Can the memory go higher? My best card (reference Asus) did 1120/1340 on water before it died mysteriously :D

All my other 4890's are in the 1250-1290 range.

max mem clock was 1300 , but his gpu at 1400 durring vantage gpu tests , this card can do on ambiental water ~1200 , on chilled water 1260 and single stages 1300( speak about my units) is picked from ~15 pcs over time:D

 

ram clock make a huge difference when you play with gpu hight, hight mem bandwith archieve better bench fps!
