Hi!

I added debug statements (http://pastebin.com/iSFstXmv) and realized
that the calculated checksum is 0..

CLC_CRC : 0
SPD_CRC : ce66

Furthermore I had a look at src/device/dram/ddr3.c line 155 - The
capacity is given with 4GB (as you see in the log) but the
dram_print_spd_ddr3 output from dimm->size_mb is 8192MB O_o

The first log was from a quite out-dated build - I reseted on
4679c41db292b80ce51c7d923e2f22258145522b..
