SoDIMM Upgrade causing non-post

[motomat86]

So I was wanting to upgrade the ram from my work pc,  when they decided to go full remote, they sent us home a HP ProDesk 400 Mini G3,  (ugh, i know)  and it came with 8gb ram, locked at 2444mhz.  I bought a stick of 8gb to up it to 16gb, same speed ofcourse, made sure its compatible via the hp website.  2400mhz 1.2v in a 1x8gb form factor. HP's website for the Prodesk 400 G3 mini says it should be good to go. When installed, I get a bios warning light of 3 long reds, 2 short whites. HP's website for the user manual says 3.2 is a memory failure indicator.

 

OK, no biggie, I re-seated the ram, SODIMM is annoying with that, nope, same thing. I thought ok, ill update the bios, maybe the bios wont allow for both sodimm slots to be used. Nope, PC has the latest bios as of April 2021.

 

So I did my IT voodoo dance as i booted it up again after re-seating it, and sending it positive vibes, and nope, same 3.2 error. So I took it out and ofcourse pc boots up perfectly fine in 8gb form factor.

 

No idea why, or what was causing the error now, I am just wondering if something with the bios is locked to prevent any changes, since it is a work pc.  I dont know if its possible to lock down a hardware change via bios or something from IT before they handed out the pc?  In any regard,  Im not sure If I am missing something or why it wont work.   Feel pretty dumb to be honest.   Its just Ram, I bought it on amazon and clicked download now, why it no work

Does it work if you have only the new stick installed by itself?

Have you tried putting the new stick in slot 1 and the original in slot 2? HP generally likes SK Hynix or Samsung dimms, are the sticks identical sticks?

Could you provide a photo of the individual dimms? It may be that it is expecting matching sticks and doesn't post if they aren't matching.

i guess ive heard of kingston before, but yea, no dice on the crucial (one i bought) in slot 1 and kingston (oem) in slot 2.    guess i can just donate the ram to a lonely laptop or something
