ASUS P4S800D-E SiS 655TX Mainboard Review (8)
Overclocker 24 Nov 2003

Conclusion

ASUS P4S800D-E is the first board that we reviewed that is based on the SiS 655TX chipset. SiS 655, 655FX is already a well known and accepted low costs chipset that powers the system to the 875P levels. As we can see from the benchmarks itself, the P4S800D-E running at a default of 200.09 has already exceed the 865PE and 875P boards out there. This looks very promising for a board which could definitely costs lower but offers similar performance levels.

In terms of features, the P4S800D-E is very well equipped. It comes with Gigabit Ethernet, 1394, USB. The best of all is that there are 4 SATA ports on board. 2 SATA ports with RAID 0,1 support is via 964 south bridge while another 2 + 1 IDE channel can be mixed and matched for RAID 0,1,0+1,JBOD. This makes the board one of the most flexible solutions out in the market right now. As discussed before in our SiS 65%FX ref board review, the SiS 655TX also supports the mix-n-match ram sizes. e.g. you can still run in Dual channel DDR mode with 3 sticks, 64M+128M in channel 0 +256M in channel for example. This results in dual channel of 192M x 2 and remaining 64M runs in standard non dual channel mode.

There are overclocking features built in and they include the voltage adjustments for Vcore, Vdimm and Vchipset. The only thing that I find it strange is that the CPU vcore can only be adjusted +0.1v of default FSB is selectable up to 300MHz FSB. There are also various async memory settings which I find that running in Sync gives much better performance than to run in Async modes. overclocking wise, we were able to POST up to 220MHz FSB.
