Grafikkort N240GT-MD512-OC/D5 and N240GT-MD1G have the same memory interface - 128-bit, and the same frequency of the GPU and shader unit - 550 and 1340 MHz respectively. In fact, the only difference between these two models (with the exception of a few different designs of coolers) is the amount, type and frequency of "on-board" memory. If N240GT-MD1G has 1 GB of GDDR3 memory with a frequency of 1580 MHz, the model N240GT-MD512-OC/D5 equipped than 512 MB of memory GDDR5, operating at high frequency of 3600 MHz.
Included with the video cards N240GT-MD512-OC/D5 and N240GT-MD1G includes overclocker utility MSI Afterburner, enabling to increase the graphics chip by 30 percent. In addition, the new MSI graphics cards have traditionally equipped with military grade components with high degree of reliability, such as - Capacitors Hi-c CAP, solid capacitors and solid state chokes. All this increases the overclocking potential of these products.
