My 5300 kit had GTS and is still the only kit I have ever hit a stable 100% oc on. Found it as a dual kit languishing at the bottom of a clearance bin with 75% off .

Ive still got two of the xmd kits so ill pull the spreaders and see whats on them. Im thinking it was mixed PSC D and E actually. I ditched the mixed elpida kit as it didnt go high enough, but may have a pic somewhere. All kits were purchased as a lot from the same store on sale.
