At the end it depends on luck as overclocking never guarantee the same result with the same chips. But, the fact is very clear. Any Hynix BT-J, BT-D43 or DT-43 is a good chips and underated by many as they're not so popular among western overclockers. If lady luck is on your side, a good Hynix chips will outperform some average premier chips like TCCD in term of high FSB and tight timing. And with max vdimm on your board like 2.8 ~ 2.9v, the Hynix will always better than any Winbond BH-5/6 or UTT.
