Abit AN-M2HD mATX Motherboard

Overclocking

Overclocking
 
To start testing the overclocking capabilities of the AN-M2HD I started by entering the BIOS and accessing the Softmenu. From here I could alter the (rather limited) options allowing  me to reach the boards maximum potential.
 
From here, with the CPU Operating speed and Voltage Control settings, i had the ability to adjust the FSB, PCI-E clock, CPU and DDR2 voltages. For these tests I also set the RAM divider and HyperTransport multipliers to lower figures to make sure they didn't impede the CPU.
 
With a very low stock Vcore of 1.2V I really didn't expect to get much out of the little X2 4200 used in this test. I was reasonably impressed with the end clock however. While maintaining a 3 hour orthos session the AN-M2HD managed to keep the 4200+ stable at 2615mhz.
 
CPUz
 
While this result is no world record for 1.2v Vcore its quite impressive. There was one oddity that I encountered that I feel I shout point out however. As you can see from the CPU-Z screenshot the FSB obtained was 237.5mhz, when the BIOS setting was 240mhz. The board would boot and operate up to 2.8ghz, but it wasn't 100% stable.
 
I encountered another oddity next. Unfortunately I can't tell whether it's the motherboard or the CPU restricting the overclock as this is the first AMD based board we've had the opportunity to look at. But increasing the voltage didn't improve the headroom on the chip at all. With an upper limit of 1.50v the chip wasn't at all Orthos stable over 2.6ghz.
 
Finally the conclusion...

With HTPCs popularity on the rise, abit have released an AM2 board designed to couple with this growing market.

See how it fairs here

Good review there, Ham

I might build a second system on a board like that, processor for 40ish and any old ram, bargaintastic!
