Through trial and error I discovered that the maximum amount of memory I could install was nine chip per side double sided. four sticks of 256 MB modules, for a total of 1 GB.

However, one of the modules that I installed was only eight chips per side as I did not have a fourth matching one. I am wondering if it is worth buying another nine chip per side module as I am wondering if ECC isn’t working because of it. Whether or not, I need ECC is kind of irrelevant. I’m trying to max out the system (just because) so if ECC can be functional, I want it.

so my question is does this motherboard/chipset even support ECC?

No idea about this mainboard/chipset, but as for the CPU there's this:

The Power 770 and 780, and future POWER7 high-end machines, have a spare DRAM
chip per rank on each DIMM that can be replaced with a spare. Effectively this protection
means that on a rank basis, a DIMM pair can detect and correct two and sometimes three
chipkill events and still provide better protection than ECC, as explained in the previous
paragraph.

i.e. seems like those 9-chip modules are used for protection beyond ECC, so assuming it turns out these boards support ECC, and the lower tier CPUs this chip fallback feature, then I guess you'll be wanting this too.

Personally, I'd probably pick up another one just to calm the OCD of knowing that one is different from the others...
