Share your degradation reports on the 2500K/2600K

Little update as my 2600k is still doing 4.8 under 1.4 volts and is just as stable as day one.I think it sees 1.392 as its highest voltage depending on load.

I can run it at 4.9 ghz but it will crash every once and a while while gaming.

In a week or so I will give it 1.405 volts to see if I can get 4.9ghz fully stable on air.

1.405 is relative low, but i don't think that with 1.405 you will get 4.9ghz stable, if at 1.392-1.4 you get crash

Im at like 1.38-1.392 right now,with the higest iv seen being 1.392.i have all the intel power saving things on and pll overvolt off.it idles at like. 089 volts and this chip did 4.6 at 1.285-1.3 stable

[Demo]

I've seen a couple of people who claim 5.0Ghz stability even at 1.390v

[babalouj]

My 2600K is fully linx with avx stable, prime 95 small fft/blend, and 3d stable (lots and lots of 3d mark and BC2) at 5ghz w/ 1.408V loaded.

I have my 2600K running @ 4.8ghz 1.295V 24/7 since day 1. I don't go any higher because it would require me to enable the PLL overvoltage option and I need standby to work properly. Hardly ever restart my pc...

Was having very random BSOD and had to up the voltage to about 1.310 and 1.315 and still would have BSOD from time to time.

I started from scratch, updated my bios to the 1602 release and tried setting the motherboard options to:
Extreme phase
Extreme (the second option)
VRM @ a fixed 350
and LLC to Ultra high.
Voltage again @ 1.295V and about 1 week later no BSOD....
@ first I though degradation, but now it looks like a bios update, correct bios settings can allow it to run like day 1.

Also, on the strange side of things....when I first got my CPU as was able to boot into windows with PLL OFF @ 4.9ghz, this only happend 1 time, and since then it was 48X...
When I updated to 1602 I was able to repeat the 49X setting, again with standby working (PLL OFF), but only for 1 time. Upon restart, complete failure, 48X it is for my chip!

can you post a sceen shot of at least 5 passes of linx at 4.8 with under 1.3 volts,My chip takes 1.392 to get that and its the best binned chip Iv seen so far.

If you are doing it at 1.295 volts your have the best chip on this plannit.

1.392 for 4.8Ghz is the best you've seen so far ? We smoked our 2600K that one did Vantage at 5.7Ghz at 1.55Vcore... 5.1Ghz Prime95 at 1.45Vcore... There are far better CPUs out there than yours... believe me, but most don't do Linx or Prime95 with them

i think our cpu's are identical, any lower than 1.408 and I get bsod 124

Im actually at 4.9 and on air with closed case etc.but i doubt his chip is prime stable at such low voltage.

Things to note:
Bios voltage 1.295V
Load voltage in cpu-z 1.280V
64-bit windows 7 with HT on.
Speedstep and C1 C3 C6 states are disabled (disabling these also make a PC less stable, IMO...)
This is my 24/7 machine....nothing preped for benching, full antivirus, IE8 with many tabs open, my music in the background, ect...
8GB of RAM, the more RAM, the longer it takes for Linx to test each round (about 4 minutes per round in my case....)
My cooler is the original Thermalright Ultra 120 with a Tricool antec fan @ its lowest setting of 1600 RPM; summer here so temperatures are not that great.
4 internal HD's, 4 external HD's and quite a few other usb devices.
My PSU is rather old and abused. 700W SLI Gamer which I think sometimes could be the reason for my BSOD while under heavy load (Working on replacing it)
I also don't believe much in running benching programs for hours....a couple of rounds can give you and overall perspective of how stable a PC really is.
In my case, hours of Dirt 3 and lots of 1080P movie transcoding with files 10 to 16 GB tells me that my PC is rather stable.
....and then we have my last machine with a Q6600 @ 3.6ghz low voltage, 24/7 for 2 or 3 years. Hardly ever a crash yet not even 10 seconds Prime95 stable.

no SP1 thats why it is so easy to pass and those gflops are super low for your clocks

as for somewhat golden cpu's this 2500k is pretty nice 1.37 for 5ghz, this is also my 24/7 machine as well so no tweaked os or anything just retail W7 x64 ultimate

Alright!
Got the right version of Linx; had to up the voltage from 1.295V to 1.3V.
With Vdroop cpu-z shows it @ 1.288 and sometimes as low as 1.280 while running Linx.

