It turned out that if you set FSB – Memory Clock Mode to Linked or Unliked, then you get access to processor and memory frequencies.

Processor bus frequency is measured in quad-values and can vary from 400MHz to 2500MHz, which actually means from 100 to 625MHz in traditional values. The frequency setting in Linked mode depends on several dividers, in the Unlinked mode – you can set it to any value between 400 and 1400MHz.

The FSB & Memory Config page contains a link to the section with memory timing settings.

Nvidia nForce 650i SLI chipset differs positively from the popular Intel P965 Express not only by the asynchronous memory frequency setting, but also by the ability to support 1T Command Rate setting. Unfortunately, ECS NF650iSLIT-A mainboard has 2T set by default for this parameter and even if you manually set it to 1T, nothing will change: according to different utilities we used, the mainboard still works at 2T Command Rate, no matter what you set in the BIOS.

Advanced Chipset Features page gives you access to System Voltages where you can adjust the voltage settings.

I was surprised that this board allows to adjust the processor Vcore between 0.85V and 1.6V with extremely fine increment of 0.00625V. The CPU FSB voltage that is not that important during overclocking, can be set to 1.2, 1.3 or 1.4V. As for the chipset voltage adjustment, it is extremely useful for successful overclocking and on ECS NF650iSLIT-A, you can adjust the voltage of nForce SPP between 1.2 and 1.5V with 0.05V increment. As for the Vmem, you can only raise it to 1.95V with 0.05V increments. The voltage increase by only 0.15V is too low for good overclocking results. I am afraid that we will not be able to push the memory frequencies that far because of that and hence may lose one of the few advantages Nvidia nForce 650i SLI has over Intel P965 Express.

Now we only have to check out the PC Health Status page:

ECS NF650iSLIT-A mainboard can control system and processor temperature, processor and memory voltage and rotation speeds of two fans out of four that can be connected to it. if the processor cooler fan connector has four pins, its rotation speed can be set in dependence with the CPU temperature.

We were also pretty interested in the Load Performance Defaults parameter. The previous Elitegroup mainboards we reviewed would do different sophisticated tricks if this parameter was enabled. They would, for instance, reduce the processor clock frequency multiplier and at the same time slightly increase the FSB frequency, so that the end processor frequency could be close to the nominal. This time I couldn’t figure out how Load Performance Defaults parameter actually works, because the mainboard simply wouldn’t boot.
