Hope I make sense. Speccy info follows my explanation.I am working on an old computer as a learning tool. It still has valuable info on hard drive. At start up,it tells me to go to bios and fix cpu speed.Hard drive and motherboard are running a bit too warm as wellI. Is it possible to correct cpu and fan speed in bios?

I am a rookie at this.

Hi,

 

Please visit...

Enter your motherboard model and download the manual in your choice of language.

 

You are looking for the Hardware Monitor section of the BIOS setup program for explanations of settings for the following...

1. Q-Fan Control
2. Fan Speed Ratio
3. Speed Up/Down Response Time

 

 

Best of luck and Please keep BC posted!

^ That covers the fan speed.  I see from Speccy that your CPU is set to run at 1100 mhz (11 x 100).  I suspect this is probably a default value until the CPU speed is correctly set.  None of them run this slow by design.  Unfortunately, I can't tell exactly what AMD Barton chip you have.  At a guess, it's either going to be the XP2500+ (166mhz x 11) or the XP3200+ (200mhz x 11).  The manual should guide you how to set the CPU speed properly (it's in Advanced Chipset Features in BIOS).  Basically, as these processors are multiplier locked (unless modified), you will just have to change the CPU external speed from the 100mhz it's currently set at.  The setting would be 166mhz for the XP2500+ or 200mhz for the XP3200+.  Both chips run at 1.65v.

 

As to why it's in a default state, is it keeping time and settings when powered off?  If not or if you haven't done already, I would suggest changing the BIOS battery.

 

There is a mix of RAM with different speed ratings and different manufacturers installed in each of the RAM slots.  This might be a cause of instability.

Better to tinker and learn from/with the old and apply what we learn to the new!

 

That old adage You can't teach an old dog new tricks is a bunch of baloney. I learn something new Everyday!

 

Never stop learning, and each day, look back and see what you've learned that day. If you come up blank, look a little harder, you'll be surprised what you find.
