Yup... I don't know of a Barton that will do 2.3 on 1.65 volts... mine won't even do 2.3 on 1.750 volts... it takes 1.8 to get it to run Prime 95 for longer than an hour at 2.3. But it runs 2.2 on 1.65 volts for at least 12 hours.

I've been running mine like this for months

Nice CPUz shot. Mine looks identical, except it identifies my chip as the 3200+, and the Voltage is 1.584v
 
That's an older CPU-Z shot from months back when I first set this system up, I'll download the latest and see if I get the same results 🙂
 
Still doesn't ID mine as a 3200+ like your's despite the nearly identical settings 😕 pic EDIT: I think I know why it dose not ID it correctly, I still use the original E1L bios for my 75MRN-L and it doesn't officially support 400FSB.

No, you won't get 2.7-2.8 with water. You guys don't understand... this isn't an issue with heat... it's an issue with the design of the CPU. Because of the Athlon XP's relatively short pipeline it physically can't run that high without super cooling it like with liquid nitrogen or prometia... the reason those work is not because they get rid of the heat generated, it's because they cool the CPU down so that electrical resistance is a lot lower, and the transistors can switch faster. Kryotech called it thermal acceleration when they were in the biz.

You are wrong. Actually it is an issue with heat if you are running 2.0V or higher, even 1.9V. True, the design of the CPU limits the overall speed you could ever obtain, but as long as you can keep feeding it voltage w/o killing it, and keeeping it cool, then you will find the true limit of the chip. I know that if I tried to run 1.9V on my 1700+ itd get pretty damn hot, however with chilled water or a peltier/water setup I could do it just fine.

You misunderstood what I'm saying... of course if you use a retail heatsink heat will be an issue. If you can get rid of the heat generated at 2.8 Ghz at whatever voltage it requires, it's not an issue, and the physical properties of the CPU become the issue. And unless you "thermally accelerate" the CPU, you're not gonna hit 2.8 Ghz... even if you're running at room temp.

Well I didn't misunderstand what you said, its just the way you worded it. You said the issue isn't with heat, and it isn't as long as you have the best cooling. Eitherway, the consensus is you need extreme cooling such as prometia, etc for anything (mostly) over 2.7 unless you have a really hardcore peltier setup. I wish Prometias were cheaper.

No... extreme cooling is not needed to deal with the increased heat generated by the CPU... extreme cooling is needed to alter the physical properties of the CPU to allow those higher speeds.

8th one down..

That's not 3GHz... And LN2 coolers are not intended for long term day to day operation either. They are meant for screenshots and a run of 3DMark. Let's see someone get an Athlon up to 2.7GHz and Prime95 it for 24hours at that speed before we get all excited here.

I seriously doubt it's stable at that speed on just water. A Peltier is not water cooling. A Peltier cools the the CPU down well below 0 C if I'm not mistaken... which falls into the category of "thermal acceleration" more appropriately than just a really good cooling solution.

*EDIT* Hell, my XP2500 will POST at 2.5 Ghz, and BIOS temps don't go above 60C when I'm just sitting in the BIOS... but the chip physically isn't capable of operating at that speed unless you freeze the damn thing.

i'm not sure, but visit xtremesystems.com
the overclockers there are really hardcore

Sorry but your wrong with LN2 people are getting 3.6Ghz with an AhlonXP

3.6Ghz Athlon XP

Don't apologize... I'm shocked as hell! :Q I wonder how long those machines run at those speeds before the CPU gives up the ghost?

 
Okay,
so which is the cheapest AthlonXP/or barton cpu that will overclock to 2.5ghz on Air Cooling at the lowest possible vcore voltage and tempterature? 😀

Oh is it not? Try running an Athlon at over 2.1V on air...just try it.
 
Maybe my shuttle SN45G Enhance power supply is too weak because I just overclocked the cpu to 2.2ghz at 1.775v, but it will only do this speed on a 133mhz fsb frequency. Once I raise the FSB speed and use a lower multiplier, it won't go to 2200mhz. Can it be something else besides my power supply? 2266mhz seems to be the highest this cpu will go.

Damn, is your brain that simple that you can't understand what I'm saying? You can't run at that speed without altering the physical properties of the CPU... even if you had a heatsink/fan or whatever you feel like using that kept it at 40 degrees C, it would not run at that speed. You need to cool it to sub zero temps to get the transistors to switch that fast.
 
My Barton has been operating stably at 2600 mhz for over a month now (on watercooling). It boots at 2800 mhz and loads windows but it isn't stable.

Regards.
 
Now, it's at 2.05ghz@1.775v, at 217mhz FSB, and ram at cas 2.0. I'm really suspecting that my power supply is holding me back and maybe lacking the ability of a 2.9 voltage for my memory. Ideally, I want my shuttle to run at 2.266ghz, 225mhz+ FSB, and cas 2 memory. Anyone know of others passing the 223mhz FSB speeds on the Shuttle SN45G systems?

Sweet. Can you do some benches and show us the results? More of us might venture into watercooling if the benefits (real) were more apparent to us. 🙂

 
DAPUNISHER,
I've heard that too. Does anyone remember how to calculate the power consumtion of your pc components so I can compare them to my power supply specs? I forgot how to do this! 😱

omg. THANK YOU, you are "da bomb" punisher. :music:

So, what is THE AthlonXP 2500+ Barton stepping to look for that will easily overclock to 2.4Ghz at 200mhz FSB speed in my Shuttle SN45G computer?:sun:
