We installed the EVGA Precision X v4.2.1 overclocking utility to see how the EVGA GeForce GTX 750 1GB SC video card could be overclocked! You can use whatever software utility you like for overclocking, but this is the one we used today.
In case you forgot, the EVGA GeForce GTX 750 Superclocked 1GB video card already comes factory overclocked and operated at 1215MHz core (1294MHz Boost) and 1020 MHz base and the memory is clocked at 1253MHz (5012MHz effective). Let’s see how much higher we can get a this GM107 Maxwell GPU with 512 CUDA cores!
The NVIDIA GeForce GTX 750 is very similar to the GeForce GTX 750 Ti when it comes to overclocking as both share the same GM107 Maxwell GPU. This means that things are pretty locked down when it comes to overclocking. There is no way to increase the power target beyond 100% and all the cards are currently limited to a +135MHz GPU clock offset. We weren’t able to hit the GPU clock offset limit since this card already has a hefty overclock on it, so it really isn’t a big deal that NVIDIA locked down the overclocking sliders on this card.
We ended up with a GPU clock offset to +85MHz and the mem clock offset to +400MHz before we started to get encounter some stability issues due to the memory clock frequency. This overclock meant that we were running at 1456.7MHz at times thanks to NVIDIA Boost 2.0 on the core. This is pretty impressive and we were able to complete some benchmarks with stability issues with the core clock over 1500MHz. Maxwell is turning out to be a fun GPU to overclock!

EVGA GeForce GTX 750 1GB SC Overclocked:
By overclocking the EVGA GeForce GTX 750 1GB Superclocked video card we were able to take the score of 3911 and raise it up to 4257. This is a modest 266 point increase in our overall 3DMark score, which represents a performance gain of 6.7 percent. Our 85MHz core clock increase on the 1215MHz core is a 7% increase, so it makes sense that we are seeing a performance boost just shy of that in many of our game titles.
