Foxconn A690GM2MA provides some overclocking options, but no memory timings settings. Here are the options you will find on Foxconn A690GM2MA (8.00.14 BIOS):

• Base clock (HTT clock): From 200 MHz to 400 MHz in 1 MHz steps.
• PCI Express clock: From 100 to 200 MHz in 1 MHz steps.
• Memory voltage: +50 mV to +600 mV in 50 mV steps.
• North bridge voltage: +50 mV to +600 mV in 50 mV steps.

The PCI Express clock configuration is very important, as you can lock the PCI Express clock at a given value (100 MHz, for example). Usually when you increase the FSB clock you will automatically increase the PCI Express clock as well, and sometimes your overclocking will be limited not by the CPU but by the devices connected to the PCI Express bus. Thus with this option you can increase the probability of setting a higher overclocking.

On this motherboard we could increase the CPU base clock from 200 MHz to 214 MHz, making our Athlon 64 X2 5000+ to run at 2,782 MHz, a 7% increase over its original clock of 2.6 GHz.

We didn’t play with the voltage configurations, so with time and patience you may achieve a better overclocking with this motherboard.
