i875P Roundup - MSI 875P Neo-FIS2R: BIOS and Overclocking

The MSI board comes with an AMI-BIOS and as we soon are going to see, there are a lot of things to play with.


The system's bus speed, for example, may be defined between 100 to 500 MHz in 1MHz intervals. Naturally, this is way more than any CPU can handle today, but it feels good to know that we at least have the possibility. Regarding the memory speeds, they can be set to 266, 333 or 354 MHz for 533 FSB processors and 400, 500 or 523 MHz for 800 FSB processors. The AGP and PCI clock is of course lockable, but can also be set to anything between 33.3/66.6 - 75.5/151 MHz with 0.5/1 MHz intervals.


Now, on to the most interesting part of the board's BIOS - the voltages. The CPU voltage is definable 1.55V to a whopping 2.30V. The latter is certainly nothing we recommend, although it should satisfy even the most frenetic overclockers. The DRAM voltage isn't that bad either. Here we may choose freely between 2.50 to 3.30V (0.05V intervals). Last but not least is the AGP voltage, which can be raised to 2.1V (initially 1.5V). Does one dare to speculate in how many boards that'll be returned by RMA because of burned components?




Concerning the timings, the settings follow the standard recipe. 2.5-7-3-3 is the slowest while 2-5-2-2 is the fastest. The rest of the BIOS doesn't have any major surprises. The integrated components may of course be shut down or turned off at pleasure, and naturally, MSI also has a PC Health section. Below you can find a table of the most important overclocking settings.

BIOS settings
FSB frequency:
100-500MHz (1MHz intervals)
AGP frequency:
lockable alt. 33.3/66.6 - 75.5/151MHz (0.5/1.0MHz intervals)
CPU voltage:
1.5500V - 1.850V (0.0125V intervals), 1.60V - 2.30V (0.05V intervals)
DIMM voltage:
2.5V-3.30V (0.05V intervals)
AGP voltage:
1.5V-2.1V (1.5V-1.8V with 0.05V intervals, 1.8V-2.1V with 0.1V intervals)

Neo-FIS2R probably has everything one could ever want in a BIOS. Those who are looking for an extreme board for pairing together with a Prometeia, or some other kind of super-cooling solution, should really bear the MSI 875P Neo FIS2R in mind at the time of purchase. Words such as "voltage modding" are probably nothing we'll use when speaking of the NEO-FIS2R. Bottom-line, a more downright BIOS than this is yet to be found. Thumbs up for MSI that really shocked us with all its options. Our only complaint is the lack of a DualBIOS feature, similar to the one on Gigabyte's motherboard. But then again, we probably hadn't complained if it weren't for the Gigabyte board's contributory in this review.

BIOS/Settings
We look at the layout of the BIOS and the settings at hand, both for ordinary use and overclocking.


Overclocking

The overclocking went all to blazes, despite all the nice options, or more accurately not at all. Each time we rebooted the board with raised FSB settings, it resulted in a pitch-black screen. The board was assuredly running but we didn't get a signal. Of course, we tried with different memory modules but the result remained alike. We've together with MSI tried to solve this problem without success. Instead, we'll receive a new board shortly and test it as soon as the circumstances allow us to. We're afraid that we can't wait for a new motherboard as the article already is dreadfully delayed. We will do our best to update this section along with the benchmarks as soon as we can.

Here we evaluate the mainboards theoretic overclocking potential by the means of practical tests.
