Overclocking both Intel and AMD

SiS and overclocking generally tend to go together like oil and water, so we weren't expecting much from either the Intel or AMD platform in that respect.

Starting with the Intel 656 chipset, we first lowered the memory frequency so it wouldn't the hold the motherboard back, then started increasing FSB slowly from 200MHz. The ECS PF88 Extreme hit a maximum speed of 237 MHz with the Pentium 4 installed. We knew that it was the motherboard which had maxed out since the processor can clock much higher with stock voltage and the memory was not even running at stock speeds yet. Not bad for an ECS motherboard though.

AMD overclocking was more limited than with the Intel set up, but then again an enthusiast would not buy a motherboard like this for overclocking purposes. With no multiplier or voltage controls and a maximum motherboard clock speed of 232 MHz we didn't expect much.

The motherboard had no problem running at the maximum setting of 232 MHz, though we had to lower the memory frequency to run at 166 MHz mode. With additional frequency adjustments and voltage adjustments in the BIOS, the ECS PF88 Extreme might turn out to be a decent overclocker, for AMD processors at least.


We'll be looking at the Intel BIOS first. Here in the DRAM Clock/Timing Control we have the DDR2 memory timing adjustments. There are quite a few settings here and tweakers will enjoy pushing the system as much as they can.

In the Frequency/Voltage control section we can change the FSB from 200-450 MHz in 1 MHz increments and there are also a whole host of memory multipliers. The maximum voltage you can add to the CPU is 0.75V and memory 1.5V.

When the SIMA A9S is installed we get DDR RAM (not DDR2) memory options since the Athlon64 CPU still uses traditional DDR memory. The amount of tweaks here is less than we expected but should be good enough for the average user.

As you can see, Socket 939 overclocking is not very exciting. The only option that we have is to adjust the motherboard frequency between 200-232 MHz in 1 MHz increments.
