I'm having some problems with a supermicro h8dme board with 2 K8 processors and 64 GB of ram.
Sadly, the ram is of two types (that was not my decision :/). We have 8x 4GB Samsung M393T5160QZA-CE6 and 8x 4GB Kingston KVR667D2D4P5/4G. Both of these types of ram are dual rank DDR2, 667 MHz, CL5, 1.8 V, registered, ECC.
The K8 memory code has some oddities which cause it to break down even if the SPD parameters you use are identical. Not only must all SPD timing parameters be identical, they also have to be stored at the same byte addresses in each SPD. I sent a patch for this to the list sometime last year, but it was never completely finished. I can try to dig it up if you want to take a look.
