KFA2 GTX 750 Ti OC 2GB Graphics Card Review

Overclocking & Overclocked Performance

The overclocking ability of a graphics card is an important buying consideration irrespective of whether the graphics card is low end or enthusiast level. I’m sure everyone will agree that the more extra performance from overclocking – the better. In our overclocking we push each graphics card to its maximum stable core and memory frequencies. Typically we also raise the power limit to the maximum and where possible raise the voltages if this results in higher overclocks being achieved. We always aim for “24/7” stable overclocks that DO NOT result in potential heat on longevity issues so if we do raise the voltage it is still kept within safe parameters. The latest beta version of MSI’s Afterburner software is the overclocking utility of choice: this is because MSI Afterburner Beta versions typically allows you to circumvent overclocking restrictions – particularly those set by AMD.

Overclocking on the KFA2 GTX 750 Ti OC was pretty solid. It managed significantly higher than Nvidia’s reference design which for us topped out at 1155/1220 MHz on the core, but the reference did better on the memory with 1688 MHz. The reason for the better memory performance on the reference design is because it used SK Hynix memory chips, this unit uses 6GHz rated Samsung memory chips so they are rated for 1500MHz~.
