Soyo SY-K7VTA Pro V1.0 thinks my Athlon XP 2600+ is a Duron

[Don]

The mobo docs say it supports the 2600+, but even with the latest BIOS it thinks it's a Duron. Setting the FSB jumper to 133, and multiplier jumper to auto, then the BIOS gets set to "default", which means multiplier is the minimum (5) which gives 667 for total CPU clock speed. Setting multiplier jumper to manual and the dip switches to the board's max of 12.5, it doesn't say "Duron" or "Athlon", but it just calls it a "2000+" using total CPU speed of 1667 (133 * 12.5). (Which begs the question of how the board can support the 2600+ as advertised when the max manual multiplier switch setting on the board is only 12.5.) The white printing on the CPU's PCB is stamped with AXDA2600DKV3C, but I never wrote down the stepping code before I put the heat sync on. CPUID gives report of 681, but cache is only 64K, which is probably why the BIOS thinks it's the Applebred Duron. CPUID does return "AuthenticAMD" Why does it say AXDA2600DKV3C, but CPUID only returns 64K for cache? Is it a Duron that's been faked as an XP? I know the board and CPU are obsolete but I like this old stuff. Bios upgraded to the most recent. Oh, one more thing. Even when set to the 1667 (2000+) setting, Everest measured the CPU very poorly -- not anywhere near my DFI board running an Athlon XP 1600+. I have 3 sticks of Viking 256M PC 133 memory running at 133Mhz, latency of 3. HD only runs at ATA100 for now. But the CPU benchmard doesn't use the HD anyway.

Because if set on auto, the multiplier is selected correctly (you get 16x).

If you talk about L2 cache, it's a duron.

Could be a fake. If you have time take a few good pics and post them.

Yes, that's L2 cache. The processor chip itself has no ID printed on it; the ID is white printed on the processors PCB. CPUID instruction returns 64K for both L1 and L1 cache. The only thing that was 256K was something about TLB. If mobo jumper is set to auto, multiplier becomes 5 (which is the minimum for the board.) I'm going to replace it with an XP 2000+, which uses FSB 266 and mult 12.5, so I think the board will like it. Then I'll take pictures of this so-called 2600+ and post them. For now I'm exploring the mystical world of multi-booting with 3 hard drives: one with 98SE, the next with WinXP, and the other with UBUNTU Linux. I did 98SE OK, then I did Linux. The BRUB does the boot loader function. So now when I do WinXP what will happen to the GRUB? All my computers have 2-drive, 98SE/XP setup. I did this one differently because I just got the UBUNTU. I couldn't wait to try it, so I did it prior to doing the WinXP. Once I get it right I'll add UBUNTU to all my computers. (I have 7 computers).

I got the CPU from someone on ebay. It was advertized as an Athlon XP 2600+ for FSB = 266. All CPU ID tools thought it was a Duron. After all, they are both CPUID = 681. But Duron has L1 and L2 cache = 64K. CPUID tools showed this one had this and so they thought it was a Duron. Also, benchmarks showed performance in the Duron range; not the Athlon range. My mobo is a KT133A chipset. It has auto settings or manual settings. Auto setting set the multiplier to the default of the lowest for the board = 5. Manual has max multiplier of 12.5 which gave speen equal to an Athlon XP 2000+. So in no way could it operate as a 2600+. The mobo is advertised to support the 2600+. I removed the processor and put in a 2000+. The mobo recognizes it correctly on both auto and manual and benchmarks show it to perform in the Athlon 2000+ range. On the so-called 2600+ there is no IDs printed on the actual CPU die. I earlier said the info was stamped in white onto the processor's PCB. Not true. The info is printed on a plastic sticky lable. It says AXDA2600DKV3C, stepping code JIUHB. I didn't peel off the label to see what's underneath. The CPU die is not sized like any other Athlon XP in my posession. It is more rectangular. Adding it all up I'm tempted to think it really is a Duron that's been faked as an Athlon. I'd attach some pictures but I don't see how to do that as a guest to this BB.. I see an "img" button that gives this: [img][/img] , but the images are on my PC; not on the web anywhere. How do I insert an image?

You ahve to register or go to photo shack or similar and add links here.

Go to ubuntu site browse for your issue, it's easy, you start the ubuntu cd after you installed the xp OS, running grub will write the boot sector.
Easy stuff, believe me.

If you resize partitions or add partitions, or delte partitions, the hd partitons will change name for ubuntu, resulting an unoperable system, you'll need to write the ubuntu grub boot sector again, I tell you this before you think ubuntu fxcked your system OSs. If ypu have XP on a different HD, you'll just need to write a few lines in a grub config file, go to ubuntu and look.


All you have to do is look for Grub and how to repair it.


Linux is different, not impossible. I started with curses and now I play with different distros, have fun.
