wierd 2600+ problem

[dafadau]

What's the default clock speed for a 2600+?? Mine runs at 2088Mhz, and I'm sure the listed speed is 2130Mhz? What are the default FSB and multiplier?
all benchmarks say mines too slow!
thanks!

There are two XP2600 thoroughbred processors, one that runs at 133 FSB, one that runs at 166 FSB

133 X 16 = 2133 MHz
166 X 12.5 = 2066 MHz

I too have an AMD 2600+, which also runs at 2088 with a FSB speed of 166. The box it came in is marked "Palomino". Your CPU must be identical.

This screen shot may be of help...

this is what I get

You have a newer Athlon core with 333 FSB. They are rated slightly lower than the Thoroughbred core with 266 FSB but actually will clock a little higher. There were many sold as 333's that were 266's. I had one and it took me forever to figure out that was the problem. AMD admits to having mislabeled a whole 'batch' of them

2088 is a 333 chip... I have 1 and the default multi is 12.5 .... but not on mine.........

ANYMORE........

Ok, you baited the hook, i swallowed it, I'm hopping the net now.....What did you do?

Cut the 3rd L12 bridge??

I did that, sweet, huh?

[muzz]

I cut the last L3 (On a 2600+/333 chip..... the other end is already cut.. so there should be no confusion... ) To get multi's over the default of 12.5, now it defaults when cleared to a 2400+ BUT at 20x100fsb.....2000mhz, now I get all the multi's I have tried.. I don't care what it defaults to.

The L12 is for FSB( for folks that don't know-changing a 166 chip into a 133 chip) clocking, as the 166 chips seems to be more difficult to get up to higher clocks.

You already cut yours?
On the 8RDA?
Results?
Did you try the JCLK first?

[Uncle Bob]

Ok, no I'll hop off the stringer and swim off now! LOL. I use it on my Chaintech board and it automatically gives me all the multipliers, just don't ask me how....I can't explain it. It's beautiful, tho!

[muzz]

Ahhhhhhhhhh OK then.
Seems like the problem is a little different with the CT then, maybe it don't like 166 chips....
Glad it's working for ya there UB..:beer:

[Uncle Bob]

Spank that chip!:-D

Yesterday I reset my bios to optimal, exited all other running programmes and reran 3dmark, and I only got 5725!!!

Have you tried using Powerstrip to tune your card? I went from 9000's to this using it. Also what drivers are you using? Is AGP Fast Write disabled? (it should be).
