I received my first of 2 mobile 2500+ chips today and the L5 bridges are intact! which mean for the uninformed that supercool SMP action should be a definite possibility without modding! :D I am awaiting the second then I am shooting for 2.5ghz from both!

CPU was bough from CPUCITY in the UK. To mod them you need to cut the 3rd lvl5 bridge to de activate the mobile info. More info available Here

Msi k7d-l. I have a 2500+ at 2.266 at the moment but they run quite hot, 50c on water or 60 on air!

Wow, I am uninformed on this "dual in disguise". How do you cut the bridge? I am only vaguely aware as to what they are. I know in the past it was possible to "connect" the bridges with graphite pencil. Is this similar? I would like to consider such a project.

Good luck,

The L5 bridges are what defines the processors ability to be either an XP, an MP or a Mobile chip. Previously you had to fill the 4th L5 pit (between the bridges) to make the XP chips be recognised as SMP capable. The mobile chips already has this bridge joined so only requires the 3rd bridge to be cut to make it SMP capable. As cutting a bridge is easier than filling a pit these chips are superb for low power SMP. Once this has done you need to manually set the multiplier, Either wire or cutting bridges. Personally I use conductive pen on the underside of the chip between pins to get the desired multiplier.

Mingon what board do you have? Would you mind trying to run them as mobiles first and let us know if they will work as mobile MPs? There is a strong possibility that CPU MSR can be made to work on the MPX platform if we can get them to do so.

Edit: noticed you mentioned it. I am also running the K7d. Someone over at overclockers.com forum has found the register for the uniproc 760 chipset and has it working with CPU MSR now.
