View Full Version : AMD Athlon 3200+ 333FSB on a KM400A-8237 board
I recently purchased a new AMD Athlon XP 3200+ 333FSB Socket A (Socket 462) processor from eBay, model AXDA3200DKV4D. This processor was apparently only used on Hewlett Packard d325 desktop computer systems which used an nForce2 chipset. I have also read on the web that the processor works with an AK77-600 MAX motherboard. This processor is different from the Athlon XP 3200+ 400FSB processor, AXDA3200DKV4E. The Athlon XP 3200+ 333FSB processor runs at approximately 2333Mhz with a clock multiplier of 14 x 166Mhz. The problem for me is that I have a Biostar M7VIZ400 motherboard with a VIA KM400A-8237 chipset which uses Phoenix BIOS 6.00 PG, dated 11/9/2004. The BIOS does not let me manually set the clock multiplier. The computer does not even power on when I have the Athlon XP 3200+ 333FSB installed. The power LED becomes orange when it is normally green. The computer runs fine with an AMD Sempron 3000+ processor. I like using the RAID 0 feature of the 8237 Southbridge, so any replacement board would have to have RAID capability. I already have the latest BIOS that is available for the M7VIZ 400 motherboard from the Biostar web site. I found out after I purchased the processor that the motherboard only supports processors up to the AMD Athlon XP 3000+. Is there some other BIOS that I can use or some other VIA motherboard that I could use with the Athlon XP 3200+ processor?

AMD Athlon XP 3200+ 333FSB Socket A (Socket 462) processor from eBay, model AXDA3200DKV4D. This processor was apparently only used on Hewlett Packard d325 desktop computer systems which used an nForce2 chipset.This was a contract OEM part, never released publicly or to channel partners by AMD. I would have guessed it should work in your board, given that it supports Barton (Model 10) up to XP3000+ and 333MHz FSB, assuming that you didn't get a defective CPU. Have you tried clearing/resetting the CMOS?
No, I haven't tried resetting the CMOS. Shouldn't the computer automatically detect what kind of processor is installed? I am really hoping for a BIOS update that would allow me to use the Athlon XP 3200+ 333FSB processor. If I knew what bits to modify in the BIOS update image to recognize the new processor, I could do it.

This really has nothing to do with the chipset.

you can updtae your bios. there are 2 ver. Number two your motherboard. make sure you cet the right one.
1 - M7VIZ (http://www.biostar-usa.com/mbdownloads.asp?model=m7viz)
For PCB v5.x only! Corrected the problem where CPU speed is not properly identified with Thorton processors. Without Biostar splash screen.
2 - M7VIZ V8.X (http://www.biostar-usa.com/mbdownloads.asp?model=m7viz+v8.x)

thorton cores are useless....

you can update your bios. there are 2 ver. Number two your motherboard. make sure you cet the right one. M7VIZ is a different model and BIOS from M7VIZ 400. The latest BIOS for M7VIZ 400 has the latest release date of the M7VIZ line, which he already has.
The Thorton update for M7VIZ (different model) was misreported speed issue, but the processor runs fine. He is reporting a no-POST issue.

MY BAD Misunderstod..........
Thanks for trying to help, anyway. I had already sent an email message to Biostar indicating that my Athlon 3200+ 333FSB processor did not work with my motherboard and was hoping that someone here could help me. I received a reply from Biostar today: "correct, MVIZ 400 does not support 3200+ processor, maximum is 3000+333." Well, that was not very helpful.
I did find a BIOS update on a Russian site called ROM.by. It is not for the faint of heart, though. Most of the links are dead on the English page, so you have to go to the Russian pages to download the appropriate files. I had to download a program called awdflash.exe from a different web site. Its use is described on this web site:
I downloaded the latest version of awdflash.exe from the web site:
I was then able to create an MSDOS boot disk and save a copy of the existing BIOS with the command:
awdflash a:bios.bin /sy /pn
The floppy disk did not have enough space to patch the BIOS there, so I rebooted from the C: drive and copied the BIOS.BIN image to the C: drive and ran BP-4_23.EXE from the command line to patch the BIOS. I had to have LHA.EXE and CBROM.EXE (from the CBROM215.RAR archive) in the same directory. I then copied the patched BIOS.BIN to the floppy disk, rebooted from the floppy disk, then executed awdflash.exe again to flash the BIOS with the modified BIOS.BIN file.
The BP-4_23.EXE program seemed to indicate that it was adding support for more processors to the BIOS, but I was still unable to use the Athlon 3200+ 333FSB processor afterwards. The program also indicated it was making some other corrections, like locking the AGP bus speed, so perhaps this adventure was not a total loss. I was able to increase the FSB frequency from 166 to 177 with my Sempron 3000+ processor.

But they can be modded into Barton, if I am right..?
The Wikipedia entry at:
indicates, "The Thorton core was a variant of the Barton with half of the L2 cache disabled and thus functionally identical to the Thoroughbred B core. The disabled L2 cache on some Thortons was partially defective, but on others it could be re-enabled through bridge modifications."
