| 90252 | 2002-10-17 20:55:00 | Hi, I hope someone can help me. I have just purchased a 2nd hand AMD 1000MHz AXIA CPU & installed it in my system, replacing an AMD Thunderbird 900MHz. The BIOS detects it as a 750MHz. The board I am using is an Iwill KA266plus with 512Mb 266 DDR. I have been to their site, read the manual, updated the BIOS to the latest version & it still won't detect it correctly. I have set the correct parameters in the BIOS manually & then it will post the correct speed, but when I boot XP Pro crashes straightaway, reset the BIOS & XP boots fine. Thinking my board may have a problem, I put the chip in my son's machine with a Soltek SL-75KAV/-X with Redstorm overclocking & 512Mb PC133 SDRAM but it also reports the CPU as a 750MHz, I set the CPU up manually in the BIOS but the machine won't boot & the BIOS reverts back to settings for a 750MHz. Does any one know of any problems with the 1000MHz AXIA or is it possible the previous owner had overclocked it & damaged it, he did mention that the AXIA should run stable @ 1333MHz although I havent tried this as I can't even get the damn thing to run at it's default speed. Any thoughts will be most appreciated. Thanks |

| 90253 | 2002-10-17 21:08:00 | I am not well versed in these matters but it would suggest your FSB is 100 MHz but should be 133 MHz? 750 x 133/100 = 1,000 |

| 90254 | 2002-10-17 21:16:00 | Hi, you are absolutely correct. Neither motherboard will auto detect the CPU at its' proper speed although both should. I have manually set the multipliers in both BIOS's to 133 x 7.5 but although the BIOS on one machine will report it as 1000MHz but then XP crashes into safe mode with a device failure message, which goes away if I reset it to 100 x 7.5, the BIOS on the other board refuses to let me set that speed, which I am assuming is a safety measure. Thanks |

| 90255 | 2002-10-17 21:21:00 | Sorry should also have said, The Soltek board's specs are "Thunderbird up to 1.5GHz, supporting Athlon Processors with 200 & 266MHz FSB" The Iwill's specs are "Supporting Athlon & Duron CPU's 1.5GHz & above with 266MHz FSB" |

| 90256 | 2002-10-17 21:28:00 | check your memory timings. expecially CAS setting. might have to drop it back a notch. | tweak'e (174) | ||
| 90257 | 2002-10-17 21:43:00 | Hi, Memory settings are set to auto on both boards. I just tried resetting the speeds on the Soltek & it crashed again, only this time I got ME's lovely & ever so popular missing VMM32.vxd messages. Guess what I'm doing for the rest of the day, before my son gets home from school & finds dad has trashed his machine. This is the 2nd time this week ME has crashed on VMM32.vxd, I had to re-install a freinds machine earlier in the week because of it. Anyone know of an easy fix apart from a reinstall. Back to the CPU, it is very strange that both boards report it as a 750Mhz as they are both auto configuring. I have pit my 900MHz Thunderbird back in the Iwill with no problems & put my sons 1200Mhz Duron back in his with no problems. Before I put the 1200MHz back in I tried a 1000Mhz Duron & it picked it up no problems. This has really got me stumped! Is it possible the chip is a 750MHz & the info on top of the chip is wrong? Cheers |

| 90258 | 2002-10-17 21:54:00 | sounds like it has a problem with the higher bus speed. seeing as you would only gain a measly 100mhz with the upgrade why not get something a little bit faster like a 1.4 t'bird ?? |

| 90259 | 2002-10-17 22:10:00 | True tweak'e, But what I want to know is, why does it have a problem with bus speeds over 100MHz when it is designed to run @ 133MHz & higher. Can the chip be damaged & still run? Cheers. |

| 90260 | 2002-10-18 00:42:00 | I have a manual for IWill KK266 - not sure if it's similar to yours - but there is a jumper to manually set FSB to 133Mhz | Peter H (220) | ||
| 90261 | 2002-10-18 00:50:00 | Just done some reading - I also use a Soltek SL-75KAV - and nowhere does it set FSB in the BIOS. This is done by dip switches on the M/B. What bios settings are you altering? Bye |
