![]() The overclock was straightforward to apply – MSI’s Afterburner worked flawlessly, and by using Crysis we could stress both the GPU and memory and problem-spot failed overclocks quickly. Furthermore, whilst the fan was almost at full speed (according to GPU-Z), it was reasonably quiet and was barely louder than our CPU cooler.ĬonclusionOverclocking the GTX 460 768MB proved very fruitful, with a large jump in performance that made our £175 EVGA card faster than a £270 GTX 470. The card peaked at a delta T 40 oC, which is much lower than other cards in the same price range. What was more impressive was that the GPU temperature was extremely low with this overclock applied. Unlike system memory, graphics memory can make a large difference to game performance - the overclock from 900MHz (3.6GHz effective) to 1,095MHz (4.38GHz effective) represents a relative large 22 per cent boost, and netted us a healthy increase in performance. ![]() The GDDR5 memory was also very overclockable. While not every card will hit these lofty heights, manufacturers have already started releasing cards with clock speeds as high as 800MHz - this bodes well for the general level of overclockability in the GTX 460. Our final GPU overclock took it from 675MHz to 858MHz, with the stream processors therefore overclocked from 1,350MHz to 1,716MHz. Our GTX 460 768MB was insanely overclockable, with extremely high frequencies easily attainable. ![]() We were therefore looking forward to a session in the labs to see what would happen.īy incrementally increasing the clock speed of the GPU and memory we found the maximum stable speeds of our EVGA card. That said, the greater amount of memory (quite a few games want to use 1GB) and fatter memory interface of the 1GB version might still give it the edge over even an overclocked GTX 460 768MB. ![]() This means that there are fewer active memory controller units in the GTX 460 768MB GPU the fewer the sub-units in a chip, the less to flake out when overclocking, so we expected the GTX 460 768MB to overclock further than the 1GB version. GeForce GTX 460 768MB OverclockingThe cheaper of the two GTX 460s is the 768MB version, which has a 192-bit memory interface rather than the 256-bit of the GTX 460 1GB. ![]()
