Changed CPU’s from a AMD Athlon XP 1700+ to a AMD Athlon XP 2600+
Core Speed 1460 MHz from a AMD Athlon XP 1700+
Core Speed 1659 MHz from a AMD Athlon XP 2600+
In the bios changed from 100/100MHz to 133/133MHz, thought that there would be a much greater increase in the core speed?

Also after changing the CPU’s and starting the system, it went to CHKDSK automatically, something that it hasn’t done before and stated that it was ‘deleting corrupt attribute record (128 “”)’ and listed several and also ‘correcting error in Index $I30 for file xxxxxx’ and listed several as well.
Now when I do my systems I set them up and ghost them so that I can format once in a while and reload everything easily, but it was under the other CPU which I wouldn’t think would make a difference?
Thank you.

I would also like to add that AMD Athlon XP 2600+ is only showing up as an AMD Athlon XP 2000+???

Does you Motherboard Support the XP 2600+ ?

Which flavour of XP 2600+ have you got ?

http://en.wikipedia.org/wiki/Athlon_xp

"Athlon XP 2600+ is only showing up as an AMD Athlon XP 2000+???"

That's because you didn't raise the CPU frequency enough. There are several versions of the 2600+. Only one runs at 133MHz...the others run at 166MHz.

My guess is you have an AXDA2600DKV3D which is supposed to be clocked at 2083MHz (12.5 x 166MHz). By setting the freq to 133MHz, the CPU is clocked at 1667MHz (12.5 x 133MHz). That's the same clock speed as the 2000+. Your board probably underclocks slightly & the freq is actually running at something like 132.75MHz, that would explain why it's at 1659MHz. Do you have CPU-Z? If so, run it & check your clock settings, especially the multiplier. If you don't have it, get it!

As for your file corruption problem - if what I suspect is correct, your CPU isn't supported by your motherboard & all bets are off. Reloading Windows isn't gonna help. Pull the 2600+ & go back to the 1700+.

Go to the motherboard manufacturer's website, check the CPU Support list for your model, then buy a CPU that will actually work with your board.

BTW, are you asking about an ECS K7S5A? The highest supported CPU is the 2600+ but it MUST be the 133MHz (266MHz FSB) version.

Here's a decent site about your board:

http://www.ocworkbench.com/2002/ecs...

ECS K7S5a and is supposed to support the AMD Athlon T-Bred 2600+/ 266 FSB CPU as a matter of fact thats as much CPU as it is supposed to be able to handle.
Once the CHK DSK ran through its scan everything was fine and it didnt run anymore.
The only settings that I am finding in the Bios concerning the CPU speed is either 100/100 or 133/133 with some variations, but no other selections seem to be available, since my FSB is 266 I guess thats it then.

"ECS K7S5a and is supposed to support the AMD Athlon T-Bred 2600+/ 266 FSB CPU as a matter of fact thats as much CPU as it is supposed to be able to handle"

I realize that! But there are OTHER versions of the 2600+. There's a 333MHz FSB T-bred & 333MHz FSB Barton...each runs at a different speed with a different multiplier. The T-bred multi is 12.5x & the Barton is 11.5x.

But if you actually have a 2600+/266MHz FSB version, the multi would be 16x.

Run CPU-Z & check what the multiplier setting is...that will tell you which version you have!

Apparently you posted right before me and yes, I am aware that there are other versions.
The CPU-Z states that the multiplier is 12.5, the AMD CPU model # is AXDA2600DKV3C and the bus speed was listed as 266MHz.

Also the clock multiplier was listed as 16.

Make up your mind. Is it 16x or 12.5x?

If it's 16x, you're OK...if it's 12.5x, you have the wrong CPU for your board.

And if it IS 16x & your CPU is running at 1659MHz, the frequency is set to approx 103.7MHz (which is unlikely).

EDIT: something just hit me. Is it possible that you keyed in the CPU speed wrong in the OP? 1659MHz doesn't make sense, but 1596MHz does! And if that's the case, you still have the frequency set at 100MHz.

