Diamond 7850 2G fitted with Acclero S1 + -OC and temps

[NeonGuy]

I ordered the ACCLERO S1 + $32 shipped for my diamond 7850 2gig.
Seems 1300 and memory over 5500 cause instibility. Sweet spot 1260/5500 1.215v might be able to get the volts down a lil more..

Stock heatsink idle/load 48c/72c load. After mod 34c/51c
on to the pics and temps...
Card at stock with shroud removed. note I removed shroud from day one and ran it nekid..
lots of l4d2.

Fitted with NEW heatsink installed with 120 mm

Temps with new heatsink mod,
51c after 3 mins
.


My 560ti oc 1000mhz i forget memory clocks

oc 7850 1225/1350

Nice results! I still have an AC Accelero on an 8800GT running passive that provided much lower temps than the reference HSF. Love those Accelero's!

I love those over stock but they take up so much damn room.

tried 1.225 still cant get 1300 mhz.

1.19 is insanely low for that OC, suprised you aren't seeing any improvement on 1.25.
