Overclocking the board and BIOS

Overclocking Results:
HTT Multiplier: 5x 5x
Motherboard Speed: 200 MHz

224 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

The Foxconn NF4SK8AA-8KRS is definitely not an enthusiast's board, but we have had quite a bit of luck overclocking nVidia nForce4 SLI motherboards in the past, and we were hoping that this trend would continue.

Before I began the overclocking tests, I dropped the memory divider from 1:1 to 5:4 (166 MHz mode), so the memory would not max out before the motherboard did. I would have lowered the CPU multiplier too, but that option is not available in the current Foxconn NF4SK8AA-8KRS BIOS.

Starting at 200 MHz, I raised the motherboard clock speed in 5 MHz intervals.... but it did not get very far before running into problems. The system began to BSOD while booting into Windows at 215 MHz. Lowering the HTT multiplier to 4x seemed to solve this issue. Continuing onward, I was able to get the motherboard all the way to 224 MHz before things flattened out. Anything higher than 224MHz caused the NF4SK8AA-8KRS to simply stop POSTing. I guess this result shouldn't be surprising since Foxconn is not targeting overclocking enthusiasts with its NF4SK8AA-8KRS motherboard.

Looking at the NF4SK8AA-8KRS BIOS:

I was a bit surprised to see the lack of memory timing adjustments here in the DRAM configuration settings. Mainstream users should have nothing to worry about, as these are things enthusiast tweakers are always on the lookout for.

The Foxconn WinFast NF4SK8AA-8KRS is not an overclocker's motherboard. Motherboard frequency can be adjusted between 200 and 300 MHz in 1 MHz increments and you can also adjust HTT frequency as well as bus width. Maximum CPU voltage goes up 0.14V and memory up to 2.85V. Missing are any CPU multiplier adjustment options, and without these you will not be able to push the motherboard very high.
