To Milt and Hans,

Thank you guys for your responses. I appreciate your help.

I finished troubleshooting the MB last night and finally found my problem. Here's the breakdown of the process:

1. Tried a new PSU
2. Installed plastic insulators on the MB
3. Set up the MoBo on the anti static foam that came with the board

The reboot after 5 - 20 minutes continued to plague my system. I decided to try one other option:

I installed an ATI AGP 9000 128 graphics card into the AGP slot, set up the BIOS, and booted up.

Result: 24 hours of pure speed. This MoBo really cooks once you have it running. I'm fairly sure that the graphics chip is fscked. I am writing to the distributor from whom I bought the board to see if I can RMA it. Shouldn't be a problem. Damn! 3 Days to troubleshoot a bad video chip. Thanks to the people who took the time to add their thoughtful input on this msg board.

BTW, this also cured my problem with Linux. Runs perfectly. And the speed. Oh, the speed. As soon as the new MoBo arrives, I would like to mod it for overclocking. I'll be speaking--er--typing with you guys soon!

Respect!

You are welcome Matty!

Feels good to help people solve their hardware problems :P
Milt: What did you say about my 235W PSU? Don't forget that, I actually live in south america, Argentina. (220Volts)

Hey people we can make an A7N266-VM community, I love my MOBO! :D

If any1 wants to chat with me,

You might try either removing the Northbridge's passive HS and installing a HS/F from an older K6 or Pentium system, OR, do what I did and just duct tape a small fan to the top of the Northbridge, 'cause that sucker gets HOT!

I also added a small, passive, HS to the southbridge. It gets fairly warm too.

Remember though, I've got my VM overclocked to hell & back...

I was just commenting on the fact that you, like me, are using a low power (relatively low compared compared to some) PSU
Yours is 245 Watts
Mine is 145 Watts

Watts is a measure of POWER. It's the product of Volts x Amps = Watts

Take a look at the sticker on your PSU for'Input amps @ 220 volts' and if yours is 'switchable' from 220 to 120, like most here in North America are, then @ 120 volts you'll find it draws ~ twice the amps.

Check it and LMK... i replied to your PM

Hi,

Can MILT or anyone else give me some help with the solder mod ?

Basically you have to cut that little wire then solder it onto another contact. But which contact do you solder it onto, i have no idea.?

Here's my diagram of it,

1 2 0 0
3 4 0 0
5 6 0 0

Where all 0's are the 100mhz and 133mhz jumper pins, 1,2,3,4,5,6 are soldered dots and the wire is currently connected between 4 and 6

also which BOIS is best to use? I have to 1.005 bios, should i keep that then do the solder mod then thats it ?

Thanks a lot for any help.

Well does anyone have any sugestions on how to get the Audigy sound card to work on this motherboard? I have had no problems with this motherboard other than this one.

Unsolder the little wire that currently connects pins 4 & 6 in your diagram from the backside of the mobo. Heat the wires ends alternately and push it through until you can get a bent paper clip or similar UNDER the loop to help pull it out.
Having two people working together is handy for this step.

You can then reuse the same wire to bridge pins 4 & 2 in your diagram.
But, a much more elegant solution is to install a new 3-pin jumper where the wire was.
By this method you'll have the option of going back to the 'factory' settings, where you use the jumpers to set the 100 or 133 FSB
That's if you have an old 'dead' mobo kicking around that you can get the 3 pins out of.

Sometimes I'm glad that I didn't toss those 'junk' computer parts

I'm sorry but I can't offer you any help with the Audigy on the VM.

But what the hell is wrong with SoundStorm, the on-board 6-chanel Dolby Digital surround sound?
Or did you not get it working?

In 60 years on this planet, it gives me the BEST sound I've ever experienced.
Why waste an excellent sound card by installing it in this mobo???

Joe, keep using your current 1005vm.bin BIOS... it works fine, I'm told 1004 does not, don't know about 1006, but the Asus update thing won't let me go back to 1001, which also works for FSB changes.

I have everything except the CPU to build a system with the Asus A7N266-VM motherboard. What I need is a recommendation for which AMD processor I should use. I'm most interested in stability rather than all out speed. After reading the posts here, I can't tell if the problems people are having with this board are related to the processor or not. Thanks.

I have just (6:00 PM, May 11/2003) purchased one of the latest XP 1700+ T-bred 'B' processors from my local reseller here in Ottawa, Canada, for $89.99 Canadian = $64.75 US.
It has all the correct numbers & letters that I'm looking for, including a '27' where I'd like to see a '27'!

