ECS K7S6A with SiS745 in the test: The successor to the SiS735 is here

Stability

In practice, the K7S6A only knew two states. The perfect run and the endless loop during the boot process. If the right settings were found for each type of RAM after several CMOS clears, the board ran through our benchmark course without complaint. Since the system did not even want to go into the BIOS setup if the settings were too sharp, the way there turned out to be extremely tedious. Any manipulation that was too daring could only be reversed by repositioning the CMOS jumper. This procedure was repeated a good twenty times until the fastest, executable timings for all RAM constellations were found.

Overclocking

In our review of the K7S5A, we had to give the test person a straight six at this point, because the board had not been given a single option for overclocking the CPU, FSB or voltage. With programs such as SoftFSB or a hacked BIOS, brave users could still use the popular functions, but only inlimited dimensions.

But ECS seems to have learned from the mistake and has given the K7S6A a package of overclocking options in the BIOS. With the available bandwidth of the CPU voltage of 1.1-1.85V, the K7S6A even offers more than unusual fare. However, the low voltages should not bring a processor to life anyway. The front-side bus can be selected in fixed steps from the synchronous clock rate of 100/100MHz to 166/166. We have summarized all possible relationships in a table below. The K7S6A only offers changing the multiplier via a five-element jumper block. From 5.0-12.5 you can jump in 0.5 steps. It is not possible to increase the RAM voltage on the board.

The possible settings of the memory timings can confidently be described as rich. In addition to four predefined profiles ('Safe Mode', 'Normal Mode', 'Fast Mode', 'Ultra Mode'), variables such as 'RAS Precharge', 'RAS Active' and 'CLAS Latency' can be freely selected. However, the board vehemently refused to accept the CLAS Latency '2' setting. A known problem according to relevant forums. A BETA BIOS is supposed to get rid of this, but for our benchmarks we used the last, official version as always.

Possible clock ratios 100/100 133/133 100/133 133/166 103/103 137/137 107/107 143/143 110/110 157/157 112/112 150/150 124/124 166/166 133/100 137/103

FSB clocking :

With the 133MHz FSB set, the K7S6A clocks with 133.64MHz, which is compliant with the rules, which results in a clock rate of 1470Mhz in our XP 1700+ with a multiplier of 11. This is four megahertz above the theoretical optimum and therefore OKArea.
