Specs: XP pro & Vista home, 512
This question refers to the system using XPpro.

Have a question about the clock speed for the Athlon XP 1800+. I know that the 1800+ needs to be set at 133MHz, but I need to know which clock speed I should set it at within bios since I have two settings with the 133 reading:


Would like to know which one is best to use?
Thank You

The XP1800+ is supposed to run at 1.53GHz (11.5 x 133MHz). The settings you listed are for the CPU bus frequency/RAM bus frequency/PCI bus frequency. Ideally, it should be set to 133/133/33. Hopefully you have RAM capable of running at 133MHz...either PC133 or DDR266 (aka PC2100).

The size of RAM that I am using on this PC is 512MB
I am also using the program PC Wizard 2008 and it is showing that my processor frequency is 1533MHz (current : 1526.53MHz).

I set it at: 133/133/33Mhz
My current Processor Temperature is: 41 °C

In DXDIAG the processor reading shows: AMD Athlon(tm) XP, MMX, 3DNow, ~1.5GHz

If there are any other readings that you may want to look at just let me know and I will look them up with either DXDIAG, or PC Wizard 2008.

Your temps at 133/133/33 were just fine. At 100/133/33, you've underclocked your 1800+ from 1533 to 1150 Mhz. It's doing less work and runs a few ° cooler.
