Considering the card is based loosely on the GTX570, itself not renown to be a huge base for overclocking, we didn't expect a great deal from this card however as you will see, the results tell quite a different story.
As you can see above, the MSI GTX560Ti-448 Power Edition/OC weighs in at an already overclocked speed of 750MHz on the core and 3900MHz (effective) on the 1280MB of GDDR5 so it will certainly be interesting to see how far the graphics card can be pushed.
As with all of our NVIDIA based GPU's and for the most part, AMD too, we use MSI's own Afterburner tool which has an intuitive, easy to navigate GUI allowing for simple, yet effective tweaks of both the memory, shader and of course the core clockspeeds. Voltages can also be adjusted and like today’s review sample, both the auxiliary and memory voltages can be tweaked too in the latest beta edition of this handy little overclocking tool.
We set off on our overclocking journey by giving the card a 10% boost in GPU clockspeeds which the card easily coped with. Any more than this and the card began to show signs of instability. Not the best of starts then. Undeterred, we increased the voltage on the core, sliding it to its maximum +150mv which allowed quite a formidable increase in clockspeed.
Reaching a truly amazing 1050Mhz on the core was some achievement. At this clockspeed it passed a 2 hour Furmark test without issue. Moreover temperatures were still very much in the comfort zone, never exceeding 68c which is a great achievement, especially when you consider the same cooler was used on the GPU which has less cores but had to combat much higher temperatures.
Not all of the benchmarks proved stable at this clockspeed though so we were forced to lower it slightly to a rock solid stable 1000MHz which cut through every one of our tests with ease. While the GPU gave us massive overclocks, the same couldn't be said of the memory. Sadly, any meaningful increase to the memory clockspeed meant the benchmark locked up, forcing windows to lose the device driver. Memory clockspeeds don't however have such a huge affect on the benchmark scores so while we would have liked a little overclocking headroom, MSI seem to have already done the ground work for us on this occasion.
