have traditionally been pretty good at overclocking, but seeing as how we're
still dealing with a beta motherboard we didn't really know what to expect. The
first thing we did was lower the CPU multiplier to 6x so the processor would not
limit our motherboard overclocking.
Going up a few MHz at a
time, the Gigabyte GA-K8NXP-SLI easily passed 210 MHz but we ran into problems
soon afterwards. No matter what we did we could not go 1 MHz above the 214 MHz
mark. If we tried, the system would randomly lock up while booting Windows or just lock
up at the POST screen.
Raising the voltages
(CPU, memory, HTT, core) didn't help get us one MHz higher, which was odd. We're
just hoping that these low overclocking results are due to a beta motherboard
rather than bad silicon.
To access the Advanced Chipset Features, we
must first press CTRL + F1 at the main menu. Once inside we can adjust
HyperTransport speed, the width of the up and downstream links and enable/disable
SSE/SSE2. As you can see the memory tweaks are here too and boy do
you get a lot of options!
The motherboard frequency can be adjusted
from 200-400 MHz in 1 MHz increments while the PCI Express clock goes from 100-150
MHz again in 1 MHz increments. I'm not sure what the Linear RGB clock does so I
left this at default. You can raise the CPU voltage a maximum of 0.25V, HTT 0.3V
and memory 0.2V. I'm not sure what the Core Power voltage control refers to
(perhaps NF4-SLI voltage?) but that can go up 0.3V too.
