Overclocking Galaxy’s GTX 750 Ti GC Slim without Limits
Features
The Galaxy GTX 750 Ti GC Slim is physically much smaller than the reference version. It is considered “LP” or low-profile and can fit into low profile and slim PC cases. It comes with the stock bracket, but for a limited time, the low-profile bracket is free with a GTX 750 or 750 Ti Slim purchase from the Galaxy store.
To the right, we see how much wider the reference version is than the Galaxy GTx 750 Ti GC Slim card when both are used together with the reference version dedicated to PhysX calculations.
The Galaxy GTX 750 Ti GC Slim uses custom cooling for the GM107 GPU which is also powered only by the PCIe slot and it is recommended that you use a quality 300W PSU as a minimum.
Let’s compare the Galaxy GTX 750 Ti GC Slim with the GTX 750 Ti reference version and pay particular attention to the Base and Boost clocks. You will also note that the Outputs are also quite different from the reference version.
Reference GTX 750 Ti Specifications
First, the specifications for the reference GTX 750 Ti:

Although Galaxy left the memory clocks unchanged, they have increased the reference base clock from 1020MHz to 1072MHz – or by +52MHz. The boost clock has also been increased from 1085MHz to 1150MHz. It will be interesting to see how much further our own sample overclocks and what its Boost will reach. We were able to take advantage of the very latest WHQL driver released yesterday which removed the +135MHz offset limit to the clocks and we also got a modded BIOS which removes the TDP limitations.
There is 75W total available to the GPU from the PCIe slot.

Display Outputs
Display outputs include one-dual-link DVI and a HDM connector as well as a VGA connector for a total of 3 displays that may be driven simultaneously from the Galaxy GTX 750 Ti GC Slim (right). The reference GTX 750 Ti (left) uses two Dual-link DVI connectors and a mini-HDMI connector.
No SLI
The GTX 750 Ti is not set up for SLI at all. We paired up two GTX 750 Tis, but dedicated one to PhysX and we will give those results also in the main summary chart.
Super-Widescreen 5760 x1080, Surround, 3D Vision Surround, and PhysX
The Galaxy GTX 750 Ti is set up for spanning 3 displays and can also handle 3D Vision with a 3D Vision ready display and the 3D glasses. However, for 3D Vision and for Surround, many games need to have their settings reduced drastically as the GTX 750 Ti is primarily designed for 1920×1080 and our benchmarks show it struggling even at 2560×1600. Just remember that you are playing across three screens for Surround and/or you are rendering each scene twice for 3D Vision!!
We are going to test the GTX 750 Ti as a dedicated PhysX card when paired with another GTX 750 Ti using 5 games which make good use of PhysX. It is an expansion of last week’s evaluation of the GTX 750 Ti as a dedicated PhysX card.
Head to the next page for the unboxing and then to the test configuration .
I cant find this card anywhere? Is it off market?
There are plenty GTX 750 Ti’s at Newegg:

hey Apoppin,
im looking for a low profile card for my htpc/mame/steambox rig. The issue is its only a 240watt power supply so this may not be the right card. The system only sucks 65watts right now so this card at 60 watts should be fine for the supply yeah?
It should be OK if your PSU really does supply 240W
