AMD Athlon misidentified

  Epirb406 18:51 24 Jan 2004

Hi folks,

have just upgraded my CPU to an Athlon XP2400+ on an ecs K7S5A motherboard.(modest I know!)

On boot up it is being recognised as a 1900+

I have no concerns if it is just giving it the wrong name but is working as a 2400 but I would consider the dangers of a BIOS flash if the chip is being used to less than it's full potential.

Any ideas anyone?

Cheers, Epirb.

I think you are confusing clock speed (intel) with performance (AMD).

Come back for clarification if needed.

I need it.

As Mango Grummit is saying, the AMD 2400+ doesn't run at 2400mhz it runs at about 1900. The reason AMD gives for their numbering system is that in most applications the AMD is the equivalent of the Intel. In your case the AMD 2400+ is the equivalent of the Intel 2400 and will perform at the same sort of speed.
I believe that the latest Intel chips perform better than the AMD equivalents so perhaps they'll have to change this for their newer processors.

The Motherboard has recognised and is using the chip to full potential and I can heave a great sigh of releif and not go near a BIOS flash?

AMD measurement is given as Intel performance, ie, 1900 performs at same speed as would INTEL 2400 but with a lesser clock speed (and cost btw).

Just pleased I don't have to 'Flash'! Guess I will one day but at the moment am too frit!

Thanks all responses,

Cheers, Epirb.

Same problem with AMD XP2400 on K7S mobo, not reconized as XP2400.My techie explained as above,so I am satisfied with that.

I have an XP2500+. This is recognised as such if the clock speed is set correctly (166x11 = about 1830)in the BIOS. If it's set lower it says it's a 1900+. In Windows "system properties" it shows the name and model of the processor and then the clock speed so you can check this properly. (applies to Win ME, don't know about others)

The Athlon 2400+ should be set in the bios as 133MHz fsb and 15x multiplier. Its true speed is 1995MHz.

The best way to be sure of what is happening is to download the freeware tool Aida32 which will report everything about your CPU and indeed your whole system. You'll find downloads for it by searching in Google.

If this reports that the actual speed is much less than 1995 then look in the BIOS to make sure that the fsb is not set to 100MHz. Come to think of it, you could check that anyway.
