45Nm WARNING - Page 2

post #11 of 30
I'll be the 1st to agree that the 45nm certainly have their share of quirks, eccentricities, temp reporting issues, and errata.
(With a large dose of wierdness thrown in.)

But they do overclock like a banshee and that's why folks are lovin' em at 2 bills.
I have heard of very few "failing" (dead, defunkt, deceased, passing, morte).
Intel has sold millions of the 45nm (flawed or not).
If you overclock you can always kill something with excessive voltage.
(The kewl danger part)

Lot of posts on forums regarding "degradation".
Chips needing more voltage to run stable as time passes.
I'm more than willing to believe that chips (along with all the other components) degrade with use.
Component values change with heat. Just the way it works.
So I'm not too sure it couldn't be something else (not the chip) that causes an increase of voltage to be needed for stability.
Certainly most Northbridges need a little more voltage as FSB goes up.

(And hopefully someone will come up with a standard app to determine what is "stable" soon.
It's crazy with so many defining "stability" in a different way.
Be kewl if the stability app could test CPU, Mem, GPU and Storage in a nice Batch.
Heard too many times guys say that their rig is stable at 9 kagillion MHz except it won't run 3D03, they lose their network or audio, and HDD transfers become real slow.)

1.36v or so is a nice number to keep the voltage under if you want to play it safe.
Of course, if there are voltage spikes on the AC line, PSU 12v, or even in the PWM circuit all bets are off and please ignore the previous sentence.

Like anything else in life, if you can't afford to lose it, take real good care of it.

I've taken mine past 1.6vcore a few times and around 1.53vcore for a good number of benches. No degradation thus far.

Allright I guess this is the golden rule:
No one knows if in the near future we will be able to OC, Intel might get rid of the FSB concept in the newer generations, which means that overclocking could disappear or become extremly harder (such as overclocking by preventing contact between specific CPU dots and the motherboard's pins). But what WILL REMAIN TRUE IS, as we are shrinking our architectures, CPUs become a lot more sensivite to temperature, and the circuits will deteriorate a lot faster when running above normal voltage. Starting at 45nm, we are really starting to realize how voltage deteriorates the CPU, and as we are moving towards 32nm, it's something to remember.

You can overvolt any 65nm as well. The difference is with the e8500 you can get a higher overclock at a lower voltage, lower temps, and it will beat any 65nm dual-core clock-for-clock. You can just get an e8500, and just never go above 1.36v.

Well did the people who's E8400 failed push them past 1.3625 V? Because I don't plan on taking it past that, if I can only get 3.4GHz at 1.36, then that is how it is going to stay, I'm not ruining my chip

Bah! Pump some voltage into your chips. There's no fun in overclocking when you fear a voltage limit, and the jury is still out. These chips are a few months in the making, and the voltage issues are plaguing, yes a good number of chips, but that doesn't suggest an overarching voltage issue with a smaller process. Granted, voltage will degrade any electrical component, but I don't think what's being said about the E8xxx voltage is definitive until another 4 to 6 months pass.

Well first of all I like to take good care of my stuff...secondly, I don't even know how to overclock, so I'll cross the voltage bridge when I get to it (I know, I know, I'm on a site called overclock.net and don't know how to over clock a CPU, pathetic isn't it?) Anyway I should be learning soon, all my PC parts are here except my 8400...gotta wait til Friday

I think it's fair to say people have definitely noticed some negative change on their CPUs when pushing the voltage up past recommended max.

On the other hand, people have put way over max on theirs and report no degradation. This is where it can get a bit weird. For some overvolters, one day they say they can run 8hrs+ of Prime no problem and the next (with same settings) it fails after a very short time.

I would hate to get to a stage on mine where it starts playing up and I don't know for sure if its the CPU getting 'flacky'.

45nm's are very fragile with voltage..

Maxishine has just recently sent off his QX9650 for replacment since it died.
