is my 2600k about to pop or the motherboard?

post #1 of 5
Thread Starter 
1. Changed my PSU only 3 days ago from a 750w XFX Black Edition to an OCZ ZT 750w fully modular so we can rule out that this is a PSU problem.

2. Changed my ram incase of a bad stick. Read somewhere this can cause random BSOD 124. We can rule out it being a ram problem.

3. BSOD on standard clocks / optimised defaults from the motherboard.

4. Prime with 1792 / 1792 etc ran for only 3hours then BSOD 124 on stock clocks (3.8ghz turbo @ 1.245v. Set by the motherboards optimised defaults not by myself) this was an offset voltage. I'll run this again with a manual 1.245v when I sleep tonight and report back.

5. System sometimes will not turn on so I have to switch off the power supply until the light on the motherboard dies then switch the PSU back on and only then will the system power up. Its done this a lot recently with BOTH power supplies.

6. Overclocks are extremely difficult now where once over I ran this chip at 4.5ghz everyday with 1.32v. Temps were great at only 65c with the very average air cooler I had at the time. I find it difficult if not impossible to keep the chip stable at even 4.4ghz. I did get it stable at 4.3ghz for around 2 weeks without any problems and then it BSOD on me randomly now I can no longer get that clock on those settings. I've decided to just leave my settings stock. But even BSOD 124 at stock is surely an indication of a real problem here. I have followed these guides to help me with the overclocking but I'm just not sucessful.

  • Motherboard: ASUS Sabertooth P67
  • CPU: i7 2600k
  • Graphics: Nvidia GTX 680
  • Memory: Corsair Dominator 2133mhz 8gb / (previously) Corsair Vengeance 1600mhz 8gb
  • Power supply: OCZ ZT 750w Modular / (previously) XFX Black Edition 750w

Not sure if any other hardware should be relevant to this problem.

I will be getting a Haswell chip and new motherboard once Haswell has been released of course but I'm potentially wanting to sell this board and chip to a friend of mine and I dont think its fair to sell them to anyone if they are pretty much useless and going to BSOD a alot.

What do you guys think?

Thanks biggrin.gif

Did the stability issues begin suddenly, or gradually get worse over time?

Are you running the 2133MHz RAM at 2133MHz? Are you sure that bumping this up faster in the middle of diagnosing stability problems is a good idea? What voltage have you been running RAM at?

Just for grins (and not recommending it as a fix here), what happens when you enable PLL overvoltage?

Did you at any point ever stress test the build for stability (12-24 hours)?

Thanks for the reply.

This is something has gradually gotten worse. Like I mentioned I used to run a 4.5ghz overclock and it began playing up so I settled for 4.4ghz and then that became unstable and since then I've tried over and over to get it stable at 4.4ghz again. I got it stable at 4.3ghz for 2 weeks then that failed me and since then I have decided to use stock clocks and been trying again and again to get a stable OC of some sort but I noticed even stock settings are not stable either... well with the offset voltage the motherboard provides.

I decided to run a 1792 Prime test while I was at work today and its still going which makes me very happy indeed biggrin.gif although I adjusted the voltages to manual rather than offset voltage of 1.245 which gave me BSOD within 3 hours. But this manual voltage of 1.245v seems solid. I'm going to leave it running for another while. Highest temp is 42c so I'm certainly not concerned.

I've been running my ram recently at 1333mhz as I read somewhere you should leave your ram at this speed while overclocking. Leaving the ram at this speed hasnt helped me gain stability at all. My vengeance ram was 1.5v which I never once touched. My new Dominator Platinum ram is also 1.5v which again I have never adjusted the voltages for. I have had no desire to overclock the ram. I have however set the memory profile to XMP and the timings have been correct etc. Even then the ram voltage has always remained at 1.5v. The 2133mhz ram hasnt shown any link to the BSOD's as its just as common now as it was with my 1600mhz ram.

Enabling PLL hasnt helped me yet. PLL is on Auto at the moment because of the stock settings.

I'm wondering why my chip is unstable with offset stock volts... C states? but should this affect stock clocks?

I've never ran a stability test for as long as the one I'm running now to check stock stability. 9 hours+ now

This CPU has never really been pushed. The highest OC I had was 4.7ghz at 1.4v but I didnt care for the temps from my old cooler which was 75c so I decided on 4.5ghz

Its worries me how I can barely even get a 4.3ghz OC now which should be a walk in the park but its just not stable at all.

This motherboard has an auto overclock feature which takes the chip to 4.4ghz and this once used to be stable but not anymore.

It is still baffling me why I have to turn off all power to my PSU sometimes before my system will turn on. This is just not normal.

My mate has an ASUS P8P67 motherboard with a 2600k and his everyday OC is 4.7ghz at 1.39v. He's made no changes to LLC or any of that . No PPL or ram voltages... nothing. I took a look at his settings both in the UEFI and AI Suite in Windows to check his settings. All he has changed is the Vcore and multiplier. I asked him to run Prime for me and it was rock solid. This is how my chip used to OC and his still runs like it did on day one. I know all chips are different but his chip is golden me thinks.



OH and Mothow, yes I've seen and read that guide / info. It was the first thread I saw here on Overclockers. I have tried changing C states to help out etc and it hasnt helped yet but I'm going to continue trying of course. Thanks : )

Nice to see the replies flooding in tongue.gif looks like the people here arent as pro as I thought.

Nevermind biggrin.gif found out the problem. If I run the CPU on 2 cores its completely solid. If I run it on 3 cores it boots into windows and runs for a while but random BSOD's and if I run it with all 4 cores it struggles to even boot even at stock clocks soo it looks like some of the cores are knackered biggrin.gif

THANKS FOR YOUR HELP!!
