I need to figure out a way to get more juice in my Vcore.

I've currently got my Athlon 2500 with a FSB of 220, multiplier's set at 11, Core Voltage is at 2.0, and it's still leaning towards too little juice feeding my processor. Will changing my multiplier fix that? It's pretty damn stable other than having having a leaning towards too little juice. Other than that though, Temp's fine and I'm already getting 2.43 GHz out of it. Would like to decrease my DRam voltage if possible...it's at 2.8 currently, but it's leaning a little towards too high. I'd like to keep my processor's speed where it is if possible, and gain a wee bit more stability. Pretty good for a first time overclock if you ask me.

Does it blue screen on ya? What kind of stability problems are you having? The VCore can be adjusted in the BIOS

Nothing big like that...it's just that while running a fairly light load it's constantly giving me warning beeps whenever I'm doing something because the core voltage is too low. I've got it cranked up as high as it'll go, and unfortunately I got my processor too late for it's multiplier to be unlocked. So it looks like I'm gonna have to make do with 2.2 GHz. Shoulda gotten a Athlon Mobile.

There is a way to re-unlock the athlon multiplier... it can be found on http://www.tomshardware.com. Go to the CPU section and scroll down a bit. It should be there.

 

[TeknoSiS]

No. I was wrong. It's actually a really old article. July 10, 2000. I'm still taking a look at it. It's still possible if AMD uses the same way to set voltage and FSB on the processor... Hm. Okay, here's the scoop. In the BIOS, you should be able to increase the multiplier on the 2500+ to 12.5... That is, however, as high as it goes. You may have to lower the FSB a tad if you increase the multiplier for stability reasons. I would lower the FSB first, and then mess with the multiplier. Slowly raise the FSB until you find a suitable configuration.

Will a mobile CPU even work in a desktop motherboard??

 

[Servant of Eru]

Well, from what I've been reading about it...apparently, the Athlon Mobile, since it's manufactured by AMD unlike almost all other laptop/notebook CPUs..will work in a regular mainboard. It sure would be awesome if it did...considering the heat resistance a Mobile CPU has to have to be mobile anyways...put it in a desktop instead of a regular Athlon with desktop cooling...damn, that would be one desirable CPU if it really is possible. I'll try and dig up the article I read.

Here ya go Rockn. Certainly sounds promising...2.7 GHz on just aircooling?!! Frigging amazing...though it makes sense when you think about it.

2500+ Mobile Barton Feature

 

[Rockn]

It is not the "heat resistance" it is the fact that it runs at a lower voltage, has advanced power management features that make it run cooler thna a standard Athlon. I think the above alone would make it not work in a desktop board. Perhaps some of the smaller form factor motherboards do support them.

 

[Servant of Eru]

Sounds like they have identical architecture, including connectivity...just one operates at a lower voltage and at higher temperatures...which means you can overclock the $h!t out of it.

 

[Servant of Eru]

It has a completely unlocked multiplier too because the software it runs on in a laptop is designed to make the chip fluctuate in power consumption according to the needs of the laptop...therefore it's completely unlocked....and especially overclockable.

 

[Servant of Eru]

Hard to tell the difference i'n't it?!!

 

[Servant of Eru]

Should I find out that it's compatible with my MOBO, I'm soooooo tempted to spend an extra $100 and buy it.

 

[Servant of Eru]

According to that article....with the setup I have...I should be able to get at least 2.7 GHz out of it...and that's AMD GHz, not Intel. I soooo want that processor...maybe when mine's out of date.

Hold up

You other thread said you could not overclock your cpu. It is well known that the multi is locked on the bartons, and you oc by uping the FSB, and tinkering with the vdimm as you go, you can also adjust the timmings on your memory. But you have a 600 mhz overclock, how much more do you need, you are doing very well, but to test your oc stability you must try it in prime95.

I recall telling you about the barton xp2500m when you were in the shopping stage. Also before you throttle the living daylights out of your new cpu, you should give it a week or so to burn in at stock. You must also check your temps, what are they at 2.43gh.

I did get it to a 220 FSB...only if I put it under any sort of real load (Internet, gameing apps etc.), I lost all stability.

I'm seriously tempted to buy an Athlon XP-M. And no, I never considered it when shopping because I didn't know you could plug it into a normal Socket A board.

I ended up having to leave it at the stock (or slightly over), 166 FSB, because that was the only way I wasn't getting constant low Core Voltage alert when running apps.

I don't feel like looking for your other thread, so what motherboard and what kind of RAM do you have now?

Get motherboard monitor, and find out what your voltages are within Windows....some motherboards undervolt a little, so when you put in 1.8v, it actually runs it at 1.7v....so check that out.

And may I ask, what could you possibly be doing that demands 2.7ghz rather than 2.4ghz?

And remember, there's an 'edit' button...it's there so you don't have to make 5 posts in a row...

Howdy

Here is the original thread, 2500 mobile info was there.http://forums.techguy.org/showthread.php?threadid=211887&perpage=15&pagenumber=1

It wont really matter if you buy a 2500 mobile, if your ram does not oc well. Stick with what you have got, and do not fret, you will have a decent overclock, the xp2500 should run at xp3200 all on stock volts/stock amd hsf and memory 1:1

After you run it in for a week or so at stock, increase the fsb to 200 [xp3200 speeds]. Then check how stable it is, run some games or do some encoding, if it is ok then creep up a little bit more, if you blue screen or cant get into windows, increase the vcore very slightly. Keep an eye on your temps, I run about 29c/33c, but running in the 40c 45c in ok.

That RAM should be able to go up to at least 250mhz FSB, that's what it's rated for, and many people have gotten 250 FSB's with that motherboard, but they use beta versions of the BIOS. Check the DFI page for those I guess, people seem to have pretty good luck with that board.
