Just bought a nice i7-920 system with 12 gig ram. I'm trying to install proxmox-ve on it and to my surprise it only sees "only" 8GB ram:
# free total used free shared buffers cached
Mem: 8160224 2090876 6069348 0 68324 1660152

I did the "burnin" with a debian lenny install and that recognized my 12 GB just fine.
Of course VE is using older kernel than lenny, but i seem to remember reading in the forums about people with 16GB of ram.
Is there something like a boot parameter that i need to apply ?

AFAIK many people run with more that 8GB. Thats no problem because we use 64bit. Maybe there is a bios setting limiting RAM?
 
What does your Bios say?
I had something like that, I swapped the positions of the memory sticks and that solved it.
It had nothing to do with PVE, pure hardware related (some bad contact).
 
Try to boot it with an Ubuntu 64 bit live CD. If it still sees 8 GB, then I think something's wrong with your hardware.

It's new hardware (supermicro 5016T-MTFB)
I assembled everything, ran memtest86 for an hour, than installed debian lenny.
Everything seemed/was fine
Then i started experimenting with proxmox-ve and that's when i noticed i was
missing 30% of my memory. I'm currently testing (again) with memtest and it's
all red. http://dth.net/i7/memtest_i7_fail_12G.bmp
Isn't it funny memtest 1.65 thinks it's a P3 ? :-)

I've updated memtest to 2.01, it's a celeron processor now
i figured out what module is really bad, contacted the manufacterer.

Testing the rest (10G, so why did i only have 8G yesterday ?)

I think i have to review my burn-in criteria :
a full night of memtest before installing an os .

Thanks for the prompt replies.
