Athlon Xp 2800+

I had a question about my PC. When I go into my BIOS it says my processors operating frequency is Athlon XP 2800+ but when I look at the multiplier factor it says its 12.5 (thus right now my PC is telling me my processor runs at 1250 MHZ). Why does SiSoftSandra say there is a Athlon XP 2800+ that runs at a speed of 2.03 GHZ? and should i change my multiplier factor in my bios to be 20 so that its 100X20 or 2000 MHZ like it should be? or is that dangerous and could it damage my chip?

I remember months ago seeing in my computer > properties that it said Athlon XP 2800+ at 2.03 GHZ but now it says 12.3 GHZ

Is my Prcoessor's full potential not being recognized b/c of my motherboard?

Do I need to change a setting in the bios?

When compared to the Athlon Xp 2800+ in SISOFT sandra -- my processor (2800+ as well) does a little more than half the potential of the Xp 2800+ 2.03 ghz processor that Sisoft Sandra has in its selection of benchmark comparisons.

Why isnt my Athlon Xp 2800+ performing on par with the one SIsoftSandra has in its comparison choices?

Should i change the multiplier factor in my bios or can this damage the motherboard and processor?

Right now the multiplier factor is set at 12.5

Im using a ABIT NF7-S version 2.0 -- will that support 166 FSB?

In my bios i looked more closely -- It says:

Cpu External Clock : 166mhz
Mult factor: x12.5

At the top of that same screen it has:

CPU internal frequency: 1250mhz (100x12.5)

for some reason it registers my CPU's fsb is 166 but its running it at 100-- I dont know how to make it run my CPU at 166 fsb.

cpu interface is currently at "enabled" and it still has the external clock at 166mhz, but its internal frequency is 100mhz x12.5 (1250mhz)

It wont let me change the internal frequency for some reason --

External Frequency only goes from 100 to 300 mhz -- I didnt see syncronise as an option for external frequency.

The FSB to ram ratio is set to AUTO but it can be changed to SPD

basically the only figures I can change are the External frequency and the Multiplier factor.
the internal frequency is not highlighter . it just states 1250mhz (100x12.5)

I wouldn't update the BIOS yet. That should be last ditch. You could check and see what they fixed with the updates and if your problem is listed in the fixes, then go for it.

When you said that the CPU interface was enabled, did you change it to that, or was it already enabled? If it was you that enabled it, did you exit the BIOS and save the changes?

what kind of RAM do you and what speed is it?

I am not sure waht to do here, any more assistance would be great

Go to 'BIOS setup', if you see 'CPU operating setting' is 2800+, then press F10 to save it. It will restart and run as that speed.
It always works for me as for some reasons my mobo changes to to Safe mode (I also have Abit NF7-S both rev 1 and 2.0)

Something you might want to check into, my aopen mobo had an fsb jumper that I had to manually change from 100,133,166,200. Check to see if your mobo has this option. I know this doesnt seen right during this day and age of auto-detecting FSB but just look into it. This aopen had an kt800 <Last of the socket A boards>.

To all of you with problems:

Go here.

Download, install, run.

Post screen shot or tell us what your results are.

I had exactly the same thing happen once, same CPU, same speed. Perhaps there is a jumper on the motherboard limiting to 100mhz?

Meh, I don't get why this happens.

Alright....this thread is all hacked up!! The first guy was right about windows taking a dump. The dude who mentioned a BIOS flash is pre-emptive. You bios does not support crash recovery and so even though one screen still says 166 it in fact has defaulted (as the other guy said). Your board does in fact support a 400 fsb but if you do not have a Barton core on the XP 2800+ then I would not set it that high (i.e. 200). If you have the thoroughbred core then you should set it to 133 thus making it an effective 266 fsb. What you should do is reset your bios using the jumper. You have to pop out the battery and then move the jumper from its park position. Obviously you should unplug your power supply before you do this. Wait for a few seconds for the capacitors to discharge and then put the battery back in and move the jumper back to its park position. You BIOS will be completly reset including time and all other settings so don't worry. You next have to just go in a manually reset everything. I reccomend only making 3-4 changes at a time and then reboot and change more settings because some boards don't like it when you change everything at once. Find out which core you have on that (Barton core or not?) and go from there.
