ASUS 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 ASUS GTX 750 Ti was fairly good. We managed 1277/1355MHz on the core which was better than Nvidia’s reference design which managed just 1155/1220MHz. The memory was less impressive and managed just 1500MHz compared to Nvidia’s reference design which did 1688MHz. This is due to ASUS using 6GHz (1500MHz actual) rated GDDR5 Samsung memory chips while the reference design used faster rated SK Hynix memory chips. However, overclocking gave very good results overall thanks to the large GPU core speed boost.
