the old Athlon XP-M mods

I'm putting together again some old hardware to get them crunching again. I was crunching with the hardware years ago.

Three of the rigs are XP mobiles on Abit NF7 v2 mobo's. With two of them the CPU's are still in the mobo's and mods done. The third is a XP-M 2500+ that I never got around to getting running back when I was doing that stuff years ago.

So I'll have to do the mobile mods again for that CPU. I can't remember precisely what the mods were for.

What was the reason for doing the wire mod where you short two of the socket holes? And why was it necessary to change the BIOS to that altered BIOS (can't remember the name of it)?

I've got the Badass mod'ing guide saved somewhere but don't remember where now. Could take a while to find it again.

Thanks
 
Ha the Abit NF7-S 2.0 and Athlon XP-M's the good old days.

Was the mod to allow multiplier unlock upwards as well as down?

Though if the processor year/week is before 0340 I think then it should be unlocked anyway.

AMD started locking the Athlons after year/week 0340 because the mobile bartons were being overclocked and sold as higher specced chips.
 
Interesting, I didn't know about the 0340 thing. I've got it with me here: first off I know it's from one of the good production runs. If I remember right, the code IQYHA indicated that. There's a four digit number after that: 0414. So I guess this one needs the mods then.

Anyway, though I never got around to installing and trying out this one (back when I was OC'ing these) I had an identical one (same production run code) that I did install and OC and it responded well to the mods and OC'ing. Don't remember the exact resulting speed.

Cheers
 
I had one of those mobile barton 2500+'s that did 2.8Ghz I remember. Great chips.

Yeah 0414 would be after they started locking the multiplier upwards.

Even with the multiplier lock though they are great clockers.
 
Yeah the xp-m 2500 that I did install OC'd well and I didn't really push it in terms of volts as I recall. Also I think I did try raising the multi and if I remember right, I put it back to normal

Ok, but if I understood you right, one or both of those mods unlocks again the upwards multi right? I recall that raising it on the other chip gave an unfavorable result of some kind (I had the mods done with it). Maybe I raised it at too high an FSB or something.
 
I didn't need any mods to get my XP-M up to 2.6GHz, I was lucky enough to have one unlocked out of the box.

The 35W chips were the ones to keep an eye out for.
 
I thought all xp-m chips were unlocked, and L2 mod made the fsb 200 by default supposedly to help with higher fsb clocks.
Seem to remember Mantaray XT bios is what i used in my nf7.
 
nkata: Wow that interactive page goes way beyond what Baddass's guide had (thanks Baddass for your XP-M guide). That's interesting. Didn't know there were so many wire mod variations. Thanks for the link.

troops: That reminds me, yeah one of the wire mods was for raising the max possible FSB.

With all your inputs I'm starting to remember these details again.

Cheers
 
I used to oc tbred 1700+ CPU's and got some great results on air with incredibly noisy delta fans on thermalright copper heatsinks. Be interested to see your results posted. I used abit motherboards as well both via and nforce.

Ha yeah I had years ago a Thermalright copper heatsink on a P4 with the really strong and loud orange 80mm fan... ahhh that was ridiculous loud :p

I did OC one of the two 2500 xp-m's back then and I'll get that one set up again too. Don't remember the speed. This second 2500 I didn't get around to installing back then but I will install it now. I probably won't push it super hard, but I want a good (but 24/7 Prime stable) speed for 24/7 crunching.

I'll have 4 rigs crunching full time and a 5th crunching part time and maybe a 6th added to them a little later.

Cheers
