El_Capitan Posted October 15, 2012 Posted October 15, 2012 (edited) So, I re-acquired another reference HD 7970 after I sold mine. I basically got another HD 7970 with a full cover waterblock for the same price of one without a full cover waterblock... and it's a better overclocker! Graphics: Gigabyte HD 7970 3GB with EK Nickel @ 1195/1635MHz @ 1.131V's 140.1 Push + Pull (7V) Max 45C | 1270/1635MHz @1.2V's 140.1 Push + Pull (7V) Max 51C | 1310/1635MHz @1.3V's 140.1 Push + Pull (7V) Max 51C It seems that voltage is its limitation. I can go higher than 1310MHz Core Clock, but I start seeing tearing (like if at 1280MHz with 1.2V's). Still, at 1.2V's, which is a slight increase over the stock 1.131V's, 1270MHz Core Clock is a nice overclock, especially at 24/7.

Nyt Posted October 15, 2012 Posted October 15, 2012 Good clocks for those volts. Cards really show their true potential under water... For gaming, I can run 1300MHz and 1800MHz stable at 1.35V core and 1.7V mem. For benching, I can manage 1325MHz Core and 1875MHz Mem at the same volts.

Why so much voltage and overclock on the memory? Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted October 15, 2012 Posted October 15, 2012 Darn I was hoping for a HD7970 2GHz edition appreciation thread Sweet though!! Share this post Link to post Share on other sites More sharing options...
Nyt Posted October 16, 2012 Posted October 16, 2012 Why so much voltage and overclock on the memory? Because I can Still have to do some tests to see the levels in performance in games as I increase the overclock from stock to 1300MHz and 1800MHz to see what the gains are.