You know I appreciate the help, but it doesnt have anything to do with making up my mind. The CPU-Z states that its a 12.5 multiplier as that is what you asked for and when I was talking about listed after the comma I was refering to the CPU that was listed as in being for sale, it was listed that it was a 266Mhz FSB and a 16 multiplier.

OK, if CPU-Z reports the multi is 12.5x, you do NOT have an AXDA2600DKV3C. You have an AXDA2600DKV3D. The AXDA2600DKV3D is actually a better CPU but unfortunately, you don't have a motherboard that supports it.

Before you installed the CPU, did you double check the model number printed on the core?

Yes and it is in fact a AXDA2600DKV3C.

"Yes and it is in fact a AXDA2600DKV3C"

If you're 100% sure about that, there's only one other possibility...you need to update the BIOS to be able to support multipliers over 12.5x. And if that's the case, the BIOS files are available from the 2nd link I posted in response #4

Now that I have not done, would you mind helping?

do you have a floppy drive?

Yes I do.

I suggest going with the official ECS BIOS version for now, if you wanna overclock, you can always switch over to the Cheepoman version.

Here's the latest ECS BIOS (direct download):

http://www.ecs.com.tw/ECSWebSite/Do...

Here's the flash utility (direct download):

http://www.ecs.com.tw/ECSWebSite/Do...

And here's the Flash instructions:

http://www.ecs.com.tw/extra/flashut...

For whatever reason I keep getting an I/O Error when I try to boot with a boot disk and when I was successful and booted to Dos I went to the Bios diskette and got a Error reading drive A???
Although when in WinXP I can use the A Drive without any problems???

Okay, got that to work finally, WinXP's Dos is a pita to work with.
Anyway got setup with starting the Bios Flash;

A:\>AMINF342 K7S5A0~1
<>CHIPSET TYPE - SIS SIS/SB
<>FLASH PART - PMC29F002T_V2
>ERROR 2 - FILE DOES NOT EXIST (and this error message was in red)

You 1st have to unpack k7s5a030811.exe (double click on it), then open the k7s5a030811 folder & copy the ROM file from the folder onto the floppy.

At the A:\> prompt, you should be entering

AMINF342 030811.ROM

Okay everything seemed to go well and then after it appeared to be finished it listed:

CMOS/GPNV CHECKSUM BAD
F1 TO RUN SETUP
F2 TO LOAD DEFAULT

And I chose F2 to load default like the instructions say and then it restarted into WinXP and it looked as if everything had been reset and I went into the Bios and the values appeared to be reset, but there was no difference in CPU speed as there was 100/100MHz and 133/133MHz and after booting the AMD CPU still showed up as 1200 and the CPU-Z states that the core cpu speed is still 1659MHz???

Well, if your CPU is STILL running at 12.5 x 133MHz, it can only be one of two things. You actually have a 2000+ CPU, or you have the wrong version of the 2600+. I suggest you remove the HSF & CPU, then take a closer look at the CPU model number. The last letter in the model number is for the FSB speed:

C = 266 (133MHz)
D = 333 (166MHz)
E = 400 (200MHz)

It is definitely a AXDA2600DKV3C.
Maybe there is something else in the BIOS that I need to do?

I'm done here. I gave it my best shot. Check that CPU.

What about jumpers on this board; are there jumpers that might effect limiting the cpu speed?
If so where are they located and which ones need to be jumped?

Have you actually read the MANUAL ?????

AXDA2600DKV3D
Athlon XP 2600+ 2083 MHz 333 12.5x

Yes I have and like I have said it is definitely a AXDA2600DKV3C.
Apparently there is something wrong with the cpu, I will take care of it, but I appreciate the help.

There's nothing wrong with the CPU. If it defaults to 12.5x multiplier, it's either a BIOS problem (which *should* have been fixed with the BIOS update) or the CPU is NOT an AXDA2600DKV3C.

CPU-Z doesn't lie...labels on CPUs can be changed.

I skimmed over this thread and didn't notice anything about restoring the original CPU for flashing purposes. Was that done? When booting what BIOS version number appears on the screen? You should enter the BIOS screens and look for a screen labeled CPU PnP setup page. You can manually change the settings on that page. Remember to save when exiting.
