Asus P4T533-C and Intel D850EMV2 in the test: The new i850E with 533MHz FSB

Asus P4T533-C and Intel D850EMV2 in the test: The new i850E with 533MHz FSB


We that of Asus nor of most other boards, you are used to something different in the past. Despite its early BIOS phase, the P4T533-C offers no reason to complain about its stability. In our test, the board ran without any problems. The Rambus also ran on turbo settings, so there was no instability.


When it comes to overclocking, Asus takes the familiar route and divides these functions 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, due to the limited possibilities of a DIP switch, the BIOS offers the more extensive onesOptions.

The FSB can be freely selected between 100 and 150MHz in 1MHz steps. You can of course also set the multiplier yourself, but the Pentium4 throws a spanner in the works here, since it specifies the multiplier independently of the board.

Officially not supported, but still possible via BIOS PC1066 Rambus. Asus offers the option of addressing the Rambus with “Auto”, “x3” or “x4”. If you use a Pentium4 with 133MHz FSB and choose the 'x4' option, the P4T533-C clocks the Rambus with 533MHz.

The core voltage in the BIOS can range from 1.10 to 1.85 volts increased in 0.025 volt intervals.

Once again we had to miss the important option of the 'PCI/AGP fix'. Since the Pentium4 can only be overclocked via FSB, it is particularly important to determine the PCI and AGP clock at 33 or 66MHz. If this is not possible, the PCI and AGP clock is determined by the respective FSB and quickly prevents successful overclocking of particularly sensitive components.

In the FSB test, the P4T533-C surprised us a bit for Asus standards. The mainboard clocks very precisely with 133.64MHz FSB and the resulting 534.54MHz of the QDR bus can be easily represented. Our Pentium4 2.4 clocked at 2405.45MHz during the tests.
