Shuttle AN51R Motherboard ReviewFormer staff writer -
As you can see, from the main BIOS screen, there are 8 sections that can be entered. They are:
In addition to those sections, you also have the options to:
Most of you should already know your way around the basic functions of the bios, so ill just skip to the important parts needed for overclocking. To achieve our overclocking goals Shuttle has given the user the ability to raise the HTT bus up to 280 from the stock 200. The HTT bus acts much like a traditional FSB allowing 1MHZ increments on the systems bus speed.
You also have the ability to change the memories timings to help dial in a stable overclock when running memory past its rated speeds. Couple this with AMD’s Cool N Quiet technology you can dial in a lower multiplier allowing you squeeze ever last bit of bandwidth possible thru HTT bus overclocking. Cool N Quiet, when enabled thru the bios, slows the computers speed down when at idling, this gives longer chip life, and can help your athlon 64 live a long and fruitfull life. Basically what it does is drop the multiplier and fan speeds in your system when full speed is not needed, a side effect of this allows us to lower multiplier below stock settings, and hopefully gain memory bandwidth by increasing the HTT bus. And we all know increased bandwidth is a good thing.
I must say I wasn’t expecting this many voltage options on a Shuttle mainboard. Giving you the ability t control ever important aspect of system voltage below is a list of voltage options.
|CPU Voltage:||0.80v - 1.70v in .25 increments|
|RAM Voltage:||2.70v - 2.90v in .10 increments|
|AGP Voltage:||1.60v - 1.80v in .10 increments|
|Chipset Voltage:||1.70v - 1.90v in .10 increments|
The only Problem I had was the ultra low settings for the CPU Vcore, some novie users might think that the lower number is what is added to the stock Vcore and this would result with a unstable if even bootable system, but there is plus to this; folks looking for a silent setup could lower the CPU Vcore to reduce heat giving the ability to use a Fan on the heatsink to help achive that silent dream. Not to many motherboards out there allow you the ability to go below stock voltages.
One of the new features offered up by the NF3 chipset the ability to run a raid array across both SATA and PATA drives. This is great as we finally have affordable PATA raid solution. User’s that have a lot of PATA drives will certainly appreciate this as it give them the ability the run there beloved raid setups with out having to purchase SATA drives of a controller card. This also gives you the ability to use a PATA drive as a mirror drvie in your SATA raid setup. The cross raid function offers up the ability to run RAID 1 , 0 ,0+1, or JBOD.
