Overclocking Tests with 975X Chipset

Experts Tip: Enable SmartFan in the BIOS

Foxconn's Fox One software fan controller works pretty well when set to manual mode, but SmartFan mode will not function unless it's also enabled in the BIOS.

To ensure that SmartFan is working, press the Del key at system POST and go to the PC Health Status section in the BIOS. There you will find the SmartFan options. All you need to do is make sure it's set to 'PWM mode'. If that is the case, SmartFan will automatically adjust the heatsink fan according to the values you set. The stock Intel LGA775 heatsink uses a PWM fan, after market heatsinks may not.

You can differentiate a PWM fan from the standard variety by the 4-pin fan power cable. Standard 12V DC computer fans will use either 2-pin or 3-pin fan power cables. The 3-pin connector is by far the most common as the third pin acts as an RPM sensor. In the above photo, the 4-pin PWM connector is at the far right bottom corner. This 4-pin motherboard CPU fan header is backwards compatible with the 3-pin fan variety, but the extra controls PWM fans bring to the table are specific to that class of fan.

Foxconn Overclocking Tests

Overclocking Results:
Stock Max. OC
Motherboard Speed: 200 MHz

255 MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

Foxconn has a pretty good reputation with us when it comes to overclocking, so let's dive into this with some big expectations for the 975X7AA-8EKRS2H motherboard and see where it takes us. Starting at 200 MHz, the FSB will be increased in 5 MHz intervals.

Overclocking commenced at 200MHz, and in no time the system was at 221 MHz and starting to show some signs of instability. This turned out to be the processor flaking out, not the motherboard, and was resolved by increasing the CPU voltage to 1.35V.

By the end of our overclocking session, the Foxconn 975X7AA-8EKRS2H motherboard had reached a maximum speed of 255 MHz (I expect it is the processor holding the motherboard back). An overclock to 255 MHz is what we have seen from a couple other motherboards we've tested with this Pentium D 840. With a 1066 MHz Intel Extreme Edition processor there is a good likelyhood that the Foxconn 975X7AA-8EKRS2H might go further. In any case, it's not bad considering the Pentium D 840 is running at 4.08 GHz (with a voltage of 1.45V) with nothing more than a stock heatsink.

Up next, PCSTATS noses around the BIOS before moving right along with SLI gaming and office benchmarks!
