Multiplier question, bios or hardware... ?
I own an old AOpen AX64 MoBo. I know a bios update can't give me a wider
range of possible FSB that Bios offers because these are the only ones supported by the clock generator of my motherboard (ICWorks W144H). But, is the clock multiplier a bios issue or is it related to hardware as this is the case for FSB? The Max multiplier for this motherboard is 8, Unicore software tell me that there is a new bios for this MoBo but never replied my mail when I asked what they mean by "support for faster CPU" so I want to know if this is possible or not. Thanks |

Thanks Don't bother with the Unicore software for running a faster CPU, at best you'd pay more than it'd cost for a better, more modern motherboard, and at worst you have a less-featured BIOS that adds no further support than already in the current AOpen bios. It would be advisable to flash upgrade the board to the last released AOpen BIOS now, before trying a new processor. Setting a multiplier is a BIOS issue, can also be detected by a motherboard to set this way, but the Intel processors have a "locked" multiplier that can't be set by the BIOS, so it's irrelevant what capability (or lack thereof) the BIOS has for the multiplier of the processor intended for use. The issue is whether the BIOS is configured to "unnecessarily" halt itself when it can't recognize the processor, or if it will attempt to continue. In general, AOpen boards don't unnecessarily halt themselves for lack of CPU ID, but it might display a model name or frequency that's a bit off at POST-time, which can later be checked (if running windows) by utilities like Sisoft Sandra or WCPUID, http://hp.vector.co.jp/authors/VA002.../download.html Because that motherboard has support for Coppermine processors, and support for 133MHz FSB, you should be able to run any coppermine processor, up to and including a P3 or Celeron 1.1GHz. While the product page only notes earlier support, if you check alternate location like the following link or newsgroup posts, you'll find evidence that the board will work with processors having higher multiplier than 8X. http://www.aopen.com/tech/report/cpuref/converter.htm If you have yet to buy a processor, beware that the Tualatain FCPGA2 Celeron and P3 processors aren't compatible, and also come in similar speed models in the 900 or 950MHz to 1.1GHz range.
