Abit AN78GS Review

» Discuss this article (0)


I was impressed by the Abit AN78GS performance. In almost every game test, it had the advantage over the comparison boards. It was always a few frames per second over the top of the pile, except in Call of Duty 4, where it fell short at higher resolutions. Furthermore, the GeForce 8200 integrated graphics processor can allow great energy savings if the Hybrid power technology is turned on. It can also give a hand to a low-end discrete graphics card in graphics intensive applications, by working in SLI. This onboard device has three different connectors to plug to any display device. The old VGA is still there as well as DVI and HDMI. Moreover, The southbridge ID075C from NVidia used on that Abit board has also crushed its AMD opponent, the SB750. The performance is closer to the Intel counterpart, the ICH10R.

When it came to the time of overclocking, the AN78GS performed not too bad. A maximum stable external clock of 223MHz could be achieved. However, the maximum clock I could achieve on the processor and memory were not as high as I expected. But if we compare to boards such as the Gigabyte GA-M78SM-S2H, I am very proud of it. Furthermore, I didn't get any BSOD during the whole process! Isn't that wonderful? OCCT was there to notice me of an unstability.

However, there was also a downside. When I changed settings in the BIOS and then hit F10 to save and exit, it simply would not restart. And I didn't necessarily have to overclock to get this problem. Only changing settings like putting some on "Manual" and disabling fan control without changing any value would cause that problem. But what's weird is that if I changed only one or two settings at a time, it would be fine, compared as if I changed many. Another downside of the AN78GS is that the RAM slots are too close to the socket. If large heatsinks like the popular Thermalright Ultra-120 are used, one set of slots are unusable. Talking of heatsink, I was a bit disappointed by the GeForce 8200 one. The fins are thick and the heatpipe linking it to the voltage regulators heatsink is not even made of copper. I felt that under load, that heatsink stayed quite hot, which means the heat is not dissipated as well as it could be. One last thing, This board has only 4 rear USB ports, which is pretty limited for some people.

Overall, the Abit AN78GS is a solid board with great features and performance, for a relatively low price. I would recommend it to anyone planning on using an AMD processor along with a single dedicated NVidia graphics card. The integrated GeForce 8200 also makes it a great board for an HTPC build.
