Since the Pentium 4 2.66 died after a brief run in with an expert
around here, we have switched over to a Pentium4 2.8GHz for motherboard testing.
Unfortunately, this chip is not the best overclocker. Armed with the Vantec 470W
PSU though I was certain that the PSU would not be holding us back though.
We began to raise the FSB slowly, and at 140 MHz FSB we hit our
first problem. We had to up the CPU Voltage to 1.65V to help stabilize things.
We then continued to raise the FSB and we hit a maximum of 151 MHz FSB. Not the
best, but not bad either.
Iwill has always been very friendly towards the
enthusiast/overclocker and the P4HT-S is no different. There are a ton of
features from CAS Latency adjustments to FSB increments and voltage
As you can see from the Advanced Chipset options, we have the
usual CAS Latency adjustments, RAS to CAS Delay and Memory Frequency.
In Iwill's Smart Settings we can raise the FSB from 133-250 MHz in 1 MHz increments. There
are a whole load of AGP/PCI dividers even up to the 1/6 divider! If you'd prefer
to lock your peripherals at a certain speed, you also have the options of
66/77/88 MHz. DDR Voltage goes up to 2.9V and CPU Vcore can go as high as
2V even for Northwood P4's!
