Socket 7/Mobo problem

[smaxted]

I have an old beater of a computer that I was able to replace the proccesor on. Originaly it was a Cyrix 6x86 100mhz 120+ with a 100mhz bus speed and a 3.3v core with an Amd-k5 PR166 processor for it. IT has a 66mhz bus speed with a 3.52v core. The mobo manual specificaly has the jumper settings for my AMD (the jumper is a 4 notch on-off switch). Now since I replaced the Cyrix with the AMD the fastest I can get the mobo to reconize is 100mhz. It seems that every time I switch the processor Jumper 1 (there are 4 jumpers on the switch) doesn't seem to turn on. I have no idea what in the_______ is going on. Help would be greatly apppreciated. If you need any clarifications post and then I can reply. Thanks Again. Scotty Mac a.k.a smaxted

I have the same CPU in my 'parts' box. Can you post the make or model of the motherboard?

All I know about the mobo is it is a GA-586VX...hope it helps. Oh yah I tried an intel 200mhz-mmx processor and the same thing happened. It would only run as 166mhz at a jumper set to 200mhz. Scotty Mac a.k.a smaxted

Could someone help me figure out the reason why the processors are under-clocked and not running at the right speed? Scotty Mac a.k.a smaxted

It is a GigaByte board, this is a link for the manual:

It needs Adobe Acrobat Reader, right-click the name and save it to your hard drive.

set the mobo speed to 60mhz and the multiplier
to 1.5x. The k5 PR120 actuall cpu speed is 90mhz

According to the manual, the switch settings for the AMD K5-P166 are:
SW1 - ON
SW2 - ON
SW3 - OFF
SW4 - OFF

But I am curious as to why the manual specifies the K5-P166 but the CPU is marked K5-PR166.

Sorry, I read your posting wrong.
AMD k5 Pr166 66mhz 1.75x

What is the max multiplier and bus speed that your mobo
can handle?

 

[mainegeek]

Note* The K5 PR166 runs at 116.7 mhz Socket 5,7
The K6 Pr166 runs at 166 mhz Socket 7

The PR rating doesn't always represent the true
cpu speed until you get up into the K6.
