Why do you believe the clock speed to be the problem ?
Or more specificly, what exactly IS the problem ?
I had a AMD XP 1400+ (or whatever) that ran @ 1.2ghz by default. I was able to use it in Mandrake 10 on an Asus A7N8X at clock speeds from 1.2ghz to 1.99 Ghz with no troubles.

1.
As a stated I can't get a clock speed above 1700 , if I select I need a reboot and machine opens the bios and says there is something wrong with the speed.
Default it runs only 1100.
2.
Can't get the voltage below 1.75 even if the jumper is in the right position.
I do not see a BIOS version 1011 for your motherboard at ASUS site. Pick either motherboard that does not have an OS installed. Then flash its BIOS with 1010_X. It should not have any problems if you do not have an OS installed although Linux does not care about the BIOS version.
BTW, the ABIT NF7-S2 is a lot better motherboard than ASUS A7V8X-X and it is designed for the Sempron.

Isn't this a hardware related forum ?
I can't install any os as long as the mobo does not function.
Do you assume I didn't look at the Asus site? I can also read, my mobo has I bios version 1011.
Are you seriously suggesting, that I should load a lower version Bios?
Please learn me and a lot of people how you install linux if the mobo does not start up. I thought I know something about mobo's and linux, but this is new to me................
It doesn't interest me at all if Abit is better, I think there will be at least half a dozen mobo's better than your Abit! If you do not have answers, than do not answer!
My questions where very simple :
1 Did I specify the right clock speed. Obviously I didn't.
2 Has anyone else problems with the power setting of this Assus mobo.
If you use Abit, that is fine, but you can't help me on the last question......................
Originally posted by Electro Yes, but your issue is not Linux. Your problem is general which should go in the general forum.
The Vcore should b set at 1.6 volts. The FSB multiplier should be at 10.5. This information is for model 8 of Semprons.
I do not know how you got the 1011 BIOS version.
I didn't see any intervention from the moderators so....... I do not agree.
Yes I know the Vcore should be set at 1.6 but that is not possible (see first posting and several replies....)
Yes the multiplier should be at 10.5 at 163/33 but that does not work (see previous postings).
Thanks anyway for your reply and all the other replies. I got the info from AMD (thanks kak), as I said I can live with 1700 but i was worried more about the Vcore .
Starting off, by looking at this page, you'll realize why your computer is not recognizing the sempron correctly. You need at least BIOS version 1012 for sempron to be supported:
And get the 1013 BIOS version. That's the latest official BIOS although there's also a 1014 beta BIOS out. During my time with a P4P800D, I tried beta BIOSes but they never seemed to offer anything different and the fact that betas are not necessarily stable brought me back to official BIOSes. Then flash the 1013 BIOS and you should have sempron support. Even the release notes for both 1012 and 1013 bios versions state that they include more CPU compatability so yeah....
Ok, I'm not too familiar with the Socket A platform (used S478 and currently S754). In any case, the first thing to do is find out what clock speed your CPU is supposed to run at. If that newegg specs page is to be trusted, then 1.75GHz should be what it's running at. So that should be 10.5 x 166MHz FSB. Now if you actually have a AthlonXP 2500+ and not a Sempron 2500+, then the 1833MHz speed makes sense since AXP 2500+ are bartons running at 1833MHz with a 11 multiplier. Therefore as does the 1100MHz that you're saying it's currently running at. Instead of running at 166MHz, your BIOS has it set at 100MHz FSB. So it should be a matter of changing the FSB from 100MHz to 166MHz. Make sure your RAM can take that speed. If not, you'll need to put in a FSB:RAM divider lower than the 1:1 usually used.
As for your core voltage, I worked on your mobo for a friend at one point and the overvoltage jumper actually does nothing for the actual values for voltages in the BIOS. However, IIRC the overvoltage jumper just adds .2V on top of what you select in the BIOS. Therefore, 1.85V would turn into 2.05V even though the BIOS doesn't have an option for 2.05V. Just remember that. You should not have the overvolt jumper set. It should be at default as the Sempron doesn't need that high of voltages. Unless you're overclocking that is. Then you'll probably want better than just stock cooling.
I'm thinking that the base of your problems comes from the fact that BIOS version 1011 that you say you're currently running does not support Semprons. Update to 1012 at the very least.
Dind't read the responses, so someone may have answered this but the SEMPRONS do not run at the same clock speed as the Athlon XPs. The Sempron 2500+ runs at 1750MHz.
