Mobile AthlonXP on a Desktop

[Bombastik]

This may very well have been already discussed here, but what the hell.

I've bought a multiplier locked BartonXP2800+, which means´, that the only way that I can do DDR400 is at 12,5x200 which is only achievable with virtual 2.xx V on the core.

So, bummer that, I don't want to fry my brand new Barton.

I know that the Mobile Athlon XPs can be unlocked quite easly (or they aren't locked at all), but I'm quite curious about running a Mobile XP on a Desktop machine.

Is this doable? Are there any real diferences in terms of perfomance in running a Mobile XP2800+ Barton?

Because I can easly change my Barton2800+ with a mobile one, and this would mean that I could finally have the DDR400 system I've wanted...

Has anyone have/know any experiences in this matter?

Yes it is possible. Do a search on the left and you'll see many threads started about the mobile XP's. The Mobile XP2500+ is a much better deal than the Xp2800+. All the mobile bartons are unlocked and overclock very well. I have one that is fully stable at 13*200, and it will do 12*200 at 1.65v. Anyway, if you want to overclock, trade for the mobile chip.

Also, don't worry as much about running your memory as DDR400, as the ability to run a 400fsb. Your best OC results on the mobile XP's will be if you have an NF2-ultra 400 mobo capable of running a 200fsb chip like the XP3200+. But since the mobiles are unlocked, running 15*166 aint too shabby either, so even a KT400 can get some good results with one of these.

Yes, this has been discussed before...so you could probably search for. But I think it's doable. Heh...your mom's doable.

yeah I saw that. But by the length of our posts, I started typing first.

The xp-m chips are the cream of the xp die. They will run at 1.45 volts, and 45 watts. Any motherboard that gave unlocked chips on the old xp system will give you unlocked chips on the mobile.
I run mine most of the time at 11.5 X 200, bumping it to 12 X 200 for cpu intensive games. (1.65 and 1.75 volts respectively).
It worked the same on my old A7N8X rev 1.06 board, though not quite as stable (crashed a couple of times in FarCry) and in my NF7-S board.
Some people have gone only as far as 11 X 200, others have made it to 2.7. Get one.

Thank you all for your feedback.

I have an Abit AN7 which pretty much the same as the NF7-S v2.0, and I have 2x256 Mushkin PC3200 (DDR400) 2-2-2 special.

I'm what I call a "right-clocker".
I really am not interested in this point in time in going further than 2075Mhz (XP2800+).
What I DO WANT is to do it with a 200Mhz FSB (Dual-channel DDR400) instead of plain vanilla 166Mhz (DDR333).

Heck I bought my system with THAT in mind, I just wasn't counting on a multiplier locked Barton.

So my ORIGINAL idea was to buy a XP2800+ Barton (2075Mhz-12,5x166) and run it a 10,5x200 (2100Mhz).

All I want to squeeze is the FSB as the system is up to that, I don't really want to OC that far...

But I've sucessfully OCit to 12,5x200 (2500Mhz) air-cooled but with a core voltage of 2,05V, which is pretty much high...

Thank's again, I'm to change my Barton to a Mobile 2800+ or similar

I just have one more question.... The nForce2-Ultra400 DOES allow a Mobile XP right? Because I got info that the nF2 doesn't accept/work with Mobile XPs..

Sure, Mobile Xp's will work on the NF2 U400's. Here's an example. They will show up in the bios as an unknown priocessor at XXXX MHz. Not as a mobile XP.

Not sure why you want to run an Xp2800+ at a 200 bus. That isn't "right clocking" to me. But the 200MHz fsb would make for a small speed increase even at the same MHz.

The way I see it is a mobile Xp2500+ will run 11*200 at stock Athlon XP voltage or lower. So you aren't going to have more heat. You are basically buying an unlocked Xp3200+ for $100. But if you want to lower the voltage and run 10*200, by all means do it. Only the mobiles now will let you do this.

I see your point.

I call it right-overclocking because for the CPU itself it doesn't make any diffence if is running a 12,5x166 or 10,5x200....its the same speed from the processor point of view (2075Mhz)... the only thing is beeing OCed is the system around it, which is what I want because that is what I got

Actually there is a background on this FSB200 thing.

