There are not many overclocking options in the BIOS, the vCore for example cannot be changed. Voltage adjustment for the ram and chipset is also unavailable. The only things you can do is adjust the Front Side Bus of the CPU and alter the FSB/DRAM ratio to speed-up or slow down the memory. Another thing is the absence of overclocking profiles.
Before you start overclocking don't forget to disable the Intel EIST and also disable the Spread Spectrum.
We used an Intel Pentium Dual Core E6700 3.2GHz CPU and a Cooler Master Hyper TX2 CPU Cooler for overclocking, the memory used was 2x1GB of A-DATA 800MHz DDR2 RAM. Our previous attempt with an E6300 and an ASUS G41 board resulted in an 18.5% stable overclock.
Raising the FSB with 20% and running HyperPi was succesful. After a few trials and errors we had a stable overclock @3854.9MHz, BCLK @321MHz. This is a 20.4% overclock on a G31 board even and better than the the 18.5% we achieved on the ASUS G41 board.
In general a 20% OC result can be considered as mediocre, but on the other hand you'll have to bear in mind that this is a very cheap mainboard with hardly any overclocking options.
MSI Dual Core Center
With the MSI Dual Core Center you can overclock a CPU in realtime, next to that you can also adjust the CPU fan speed if your motherboard supports it.
This tool also makes it possible to have various overclock profiles.
Easy OC Switch
Unlike the ASUS Turbo Key, which can be used with a 'closed case' by just pressing the power button, you'll have to open the case to set the switches. In the diagram below you can have a look at the options.
We tried the 266 --> 333MHz switch settings, which resulted in a crash after a minute or so. The Easy OC Switch is perhaps good for marketing this board, but is in our opinion pretty useless.
It would have been better if MSI had chosen more realistic OC settings like 266 --> 300MHz or perhaps indications like 10% instead of MHz.
On cheap motherboards from ASUS Turbo Key 'really works', allthough the overclock result you'll get is very limited.
More expensive boards from MSI have the OC Genie button, this tool is an itelligent way to figure out an 'automated overclock' and seems to work pretty well.
