Share your degradation reports on the 2500K/2600K

[Demo]

Wanted to make this dedicated thread to degradation reports/stories that you have on the 2500K/2600K.

Even if your processor has not yet degraded feel free to post your record here so that you can comeback to it later on.


Maybe we could use this format;

CPU:
Vcore(bios):
Vcore(DMM):
VTT:
vDIMM:
PLL:
Mobo:

I'll start with it..
CPU: 2600K
Vcore(bios): Normal using +0.115v offset
Vcore(DMM): 1.454v loaded
VTT: 1.120v
vDIMM: 1.520v
PLL: 1.600v
Mobo: Gigabyte UD4-B3 F3D bios

Comments:
I've had this chip running for about 2 weeks now and there seems to be no degradation yet at these voltages, Now I've went down to 4.5Ghz at 1.352v.
Gonna observe in like a month if things go down south.

IF im understanding this thread at all, why did the above poster "POST" if there was no degration???

Im @ 1.435V for a 24/7 OC of 4.85GHz on water cooling.... No issues as of YET Crossing fingers chip will last another 6-7months!

I may have titled the thread incorrectly but feel free to post if you dont have degradation yet, this will serve like an online record.
Falkentyne has degraded his chip even at 1.260 as he says.

Yeah if you've been at that vcore for awhile at full load, I think you *will* see degradation on your minimum vcore you need for stability. You may want to retest your lower overclocks to see if the minimum vcore has risen on any. I'm busy beating the living hell out of my first 2600k by running it at 5 ghz 1.51v load HT on (I was at 5.3 ghz HT off 1.59v for a few days till eventually Black Ops would BSOD before being able to load a map); trying to see just how much abuse and torture the chip will take, and how much it will degrade completely, as well as at what voltage any futher degradation will stop.

And I'm not even degrading it with prime (it's WAY too hot to run prime at those voltages, anyway); it's just degrading using windows or playing bad company 2 or black ops or other games, and the temps are no higher than the 70's....

Once that's done I'll retest at 4.5 to see how hig h that rose, too. Last test at 4.8 ghz would BSOD in 20 seconds with prime small FFT at 1.392v, while 4.7 was solid. I don't care if I kill this chip; I still have my other one that can do 4.5 ghz at 1.260v load 12 hour blend stable, but even that degraded some...used to do 1.236v at 4.5 ghz and 1.416v rock solid at 5 ghz....now needs 1.440-1.452 at 5 ghz....

6 weeks at 5ghz 1.55v so far no issues. 2500k, have been running lots of blend tweaking memory (vccio 1.13, vdimm up to 1.7). Watercooled, maxing out at 70c prime 81c linx.

your sir, HAVE BALLS! Im on highend water and I wouldnt ever feed these fragile CPU's 1.50++

[Origin_Unknown]

2600k - gigabut ud4 w/f3 bios .... no overclock :P

[PiLsY]

CPU is poor anyway - if it degrades its an excuse to have another go (maybe 2600k this time). Its stubbornly refusing to show any signs of problems though . 3.95ghz stable stock cooler stock vid (1.23v) - pants!

Falkentyne has degraded his chip even at 1.260 as he says.

My CPU didn't degrade BECAUSE of 1.260v.

It degraded from 1.236v to 1.260v (for 4.5 ghz) due to Prime and game tests (black ops/Bad company 2) at 5 ghz 1.404-1.440v. The CPU had previously been a rock at 1.236v at 4.5 ghz as long as I never went to 5 ghz. And 1.404v used to be stable at 5 ghz, now it needs 1.440-1.452v, and this affected the lower overclocks also.

BTW my first 2600k is degrading fast, but i'm doing it on purpose. Some HT off game tests for a few days at 1.59v at 5.3 ghz, and long term gaming at 5 ghz 1.52v ht on. Trying to find exactly how long and at what range it will happen.

4.8 ghz 1.39v BSODs instantly in prime now. 4.7 ghz doesn't, though.

Once I've burnt this chip to a crisp, I'll hopefully know what to do to prevent the 2nd one from ever needing more than 1.272v for 4.5 ghz 12 hour blend, but if THAT Happens, judging by both chips having the same frequency/MP walls, it will be almost identical to how the first 2600k performed when brand new....

Is there a link to intel stating what the max operating vcore of the 2500k/2600k chips?

http://ark.intel.com/Product.aspx?id=52214
I've looked, but no vcore is mentioned. Am I missing something? There's no "vid voltage range" like in other CPUs listed on the same site.

Edit:

So I came across this quick thread on another forum basically stating there IS no safe "range" standard set by Intel. Each chip is unique.... a unique snow flake... or some BS like that...

http://www.overclock.net/intel-cpus/...d-voltage.html

I guess this is why the thread is here.... I still have no idea where people are getting 1.38 or 1.4v as "safe."

I think some chips will just die early, others will run strong with no issues even at voltages above spec. I have pwnded quite a few chips waaaaaaaay above what is considered safe for a couple months now with no issues, maybe just lucky IDK.

I also think sometimes people make changes to OS, drivers, maybe change out vga, or other hardware, bios's etc. and one day the system doesnt run stable at the same voltages, they say "my chip is degrading". Just my opinion.

Default voltages everywhere else.
Mobo: Asus Sabertooth

Report: No degradation thus far. 8+ hrs prime stable and LinX w/ AVX 20+ runs stable. Running SMP F@H 24/7 for 1 week so far. Plan to run at these setting until water gets here. Once I have water I plan to do between 4.5 and 5.0 24/7, but I will update here when it happens!

[dr_sharp]

Does anyone know where to measure Vcore via DMM on the Asus Sabertooth?

[Skratch]

Iv been running 1.5 on load with no degration at all for 3 months now.

[Falkentyne]

Surely that's NOT on air cooling....

[Skratch]

Surely that's NOT on air cooling....

I just hit 98c for 10 min stress testing it on AIR lol,closed case also!

[Skratch]

[Falkentyne]

You've had it at that vcore for 3 months?


When you first bought the chip, what would happen if you tried to use something like, 1.47 or 1.48v for full load?

Even though Mine's a 2600k with HT, I'm seen some pretty hefty degradation just in the last couple of days at 1.52v...

[Skratch]

I run the chip with all intels power savings on,like on idle its at 1 volt and depending on how much load it will go up to 1.528 volts.I just ran a 32m pi and it never went over 1.44 volts.

This chip was always a 5-5100 mhz chip as it would hit close to 97c at 5.1ghz.

Its been overclocking exactly the same as it was when I first got it.

This is also with 4 sticks of 2133 ram for 8gb and 1.65 on the memory

edit here is what it looks like with no load.You sure its not your mother boards caps that are dying.

So what do you plan to do to prevent it from degrading ?

[Skratch]

Now you guys got me pushing this thing again.Im going for another max 3d attempt lol

[dr_sharp]

Hey, every overclocking thread needs a guinea pig

[LagunaX]

I don't think a lot of ppl will have problems with load temps less than 80c and vcore at 1.4v or less.
Yes for some that will mean running at 4.6-4.8ghz instead of 4.9-5.0ghz but then again Ivy isn't too far away...
