Intel D875PBZ (Intel 875P Canterwood) Motherboard Review
BIOS
The BIOS setting in motherboards by Intel have been consistent for several years by now. This allows system integrators not to invest into extra training for own employees and system administrators.
In a separate section, the user can change the memory latency timings. "SDRAM Cas Latency", "Precharge to Active"(Trp), "Active to precharge" (Tras) and "Active to CMD"(Trcd) as well as some finer settings are accessible to change.
In this section, you can set the memory operating frequency: available are both synchronous and asynchronous modes.
What's more, there is a parameter in charge of the memory supply voltage (Vmem).
Its adjustment range varies within the nominal 2.625V to 2.775V (in 0.05V increments).
Now move on to the section to do with the system monitoring.
The board displays the following information: the main voltages, temperatures of the processor and the system (two sensors). Besides, the board keeps track of the rotational speeds of three fans.
It is important to note here that the rotational speed of the fans is in direct dependence on the processor temperature and air temperature inside the housing. In fact, if there is the apprehension that the processor's performance is downgraded as a result of overheating, then the fans can be activated to the full speed (i.e. set the "Fan Control" to "Disable").
There is one more feature worth to be mentioned - the so-called "onboard log" where all the alarms are registered.
Now a few words on the overclocking options. It is rather strange to see such feature on an Intel motherboard, but it is there (in the "Burn-In Mode" section).
In particular, the user can either increase the FSB by 2% or raise it by 4%.
As a result, the maximum possible FSB speed is 208 MHz, at which the board was running stably.
Clearly, this figure is definitely not enough for hardcore overclocking. Also, there is no way to raise voltage on the processor. Therefore, we can say that the "Burn-In" mode is intended solely for reliability tests.
The power converter uses a 4-phase power scheme, in which there are four 1200 mkF and five 820 mkF capacitors.
During the tests, the board demonstrated exceptional stability.
