Hi,

like always, thanks for your help Myles!

I steal one of the 8GB dimms and put it on one of my test machines I
configured coreboot to only initialize one CPU/CORE and therefore only
the 8GB. Booting with this configuration leads to the same result as on
the 128GB machine it hangs at the first memcopy it finds so the problem
seem to be the dimm itself but it is still DDR 2.

I attached the showroutes and dumpmem outputs.
