Hello,

I have a barton xp2500 and a slk900 with sunon 80mm ultra high speed fan. (11x200 @ 44c)

How many volts can I put to it, before I get into serious risk territory? I'm at 1.8 atm.

Thanks!

I know, but they recommened 1.75 volts. What is the max before you would run into danger?
 
I'm at 1.85 with no problems. I've seen a lot of people at 1.85.

I'm not going any higher than this, and once all of my hardware arrives, I'm even going to try and lower it to 1.75.
 
I have a 2200+ and I am running at 1.8 and it is working fine. Temps are a little high (55-60 load), but otherwise good.
 
don't know how many of these threads there will be...

anyway... 20%... 175% .... the only thing that matters are temps. (within reason)

I have ran my 2500 at 2.1v on air since the 2500 hit the market. (I bought one the day they hit shelves) @2.6ghz. load temp = 51c

Perhaps it won't last more than a couple years like that, but frankly I don't care because I will have upgraded before then.
 
Lots of mobos don't even allow for upping the voltage past 1.85v, if that tells you anything. I've heard of guys toasting their CPUs at 1.9v but I don't know if I buy it. If you're smart about it and you have proper cooling and you're not trying to run your CPU at 65C for hours, you're probably fine with pretty much anything.

My personal ceiling is 1.9v, I just get uncomfortable putting it higher.
 
I like air 1.8 to 1.9.

Water up to 2.0v.

I run 1.95v on water 24/7. My comfortableness was listed for 24/7, you can run benches higher... so test that cpu. I actually have formed these estimates by pulling back when temps got too high OR chip just stopped giveing up MHz. I think you may find similar.... I will sometimes just give up after 2.0v now because it hasnt seemed worth it for more at times with whatever cooling. i.e that extra .1v gives me 40Mhz, so I think even, crashes down the road, here and there... so I forget it. 2.1v and up doesnt give me much more than benching MHz.

So test and find out... hell if 2.1v gave me something tangible, it should be handlable for testing in my case... no problemo... I'd probably rethink and throw caution to the wind. Seems like you can just tell when they dont like it. Hell running 2.1v without phase change and you may find your OC gone come summer. Thats no fun... I hate that. Just testing on air, 2.0v shouldnt kill her, but see what kind of MHz it amounts too.
 
so you guys are telling me that if I am running 2.1v... because im on "air" ... that its too much?? that is the dumbest thing ive ever heard.

electrical degredation + heat = risk.

If you are running 2v... and have LOAD temps of 50c or lower, there is NOTHING to worry about on an AMD XP processor. PERIOD. It will probably not last for 10 years as it was designed... but it will last for as long as an enthusiast needs it to.

I don't care if you are cooling it with apple jelly... if the load temps are below 50c ... you can run whatever kind of voltage you want through it. (within reason) Depending on core... the manufactured engineering limit is like 75c for christ sake.

That is not to say that you will be STABLE at X voltage... but you damn sure are in no danger of burning up your chip below 50c.

Anyone who tells me otherwise... how about some proof?
 
When temps are lower, super-conduction occurs so electrons will jump less at higher voltages(this is why extreme cooling gives so much). This reduces EMI thus making overclock more stable and also more safe at higher volts.

Sure you can run 2.1v on air but don't be surprised when your comp suddenly wont boot. Maximum Vcore on a Barton is +.05 so with 1.65 default that is 2.15V, so you are only 2 increments below the absolute peak volt(which may or may not be truthful). It's your money though it's not like we care. ;)

Btw it's not temperatures only that will kill your processor, but the electron migration at higher voltages(which like I said will occur on air cooling guaranteed death in no time), but if you really want to prove your extremely intelligent statement, how about turning up your vcore to 2.2V and showing us a screenshot?:D I mean u r t3h l33tz0rz u r7nz0rz 0n pr0 vc0re 0n 41r.

I agree with you on principle. If your chip is below 50 deg C, who cares how it's cooled. The voltage on the other hand is an entirely different story. I don't know what AMD specs for maximum vcore on a Barton, but I do know that too much voltage will significantly decrease the life of the core due to electromigration, regardless of temperature. It's really no big deal if you get 2 years from a 10 year processor as most enthusiasts upgrade within 6 months to 1 year :)

That being said, I've seen Tbred "B"s and Bartons die with 2.2 vcore within weeks and some have lasted upward of 1 year and still going. I think every core is different in this regard.

I'm going to check AMD right now to see if I can find the maximum vcore for Bartons. Will post back when I find it.l

EDIT: Found it, maximum vcore on Barton is 2.15.

Look at page 8.8 (Electrical Data - Absolute Ratings)
Vcore + 0.5v = 2.15

EDIT EDIT: Ok, Phollen already posted that. LOL...better have a closer look at other replies! :D
