BIOS
Battery
This is the only area where we had problems with the board as the initial BIOS upgrade we did caused problems with both the CPU being recognized and our SATA drives not showing up in the BIOS. We finally did fix this with a later BIOS update, but it was a pain while it was happening. After the latest BIOS update we did resolve these issues and move forward without fail. Do not use the BIOS that is offered on the NVIDIA website, use the one on the EVGA websites as it is tailored specifically for their board and not a generic 680i SLI BIOS update. The NVIDIA update worked fine on other boards, but for some reason the EVGA board did not like it. This was probably a fluke, but it has to be addressed.
The Phoenix BIOS that is on the board offers the user many different options for overclocking, including control for the system bus, the memory timings, CPU core and of course voltage. We were able to get very positive results using the EVGA 680i SLI in our lab and achieved an easy 15% above factory spec CPU overclock. We were able to do this without increasing the voltage and with stock air cooling as this is most likely how most end users will try to overclock their systems. This was very easy to setup and achieve as the motherboard is geared for this type of electric adventure. The CPU we got from our friends at Intel is also very overclocker friendly and makes for better results in these tests. With a little patience and some tweaking the EVGA NVIDIA 680i SLI board has major headroom for the enthusiast's user.
