I recently installed two more sticks of GSkill 1866 4Gb each. I already had two 4Gb sticks of the same RAM installed. After installation i ran CPU-Z and under the SPD tab it says "JEDEC #5 is running at 761 MHz with CAS# 10", then the second entry is "JEDEC #6 is running at 800MHz and 11 CAS#". the last two both say "XMP-1866 running at 933 MHz and 8 CAS#". Is this normal? Is my older ram bottle necking my newer ram? Will this cause any lack of performance or problems?
