KT266A and XP-Mobile

[fsumach]

Hello:

I am currently running an EPOX 8KHAL mainboard (KT266A) with a Palamino core Athlon XP 1800+ processor, 512MB PC2100 RAM.

I am interested in a performance upgrade, but I am putting off purchasing a new m/b until the new socket platforms are released. I have come up with two options:

1. Athlon 2400+ TBred (266 FSB)

or:

2. Athlon 2400+ Barton Mobile (266 FSB)

I think with the right cooling I could run the mobile at a high multiplier at 2GHz or beyond, while using a 266 FSB to utilize my current RAM. I contacted EPOX and their official response was that "mobile processors are not supported in this motherboard."

Can I do it? I was not aware the chip was any different except for the lower voltages it was capable of operating at.

Thanks in advance for any help the members of this forum can provide. I am a long time computer nerd but relatively new to overclocking!

Mike

Your KT266A board may not support Bartons at all, regardless if it's a mobile or not. There's a very good chance that it doesn't. Check Epox's site and see if it does. The best way to do that is look at the BIOS updates and see if they added Barton support.

I would advise doing a search on google w/ your board name and the processor. If they support Barton I'm almost posative they will support barton mobile... as they are the same chip just the mobile is the cream of the crop that will run at lower voltages. I just got a 2100+ XP working in an Asus A7V (kt133 non A chipset) @ 2.2ghz.... so at this point I believe you can do anything... lol!

The 2600+ seems to only have access to the low range of multipliers because it's natural multi is 12.5. I believe that if you could get a chip whose natural multi is 13 or higher, you could access all the high multipliers freely on your board. The new 2800+ mobile would be able to do this but it's not available for purchase except in notebooks (but that might change in the future).

Not gonna happen, KT333 and KT266A do not support any sort of bartons AT ALL.

Go over to AMDmb, quite a few people have gotten it to work with Kt266A boards.

Not only do some kt266a boards run Bartons, but many run the mobile Barton. Both the Abit KR7a-133 (KT266a), and the KX7-333 (KT-333) run the desktop, and the Mobile Bartons.

The trick is to use the old cut and paint method of unlocking it, Otherwise you are stuck under 13x for the multiplier. I know that it's a dying art, what with he NForce boards and all, but there are a couple of really good sites that show the Moble Barton differences.

Excellent source for cut and paint, showing the L6 bridge for the Mobile Barton

I am sorry, are you saying that you only have to use this method of unlocking for the KT-333 boards, and that with the NForce it is not necessary (to run the Mobile XP fully unlocked)??
Sorry for the confusion,

But, from what I read elsewhere the Athlon XP-M is NOT the same as the Athlon XP (desktop). The mobile has less cache and a slower true clockrate? Or, is what I read wrong?
Thanks!

Same amount of cache, same speed just diff FSB.
