Asus A7V266-E in the test: VIA KT266A part two

Stability

After we installed the of the board with the BIOS revision 1004 had done a few first test rounds, we were initially a bit skeptical about the issue of stability. The A7V266-E was the first board to surprise with a crash in Vulpine's GLMark. However, the update to beta version 1005 gave the all-clear. Except for the almost obligatory 'reset' in Quake3Arena, the board ran clean, extremely stable and above all a lot faster. The Asus A7V266-E also made a positive impression in cooperation with our 256MB Apacer CL2 bar. Even the sharpest settings as well as the '1T Command' still dreaded with the KT266 ran without errors in all applications. Friends of well-kept tuning measures should therefore find enough opportunities to tease out the last performance reserves.

Overclocking

Asus continues to devote itself to overclocking with a two-pronged policy. The Asus A7V266-E can be operated in both jumper and jumper free mode. While the jumper mode, as the name suggests, contains all the important settings directly on the board, the JumperFree mode switches the functions to increase theMultiplier and the FSB also free in the bios. The multiplier ranges from 5.0 to 14.0 and can be set in steps of 0.5. The FSB can at least theoretically be hunted to over 200Mhz via bios. Needless to say, neither chipset nor any other hardware would take this step. The voltage of the CPU, the so-called VCore, can also be manipulated. The values ​​are in the typical range of 1.70-1.85V approved by AMD. The DIMM voltage, however, is not found in the BIOS. But a look at the manual is enough to find the jumpers on the board. You can choose between 2.5 (default), 2.6, 2.7 and 2.8V. In the test we were able to run our Athlon C 1333Mhz stably with increased VCore to 1500Mhz. The RAM ran without problems even without the VDimm increase with the sharpest settings.

Note: Since Tomshardware.de found out in the summer of this year that Asus prefers to use a performance-increasing 134Mhz when the 133Mhz front side bus is actually set, we dared to take a look at the WCPUID tool from H.Oda. And lo and behold. Despite the selected 133Mhz, the FSB worked at 134 and the processor at 1343Mhz, i.e. 10Mhz more than it should. However, in order to prepare the board for the upcoming benchmarks, the latest BIOS (1005Beta 004) was installed shortly afterwards and the surprise was a success. With an almost perfect 133.39Mhz, the FSB proved to be absolutely compliant with the rules. Apparently, Asus has finally decided in favor of fair competition. In our opinion the right step.