Do LinX 20 runs and report back. Also, that's an awefully long defensive post just to state that you still get occasional BSOD. Not stable...

Also, I get 112GFlops at 4GHz... Not trying to brag... just food for thought.

Nice 2600K chip... doing 48x (HT) with less than 1.3v load.

[zsamz_]

lucky you i need 1.42v for 5.0

This is not the Linx 5ghz club....I posted this to show how what I thought was degradation in my cpu's performance turned out to be incorrect bios settings. And take a look @ the linx club, it's been a mess from day 1 with so many options, settings, linx versions, 4T, 8T, HT on or off (fixed bug....), sp1, avx...

About your 112 GFlops, well, your 2500K = NO HT. NO HT = easier to overclock, bench, and for some reason it scores higher Gflops. Look at the results and the higher ones come from users only running 4 threads or 2500K's.

And not defending my BSOD, just showing that the testing was done in a regular 24/7 machine. A lot of benching results from this site come from people that test with a clean installation of windows and nothing else but Linx and Prime95 loaded.
AFAIK, lots of people are complaining about how the p67 chipset (mainly mobo's by Asus) suffer from very random BSOD even after being tested for hours with both Linx and Prime95.

This is more of an informational thread, not bragging rights, I simply answered the question asked after my initial report.

However, I'll add something else about my PC. Originally I had an Abit IP35 Pro with a Q6600 running windows 7 X64 Pro. Well, I was too lazy to reinstall windows and when I bought the new P67 and 2600K, I simply restarted my PC and watched how awesome windows 7 really is, as it rebooted and installed all my new components.

...Maybe that has something to do with my rather low Gflop results (I've seen some as low as 112 @ 5ghz though)
Apparently this has a lot to do with RAM speed / timings.

[Skratch]

So much for not giving my chip over 1.4 volts for all this time to see if it degrades at that voltage.

Im an idiot and just gave the chip over 2 volts.I put in .600 in the offset voltage instead of .060 and have the LLC set to ultra.system booted with huge red warnings and beeping,I went into bios and cpu was 98c and I didnt even look at the voltage before pulling the plug.

Chip seems like it made it but now my board is not giving it enough voltage for the same settings I had before.

Like llc is set ultra and offset .040 with 120% currant but its only giving the chip 1.320 volts on load when it would give around 1.392-1.405 before.

[Dumo]

Your sandy will be as good as its cooling. Crappy cooler will make the best cpu look like <51X maxed 2600K

[dr_sharp]

I have not had any BSOD under any circumstance with my P67 board. I also took the time to make sure I'm 8+ hrs prime stable. But then again, I am running a relatively low overclock.

[basco]

got 25k L045A848\2267 best out of 10.
did x56 on ud4 b3 and died after 1,6v with -50° to -70°, qpi\vtt up to 1,26v ram up to 1,70v.
no more boot,benched till the end and next day nothing.so the worst degradation-lol.

and i dont know why but sometimes i get 124 blue screen no matter what.can bench and play 2 days in row and then buumm.
reboot and good to go.

Get confi

5.1Ghz - 1.416v



5Ghz - 1.376v

try turning hyper threading on and running 8 threads.Im also running 4 sticks of ram and that is probably killing my overclock and ohh did I mention Im on a 23 dollar cooler I bought from best buy haha,My temps hit over 85c with 1 min of linx!

[Demo]

awesome chip , 1.37 for 5Ghz!
