MSI P45 Platinum Motherboard

MSI has used AMI BIOS for the past three years, and this has not changed with the P45 Platinum motherboard. AMI BIOS has come a long way since its beginning when it was a real chore to deal with; now it's extremely simple, and in fact can sometimes be mistaken for the cleanliness and ease of use that is the Award BIOS.


MSI puts its overclocking features under the Cell Menu. Until MSI changes its overclocking system from Core Cell, you will find all overclocking options under this menu.

In our first overclocking experience with the P45 chipset, we managed to pass just over 500MHz FSB with a total of 504MHz. This was done with only moderate voltage adjustments. We could have gone further, however, we didn't have a lot of time to do voltage tweaks before our deadline was reached. We will be re-visiting this board later on with a P45 overclocking and power saving article comprising this board and two others.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
