Degradation: Would you buy a second hand wolfdale ?

[Justintime]

You sure about that, I have the CPU in its box here.

It is a MOBILE CPU, Socket A AMD Barton 2600M.

I do know what it says on the Core and on AMD's site when using the other Codes on the Core.

Thats why I stated MAX of 100C and MAX of 2.0v, Lappy are not as easy on a CPU as a desktop as they run hot.

I never nor have I seen any AMD info stating you should run it 24/7 at 2.0v and 100C.

You want to contest AMD's own Tech Info on that CPU ?.

They're just normal Barton cpus that can run fairly high clocks at low voltage, the low voltage thus gives it a higher max temp capacity as normal Bartons are 85C at 1.65v IIRC, once you cross Barton desktop stock voltages, deal with it as you'd deal with any other Barton, theres no magical special AMD mobile manufacturing lines. As you push up core voltage the max temp drops. The upper voltage limit might well be 2v, but thats somewhere you don't wanna be operating for long at under stock cooling, also even the best cooling might not negate the damage 2v might do. I'm not contesting anything, you seem to see everything as a snipe at your fragile ego. Don't bother replying as you're on my ignore list now as i'm tired of you tbh lol.

No but your clutching at straws, the fact remains pump very high volts over Default through a CPU and it will degrad.

The Above CPU I mentioned is 1.65v normall so thats why I added 2.0v as very high limit so it is compairable to a 1.2v CPu getting over 1.45v (my safe limit).

Unless you have proof dont keep making claims thats are probably BS from some noob on XS.

Is this the noob i spoke about who is at pretty much all sponsored overclocking contests and someone who has my respect because he's proven his knowledge time and time again for many years? when's the last time anyone took notice of your supposed knowledge.

I never made a claim so i don't have to prove anything - this thread is a discussion about degradation, if you can't handle the fact that other ppl have a different opinion than you maybe you'd be better off staying out of the thread. Having an opinion is fine but you always speak like it's the definitive word ...i'd say the guy above is absolutely correct, you have some kind of ego problem.

OFFTOPIC:

The fact ramains they are rated for 2.0v Max and 100C Max.

I do know a Mobile is from the same wafer but a higher yield probably from the centre so your talling me something I have known for years and have not dissproved my above info on the Mobile CPU.

Oh the little kid sets me to ignore cause he cant win this arguemnt cause he know notning about the Mobile CPU's and I got the facts printed on my Core and in the Table on AMD's site.

He was even offtopic with his BS to me when I have the Mobile CPU and stated some facts he wants to contest but cant, so sets me to ignore cause he is a baby and he is wrong.

ONTOPIC:

@ marscay, dont come the smartie and bigmouth with me, you have been asked to provide proof about your claims and have none, also others same as myself have posted ontopic (u like above kiddie) and you have nothing to come back with.

So dont ruin a thread by crying like a baby because you cant get proof to something nobody has yet.

Oh and I and others have GAVE you an OPINION, your the one now being nasty as you cant handle it, so take a leaf out your own book and stay out threads you cant handle.

XS has some clued up top peeps, it also has some scaremongers who make up crap with no proof, thats how rumours start.

 

[marscay]

The "Degredation" myth is just that, a myth. A look at my sig tells you what i am running and at what vcore. It has been at that clock since the day the E8xxx's were released. after hammering it for weeks on end, sometimes at 4.8ghz to 5ghz i have seen no "degredation" whatsoever. In fact it now needs LESS vcore at 4.6ghz than it did when i got it.

like i said before that's like saying if you're a heavy smoker you'll die of lung disease, it's common sense that some ppl are affected and some aren't.

i'm not saying it exists either just that their hasn't been this much talk of electrmigration since northwoods, to say one way or another is egotistical.

 

[rikky]

I find it pretty shocking that a few forumites are happy to basically say "I have fried my chip and if it becomes unstable I will sell it on ebay" shocking, absolutely shocking ... mind you I would do the same thing myself lol.

Well with that attitude anybody that buys a second hand E8XXX series chip really does deserve what they get, on a sidenote I really love it how all the honest sellers on ebay say "chip has never been clocked and has only ran at stock speeds but will easily clock to 3ghz (comes boxed with unused heatsink - yeah!!)".

Funny thing ignore dosen't work when not logged in. I think this post shows the level of maturity you have. Nite.

