Duron 950 to Athlon XP 1.7+ in the test: AMD processor Roundup

Requirement

In most cases, there should be no problems running a Duron with a Morgan core. Therethe processor runs with a front-side bus of only 100 MHz, should it even be possible to operate it on quite old mainboards with VIA KT133 or SIS 730 chipset. The operating voltage, which has been increased to 1.75 volts, is not an obstacle here, as Athlon processors have been operated with this voltage for a long time. Only a BIOS update for the new functions of the Duron should be mandatory, so that the SSE functionality of the processor is also available. The processor was recognized on our test board, the Asus A7V266, with the latest BIOS, but after the first start this board wanted to tackle our Duron 1.1 GHz with 12.5x133 MHz, i.e. 1.66 GHz. Since this processor does not come standard with a multiplier lock, it would also accept this cycle, but operation with this cycle is of course not possible without extreme cooling. But the 11x100 MHz were quickly set by hand in the BIOS. The recognition of this processor left a lot to be desired here. However, since the BIOS is the first thing the user sees immediately after the processor change, this did not result in any further problems.

The operation of the new Athlon XP should also be possible without any major problems on most boards that provide a front-side bus of 133 MHz. With the introduction of the new Athlon, numerous mainboard manufacturers immediately published compatibility lists for their boards. In most cases, the Athlon XP was fully supported with a BIOS update. However, e.g. not at Abit. Due to a hardware problem, according to the manufacturer, there is an incompatibility between all Athlon XP processors and revisions 1.0, 1.1 and 1.2 of the KT7A with or without an integrated raid controller. Only the new revisions of the board fully support the Athlon with Palomino core. But other boards toocan have problems with the power consumption of the fastest Athlon XP processors. For example, an Athlon XP 1900+ couldn't be brought to life on our Asus A7V266 with 400 Leadmann power supply. The EPoX 8KHA +, for example, is said to have problems in individual cases when operating an Athlon XP 2000+.

By the way, with the introduction of the Athlon XP, motherboard manufacturers have strict regulations regarding the output of the processor clock. Since the name of the Athlon XP no longer exists in connection with the real processor clock, this real processor clock may no longer be output during the boot process. According to AMD, only the output of the model number or, in other words, the output of the performance rating and the processor name itself, i.e. Athlon XP, is permitted. Mainboard manufacturers who do not adhere to these specifications and publish corresponding BIOS updates no longer pass the AMD validation process.
