Anand is terug en heeft het eerste deel van z'n Athlon Buyer's Guide gepost. Part I gaat over de op dit moment beschikbare slot-A modderborden, de Gigabyte 7IX, Microstar 6167, FIC SD11 en Asus K7M. Uit de overklok test (waarbij de multiplier van de Athlon werd gemodified, niet de busspeed) komt de K7M als beste naar voren. Busspeed overclocking is op dit moment geen reeŽle optie aangezien alle planken problemen vertonen bij busspeeds boven de 110MHz:
Other than physically modifying the processor card itself (or purchasing a pre-modified CPU) the only other option for overclocking your Athlon lies in the hands of the motherboard -- FSB frequency control. Out of the four motherboards we looked at (not including the Fester), only two offered FSB frequency adjustments, the ASUS K7M and the FIC SD11.
The default FSB for the Athlon is 100MHz (the "200MHz EV6 Bus" comes from the ability of the bus to transfer on both the rising and falling edges of the clock, thus effectively doubling the transfer rate) but you must keep in mind that overclocking the FSB on Athlon motherboards is much more of a sensitive process than on the BX boards we are used to.
The EV6 bus protocol is apparently not as overclocking friendly as Intelís GTL+, at least at this point in time of the Athlonís evolution, therefore the FSB overclocking options are very limited. Any frequencies above 110MHz should just be considered to be completely out of the question, meaning that the 124/133MHz of FICís SD11 are worthless because they wonít even boot. This limitation is obviously temporary as the EV6 bus is scalable up to 200MHz (200MHz x 2 = 400MHz), but for now donít expect to be able to use the FSB as a real overclocking option.
