Abit NV7-133R Motherboard Review

Most Abit boards tested at TweakTown have featured Abit's famous SoftMenu BIOS that features all the options you would ever require to tweak your system and then some. The NV7-133R had the SoftMenu BIOS, however, it lacked some very important tweaking options.


Instead of being able to adjust the FSB in 1MHz increments up to 200MHz, you can only set it to a pre-set speeds that are in 1-4MHz (usually 3MHz) increments. The maximum FSB available is 157MHz. As far as memory overclocking goes, you can set the CPU:MEM ratio to either 1:1 and 4:3. This allows you to overclock your CPU higher without having your memory as a bottleneck. There are two options for adjusting the VCore setting. These are "Std. Vcore" (1.74V) and "Raising" (1.79V). Considering most Abit boards such as the KR7A allow a maximum core voltage of 1.85V, I was expecting much more from the NV7-133R.


You can also adjust the CPU:AGP ratio, between the options 4:2 and 4:1.5. This will make sure that your AGP card does not become a botteneck while overclocking. Some very important features that were lacking from the NV7 were the ability to adjust the multiplier, DIMM voltage and AGP voltage.


Since there are no multiplier adjustments available, I had to limit my overclocking to purely FSB. The highest I could overclock my AthlonXP 1800+ (1.53GHz) to was 1.68GHz (11.5x146MHz). This was quite disappointing and I feel that with a few more tweaking options I would've been able to overclock this board much higher.


As far as overclocking is concerned, I was really expecting much more from the NV7-133R, especially considering that it is an Abit board.
