Ask and ye shall receive... 😉

As for voltage, I'm planning on keeping @ 1.75v or lower. This is just a backup system, and I prefer the quiet over a few more mhz. I generally like to find the upper end of the chip, and run just a step or two below the max o/c.

I think that will be a tall order. 2.5 GHz and 2.7 GHz are not exactly close. I am getting my 2500+ M as I wrote this. I am hoping for 2.5 GHz on one of my power boards, everything is ready, even Exos watercooling if it works well.

The benchmarks are fine but Barton at 2.7-2.75 GHz has about the same benchies as AThlon64 at 2.4 GHz. The key is bang for the buck of course. I jumped on every bandwaggon that was there, sometimes with a disappointments, hopefully not this time. 😎

Yeah, I agree. 2.6Ghz might be possible with 1.8v+, but I'm really not interested in the extra 100mhz just for bragging rights...I grew out of that long ago. 😉 I'm sure if I wanted to get a huge case, with tons of high speed fans, and a $50+ HSF with a 50+dBA fan, and run a 2.0v+ vcore, I bet 2.7Ghz would be doable..but again...pass.

It's running 56C under full Prime load (max heat), with a 34C ambient case temp. The temps @ 1.45 never went above 40C, and hovered around 38C under full Prime load @ 2.2Ghz.

:beer:

Edit:

I'm running this 25dBA Coolermaster fan on the Alpha 8045, and it's setup in a AMS silver gMono case. I am running two 80mm Panaflo L1A's in the rear, and no intake fan.

Temps seem pretty good, but then again, I expected them to be for such a low voltage. Those chips are sweet.

You might want to give your info to these guys.
 
I don't think it would be hard to get 2.7 from that chip (your chip). Hardly anyone is 2.5 at such low volts...very impressive...just look at OC thread...but as you said who cares about bragging rights.

I am seriously considering this.. My concern is although I'm watercooled CPU, GPU, NB and silent, I'm worried about the capacitors and mosfets getting so hot and I'll have to crank up air flow though the case.🙁 Many report this to be a problem. Also I'm not sure a 400 watt antec PS which I've modded to be fanless can handle it.

I'm running a older, single fan 400W Antec...with the fan replaced with a 21cfm L1A.

Voltages are very steady...the only one that drops a bit as speed increases is +12v, and it only drops down drom 11.98v idle to 11.85 under Prime max heat..

Edit...funny thing is this is my first Barton..heh. I've been holding off because I was already running a 1700+ Tbred-B 1.5v @ 2.3Ghz, 1.80v...

What is the model number of your PSU?
 
yeap, that's the steping to get for great overclocks on the mobile bartons! I've had a quite a few "IQY" steppings on 2400+'s to 2600+'s and they all are great. That's the stepping of my 2400+ in my sig too.

Gotcha. I have the PP412x. I can adjust my rails..not sure if you can, but you may be able to.

You know what...now that I think about it, I think it is the PP412X I have. The AMS case makes you mount the PSU "upside down", so the label is hidden and I can't see it through the window. I'm going to be doing a fresh install later on tonight, now that I have found my "sweet spot". I'll need to get in there to hook up a floppy for the SATA drivers, so I'll confirm then.

No, but take comfort in the fact that I am overclocking in the name of G_d. 😛😉

Oh boy Oh boy!!!
I get 2.511 GHz on 1.75V with mine. Easy! This might not be the limit. I might even decrease the voltage. Temperature is about 40C (my room is kind of cold, 17C only).
That is way better than my best Barton so far, I had 218x11 with 1.85V. This is 218x11.5 with 1.775 (for Prime95). Temperatures are quite low on my NF7-S, 44C on Prime95 load. This is one rocket though mine is only a week 48 of 2003.

Damn you and Insane3d! I want this chip! 🙁

Nice, mines' a week 50 and they seem to get better every week!
 
Actually I am testing it now at 2.58 GHz using 1.825V. Looks OK.
Prime95 errors out after few minutes. I think I should apply more voltage but it is too good to enjoy to kill it so soon. Maybe later. 2.5-2.55 GHz not too shabby.

I'm pretty sure you could sell your XP2800 for at least $100 and then buy a mobile XP2500 yourself.
 
How do you tell the difference between the mobile Athlon XP Processor and a Athlon XP Processor? Are they the same, will the KT400 Soyo Dragon Lite support Mobile XP Processors
 
This is pretty much what I got now confirmed.
My 2500+ mobile runs 213x12=2556 MHz at 1.85V, prime95 stable for two hours, no need to do more. Under this kind of load I get 47-48C temperature which is acceptable. When I try 214x14 Prime95 errors out after less than 10 minutes, actually freezes so I have to do a hard reboot.
I believe this is the limitation of my processor since my memory, BH-5 can go over 220 at 2-2-2-11 without problem otherwise. In either case this is an excellent overclocker and I can only envy the people that are getting 2.7 GHz, mine isn't capable of that.
As far as benchmarks are concerned this is not up to Athlon64 at 2.4 GHz, that is still better though it is sort of close and given the budget differences I vote this mobile thingy the best bang for a buck.
