Radeon HD 4770 based on RV740 processor made in 40 nm process technology. With the premiere of new video cards, gave to the question of the possible overclocking possibilities. The answer is clear – Radeon HD 4770 offers great opportunities for OC.

Main disadvantage is a Catalyst Control Center, which does not allow user to overclock his video card hard enough. 830 MHz for GPU and 850 MHz for memory.

This simple change will allow virtually any sample of card for stable operation at clock frequencies of 900/1100MHz core and memory. How to inform service Expreview.com (which revealed how to remove this limit) using a better cooling system, is quite possible to overcome the limit for the 1 GHz barrier core. The same expectations we had in the case of HD 4890, but it is his younger brother has a greater predisposition.

Is also quite likely that it will allow AMD to its factory overclocking accelerators. If this is the Radeon HD 4770 to move towards a worthy opponent for the card more efficient than the GeForce GTS 250.
