Yea,I agree.......but not only this Gigabyte Z87 OC Guide,as others company OC Guide as well.
After many "new records" or "Total Domination!" and OC Guide for ES chips, from
various companies (persons), done all with Engineering Sample (ES) or Qualification Sample
(QS)............it's time to turn the page and start to look in RETAIL version.
Is nice to see what ES version can do........
but we all buying Retail version which didn't perform as ES.
