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
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.
