Onze Russische vrienden van iXBT Labs hebben een review gepost van de Supermicro PIIISCD, een i820 plank met 2 DIMM slots. SuperMicro - bekend van z'n onoverklokbare server borden - blijkt voor de verandering ook overclocking features toegevoegd te hebben:
First of all, the board has a special jumper for manual resetting of the external frequency. The available values are: AUTO, 100 and 133MHz. AUTO also allows you to get 66MHz with Intel Celeron or old 66MHz Pentium II. Secondly, BIOS Setup of this mainboard supports an even broader frequency range: 66, 100, 105, 114, 120, 124, 128, 133, 138, 143, 148, 150, 152, 150 and 160MHz. On the other hand however, overclocking arouses some serious problems. And again as in many other cases it is Intel that hatches the mischief. FWH from the i820 chipset is clocked depending on the PCI bus frequency. But if you set the FSB frequency other than 66, 100 or 133MHz, the PCI bus frequency appears a bit higher than the required one. And since this hub doesn't prove very stable at higher frequencies, 124 and 128MHz FSB appear simply useless: the mainboard doesn't work at all. And as for the opportunity to set the PCI divider manually, Supermicro P3SCD doesn't have any, unfortunately. So, in general, if you want to overclock your CPU, you'd better do it on the mainboards by some other manufacturers such as the beloved ABIT, for instance, although it is possible to do it on Supermicro as well.
