Title: CPU detection problem
Post by: Aaron on August 19, 2003, 15:30

Hi! I bought an Asrock k7s8x motherboard along with an amd xp 2400+ cpu but even with the bios updates the bios detects the chip as 1800+  You cannot change the settings at all it is all automated.  Any ideas? Thanks Aaron

Hi Aaron,According to this review of your mobo :

http://www.ocworkbench.com/2003/asrock/k7s8xe/k7s8xegallery3.htm

It says :
There are two jumpers for selecting the default FSB of 100, 133,166,200

Also :
The CPU Host Frequency can be set to AUTO (based on jumpers on board) or set Manually. In Manual mode, the FSB can be set from 100~248 at 1MHz stepping.

So I would suspect that you have the jumpers set for the wrong FSB and then also set at AUTO.
Check your manual for the relevant jumpers and their settings and I think you will be able to run at max speed once you have reset them :doggie:

On the same review it says in the conclusion :

Anyway, the board does provide a FSB of up to 248MHz which you can select. With no voltage tweaks, the maximum FSB I can get the board to run steadily using relaxed timings without any modifications is 208Mhz. I have seen the board POST at 218MHz but hangs in a blue screen. That shows the potential if you intend to do the mods to the board.

I hope this helps you  :-*

Just in case you are quite new to PC's Aaron, here is how it works:

Your CPU has an inbuilt speed.
Your motherboard has a speed too.

The CPU 'clock' speed is for example .... 14x
The Mainboard 'FSB' speed is i.e. ....... 166Mhz

so 14 x 166Mhz = 2324Mhz (or 2.4Ghz if you like - its close enough).

-but- if your mainboard is not set up correctly, and is set at 133Mhz then you get

14 x 133Mhz = 1862Mhz (or 1.8Ghz if you like).


So you can see from the same CPU and a small mainboard setting wrong - you can decrease the speed of youor chip!
