well so far running atitool artifact scan ive hit 865 core without artifacts or vpu recover (870 gives me vpu recover). before the highest i could hit was 815 without artifacts..
as for the ram i was hitting 1050 prior without artifacts now im @ 1125 and stoped as im happy with that.

Excellent

Great work, I think any other limitations will be down to voltage though. I havent seen many stable clocks over 870 with out voltmods.

Voltmods are not going to have much effect on this card. The cap before the card starts crashing is about 1.35V-1.37V on the core and 1.6V on the memory. Any more on either and you are in for a BlackSOD

Thought i should update this thread with some results using an 80mm fan blowing over the VRMs/HR-09
If you refer to post #19 you will notice that without the 80mm fan VRMs hit 80c after 2mins. This looks like a substantial improvement.
