Review: Master of under-voltaging



We did all the tests with the MSI P55-GD80 because we have good support from MSI, so BIOS bugs get fixed really fast. Roughly two weeks ago we introduced you to the mainboard which is really a high-end part. We do not like all the three slot designs due to the limitations of the PCH (Peripherial Controller Hub). While it does support PCIe 2.0 all the lanes run only with half the speed. So, if they say it's PCIe 2.0 x16 @ x4 this is wrong, because PCIe 2.0 stands for double the speed compared to PCIe 1.x, so in reality you get PCIe x16 @ x2 speed. That is not something to be proud of. Also the price of around €185 is a tad too hight, at least compared to the next model in line, the P55-GD65 which is only a bit downsized (less phases, one PCIe x16 less) but at very competitive €130 price.

Of course the good thing is, the board is running fine in every environment, under-voltaging, normal and over-clocking - no problems at all. Also MSI did improve their BIOS big time. We always wanted to have default voltages either as setting or in the help screen. MSI decided to use the help screen. So you will always have a reference when overclocking. How to do so, we will explain later on.