You're looking for an AXDA1700DLT3C, week 10 of 2003 or newer, with '26' (preferably '27') in the last 6 digits of the top line
The sticker should read like this one
[IMG]http://216.38.13.28/Athlon1700'B'DLT3C.gif[/IMG] except be a DLT3C NOT a DUT3C

I'll be back later with a full report, but for now let me say that it boots into WindowsXP, stock, right out of the Retail box, at 11.0x 181 FSB = 1991 MHz, and that's the limit that my Asus A7N266-VM mobo's FSB settings can go up to, even WITH the 'solder mod'

In other words, it's now running at the same CPU speed as an XP 2400+ (2000 MHz) BUT AT A REDUCED VOLTAGE of only 1.5v vCore, where all of the 2200+ to 3000+ need 1.65 vCore to get there!
As I write this it's idling at 38 C, using the stock Retail HS/F

So now, in order to make full use of this fantastic CPU, I will have to modify a brand new processor by cutting a bridge or two with an exacto knife, in order to RAISE the multiplier.

Your motherboard is capable of running one of these T-bred 'B' processors, so GRAB ONE NOW, because production of ALL AMD Athlon XP 1700+ and 1800+ processors has ceased as of late March of 2003.

So get one while you still can...

I know I said T-bred 'B' and the way to tell it's NOT an 'A' (which you DON'T want) is the first string of letters on the bottom line must end in 'B' NOT in 'A'

The link in the above post will work if you copy and paste, and that shows a 'B'

thanks !!

amazingly it worked, even though i seemed severe a track on the board by mistake or i think i did. I just used a lump of pure solder to bridge the the points after cutting the wire with a huge bread knife ...lol ... took about 15mins.

Ive got a duron 1.3 up to 1489 so far with no temp increase, or problems. But the Settings jump from 115 to 133, bit of a pain. I wonder if the 1006 bios changes this? dunno.

Only problem im having is that the OC doesnt stay if i put my 8500le in , only works with the o/b grfxs????? any ideas

Hi
With my mobo. I would like to run it with 133:133 but it keeps restarting (unexpectidly) for some reason. and it works fine with 100:100 but my Athlon XP 1800+ only runs at 1.21ghz instead of 1.57ghz. Milt you seem to be the expert here, you know the problem?

It is infuriating. the temps are...
CPU - 51C
MB - 37C

I know people have more than that so I dont think that will be the problem. Any information please e-mail me at Infrared_raven@msn.com
all help is appreciated...

Your CPU is running awfully hot Lloyd... that's borderline shutdown ( by ME! ) territory.

I like to see mine in the low to mid-40's, no more than that.

Pull the side off your case and set up a small desk fan blowing cool air directly into the box.
See if that helps.

Check this image of my 1700+ @ 2308 MHz... temps AFTER the test phase are 44 C

@Lloyd Thomas

You'll need to find out if your proc is locked, if it is then your probably pushing it too hard at 133.

Its probably locked at say 14x if so your running 14x133 =1862 Mhz without a voltage increase, so hence the reboots becuase your overheating.

unfortunately unlocking doesnt make any diff on this board you will have to MOD the JEN jumper on the board to put it into jumperless mode.

I need help with this unlocking and the jumper thingy as this is the first computer I have made and I am not really up to scratch with all the stuff I can do. Is there any web site that explains it in great detail or can anybody tell me how to do it???

>> Re: HELP!!! ASUS A7N266-VM
well you've got 2 choices here, firstly you could try a high end heatsink/fan if you dont already have one, also you will need top quality pc2100 RAM, or some brand of PC2700. make sure your cpu/memory ratio in the bios is set at 1:1. These things may well allow you to run at the 133 FSb comfortably. also a couple of case fans wouldnt hurt. but you see by the time you do these thing you'd be just as well buying a 2100+, almost.

secondly

If not, you can, as i said before mod the jen jumper which is right infront of the FSB/Memory jumpers by the APG slot. You need to cut that tiny wire that bridges 2 points, then solder 2 other points together, cuting the wire is the hard part. see my diagram above you should be able to work out what it means.

if you want to change the cpu voltage or multipler you will have to MOD the CPU itself with a lead pencil.

You say above "this is the first computer I have made and I am not really up to scratch with all the stuff" so lets just stick to the basics and get you running properly at the factory settings for your Athlon XP 1800+ first, and worry about the fancy stuff later okay?

" I would like to run it with 133:133 but it keeps restarting (unexpectidly) for some reason. and it works fine with 100:100 but my Athlon XP 1800+ only runs at 1.21ghz instead of 1.57ghz"

Your 1800+ has a 'fixed' internal multiplier of 11.5x times the standard 133.3 FSB (FrontSideBus) = 1533MHz.
But it doesn't want to run at this speed because it gets too hot and 'BlueScreens' on you, or causes a reboot.
At a slightly slower speed of 11.5x 100/100 = 1150 MHz it runs a little cooler, so it's okay.

You NEED to get your CPU temp DOWN first. 51 C is just too hot for reliable operation.

When you installed it, did you use the Heatsink/Fan that comes with the Retail version of the 1800+, or some aftermarket HS/F?
If the former, did you peel the clear tape off the bottom of the HS/F before installing it?
If the latter, did you use a good quality, THIN LAYER of ArticSilver III, or similar, Thermal Compound?

If no to either of the above questions, there's your problem.

And, I'll say again, in case you missed it the first time...
Pull the side off your case and set up a small desk fan blowing cool air directly into the box.
See if that helps.
