Asus P4B533-E and Intel D845GBV in the test: i845E against i845G, i850E and i845D

Stabi lity

The P4B533-E didn't particularly surprise us in terms of stability. Like almost every current board, it did its job without any problems and gave no cause for complaint. It was able to complete our tests without a single crash.


Asus goes overclocking the known way and divides these functions on bios and jumpers. The VDimm voltage (2.6-2.9V) can now also be set directly in the BIOS and you don't have to set a jumper on the board, as you had to do in the past with Asus.

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 more extensive options.

The FSB can freely choose from 100-200MHz in 1MHz steps and the multiplier from 8.0x to 24, 0x can be freely set at intervals of 1.0. The DDR-RAM can be addressed with both 100 and 133MHz. The clock ratio can be changed from 1: 1 (133MHz) to 3: 4 (100MHz).

We were very pleased when we finally added the function for adjusting the AGP/PCI clock in Asus' BIOS found. This function is particularly important with a Pentium4, as it can usually only be overclocked via the FSB. With the AGP/PCI clock function in the BIOS, Asus now also enables its customers to fix the AGP/PCI clock at 66.66 or 33.33MHz, so that no other components of the PC are overclocked when increasing the FSB.

The core voltage can be increased in the BIOS from 1.5 to 1.7 volts in 0.025 volt intervals. If you put an over-volt jumper on the board, you can even increase the core voltage in the BIOS up to 1.80 volts. With the Willamette, you can also choose between 1.75 and 1.85 volts in 0.025 intervals. With the over-volt jumper, you can even reach 1.95 volts.

In our test, the memory ran with the timings 2,2,2,5. You could have set CL1.5 in the BIOS, but our RAM refused this fast access time.

Asus has therefore incorporated very useful additions into the multi-language BIOS, so that overclockers will also feel reassured in the near future this board.

FSB check: The obligatory check of the front-side bus was also on the P4B533-E and the picture was almost typical for Asus .

The FSB was 134.66MHz and the resulting 538.64MHz QDR bus missed its ideal value a bit more clearly. With the multiplierOur Pentium4 2.4 out of 18 resulted in a total of 2423.86MHz.

The P4T533-C showed in our test that Asus can specify the clock rate more precisely.
