MSI GTX 770 Gaming

Overclocking

The new Kepler Architecture with GPU boost has been a bit of a bear when it comes to pushing the clocks. This is due to the throttling mechanisms put in place and the fact that it dynamically clocks. Unlike 500 series where we could set a static clock and it just applied the card, Kepler clocks according to many variables, which means that much more care must be shown when applying overclock settings and even monitoring it during the run.

Things such as the thermal target can play a big role in stone walling your performance during an overclock session as everything has to be adjusted accordingly to ensure expected performance levels are met.

 

 

The MSI GTX 770 Gaming turned out to be an awesome clocker just like the reference card, taking the GPU from 1111 Boost clock to 1241 Boost clock which gave the boosted clock of 127MHz GPU by only setting the thermal target setting to 85C. There was no voltage adjustments as we try to keep the overclock simple and to what most users can set easily with much less risk to their components.

Memory much like the reference model rocketed from its 7GHz default setting to over 8GHz and was fully stable. For those of you who do not believe overclocking GPU memory does anything take a look at the score above as the GPU only overclock netted a 3DMark 11 Xtreme score of X3989 and upping the memory to 8GHz jumped the score to X4087 which is a very good gain for just Vram clocking.

This is excellent results and shows that the time and tuning that goes into the fan control, GPU Boost 2.0 and the card overall has been well thought out to have a card run at 1.2+GHz core and barely break into the 80C range and with no voltage adjustment as well.

TEMPERATURES

To measure the temperature of the video card, we used MSI Afterburner and ran Heaven Benchmark in a loop to find the Load temperatures for the video cards. The highest temperature was recorded. After looping for 10 minutes, Heaven was turned off and we let the computer sit at the desktop for another 10 minutes before we measured the idle temperatures.

 

GPU Temperatures Temperature (Idle/Load)
Nvidia GTX 690 32C/81C
Nvidia GTX TITAN 31C/67C
Nvidia GTX 680

31C/72C

Nvidia GTX 780 30C/65C
Nvidia GTX 770 34C/79C
MSI GTX 770 Gaming 32C/79C

The GK104 GPU seems to definitely run warmer but also having a thermal target means the card will continue to clock itself until it hits its target, so this of course means you can push the gpu farther due to the higher headroom offered by the better cooling solution. However this GPU simply did not wanna run up to 1300MHz mark and actually fell a bit behind the reference card in terms of clocking, though this is really just random variance between cards.

POWER CONSUMPTION

Power_Consumption

To get our power consumption numbers, we plugged in our Kill A Watt power measurement device and took the Idle reading at the desktop during our temperature readings. We left it at the desktop for about 15 minutes and took the idle reading. Then we ran Heaven Benchmark for a few minutes minutes and recorded the highest power usage.

Here the MSI GTX 770 actually falls a bit below the reference card which I find kind of funny being as it utilizes a dual 8 pin which gives off the idea that it will pull more power but even under load on the exact same test system it pulls approximately 25 less watts.

Undervolting the RTX 3080 and the RTX3090

What if you could find a way to lower both the temperature and the power consumption of your new GPU while still getting almost the same performance? Well, there is. It is called undervolting. Since the RTX 3080 and RTX 3090 came out there has been a lot of talk about undervolting them to get better thermals while still getting kick-ass performance and of course I decided I wanted to try it out myself. In the following pages you can both read on how to do it yourself but also get an idea how it will affect both the performance but also the thermals (and noise level).
