ASRock G43 Twins-FullHD BIOS:

The motherboard BIOS is probably one of the most boring areas to look at if you're not an overclocker or enthusiast.  Even if you're an enthusiast, the BIOS on a mainstream board is generally devoid of tweaking features.  The ASRock G43 Twins-FullHD BIOS shows some promise in terms of overclocking, but as we'll see later, it doesn't actually deliver higher performance.  In the meantime, you hardcore users can check out the BIOS screenshots below.  This BIOS is pretty straightforward and we've only included a few of the BIOS screens that will be of interest.  Many sections like "Boot Order" have been left out as we simply can't handle that much excitement.  For now, the advanced bios settings will have to keep you happy - and tweaking your RAM, CPU and voltages until your heart's content.

In terms of tweaking, the CPU Frequency is adjustable from 100MHz to 800MHz in 1MHz increments and the PCIe Frequency is adjustable from 50MHz to 150MHz in 1MHz increments as well.  If you have an unlocked CPU, you can adjust the CPU Multiplier in 1x increments all the way from 6x to Unlimited.  CPU voltage can be adjusted from 0.81875v to 1.6v.  The voltages of both the Northbridge and Southbridge chipsets are adjustable in "Low, Medium, High and Highest" as well as "Auto".  DDR2 voltage can be adjusted from 1.8v to 2.73v and DDR3 voltage is adjustable from 1.5v to 2.2v.  All of this shapes up to offer a bit of promise for our test setup.

Basic hardware monitoring is present as well as support for saving BIOS setting to different profiles.  This is a nice touch if you've found settings that improve performance and want to be able to quickly choose some stock setting as well. Nothing too exciting in these last two screenshots so we'll carry on to overclocking.

 

Overclocking:

With all the adjustments that we just covered, I actually had some hope in this board when it came to overclocking.  We even used a QX6850 processor that has quite a bit of headroom for overclocking.  In Windows, I tried in vain to use ASRocks OC Tuner program.  Every time I tried to apply FSB settings about the 333FSB that the QX6850 runs at, the machine would lock up.  I tweaked voltages, RAM timings and switched the jumper blocks around in order to get some better settings and nothing worked in Windows.  Not to be easily defeated, I jumped into the BIOS to try out some BIOS level overclocking - which generally yields the best results in both performance and stability.  No matter what I did, I could not get the board to boot over 340FSB and even at that, results were unstable.  After about another hour of trying and many CMOS resets, I gave up.  With the QX6850 in the socket, this board is not overclockable at all.  Perhaps with a 266FSB or 200FSB processor your results will be different.

On the next page we'll cover some preliminary subsystem tests before we really jump into benchmarking.