 

[helmutcheese]

Sure I believe you

Your the one who came at me with the part about " no AMD socket A + 2.0v ", no big deal but I then gave facts to show it does and can scan in my CPU and give you the Table from AMD to read the Codes.

It is Rated for 2.0V Max, it dont matter if thats at X speed or with me standing on my head running it its still fact.

You then try to talk your way out of it as you were simply wrong and again thats fine until you act like a baby getting nasty and claiming to set me to ignore all because you are wrong on a subject thats not even really the topic here.

Then the thread went quiet and no real bother until you come back with more BS.

yawn. and before you post that 'is all i can do cause i'm wrong' ... well no, its all i can come up with to deal with some ego filled kid whos trying sooooo hard to be one of the 'big boys'.

 

[helmutcheese]

Childish and still can see me while logged out and post at same time, WOW.

Get over the fact you were wrong, Im wrong nearly daily so grow up.

Cause i took you off ignore... OMG i'm a troll.. lol. anyhoo, last post from me on that subject. just one thing, how old are you? just curious.

What are the signs and symptoms of a cpu degrading - I have a e8400 running at 4GHz with 1.3875v (1.360v after vdrop) going through it?

I just want to be aware of what I should be looking out for

SW.

Loss of overclock at previously stable voltage, more voltage needed and eventually even that may fail, gradual decline in OC with more voltage needed at previously stable settings and possibly eventual loss of even stock speeds and chip just not being able to run any speed stably if its anything like SNDS.

 

[helmutcheese]

@ sam.wheale, Absolutely none to show the E8X00 Degrades anymore than any other CPU, yet.

 

[pieman109]

This probably a bit of a generalisation (is that a real word), but is there any indication of how long this degradation takes to manifest itself or is it dependant on voltage applied (higher voltage, shorter life span)?

With mine it was exactly as Justintime said a couple of posts above. An overclock that was previously stable for 16 hours at Prime small ffts would'nt even boot let alone run with a higher voltage. I went from a stable clock of 4Ghz at stock voltages through 4.2 (1.375v, 16 hours prime), 4.4ghz (1.5v, at least 12 hours prime) all prime stable and tried for 4.5Ghz which i could'nt get stable (most i gave it was 1.52v). I then went back to my previous clocks and could'nt get them stable at the same previous settings. 4Ghz eventually got stable at 1.345v vcore at which point i got fed up with the damn thing. This was a E8500 in the rig in my siggy and all it took was a week. I believe it is to do with the voltage applied so when i get another one it will not be getting more than the VID on the box.

 

[V3g3tto]

Voltage around 10% above VID should be fine fine. Which in my case would be 1.46. Got mine running at 1.475v. I've seen people go up to 1.6 on my chip. If it fails i'll throw it in the bin, i have no problem doing that, because with a VID of 1.325 i'm not too impressed to start with.

 

[Devious]

Just noticed this, possibly another report of degredation?

Also my E8400 is getting more and more unstable, needing a tiny increase in vcore to keep stable at a frequency which was fine a few days ago. it seems to be degrading in front of my eyes.

I’ve had no core 2 that has exhibited this characteristic, and to be frank its scaring me a little.

Feels like the chip is slowly dying

Will be going back to my trusty Quad asap.

[helmutcheese]

BTW if peeps put stupidily high VCore and esp the PLL voltage being set too high it will kill the CPU faster than VCore, and again this is for any CPU.

It is really frustrating. I don't care what other people are saying. This is really happening and there are reports all over the internet about the Wolfdales degrading and even just simply dying (one case was a E8400 dying after just 1.5v). Having experienced it myself i have no doubt in my mind that there is a problem with these cores when overclocking them heavily. The same thing has not happened to any of the other C2D cores and from my own previous cpu's (E4300 &Q6600) i have never had a single problem with them. My E4300 was clocked to 3.4Ghz with 1.425v and the Quad to 3.8Ghz with 1.575v and neither of those ever had any sort of problem. In fact i still have the E4300 in my second pc. If the new batch of Wolfdales are no better when they are released then it could find itself back in my main rig.

 

[helmutcheese]

After just 1.5v ?, its a 1.2v CPU with a even lower VID.

It aint a E6850 where you can simply pump 1.55v safely on good cooling through it.

If you read all forums you would know that 1.4v-1.45v for now is the limit most class as safe.

This is a 45nm CPU thats new out, so you cant compair to other CPU's and at the end of the day its rated for X volt and X speed, there is no guarantee of overclocking.
