my friend got me 2 35watt Athlon XP-m 2500+ processors for 60bux, and to top it off with 2 dynatron BH-625LED (has 38cfm fan and tri-color leds), they both work i have tested them in my 2 nforce2 computers for 32 hours now, never shut off with 1.5volts, and they are working fine.

My question is what is the best dual processor mobo that I can put them in?
What is that pin mod that I keep reading about?

was there ever a way to get a dual 462 mobo to hit 166fsb, i think i remember reading about that a while ago.

please all help is apreciated.
 
My old MP system was based on an MSI K7d Master. I loved it to death. There are very few overclocking features as it is a server board but it was still incredible. If you want onboard LAN, make sure you get the K7d Master-L.
The pin mod is a conductive bridge between two pins that allow the BIOS to see the CPUs as MPs and, subsequently, dual-processor capable. Check out the forums at www.2cpu.com or wait for someone else to tell you how. It is a very simple process.
Good luck.

Edit: Don't forget that you will need ECC/Registered RAM for a dual processor board. It is significantly more expensive.
 
A few things:

1. I love my K7D Master as much as the next guy, but I'm not so sure it's the ideal board for running dual Athlon Mobiles - a few people have succeeded, but many others couldn't get it to work at all. Some people have reported success using a hacked BIOS which lets the chips post, and allows for changing the CPU speed from within Windows. See: http://www.ocforums.com/showthread.php?t=284909&page=1&pp=30

2. ECC / registered memory isn't needed if you're not going to use all four memory slots.

3. Gigabyte, Tyan, and Iwill (I think Asus, too) MPX motherboards have been reported to work. See: http://forums.2cpu.com/showthread.php?s=&threadid=52721 You may have to do pin-mods (wrap wire around the pins underneath, or put wire between specific holes in the socket) or modify the processors to set their speeds. See: http://www.ocinside.de/go_e.html?/html/workshop/pinmod/amd_pinmod.html

Edit: An informative post about doing the socket wire mod can be found here: http://forums.pcper.com/showthread.php?s=&threadid=310702
 
Dank: Are you effing serious about the 2 slot thing? God damn it, lol.
 
Yep. :) From the manual: "Registered DIMMs can be placed into DDR1~4 but unbuffered DIMMs can be placed into DDR1~2 only." Other people on this forum have confirmed that it works with unbuffered RAM.

MSI isn't very helpful about it though, the front cover of the manual has a little logo that says "Only Registered DDR," which clearly isn't true. Maybe they're in collusion with with memory manufacturers. :p
 
I run two 35watt 2400+ mobiles in a Gigabyte board. The voltage tops out at 1.75v and is a board limitation, I think. No clue what other boards top out at.

But I'm at a sweet 2.43GHz (18*135), and can push to 2.45GHz and 2.5GHz for a short time, but heat becomes an issue. (PSU power isn't an issue for my build, it was one of the first things I made sure to spend good money on) One day I'll also aim for some very loose memory timings and see if I can get the clock speed up, and then see what operations/task such a setup effects. (I skimped on the RAM; got cheap Kingston PC3200 to run at PC2100 speeds :p)


Anyways, pinmodding the multipliers is required. Otherwise the processors default to a multiplier of 6. 6 * 100 or 6 * 133 isn't too much fun when you could be at 18 * 133, etc...
 
the only board i know of that could reach 166 FSB was the Iwill MPX2 but they stoped making those i think 3 or 4 years ago. The k7d Master-L is a good board you have voltage control up to 1.85 volts for the cpu's and the FSB tops out at 150. But as said before in this thread you can get a hacked bios for the k7d from emboss over at www.ocforums.com and it works good for mobile cpu's. I am using it now and have two 2400+M running at 2.6ghz and did the pin mod for 18X from www.ocinside.de

hope this helps

PS: here is a screen shot of my 2400+ @ 2.6ghz http://img21.exs.cx/img21/8584/Rpkole-dual.jpg
and yes i know i spelled dual wrong on the computer name :eek:

i just found an iwill mpx2 boxed well thats what the website says, but you wouldnt happen to know what is the max cpu voltage on it would you?
 
ok just found this
Alright. So multiplier adjustment is out, FSB adjustments (100-250MHz) are still in. What about VCORE and VIO? Both are present baby! You can adjust your vcore all the way up to 1.85 volts (and it does by nature overvolt slightly, which should make overclockers happy). VIO voltage can be adjusted by switching a jumper on the board. It allows for a 5% overvoltage and a 10% overvoltage. One downside to you overclockers would be a lack of a 1:5 PCI divider. If you're fortunate enough to reach FSBs in the range of 160MHz+ with this motherboard, both your 32-bit/33MHz and 64-bit/66MHz PCI buses are going to be running substantially out of spec. When this happens your mileage may vary depending on the tolerances of the PCI devices installed in your system.
