Asus P4T533 in the test: Next-Generation Rambus

Stability

Once again, there was no reason to complain about the stability. Although the bios used is still based on one of the first beta versions, there were no problems and the board passed our tests without any problems. The Rambus ran on 'Turbo Settings', which you can set in the BIOS as you like; This did not cause any instability.

Overclocking

Well-known in overclocking. Asus goes the old way again and divides the overclocking into bios and jumpers. With the front-side bus and multiplier you have the choice between bios or jumpers. They can either be switched using jumpers on the board, or conveniently in the BIOS, if the board is switched to 'Jumper Free' mode using a jumper, as it is supplied as standard. If you choose the 'Jumper Mode', the settings are made via DIP switches. Of course, the Bios offers due to thelimited possibilities of a DIP switch, the more extensive options, but at some point a protective function will switch on, which prevents excessive overclocking and is only possible via DIP switches.

The FSB can be set between 100 and 200MHz choose freely in 1MHz steps. The multiplier can of course also be set by yourself, if you are lucky enough to have an 'unlocked' Pentium4.

We were very pleased again about the option of the AGP and PCI clock in the BIOS fixed. So you can operate the PCI and AGP clock despite overclocking the front-side bus with 33 or 66MHz and is relieved of the risk that other components thwart successful overclocking. Asus already used this function with the P4B533-E, now it is finally following with the Rambus boards.

P4T533 Board
RIMM4200_2

Of course, the 32-bit 4200 RIMM is also officially from the i850E and is therefore not supported by Intel. Asus sees it a little differently and enables the Rambus to be addressed with “Auto”, “x3” or “x4” via BIOS. If you use a Pentium4 with 133MHz FSB and select the 'x4' option, the P4T533 clocks the Rambus with 533MHz.

The core voltage in the BIOS can range from 1.50 to 1.80 volts in 0.025 Volt intervals are increased.

FSB check: The front-side bus also runs a little beyond its intended purpose on the P4T533. The FSB clocks at 133.9MHz, which results in a QDR bus of 535.61MHz. With our Pentium 4 2.4GHz, which has a multiplier of 18, this effectively results in 2410.23MHz.
