ECS GeForce GT 640 Review @ OCC

@ 2013/05/14
To overclock the ECS GT 640 we will be using the EVGA Precision overclocking tool. The GT 640 proved to be a decent overclocker, being able to be pushed from an already non-reference frequency of 930MHz to 1101MHz. We will see, however, in the upcoming tests that the effect of this overclock is somewhat hampered by the cut down shader count, the use of slower DDR3, and a 128-bit bus. This proved to be all the frequency that the GT 640 had in it with additional voltage having no effect in the pursuit of a higher overclock.
