A7N8X Deluxe detected wrong processor possibly??

[deanhiller1]

I just put together a new computer specifically having these components
1. A7N8X Delux
2. CPU AMD 2200+/266 Athlon XP
3. DDRAM256M PC-2700 DDR333VS CORSAIR
When I boot my PC, it says the cpu clock frequency is 1350MHz when an athlon 2200 should be running at 1800MHz. I started fooling around by changing the CPU External frequency. change that to 166(since the FSB is supposed to be equal to 2 times this). I figure I should be operating at a 333 MHz bus speed with this processor and RAM. Then windows tells me I have a Athlon 2800. I don't want to overclock my processor right now. I just want the normal output. I also read the default for the A7N8X was to run at a 333MHz speed, not 200MHz. Why is mine starting at 200MHz? Maybe I am just confused. Does setting the CPU External Frequency set the bus speed? I assumed it does, but then winXP thinks its an athlon 2800. Also, how in the world do I slow the bios down? I keep hitting pause break and space bar, but would rather now how to have it go slowly by instead of screaming by because I see other possible things that don't make sense and I want to investigate them.
thanks for any help on this
very frustrated,
Dean

Well it looke like that you are only runing at 100 FSB on tehe chip right now and that chip only support 133 fsb. 166 would cause major problem usless you crank the voltage up there which would fry the chip without good cooling. Changing the clock cycle of the chip will change the FSB settings of the ram. The Mobo is trying to sync the FSB of ram with the FSB of the chip. Your ram is 166 which the mobo is trying to push the cpu to 166 (166 x 13.5 = 2241mhz) wich would make it a xp 2800 in t-bred since. My advice is to a cpu that fully supports 166 clock cycles like the barton 2500.

No coincidencei suppose, but i'm having the same problem. I picked up a 2700+ athlon xp and my a7n8x deluxe is detected it at bootup at 1100 mhz. Is it detected it wrong? I read on their website that it supports 600~3000+ a socket chips but then looking at the manual it says athlon 3000+. Is it possible i'm using to old a chip and it's detected it wrong because of this?

To above poster.. sorry couldn't help man but i figured might as well condense the problems into one post.

dean dude don't listen to that last poster telling you to "buy a barton to solve your 133FSB problem."

In the bios under either advanced chipset options or something like that you should find the CPU FSB setting. Change it to 133. Then look for the CPU/DRAM or FSB/DRAM setting or something similar and change it until it gives you either a 166 MHZ or 333mhz resulting frequency(depending on how it reads). Also read the manual and find out if there is a Jumper on that motherboard that puts the board in a "SAFE" mode that boots with 100MHZ. If there is change it to whatever the other setting is and it should work for you.

What has happened is that you are overclocking your 2200+ to 2800+ speeds by running the FSB @ 166. If it did this without you raising the voltage and was stable in windows, consider yourself very lucky. My 2200+ stopped at 160MHZ FSB. All of that aside though make sure to watch the cpu temps.

Just a computer junky

change the fsb to 133 is the correct solution, when board get erros or when bought new, the <font color=blue> default </font color=blue> fsb is 100... (my Xp2000 would run @ 1250Mhz under fsb 100)

Trust me I know what I'm doing... ooops, grab the cat...

Just a quick point... A T-bred 'B' core Athlon can <b>easily</b> cope with 166Mhz FSB, and the fact it booted at all at 166 would suggest it IS a T-bred 'B'. Other than that you are right though.

Common mistake, your chip is a "266MHz" bus processor, but...there is no such thing. It's actually a 133MHz bus. AMD invented the lie, Intel felt compelled by it's success to coppy the lie, and so the lie lives.

So as others have mentioned, your CPU is running at 100MHz bus and is supposed to be running at 133MHz bus. 166MHz bus would be overclocking the CPU quite a bit and wouldn't work at stock voltage (and probably not without extreme cooling anyway).

that chip could take 166mhz fsb @ stock voltage...if its a tbred B

There is no smell better than fried silicon

hi.
I think decreasing multiplyer is better.if it's a thoroghbred "b" so the best setting would be10*2000@stock voltage.Do not exceed 60 degrees celsius.

u haft to flash/update the bios to 1005... my 2500 barton on the SAME board was onyl recognized at 1100MHZ.. did the bios and its fixed...this was only like 3 days ago..so try that before u haft to go messin with settings!
