BL685c G1 and BL685c G5 memory limitations

Hi all,
could somebody explain me real difference between bl685c G1 and G5 ? They have the same bios, probably the same chipset (nVidia CK8-04, IO-04), use of QuadCore Opterons is possible in both generations.
We plans to upgrade our G1 to max possible memory (wmvare servers) using 8GB memory modules (or 16GB kit). According http://h18004.www1.hp.com/products/servers/proliant-bl/c-class/685c/specifications.html
G1 support 64GB RAM max - it looks we can not use 8GB modules.
G5 limitation je 128GB (same number of ram slots - 16).
Has somebody tested G1 with 8GB modules or could somebody confirm a real hardware limit of G1 and only 64GB of RAM?

Best regards,
Jan Soska

Re: BL685c G1 and BL685c G5 memory limitations

We bought additional memory to our BL685G1 servers, we run them with 80GB RAM and ESX3.5u2 (~30 VM) for 3months with NO PROBLEM
. System is rock stable. Our RAM config is 2x2GB module + 2x8GB module pre CPU x 4CPU = 80GB of RAM.
Additionaly, we upgraded CPU to newer AMD Quad-core Opterons. They are officialy not in support list, but as AMD has promised they are running well with no problem.
I recomend.

Regards,

Jan
