Overclocking the Chaintech value board

With a 1 GHz HyperTransport link to the processor that is 16-bits wide both up and downstream, the nForce4 Ultra chipset can get quite hot. To tackle this problem, Chaintech has used a medium sized chipset cooler which works quite well, yet remains very quiet. During testing, the chipset fan did not make any noticeable noise and would not be audible when enclosed in a case.

Before we started to overclock the Chaintech Zenith VNF4 Ultra, we first lowered the CPU multiplier to 8x and the memory controller to 166 MHz mode. This way neither the processor nor memory would hold us back when overclocking. For these tests, we want only the motherboard to be the limiting factor.

Starting at 200 MHz, we began to raise the motherboard clock speed in 5 MHz increments. At the 220-225 MHz range, things started to become unstable, the board crashing now and then during boot up and while running SiSoft Sandra.

Increasing the chipset voltage to 1.6V seemed to fix the problem so we continued pushing it faster.

The VNF4 Ultra again started to show signs of instability at around 235 MHz. This time around we needed a bit more voltage; we had to go up to 1.7V to stabilize things. The Chaintech Zenith VNF4 Ultra hit its maximum speed at 247 MHz. Not the highest overclock we've ever seen, but very good for a budget board.

Inside the BIOS

In the DRAM configuration menu, we find our memory timing tweaks. There are not as many options as we've seen with other nForce4 motherboards, but then again this isn't an overclockers-only mobo. There are enough options for the mainstream user.

In the Frequency/Voltage Control section, we find the overclocking options. We can change the motherboard frequency from 200-400 MHz in 1 MHz increments but cannot simply type in the value we want. We can also change the PCI Express frequency but that is best left at stock speeds. Athlon64 users can select lower multipliers while FX users have full multiplier control. Maximum CPU voltage is 1.7V, memory 2.9V and chipset 1.7V.
