yep, if it works, it works. no optimization necessary...
RAMs from different vendors are practically the same. the only reason some are more expensive than others is due to testing. some places have tighter threashold for what's acceptable and what's not - and those threashold are above and beyond whether the RAM works or not. accordingly, if one vendor has higher standard and discards more RAM as "unacceptable" for their standard (even if the RAM works fine), then RAM from that vendor will be more expensive and of "higher" quality.
let's say you need a score of above 60 for RAM to work. vendor A may say 70+ is acceptable while vendor B may say 90+ is only acceptable. though RAM from both vendors are likely to work, vendor B can claim to have higher quality RAMs.
