Alex,

Did you upgrade any drivers, install new software, or add something to your computer?

Joe

OT - Aldrums, we are using the same mother boards. I had a similar problem when I first set this system up. I can't say that it was exactly the same problem, though, as I didn't record the error message. I had fiddled with the memory parameters in the BIOS, as I always do. :) I set it back to the default ("by SPD") and haven't had the problem since. I think that I thought I was setting the CAS latency, but was actually fiddling with something else.

You should make sure that you are using QUALITY memory with SPD (serial presence detect) and ECC (if you are willing to pay the substantial premium for ECC). Be aware that MANY cheapie DIMMs have SPD ROMs that "lie", though! The SPD ROM is a small ROM on the DIMM that contains all of the timing parameters. A modern mother board will read-out the SPD ROM and set the timings accordingly. But some of the cheapies burn the SPD ROM with incorrect parameters, so that the mother board will actually run the DIMMs beyond specs. For example, in some cases they will buy PC100 chips and burn the SPD claiming it is PC133, knowing that in most cases it will work OK.

If you stick with the major name brands, it is unlikely you will have this problem. But be careful about "major name brands". Some unscrupulous memory vendors will sell "Toshiba" DIMMs, for example, where only the CHIPS are made by Toshiba, and the DIMM assembly itself is made by some fly-by-night operation.

For memory testing I use memtest86:

reality.sgi.com

It is stand-alone - you make a floppy which actually contains a small Linux kernal. (Nope, you don't even need DOS - they give you a program to make the floppy). memtest86 was able to demonstrate the problem that I had with the improper settings. Do give it a chance to run, it may not find problems right away. You probably don't really need the more exotic (over-night) tests. In my case, at least, it was able to get to a failure case within a few minutes.

Re: Help! I am running dual Pentium III 733 MHz flip chip processors

The stop @ address can sometimes be used to diagnose problems by reviewing the list of loaded drivers that appears below the stop error. The list will include load addresses that will let you (sometimes) determine which driver caused the error. Then update that driver, or replace the offending component with a different model if it's something replaceable like a network card - which will use an entirely different driver. And if the component is at fault, you'll have replaced that, too.

Good Luck,

Dan
