It’s been a crazy two weeks, but I finally finished editing the overclocking video for the Gigabyte GTX 970 G1. The 970 G1 features Gigabyte’s Windforce cooling unit, which as of November 1st, 2014 appears to be the best heatsink assembly for the GeForce GTX 970 cards.
It’s been over 7 years since I overclocked a nVidia graphics card, so I needed a slight bit of refreshing on the subject. Unlike AMD cards, nVidia has no built-in overclocking tool, which means you’ll need to download some overclocking software. Along with that, you’ll want to download some other programs to make sure you’re overclocking correctly.

Stock Gigabyte GTX 970 G1 clocks:
1392.2 GPU
1752.8 RAM
1.2120 V
Overclock settings I used (use at your own risk):
+150 GPU
+500 RAM
+10% Power target (for buffer)
Effect:
1542.5 GPU
2000.7 RAM
1.2120 V
Idle clocks:
135 GPU
162 RAM
0.8560 V
Idle Temp: 33-36C
After toying around with the clock settings, I settled on the settings above. I chose not to over-volt the card, because I didn’t find it necessary. I ran Furmark several times during the process and didn’t get any artifacts, in addition to playing several mulch-monitor games.
Furmark (1.14.1.0), 1080 Preset:
Stock: Score: 4224
Avg: 70 fps
Max Temp: 65C
Overclock:
Score: 4956
Avg: 82 fps
Max Temp: 70C
Performance Increase: 17.14%
I then ran Saints Row 3 & Crysis 2 at 5760 x 1080 (3 x 1080P) completely maxed out. I averaged out 3 60 second benchmarks of gameplay for the titles. I tried to get a reference of an average gameplay session in these games.
Saints Row 3:
Stock:
Min: 31fps
Max: 55fps
Avg: 43fps
Overclock:
Min: 36fps
Max: 62fps
Avg: 51fps
Performance Increase: 18.6%
Crysis 2:
Stock:
Min: 24 fps
Max: 43 fps
Avg: 32 fps
Overclock:
Min: 27fps
Max: 47fps
Avg: 37fps
Performance Increase: 15.63%
