nVIDIA and its nForce chipsets are known to
be excellent overclockers so I thought it would be interesting to see how high
the ECS KN1-SLI Extreme could go. ECS does not have much of a history in terms
of overclocking but we will not let that hold us back. ;-) Before I began the overclocking
adventure, I first lowered the CPU multiplier to 6x and memory frequency to 166
MHz. I do leave HTT at stock, I am interested in seeing how high the motherboard
will go before I lower the HTT multiplier.
Starting at 200 MHz, I began to slowly raise
the motherboard clock speed in ~5 MHz intervals. Less experienced overclockers
should probably go a bit slower. The ECS KN1-SLI Extreme was actually a pretty
overclocker friendly motherboard to use and I did not experience any problems
until the 230 MHz mark. At this speed, the KN1-SLI Extreme had problems POSTing
or loading windows, the system would simply crash. Lowering the HTT multiplier
to 4x solved this issue and I continued to push the motherboard faster.
The ECS KN1-SLI Extreme motherboard actually
overclocked very well, and I hit a top speed of 260 MHz before things started to
fall apart. Anything above 260 MHz and I could not guarantee stability, lowering
the HTT multiplier did not help here. I have a feeling that chipset voltage was
the issue and if ECS allows for that option in the future, who knows!?
In the Advanced Chipset Features section in
the ECS motherboard we are first greeted by the overclocking options. The
motherboard clock speed can be adjusted from 200-400 MHz in 1 MHz increments.
HTT Frequency can be tuned between 100-2000 MHz with the HT multiplier, and
users can also adjust the up and down 'data width size.' CPU voltage can be
increased an additional 0.375V, and memory voltage can be raised to 3.11V which
is rather impressive for an ECS motherboard.
In the DRAM configuration menu we have the...
memory timing adjustments. ;-) Here you can adjust the memory speed as well as
the memory timings shown. Not quite as many tweaks as we have seen with other
motherboards, but you get the basics.
