First off, use your A7N8X Deluxe User's Manual...
Look at the "Advanced Chipset Features" in chapter 4:BIOS Setup, section 4.4.2 or look at page 55. Providing you have the same book as me. Next, here will tell you everything about what to do and how to adjust everything with the chipset i.e. CPU External Frequency (MHz) 166, CPU Multiplier 11x, and many other things. Also go to Google.com and type in your problem and search. 9 out of 10 you will get a responce to your questions.
P.S. Everytime you save something in your bios, and or you turn on your computer, always press and hold the TAB key.
GOOD LUCK

Ok....heres my problem...i have a Mach Speed V400DBL motherboard and a ATHLON 2500 barton chip...but my problem is the same as somebody who posted previously with the chip only showing up as a 1100 and once as a 1900+ this is frustrating the crap outa me..i went to update the BIOS but it informed me that i already have the newest BIOS...so what do i do...

PLEASE help...I have been racking my brain for hours...and tryin all different types of bus speed and multipliers and cant seem to get it to recognize the chip...

Anybody!

BTW, my A7N8X Deluxe 2.0 and 3Dmark2001SE seconizes my 2500+ as a duron 1.83GHz.



Set the settings in your BIOS

well, most motherboard will come with jumper setting for fsb 100 ( like the GA-7N400L that i have) this is so you dont burn up the amd thats not the barton core.

look in your manual for the jumper setting for the fsb ON THE MOTHERBOARD ( mine will be set it to AUTO which will allow the bios to do nasty thing to the CPU )

once the jumper setting is done, go to the bios and select the FSB TO 166 (which gives the dual channel 333 i guess)

i have an AMD Athlon XP 2500 barton 333, when i set it to 11x166 it wont boot, when i set it to 11x133 it boots saying its a 1700xp @ 1.466 mobo is ecs k7s5a pro

any help would be appreciated
Jeff

To run it at 166 you also need pc2700 ram, make sure u have that.

yup, i already put in a pc2700 256mb ddr dimm, but i have read of other problems with this mobo running with one ddr dimm, do you think i should add another?

ffej-
A K7S5A wasn't designed to run with a FSB higher that 150. And that's with a HoneyX or Cheapoman BIOS. You can't run a Barton or any other processor with a 333MHz FSB.

in the manual it says the max processor is 2600+ with fsb of 266, i know the barton has fsb of 333, is there a way to underclock it to 266?

you could do 133x14, but my 2500+ multiplyer could only go to 12.5. anything higher, no boot... 133x12.5=1666 =2000+ speeds

The 2500+ came out after the K7S5Apro did. And I don't see a BIOS update to include it. So your BIOS isn't going to identify it properly. If you want to run that processor at 266MHz FSB you'll need the HoneyX BIOS. You MIGHT be able to run it at ~300MHz (150). But the SiS 735 chipset becomes unstable and overheats around that speed.

That's all these folks do is mess around with this board. I have one in one of my systems and I love it.

I just swapped the 2500 barton for a friends 1800, his puter is happy with the 333fsb and it works fine there, when i upgrade my mobo well trade back

ffeJ-

Good idea.

For the very First Reply the System may be underclocked

Overclock it.
Save to Cmos, When the computer restarts, right away, press and hold the tab button, to enable Duel Channel DDR

Do it.

Did you overclock the CPU?
Anyway, check out this cool In Your Face AMD Website

Does any one know anything about the Albatron KX400 +Pro MOBO?
I installed a 2500xp Barton 333. I can get it to run when BIOS are set up, but It locks up after A while seems to run ok if I leave the BIOS at Default, 133FSB 266DDR Speed and 11.5. If I set it up it does see the Processor as a 1.83GHz, But locks UP. I do have 1GB PC2700

Richard-

You need BIOS R1.06 to run a Barton on that board. You can get it here:
http://www.albatron.com.tw/english/it/mb/bios.asp?pro_id=33

Then you want to set your CPU Frequency Jumper to pins 3-4 for a 166MHz FSB. And while you're there, enabble OTP (Over Temperature Protection) by setting the jumper to pins 2-3.
If you have SW1 (CPU Ratio Select Switch) then set it properly to an 11X multiplier by moving them all to ( - ).
Now go into BIOS and Advanced Cipset Features> Dram Clock/ Drive Control> Dram Timing, and set your memory to SPD.
Now check your processor in Frequency/ Voltage Control> Cpu Ratio, make sure it's at 11X. An your CPU clock should be 166 MHz.
You should be good to go now.

Josh - Thanks for the Info, I tried to update the BIOS, but for some reason I all ways get a "Can't find Source File" error. I tried the other 333 BIOS updates at Albatron's web site also ... Same error. It comes up as soon as I answer "No" to "Do You Want to Save BIOS" (old BIOS).

Doh, anyways, if the BIOS update and the BIOS settings dont work youll need a newer board.The only other possible alternative is to maybe play with the CPU core voltage, but be careful cuz that can fry yer baby!Although it may allow you to boot yer older board with a higher FSB and multiplier setting........This i would see as a band aid to keep you chugging until you get a new board. Visit http://www.buyxtremegear.com and get yerself a nice MSI nforce 2 board for 80 bucks. **note to self** always knew there was a reason i didnt like the word "albatron".............
