So my CPU has degraded.

Well, who knows. Many factors can be involved.

I can tell you that my CPU rarely went over 70c in those 2-3 years and still got degraded so i dont think heat had much to do with it.

Eist and c1e are on as well, my CPU didnt run those 1.44v 24/7.

 

Thank you for you input Undying!

So apparently, your CPU didn't really overheat.
You mentioned that your more regular overclock was 4.8Ghz @ 1.38v but your chip could reach 5.0 GHz.

So the perceived "degradation" you are experiencing occurred at 1.38v during load only, because the power saving feature were still active while idling?

Oooooh nooo! My motherboard is setting the CPU voltage to 1.385V by default!!!:bolt:

Since the temperature was fine, I bumped the voltage to 1.45 to overclock higher! But now I'm just scared c: ........ :leave:

 

trick to keep voltage down : increase vccin

 

Thats a Haswell only option i think.

We dont have it. :/

 

hmm yeah your right

 

I'm a rookie when it comes to OC'ing, but from what i've gathered my mobo gives needlessly much voltage to my 2500k with auto settings and I assume that this could be the case with today's hardware, so you should propably lower the voltage.

So you cant push it through the roof just because the temps are acceptable.

 

Leaving anything on auto in CPU OC'ing is risky actually.

I remember some OC options on mobo's putting 1.425v on some haswell cpu's for an automatic 4.5ghz.

 

bummer

 

My 2500k has as well dropped off to 4.2 from 4.4 same voltage but really no difference I notice.

 

Im still pushing it high, 1.39-1.40v at 4.8Ghz right now. Chip will not hold another year or two if i continue to push it like this....gonna need upgrading soon.

 

My Opteron 185 on his old days used to do 3.0Ghz @ 1.49v ... Now only do 2.930 @ 1.51V and 3.0ghz is impossible, even with 1.55v don't boot. But is like 8-9yr of running O.C.
The OCZ Platinium TCCD still running at 625mhz at 2.9v :wanker: ... DDR1 memorys are bulletproof

 

How long you reckon our chips would last if our mobo supported dynamic vcore and llc together?

 

My X5650 has tanked recently, was a solid 4.4 @ 1.42v no llc. Now I cannot get stable plast 3.5 no matter the voltage. 3.5 @ 1.3v or so atm. I bought the x5650 used over a year ago, and had it at 4.4 @ 1.42 since the day i installed it

 

For all of my 1366 CPU's I had or still have I'm not going over 1.4V with HT on no matter what, tbh can't remember what was the last CPU I was running above 1.4V, even one cherry picked C2Q Q6600 G0 @ 4.2GHz (9x467) I have for years is still going strong @ 1.397V. Also like to keep them below 60C, eventually 65C is max I'm willing to go with HT on and all cores/threads max stressed with something like Prime95. All of them were/are either watercooled, below AIO or under some nice big heatpipe cooler, all in well ventilated cases. Still have in perfectly working order my cherry picked 920 C0 capable for 4.2GHz HT @1.39somethingV, 920 D0 @ 4.01GHz HT 1.25V iirc, X5675 @ 4.6GHz HT (not sure about the voltage, below 1.4V for sure).

What cooling you were using on that X5650? Sure it wasn't raped by high temps and/or in badly ventilated case? Maybe previous owner wasn't paying attention on those things...

 

You're running a fixed voltage?

Wow.... I guess that's why dynamic overclocking/voltage adjustment is good. When idle it runs at 0.9-1v and 1000MHz+ and during load it jumps up to 4.9GHz and 1.46v.

 

Nope

 

Its incredible that you are running and keeping cool Ivy chip at 1.46v. What kinda cooler are you using to tame that beast?

It will not last long at those voltages man, try to learn from this thread.

 

Man my Ivy has been going for a pretty long time now, don't know maybe it's the dynamic overclocking.

It's cooled by a Xigmatek Aegir anyways and is delidded.

 

Probably. Running such a high fixed voltage 24/7 would be insane. Even so, using dynamic voltage my chip still got degraded, slower though.

 

Understand. Seems to be temperature the most though that has a hand in this, as per this article:

Seeing as I'm not hitting 70c+ degrees anyways I think I'm pretty cool. That's what I hover around during gaming.

Most likely if I dial down to 4.8 and 1.4v I would max out at 64-66c I'm pretty sure.
