[SOLVED] Z800 does not see 16gb ram

[Mojo33]

Hey, I got an hp z800 and installed a 16gb ram but it only reads it as 8gb.
I tried the windows config where I can adjust the max ram but didn't help. You guys have some idea?
Cheers

What OS and how many CPUs ?
From what I understand for anything above 12 gb RAM you need 2 CPUs on the motherboard

See page 14

what the exact memory kit?
try each stick by itself?

Does the bios recognize it? If not, it's a hardware issue, possibly related to the the dual cpu capability as posted above.

Thanks for all the replies!!!

I read further and if the ram is not registered it only goes to 24gb..... Otherwise 96 and 192.... So now I am hunting down registered ram.

Wait, is that a 16gb ecc module? Because that should work.

As far as registered ram, I know where to get lots of it for $1/gb.
