and the new system board hadn't been updated in a decade it seems.

iLO4 was updated to the newest version (2023), system ROM/BIOS was updated to the latest version. Also had to run an Ivy Bridge arch update (hp-ivb_update-1.80-2) from 2014 that I suppose opens up the possibility of v2 CPU's.

After all updates had been completed I went ahead and swapped in the E5-2680 v2's. During post I'm met with a message of "259 - Unsupported Processor configuration detected. All installed processors do not have the same model number". Pulled the CPU's out just to double check and both of them have the exact same text on the front and indeed appear to both be E5-2680 v2's.

I confirmed that I could post successfully with one of the 2680 v2's instead of two, I double checked this for each processor just to make sure one of them wasn't bad. I went down the rabbit hole of processor stepping and confirmed they are each showing "stepping: 4" catting out /proc/cpuinfo. I reset the system bios/rom to default settings using the dip switches, still getting the same error. I've tried disabling turbo boost and hyperthreading with no luck. The only difference I've been able to ascertain was when I was in the linux terminal and catted out /proc/cpuinfo. One of the processor "cpu MHz" was reading 3600.000 and the other was showing "2783.429" which is closer to the base clockspeed of 2.8GHz, this was when I still had turbo boost and hyperthreading on.

I'm really out of ideas at the moment, other than trying to order another batch of E5-2680 v2's or maybe even step it down to the 2670 v2 or something. Any ideas would be much appreciated!
