CPU Underclocked

[masonyes]

I have an amd XP 1600, the megahertz should be 1400. However it is running at 1050.2 mhz. The multiplier is set at 10.5x and the voltage is 1.728. I don't know what to change the bios settings to get it running at 1400.

Thanks

maybe the FSB frequency..but I would not play with that so much

Final frequency is FSB * multiplier.

(FSB = Front Side Bus)

So for a final 1400MHz with a 10.5 multiplier, you want a 133 MHz FSB.

If you're getting 1050MHz, it means your FSB is at 100 MHz, which is generally the default for older systems (so that they didn't over-drive older Athlon and Duron hardware that required a 100MHz FSB).

The 1600+ means that the performance would be equivilent to a 1600 mhz chip, although its clock speed really isnt that high (usually about 60-80%). This is a common thing that chip makers do, especially Cyrix in the mid-90s. Honestly, if you want to see a performance boost, buy a $30 sempron 2800+ or something that fits your socket and it will fix the problem!

The OP's post mentions the stock speed for a 1600+ is 1400MHz.

elvis hit it on the head - had the same problem with my 2200xp
