mortisboy Posted January 25, 2012 Share Posted January 25, 2012 Source: Radeon HD 7970 OCP Mod released by phil from HWBOX.gr We all know phil and the fact that he managed to achieve several great scores with his Radeon HD 7970. Today, we are proud to be the world's first who reveal the new OCP mod for the HD 7970. So far it looks like it was a well kept secret, but phil thought was right to reveal it to us and then, to everybody else! Congratulations phil for figuring out the mod. We sincerely wish that everybody overclock their HD 7970 cores at 1700MHz or even more MHz - these cards do have amazing overclocking potential. Does the mod work? Of course! Before the mod, phil's HD 7970 could only bench 3DMark 11 up to 1550MHz core. After the mod, without pushing it much, it's already up to 1620MHz for 3DMark 11, and still has more potential! Well done phil, well deserved my friend! PS : With this mod, also Vdroop is being eliminated Quote Link to comment Share on other sites More sharing options...
Pt1t Posted January 25, 2012 Share Posted January 25, 2012 (edited) Are all wires going to the same trimmers ? Edited January 25, 2012 by Pt1t Quote Link to comment Share on other sites More sharing options...
K404 Posted January 25, 2012 Share Posted January 25, 2012 (edited) My interpretation is that it's 47K per phase. Same idea as the G80 & G92 OCP. The easiest way to do it is probably to tie all components together at one end and send them to ground. There should be ground spots nearby to offer a second method of soldering. Please can you measure the resistance of each spot, Thomas? That should tell us. If it's a fairly large value for each spot, then it's deffo one mod for each phase. NONE OF THIS IS CONCRETE, I HAVE NOT DONE THIS MOD OR EVEN SEEN A 7970 Edited January 25, 2012 by K404 Quote Link to comment Share on other sites More sharing options...
phil Posted January 25, 2012 Share Posted January 25, 2012 Are all wires going to the same trimmers ? No.They are going to 5 individual fixed resistors and all together in one gnd point.They can be seen in the picture with black cable insulation.
