JETWAY S447 ( SIS 645 CHIPSET ) / 1402 ( INTEL 845 MAC & ICH2 CHIPSET )

THIS REVIEW WAS KINDLY MADE POSSIBLE BY :

SPONSORS

We will be taking a look at two of Jetways P4 motherboards , the S447 sis645 chipset MB and the 1402 intel 845 & ich2 chipset MB , so take a seat , as both boards are like chalk and cheese , in fact the only thing these boards had in common was there rock solid stability . The CPU used on both boards was a 1.7GHZ P4 ( not a Northwood ) , and its overclockability was reasonable , reaching 1955mhz @ 1.75v on the Sis chipset MB and 2125mhz @ 1.85v on the Intel chipset MB . Neither MB allowed my USB mouse to be used before all the drivers were installed , so it was PS2 mouse to the rescue . Both MB's allowed for  emergency shut down should the CPU get to hot , via the BIOS, but only the Intel MB allowed for a temp warning to be set in the BIOS . I will take a moment here to just say that the User manuals for both MB's were just a little lacking , please Jetway , a little more care with the fine details . Now as for benchmarking both MBs , all benchmarks went in favor of the S447 .

 

Jetway S447 sis645 chipset.

This was the MB I tested first , I thought it a real shame that there was no manual Voltage adjustment for the CPU what so ever , there was how ever support for 333mhz DDR ram as well as 266mhz DDR ram .Setting up the bios was very easy , and there were no nasty surprises , unfortunately this Mb has no overclocking adjustments what so ever , and is more suited for system builders , dont get me wrong , this board is seriously stable , and easy to set up , perfect for system builders . If you are looking for a MB to base an entire production line of computers on , for general office applications , or students , a web surfing machine , then the Jetway S447 would need your attention , in fact at stock settings the S447 actually outperformed the Intel 845 based MB with all benchmarks by almost 5% across the board .

Jetway 1402 intel 845 / Ich2 chipset.

Again no nasty surprises setting up this MB , the only disappointing thing I found was the lack of support for 333mhz ram , my Samsung pc2700 ram running at 266mhz , well at least it worked , this MB is far more overclocker friendly , voltage adjustments for the ram , vid card and cpu , as well as 1mhz FSB adjustments to 132mhz FSB. On this MB I was able to get a extra 425mhz from the P4 cpu with a extra one tenth of a volt , thats 17 x 125mhz FSB . I would have really liked to have seen some more voltage to the cpu , as the P4 never ran into the 40's, doing 30 something deg Celsius all the time on both Mb's wit my Arkua 8568 doing the cooling . Now one of the important things to remember with this Mb is not to use anything but a 4x AGP 1.5v compliant ( capable ) graphics card , or you may fry ( kill ) your MB .

Conclusion:

The Sis645 Board gave better benchmarks due to the 333mhz ram speed , but the Intel 845 based board has more overclocking tweaks , obviously these Mother Boards are not meant to be in direct competition with each other , but made to suit the needs of a ever diverging market place , with consumers expecting Manufacturers to cater to their specific needs ,  the Sis645 would be perfect for System Builders ( not that I would recommend the  P4 cpu ) . With all the tweaks available in the Intel 845 based MB , it would make an excellent overclocking MB , unfortunately Jetway has been very conservative with the voltage adjustments , but as I have found out lately , those with really good overclocking CPU's wont need that much voltage in anyway ( not that it wouldnt be nice to have it available ) , but for those with average cpu's the extra voltage would certainly come in handy pushing the cpu to its potential . To sum up , both MB's were very stable , never giving a single problem of any kind , the only negative thing I have to say is on the Handbook , it needs a little work , other than that , my experience with both MB's was positive but unfortunately too brief  .
