Overclocking the Gigabyte GTX 970 G1 [Updated 12/16/14]

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 (1329 Mhz is what Gigabyte has listed on their website, but you may notice the card runs faster when you game)
1752.8 RAM
1.2120 V

Overclock settings I used (use at your own risk):
+150 GPU
+500 RAM (this equates to +250Mhz to the RAM, as this is double data rate)
+10% Power target (for buffer)

1542.5 GPU
2000.7 RAM (8Ghz effective. GDDR5 is based on DDR3, which make the effective speed 4x the base clock speed)
1.2120 V (unchanged in my configuration)

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 multi-monitor games.

Furmark (, 1080 Preset:
Stock: Score: 4224
Avg: 70 fps
Max Temp: 65C

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:
Min: 31fps
Max: 55fps
Avg: 43fps

Min: 36fps
Max: 62fps
Avg: 51fps

Performance Increase: 18.6%

Crysis 2:
Min: 24 fps
Max: 43 fps
Avg: 32 fps

Max: 47fps
Avg: 37fps

Performance Increase: 15.63%

Update 12/13/14:

If you have any questions, feel free to leave them below or on YouTube. I’ve been answering a lot of questions over the past month now that the cards have been back in stock.

I updated the article above as well as the video regarding some confusion surrounding the “+500Mhz” to the RAM only equalling “+250Mhz”. I’m actually editing a video today that should go up later explaining the numbers you get when overclocking nVidia cards, since they made it a bit complicated. Quick summation is above, but the 2 minute video should clarify it and hopefully make it easier to understand.

Here’s a video explaining why overclocking the memory results in different numbers:
