Overclocking

 

We’ll use Gigabyte’s Utility to overclock. We’ll throw it in OC mode then jump into the professional mode where we can tune by hand.

We tried the auto-scan but it kept crashing the computer and would not recover gracefully so we gave up on it. We’re sure Gigabyte will resolve this in a future update.

As Turing has been power limited in every card we’ve tested, we’ll start out by just maxing out the power target which goes to a surprising 130%.

This alone gets us a considerable jump in our Timespy score over the stock 8883.

Most of our cards have been able to overclock the memory to 16GHz effective and Gigabyte is no different here.

We pushed the boost clock up 100MHz which did get us a bit, but GPUz shows we were limited to voltage.

Either way, this did get us another small boost in performance.

 

Power consumption
We measure power usage with a Watts up? .Net portable power meter with our Corsair RM1000 power supply.
Our 80+ Gold rated power supply runs with the following approximate efficiency:
10% Load – 89.1%
20% Load – 92.5%
30% Load – 93.1%
40% Load – 93.2%
50% Load – 92.9%
60% Load – 92.5%
70% Load – 92.0%
80% Load – 91.5%
90% Load – 90.8%
100% Load – 89.9%

At idle:
62W – From the wall
55W – adjusted for Efficiency.

OC’ed.

298W – from the wall
277W adjusted for Efficiency.

This gives us a GPU only power consumption for 222W at stock, quite a bit higher than Nvidia’s normal 175W TDP thanks to the 130% power target limit.
