man my 2500+ barton is hella disappointing...

[AkumaX]

just got it, cant do anything w/ it, its horrible

max i could do w/ it was 2300mhz, but couldnt find any points of stability until around 2000mhz

i know its not my mobo, i had a 2400+ @ 2420, but mang... horrible...

 

[kylebisme]

did you give it some extra voltage? mine is about the same defualt but holds nice and stable at 12.5 x 175 when i give it 1.9v.

That seems like a lot for 2187mhz when it really isnt that far from default speed and you needed to give it .3v of boost!!! Damn....I wouldn't go above 1.8v from waht I have heard from amd users and seen in some reports. I think 1.9v may be safe but it is like running p4's around the 1.7v range...

My Barton 2500+ did the 333 FSB for about 6 hours, then started rebooting, and now the system won't get past post (even booting to DOS get's a divide error) with the default FSB. So I had to change the FSB to 266 manually, and change the clock multiplier from 11x to 15x. It runs up to about 2004Mhz stable, much the same as you had, and posts as a 2600+, so I guess it was worth the upgrade. I'm going to try an Nforce2 m/b soon, to see if there is a problem with the chip, or my AN19E and/or it's KT400 chipset.

I've been running mine stable at 2210 (221x10) for 3 or 4 days at 1.750 volts... however, I've found it performs better with the FSB closer to the same frequency as my PC2700 RAM... so I've since set it at 200x11 at 1.750 volts.
It will POST at 2400 (200x12) but won't boot windows much above 2200.
I tried maxing the FSB and got it to boot at 242x9... but benchmark scores were down, I would imagine because of the RAM still running at 166.
Even at 2.2 Ghz, that's a 20% overclock, which isn't too bad. I would suspect being the first AMD processor with all that cache they still have a few things to work out... maybe as time goes by they'll get better.
(mine's a week 7 by the way)

Wow, I would expect the Barton to be much better. Has anyone ever hit 200x12 and passed the 96k in prime95?

 

[kylebisme]

new core designs are generally not the best overclockers; that is just the way it goes as if they could all really go much faster then they would just sell them at higher clocks to begin with. i got an extra 20% out of mine so i am happy.

oh and ya Duvie, it is a bit heavy on the voltage but i figure that if it does burn out sometime i can still buy another one at cheaper than it would have cost me for a 3000+ anyway and the odds are the newer one will overclock better anyway. as it stands basically running it at a speed that would have cost me over twice as much to get to get a default clocked chip and i am not really too concerned about it as it stays reasonable on the temps; ~57ºc at full load in my little mini tower.

I've said it before, but here it goes again for reference: I want to run RAM synchrous and I've only got PC2700 so I'm limited to about 180 with the FSB, but I can do 180x12.5 at 1.700 vcore rock steady, giving me 2250MHz. Ran Prime95 for 7 hours during normal use and no errors. CPU temp was 48C at the most. It's a week 8 processor. I think 2300 would be pretty easy if I just had faster memory or access to the 13x multiplier, especially considering It's only at 1.7 volts.

This is with fairly modest air cooling, an ASUS A7N8X Deluxe rev 1.04 running the vanilla 1003 BIOS.

 

[kylebisme]

wow you have a prety nice one, i can do 2250mhz but it takes me 2.1v to do it and that is too much damn voltage for me to keep it at. i did not keep it there long, the thing runs about ~80ºc full load like that. :Q

 

[ukiro]

From reading all the threads on the 2500+ here, it seems to me that people who are dissapointed run very high FSB's (200 and above) and have week 7 or earlier chips. Anyone with a week 7 who could try 12.5x och 13x (if you have access to that multiplier) with a lower FSB and see if its more stable? I don't know exactly how important memory speed is for performance though, but I guess there is a reason everyone is so FSB crazy. I'm just a newbie

 

[30wolverine30]

Mine's at 190x12.5 @2.38GHz. 1.85 vcore, 32c under load.I need a voltage mod for my A7N8X. I'll have to check the date of the chip.

 

[WalkingDead]

I'm running 198mhzx11 @1.84 vcore right now. I haven't tested with a higher multiplier yet.

my psu JUST died, i was priming for 2hrs at 2300mhz (11.5 x 200)

Whoa! :Q What brand/model, out of curiosity?
