Athlon XP 2600+ 266 FSB
Just fitted an Athlon XP 2600 Thoroughbred to my Gigabyte GA-7DXE
motherboard. When the motherboard is set to 133 MHz FSB, the system is very unstable and crashes whilst loading WIndows XP. If the FSB is switched down to 100 MHz, everything runs OK, but the cpu only runs as an XP 1900. Anyone have any ideas how to solve it ? I have updated the bios, but other than that there are no options in the BIOS to change anything much apart from the CPU frequency. I set this to 132 MHz and it runs OK (133 and over and it crashes), and shows as an XP 2600, so the chip must be OK (?), but I'm losing some performnace as the FSB is still down at 100. Is there anyway to get the FSB speed up whilst keeping things stable ? Temperatures are OK, CPU 45 and system 30. Voltages are shown around 3.35v, 5.1v and 12.25v. I assume this is OK ? My power supply is 300W. The voltage to the processor is shown as 1.69v. Is that OK ? I have read about 'vcore' is this it, and if so and it should be higher, anyway of upping it ? Hope you can help, I now have red eyes, no hair, and a fed up wife ! |

If the FSB is switched down to 100 MHz, everything runs OK, but the cpu only runs as an XP 1900. The speed is detected at boot time and the appropriate name shown on the POST screen!

CPU temp at 45 degrees is 'about right', but that should be at the CPU's correct speed?? If this temperature is with the bus at 100MHz it is possibly a little hot, so maybe it overheats when you turn it up to 133MHz?? Temperatures are OK, CPU 45 and system 30. Voltages are shown around 3.35v, 5.1v and 12.25v. I assume this is OK ? My power supply is 300W. The voltage to the processor is shown as 1.69v. Is that OK ? I have read about 'vcore' is this it, and if so and it should be higher, anyway of upping it ? CPU voltage should be 1.65v, so that is OK. What rating is your memory - You need at least PC2100 (DDR266) to run at this speed? If you have slower than DDR266, then it probably can't handle a bus much higher than 100 - 115MHz. |
