Hi!

I would like to upgrade my CPU from a 1 GHz tbird to a Barton XP2500+.
Officially this is not supported by my motherboard, since it does not support a 166 MHz fsb. However, it does support all the t-bred 133 MHz (fsb) up to 2600+. Is there a way to cut and/or paint the bridges on the Barton, so that it will be recognized by BIOS as a t-bred with a 133 MHz fsb?

Any advice or experiences?

Thanks in advance for any helpful pointers!

- Harald H.

It works with FSB 133MHz and multiplyer 14 @1866MHz. I have one on my a7v333 rev 1.01 that also supports only FSB 133MHz (official) (it means the bios don't support this processor but it runs very fine) sorry for my bad english AMD Athlon X2 3600+ @2800MHz - 1.35V / 280MHz Referenztakt / 4GB DDR2 800 RAM / AMD690G

There is a way to change the Busspeed. The bridges where the Speed is encoded are the l12!

On an 133 MHz. Tbred the l12 look like this: l::: (l = closed, : = open)
an on the Bartons (166 FSB) the l12 looks like that: l:l:

Gotit? :wink:

(I've cutted this 3rd l12 on two of my Bartons, and they both work fine on my MSI K7D (after connecting the l5 - the MP mod and changing the multiplier to 15 - but thats a different story)

You are aware that u will have to change the Multiplier as well? (or u r going to end up with an XP1700+ (11x133) with 512 KB l2 Cache!)

15 should be a save (in the meaning of conservative) bet. Both my XP2500+ run at that multiplier with only 1,5V VCore (stepping AQXCA 03(11) - not completely certain 'bout the week)

Putting myself in your place, I would consider to upgrade the Board and the Rams as well! (there is a hell lot of Performance between the KT133 with SD-Rams and any other Chipset that supports 166 MHz. FSB with DDR Rams)

Hi!

And thanks for the replies.

I'm curious how they are recognized by BIOS? Is SSE enabled?

For me, the best upgrade to my computer is a Barton (which currently here in Norway sells for approx. ?100). I'll pop in the fastest processor I can get (and the larger cache of Barton helps offset my slow memory system somewhat) and live with it until Athlon64 platforms become available and cheap.

A mobile Barton is an interesting alternative, but perhaps more expensive than the desktop version?

So long,

Harald H.

If the Bios is supporting the Tbred CPU up to XP2600+, the system should also works fine with CPU's based on barton core. The mobile CPU's are hard to get at "normal" PC-shop's. I did get my one from a person who works at AMD. The price will be 20% over the desktopversion of the CPU.

The easiest and cheapest way to use the barton on your system will be a desktop barton modified with the Pin-Mod . unfortunately in german language.

An XP2400+ will perform better at FSB133 than the mobile Barton (2000MHz vs 1866MHz), the cache has no effekt on your system. So this would be the best solution for you (and a cheaper one).

i think u should also change your board and memory because the barton will never run with full power

first its slown down by the FSB of only 133.. second your SDRam is a huge loss of performance..

and a new NForce for example isnt very expensive ( or maybe a K7S5A - think its better than your kt133a ) and DDR - Ram is also cheaper than SDRam ( here in germany )

so sell your CPU and Board and RAM and buy for example

- low cost -
k7s5a
pc266 ram
barton

or better
nforce or kt333 board
pc333 ram
barton

when you dont want to change your board a normal XP will be better because the loss of performance isnt that big and you will save some money

-- and i think you can wait for a long time until the amd 64 is cheap

@NWD

er hat aber gesagt, dass er auf den Athlon64 wartet (einschl. Plattform) darum wird es sich kein neues mobo kaufen wollen, obwohl es natürlich nahelieged wäre um nicht die neu erworbene performance von SDRAM ausbremsen zu lassen...

"Und?"
"Der AMD Athlon war wirklich schneller!"

Folks,

Thanks for the input. I am a cheapskate. I just want to get my current platform running the best it can for a sub 100,- Euro cost. Some of my applications, such as scientific computing and video-encoding are mostly CPU limited, and my system would get a significant boost going from a 1.4 GHz t-bird to a 2.x GHz overclocked Barton or t-bred.

Urbs, the pin-mod looks interesting. Maybe I'll revive my rusty high-school German and dig into it....

Kammerjaeger, I would offcourse overclock the CPU. The larger cache of the Barton should have some effect, and I would expect the Barton overall to perform better than the t-bred at the same fsb and core frequency. But the difference may be small and not worth the hassle to modify the Barton....

Cheers,

Harald H.
