Are these cards using Samsung, Hynix or Qimonda memory chips?

These GeCube X-Turbo cards I am currently testing have 1ns Samsung chips

At stock they can do 1.1GHz 3DMark06 stable.

GeCube is using the HD3850 reference pcb for these cards.

They have configured VGPU differently and reworked the fan control.

The X-Turbo cooling seem to be just as good as the 3870 reference, but the fan made by Evercool is much more silent at high rpm.

When I bumped up the VGPU voltage from 1.305V -> 1.37V the card will do 900MHz easily
