omg & thx @xilolee :thumbsup2:
completely overseen, mixed types and the difference is a much slower Speed for the "4GX" Types: PC4-17000, 1.2V, CAS Supported: 9 11 12 13 14 15 16
while the "4G" runs at PC4-21300, 1.2V, CAS Supported: 9 11 12 13 14 15 16
thats the reason of the great hickup, they don't match in any way.
will wait with the latest dump which blames the nVidia, but with those mixed RAM :huh:
