I want to congratulate you, but no matter how much the core frequency, you cannot change the one spec that is Elpida Memory.
At this point, if Manufacturers charged 10$ extra for Samsung memory cards, I would happily starve for a week to collect more
This is where the OC UK GTX970 is kinda gold, costliest GTX970 yet its built from higher quality components and 100% samsung memory guarantee. So far MSI,GBT,etc can eff off. Creating a premium OC'd version of a card, charging more than retail and then slapping in Hynix. Atleast OC top tier versions of cards should have Samsung Memory.
