Ah-hah! So it is possible! (I asked a few times with vague results)

What models of RAM did you use, and approximately what was the cost?
Is it worth it in your opinion? ;)

Did the HP BIOS complain about component compatibility or try to
refuse to accept some details? (I saw other HP servers do that)

Hi Jim,

yes it's possible and after searching and comparing (and even had one shot into the foot as well) I finally figured that the HP would run with PC1333 organized in 512Mx8. I paid € 107,- (VAT incl.) für both modules.

At first my box would only recognize 8GB when I put both modules in, and I was only able to get it to run using one 8 GB and one of the remaining 4 GB modules, which accounted for 12 G in total. After hitting Google pretty hard, I checked in with the BIOS of my N40L and just tried out of curiosity to disable parity-checking in the Southbridge menu of the modded BIOS, which suddenly seemed to turn on the second 8 GB module… really weird. I am suspecting the BIOS to not perform a full discovery when I inserted the two 8 GB modules, but the 16 GB have been consistent available throughout 10 reboots, so I deemd them to operate.

As for the specs of the RAM modules I purchased, I can provide the information from the Sticker, that has been put on, hopefully you can get something from it - I also could ask my dealer what he exactly ordered from his distributor:

CSX:
8 GB DDR3 1333MHz
512x8 Long DIMM ECC
AP_ECC1333D3_8G
XECC-D3-1333-512X8-8GB

As I said, I think that the chip layout 512x8 is key here.

And yes… I do think that it is really worth it - running 3 VMs on the N40L really hits hard on the memory and with that more GB to spend my VMs really run much better (system load has increased, which is often a good sign in that regard) - after all I do have 9 GBs left where ZFS can operate on.

So, my N40L is now quite beefed up, without going too crazy… ;)

Cheers,
budy
