ASUS P4S533 SiS645DX Review (3)
Overclocker 10 Apr 2002

Benchmarking

We conduct the usual tests on the setup with the following configuration :

Test System:

• Intel Pentium 4 ES 1.5Ghz
• ThermalTake heatsink/fan
• Maxtor 40G ATA133 7200RPM
• MSI Geforce3 Ti200
• 512MB Winbond DDR333 DDR
• Windows 2000 + SP2
• SiS1.09 AGP driver

In our tests, we ran the at Async DDR333 modes. The first is based on P4 1.5ES at 15x100, ram async at 166 (DDR333). The second test is reducing the multiplier to 11x133 (1.46G) and run it at async 133/166 and we compare the difference of running the same processor at 133Mhz (1.46G) and 100Mhz (1.5G)

DDR333 (100/166) P4 1.5ES

DDR333 (133/166) P4 1.46G ES

Summary

SiSoft Sandra 2002

Do take note that the results at 100/166 is based on P4 1.5G running at 100Mhz FSB. The other 3 results were based on underclocking it to 11x133 to see the effect of running at 133Mhz FSB.

It is not surprising that the P4S533 when run with a P4 1.46 (underclock 11x133) in fact outperforms the default 15x100 (1.5G) in terms of memory performance. It proves that running at 133Mhz FSB does in fact raise the performance. 

The next observation is that the ASUS P4S533 though running at most aggressive ram timings,the memory performance is still lags behind the SiS645DX ref board. This could be due to the fact that the Ref board clock generates a slightly higher FSB.