In the past I made a system using a PII/333Mhz which had a FSB of 66Mhz (the 350Mhz which was FSB100 was WAY too expensive) completly think about a bus of 100Mhz, I even bought PC100 memory at the time.

It all came down to that my PII/333 was one of first batches that came multiplier locked, so good-bye 100Mhz... that system never saw 100Mhz FSB, altought it was built for that.

Now I'm living it all again but not for the 33Mhz increase from 66Mhz to 100Mhz, but rather 166Mhz to 200Mhz (there seems to be a pattern here )

So basicly, I feel quite frustrated, so it's more of personal thing than anything else, if at least because I bought DDR400 memory and I running it at DDR333 (the perfomance in assynch DDR400 is actually lower that synch DDR333).

For instances the link you gave me, it says 217Mhz FSB.... I WANT to do that... not 166 or 180

One thing is for sure, only now I realised that not much on net is around the XP-M, and it seems that XP-M 2800 is pretty much new and rare, but not the 2500 one.

It's just that it will be hard to cover the price diference from XP2800 to XP-M2500 as the latter is more cheaper, and I have two choices:

1-Do an exchange through a hardware store which I work a lot with. This doesn't involve money.
2-Sell the XP2800, buy the XP-M2500.

For choice 1, I have the problem that the retailer will not GIVE me money as the price to what I'm exchaging to is lower, so ah heck that.

For choice 2, I have the problem by selling a second hand XP2800 and buying a new XP-M2500, I will be loosing a couple of € as the price of selling a second hand one will be the price of buy a new XP-M2500.

My only choice is the 1st one but for a new XP-M that will be around the same price of new XP2800.

Take the xp-m2500+ and some ram, or a new keyboard and mouse.
The xp-m 2500+s that I have seen were originally badged as xp3000+ chips. They were intended to run at close to 2.2 with 1.65 volts. If you are running them on desktop, you may as well use thier original rating. A nice thing about them is that you can run them at 45 watts or 85 watts, they are rated for it.

Cool I'm on to it
I'm currently validating the XP-M2500 or the XP-M2600 as the XP-M2800 is impossible to find where I live in....

Its just that if the same suprise I had with the XP2800 Barton happens on this one, I'm gone be really pissed, as I'm actually buying a SLOWER processor

There haven't been any reports on Locked XP-M have there? 'Cause I wasn't reading the forums when I bought the XP2800, and I went for an advice from a friend of mine (which more enthusiast than me); but then neither him or me were aware of multiplier locked Bartons (this was in early 2004).

I didn't recalled it, but I'm actually running my XP2800 now at 12,5x180 (2250Mhz) plain-vanilla, as at this speed it stable without any core voltage increase.

Actually, my scores are almost as good at 200*13 as they are at 217*12. This is because my hyperX needs alot more relaxed memory timing to run at 217 than 200.

If your mobo can run an XP3200+, it can run the mobile chip at a 200 system clock. If it has multiplier and voltage adjustments (which you have), it will OC a mobile 2500+ nicely. Since you have PC3200, 200*11 should be easy at around stock voltage. 12*200 should be obtainable also with a little boost of voltage. Any faster is a bit of luck to get.

I'd swap the 2800+ for the mobile and maybe get some money knocked off on a nice heatsink/fan. Although nowhere near top performance, I like the adjustable speed Aero 7 and Jet 7 from coolermaster. Crank the rpm to OC high, turn down the rpm for quiet daily use at lower speeds. Extreme air-overclockers should look toward thermalright though.

My Mushkins run both at 166 or 200 with the same timings (2-2-2-5/6), but at 200 I have to crank up the DDRvolt up a slot (2.70) but it's not significant....... haven't tested them in anything above 200 'cause just getting 200 was an achivement (remenber my multiplier is locked at 12,5)


Thanks for the advice, but I already have the cooler I wanted.

I don't like alot of noise (one of the prime reasons why I'm no a OverClocker to begin with), so I have a Thermaltake Silentboost, which is actually an excelent cooler for the low-rpm fan it has!

I'm gonna try exchange my XP2800 to a XP-M2500 or 2600.... ah heck the money, it's not that much a diference anyway.
I just hope I wont run into the same suprise I did when I bought the Barton XP2800!!

I doubt you will as the multipliers need to be unlocked on the mobile chips to allow for the power saving features in laptops. They turn down the multiplier and MHz to save power.
