Thinking about OCing my 2500+ barton

ok.. so i hear it's a waste to buy the 3200+ cause you can OC the 2500+ to a 3200+.. here are my questions.. one.. i'm honestly scared to try unlocking.. i don't want to waste money, so i don't want to screw up and damage the CPU. So, my question is.. Is it posible to make it to 3200+ speeds? is it imposible? or is it a gotta try it to find out?

Like i said, if i were to try this it would be with a locked CPU. so all i can do is up the FSB.

My Ram is geil DDR 400 (1 gig)
My HSF is Thermal take silent boost
Mobo is the Asus A7NX-E deluxe.

Last question. I know changing the FSB will change the PCI and AGP bus.. should i worry about this?

Here's another thing.. my CPU at stock is 166x11, while the 3200+ is 200x11.. so all i would have to do is up the FSB right? and maybe Vcore?
 
In my experience, it's been simple getting a 2500+ to 3200+ specs just by raising the FSB to 200. But, it's not a sure-shot thing. You may or may not achieve 3200+ specs.

As for the AGP and PCI frequencies, nForce2 motherboards have AGP/PCI locks, so don't worry about that.

And yes, just up the FSB to 200. I usually have to raise the vcore by .5 to achieve Prime95 stability, though.
 
It would be cool if more peope can give me their experiences overclocking this CPU without unlocking.. :)
 
I have the same mobo and proc. All I did was set the FSB to 200 and ran prime 95. It was stable for 24 hours so I knew it was stable. If it is not, try raising the vcore a little bit. Just watch the temp of your proc when u do that. More voltage means more heat, but I think your heatsink can handle it. Good Luck!
 
when you say stable for 24 hours.. you mean it crashed after 24 hours.. or you only tested to 24 hours and shut off prime 95?


Thanks for the input guys.. i'm definatly gonna OC and torture test this bad boy tomorrow (it's sleepy time right now :) )

I have the 2500+ running at 3200+ for over 2 weeks now without a problem. I didn't test it on prime but it runs all my games just fine and doesn't lock up. Btw I usually get 40-42C idle and 48-52C load with the stock HSF.
 
I have the Barton 2500+ overclocked to 2.5GHz on air. With aVcore of 1.75, I never run Prime95 (make that, never have), but I'd say I am fairly stable as I can game for hours on end or just plain leave my pc idle for weeks on end and I've never recieved any errors. However, I am certain that if I run my processor on Prime95, it'll die within 20 minutes, maybe not. I'll never know. ;)
 
ive had a epox 8rda+/unlocked 2500+ only got it to 2.4 ghz stable (and at the time, i knew shit about overclocking)

now i have a shuttle sn45g/locked 2500+ that hits 2.5ghz (not stable enough for daily use, but stable enough for gaming on hours, cause it runs at about 54c load)
daily use - i set it to 200fsb, and lower my voltages down to 1.475 to keep it running cool (yup its 24hr prime stable also;))

every barton i attempted to OC (around 6), has hit 3200+ with no trouble

yes set it to 200fsb, but don't touch the vcore unless its not prime stable,
 
I am running a A7N8X Deluxe Rev 1.04 with a Barton 2500 @ 200x11 and the thing is rock solid. I did not have to unlock any multipliers, and was stable on Prime 95 for 24 hours. My PC runs 24/7 and I game all the time with no problems. I absolutely love this CPU!!!!! I am using a solid copper HS and a 80mm fan.
 
I ran my 2500 at 3200 speeds since last September when I got it. Stock runs 33C idle, according to the onboard sensors. Full load is ~37C from same sensors. Asus A7N8X-X.

Running 3200 speeds at the minimum voltage on the Asus board (1.68V) raised my temps to ~37C idle, ~43C load. 100% stable. These temps were with my Rev1 Aeroflow running 7V.

I was running it at 225x10 for the last week or so, with 45C idle and 63C load, using my poor little 512MB stick of PC2700 Kingston ValueRAM. :eek: 1.872V

Back to stock 2500 and 1.68V right now. I like the temps better, until I get the rest of my H2O rig.

I convinced friends to go with the 2500 (some locked, most unlocked), and they're all running 3200 now, rock solid.

Same here, and mine's working with the same success.
 
Ok.. so i set the FSB to 200, and well it failed after 4 minutes of prime95 (max heat test).. i'm very sad.. what's the deal.. was there something i should have done? Or am i plague with a chip that can't OC
 
u sound exactly like me look in the thread prime95 failed overclocking and u'll see my results.
