AMD Sempron

  saxman 17:04 11 May 2005

I have just built a m/c around an AMD Sempron 2600 with a fsb of 333MgHz. The main board is an Asrock K7Upgrade-600. I have loaded WinXP Pro and on bootup the bios says that the cpu is an AMD 1700+ WinXP gives the clock speed as 1600 MgHz. I was expecting a clock speed of 2600 but the supplier tells me that this is equivalent to 2600 and the CPU is working ok. Can this be true?? Please help

Yes, AMD clock speeds do not match the processor names. And AMD 2600 will run at the equivalent of an Intel 2600mhz chip.

Your sempron 2600+ should have a clock speed of 1.83Ghz. the fsb setting should be 166Mhz and the multiplier set at 11 ( unless it is automatic )

If it is saying it is only running at 1.6 Ghz, you may have to alter the settings. click here

Sorry knocked enter by mistake before finishing.

A Athlon 1700+ ( as shown in your bios ) also has a multiplier of 11 but a fsb of only 133Mhz. This would give a clock speed of 1.467Ghz, very near the 1.5Ghz you say the bios is reporting. i would check in the bios to see if your fsb is running at 166Mhz as it should.

It should see it not in Mz but as it is a AMD 2600 cpu sheck your BIOS FSB is set to 166

It would seem that the motherboard jumpers must be set, before the bios can be set.

The jumper settings are click here and must be set for 333Mhz. They are located at No.13 here. click here You should then be able to set the bios to 166Mhz ( 333Mhz) and it should then show as a sempron 2600+ on boot up.
