I wanted to set my system back at the nice cool stock speeds, so I removed the pinmods from the cpu sockets (were at 18x). But now both CPU's show up as mp2600's instead of mp2800's (running at 15x for some reason now).

I know I could probably just pinmod back up to the stock multiplier of 16, but I really wanted everything to run mod-less (not to mention that those 80mm fans are annoying to remove & re-attach to my slk-700's).

I just cant think of what would make them do that, I'm certain there are no pins left in the sockets.

On my k7d, i have two 2200+'s, but they are overclocked to 2400+, but the bios reports them as 2600+, it's weird, i know, but i am sure it is just a labeling problem, the bios seems to judge what chip you have by the speed of the fsb sometimes, and others the final MHZ of the cpu.

anyway, is your fsb set to 100?
if so put it to 133.

Is the speed/Mhz/Ghz of your cpu correct?
if so i would ignore the bios reporting of the cpu type, check the Mhz and fsb in windows using cpuid or cpu-z, if they are running at what they should be, then it is not a SERIOUS problem, because your chips are runnig at the proper speed, if not, then make sure that the BIOS settion for your chips are set to AUTO, and not anything else.

did you do any bridge mods?

"Is the speed/Mhz/Ghz of your cpu correct?"

Nope, they show up at 2000mhz(133x15).


"for your chips are set to AUTO, and not anything else."

Yup, everything is correct there.


"did you do any bridge mods?"


Nope, just wire pin-mod's via the socket. Though before I posted here earlier I had removed a single wire I missed in the 2nd CPU socket. Though the CPUs were running at 2600 speeds before I removed that as well.

They were running fine at their default/stock mp2800 speed (~2130mhz,133@16) before I started overclocking them.

What BIOS are you running?

[walaka7]

have you tried clearing cmos? sometimes i need to do this and a couple of boards when i code the multi correctly

[MRD]

Athlon MP2600+ and MP2800+ chips are the same multiplier and FSB. The only difference is that the 2800+ is a Barton and the 2600+ is a thoroughbred (512MB cache vs 256MB cache).

Your BIOS obviously can't recognize the Barton as a Barton, it just sees the multi and FSB and looks it up in a table and sees that that multi and FSB mean that it's an MP2600+.

take the BIOS 1.91 - that solve the problem

[doolee]

"have you tried clearing cmos?"

Yup, no difference.

The BIOS is the latest, also both cpu's worked properly even before I flashed it a couple weeks ago.

I just used the wire-pinmod method again to force the multiplier back to 16. Now one of the cpu's is at proper 2800 speeds, but the BIOS says the cpu's are mismatched and will only boot in uniprocessor mode.

I guess I gotta take the bitch back apart and double-check that the wires are still in the correct places.

I still wish I knew why in the first place it runs my cpu's at 15x instead of 16x. I dont know how I would have physically damaged them since all I've done is the wire pinmods.

"table and sees that that multi and FSB mean that it's an MP2600+."

If the 2600 & 2800 have the same FSB & multi then wouldnt the BIOS see my cpu's as 2400's then? Since my system is setting both of them to 15@133 instead of 16, running at 2000mhz instead of 2130.

Maybe you still have a wire or two stuck in one of the sockets. That could certainly cause this problem.

that's not necessarily true...

there are two MP2600+ versions...one has 256k cache (that runs at 2.133ghz with a 16x multiplier) and one has 512k cache (that runs at 2ghz with a 15x multiplier)...

the MP2800+ has 512k cache and runs at 2.133ghz with a 16x multiplier

"Maybe you still have a wire or two stuck in one of the sockets. That could certainly cause this problem."

If theres wire in a socket its definitely not a whole piece of wire, I inspected both sockets thoroughly. There were definitely not at wires connecting any holes in the sockets.

Not until I tried to pinmod them to 16x and hopefully force them to run at the proper speed. The 1st cpu worked at 2800 when it was alone, but when I got the 2nd one pinmod'd properly both showed up as mp2600's.

So after all that crap I'm back at the beginning.

I've even switched cpu's just to eliminate that possibility. It had no effect at all, both run fine pinmod'd to mp2800's when used alone.

Not a huge problem I guess, just annoying to not know why its happening....
