I have an Atlhon 1.4, Asus A7M266 M/B, 256MB PC-2100 DDR, On-Board Audio, 64M Ge-Force 3 Ti500 (Hercules).
I just built this thing and the problem i am having is with installing windows, if i drop the FSB back to 100Mhz everythink works fine but obviously i dont want to do that i want to have it running at 133 or higher
The only things i can think of is that i either have a faulty Motherboard, RAM or CPU, i dont know if blue screen errors actually tell you what piece of harware is at fault but i'll give you the Blue Screen message just in case it does and someone out there understands it.
"A fatal exception OE has occured at 0028:FF037A60 in VXD"
"HIDCLASS(01) + 00000F40. The current application will be terminated..."
so on and so forth with its regular message.
This happens during the windows install and im stuffed if i know whats wrong.
You might be thining oh well install at 100 FSB then clock it up to 133, but the trouble is i have heaps of problems in windows at 133 also.
This is probably one of two issues: either a memory problem, where you're memory is unable to run at 133MHz(266MHz DDR), or merely a simple IRQ conflict which can be safely ignored 'til after the installation finishes. Does setup continue after BSOD?

>><i>By factory default, the A7M266 is jumpered over pins 1-2, resulting in a DIMM voltage of 2.8V which causes performance deterioration in most high performance DIMMs. The standard DDR operating voltage can easily be restored by simply removing the jumper.</i>
:smile: Good or Bad have no meaning at all, depends on what your point of view is.
I'd better correct that info about the jumpers and RAM voltage.
First - I believe factory default is 2.7V. (not that this matters much)
Second - The manual puts the jumper diagrams upside down. This means that the orientation in the manual will confuse you. Pin 1 as I recall is towards the top of the motherboard (when it is installed in the case).
Third - and MOST IMPORTANTLY! Pulling the jumper results in a voltage of 2.8V (not 2.5V). The A7M266 only supports voltages between 2.7 and 2.9. Many people have found that by Increasing their voltage they get more stability. (not just RAM voltage - VIO1, but also on VIO)
Over at amdmb.com a couple of people measured the voltage to confirm it is 2.8V with the jumper pulled.

Ok in response to all those ideas.
1. I have allready removed the VI/01 jumper to put the RAM voltage back at 2.5 what it should be.
2. My ram is not faulty as i have tried my friends Kingmax PC-2700/333Mhz DDR Ram and it does the same thing.
3. I am assuming i have a 133 Mhz Athlon VPU as it is multiplier locked at 10.5 and the only way to get it up to 1.4Ghz is with a 133Mhz system bus.
4. I have tried the ram in both of the slots on the motherboard and the same error occurs. The error appears in the part of the windows install where it detects hardware but i have tried all different hardware wiht no change, different Videocard, Soundcard, Network Card etc.
OK, so Id think you are left with either a heat issue (not likely if you are using approved hsf, esp from retail box) or a power issue. Make sure you are using a quality power supply and the power in your house/building is clean (ups can test for clean house power).....
Ok the problem has been found and it is my motherboard, i tried my friends asus a7a266 Motherboard and my compouter ran perfectly, no errors on Windows install and so-far no errors actually in windows. So my question is, as my friend wants his motherboard back what MOtherboard is the best one to buy.
