Damage CPU from overclocking and/or too much vcore?

[Ed1]

Today I replaced my 4820k with a 4930k to see if my CPU was the problem. I was going to upgrade to a 4930k anyways at some point. Still having the same problem with Xplane 10.25 and Intel Burn Test in the 16MB /20 run test with the same error message at the end. Xplane 10.25's log file says that my system was out of memory in the last several lines of the file when the crash to the desktop occurred. It's only when I fly a specific aircraft in this game.

That sounds more an more like bad memory module , what size and how many are you running with that setup ?
Is this with new ram in your above post ,32GB of Crucial Ballistix Sport DDR3-1600 ?

I have 16GB (4x4GB) installed. My new RAM should arrive in a few days.

A few minutes ago I ran Intel Burn Test on my mom's computer to try to see if the problem would show up on her computer. She has a Dell with a Q6600 CPU in it. The same problem showed up on her PC as it showed up on my PC in the 16MB 20 run test at the after the last run completes with the "stopped unexpectedly message due to software bug or unstable system." So I guess it's a software bug. It happened in Windows Vista, 7, and 8.1 as well.

Also a few months ago when my system crashed during Memtest86+, timer stopped, no response from keyboard, but curser still blinking, I was using my older Asus P9X79 Pro motherboard that I replaced with another. I had a weird error message issue in Windows 7 with the older board that would frequently pop-up while accessing stuff through the Control Panel with the older motherboard. Memtest 86+ has not froze in my newer P9X79 Pro motherboard, at least not yet. I still have the older motherboard in my closet.

This with her RAM, or with yours?

The XMP settings of my RAM are 1600MHz at 9-9-9-24 2t. I lowered the timings to 8-9-8-24 and Intel Burn Test gave me a critical error message about my system not being stable on the 6th run with a different output result than the previous runs. Is it possible that my RAM is borderline unstable at it's XMP timings or the IMC of my CPU can't handle the XMP settings of my RAM? Also one time memtest froze on me but the cursor was still blinking with this memory with the same CPU at XMP timings. I know that the memory controller of the Ivy Bridge-E officially supports 1600MHz DDR3 but at what timings. I never had this issue with my 3930k or 3820 with Intel Burn Test with my memory at XMP settings.

Ok with my 4930k I was able to run Intel Burn Test on Very High for 10 runs successfully with my memory at 8-9-8-24 but on the 4820k it failed on the 6th run with those timings. Also my Intel Burn Test problem started a few weeks after using the 4820k, it would crash with all cores turbo'd at 3.9GHz and at official turbo settings it would reboot my computer with a message saying that my PC has encountered a problem. This was with the Very High stress setting. Also I tried all cores at turbo synced at 3.9GHz again a couple of weeks ago and my PC shutdown during Intel Burn Test while I was away for a few hours. Also the memtest 86+ freeze problem happened around the same time period that my system experienced these instabilities, 2 weeks after using my 4820k. Can the auto overclocking in my motherboard which took it to 4.5GHz at 1.56v vcore degrade the memory controller in my 4820k in a matter of minutes to the point that even on stock turbo settings it is no longer stable?

I want to add that it was the Optimal Mode in the BIOS that took my 4820k to 4.5GHz and a 1.56v vcore.

This doesn't sound right , I don't know on X79's but my AsusZ77 only has a optimal default option which restores the default values of bios , shouldn't OC anything AFAIK .

Are you having any issues in real world app you use or its just IBT ?

 

[Dave3000]

Alright, today my 32GB of Crucial Ballistix Sport arrived. I'm still getting the same crashing to the desktop with the same airplane with the message saying that X-Plane has stopped working with the new memory. So I think that my old RAM is fine. It must be a bug with the way X-plane or a bug in this specific aircraft itself or my motherboard or sound card but I'm not going to buy anymore new parts as I already replaced the motherboard last year.

 

[Dave3000]

Now I'm not sure what is the bad part, my CPU or the memory or if it even is just that the combination of memory and CPU (IMC is on the CPU) don't get along. I haven't really tested my new CPU long enough with my old memory to know if it was really my old CPU that was the problem. If I only knew that these parts were fine I could have sold them and probably recovered at least $300. Now I have a spare CPU and spare memory lying around.

The only stress test I have issues with is Intel Burn Test 2.54. I have an i7-4820k. In the past I tried to overclock it to 4.6GHz with 1.33v vcore and LLC on high setting and it was not stable. I only had it at that setting for about 10 minutes. 4.5GHz at 1.28-1.3v (don't exactly remember the vcore amount), I didn't have any issues but only tried that setting for 10 minutes. Also one time I set a specific performance feature to on in the BIOS and it automatically overvolted and overclocked my CPU to 4.5GHz with 1.46v and I ran it for 5 minutes at that setting. That performance feature didn't say it would overvolt or overclock my CPU.

Now I'm having issues with Intel Burn Test and I'm not sure if it's because of my CPU not being stable anymore. After the last run in Intel Burn Test I get a critical error message saying something about Linpack binary stopped working, maybe caused by missing executables, software bug, or an unstable system. Also I can get it consistently to show that message after the last run if I run the test at a 16MB size for 20 runs. Also a few times while running this stress test, my system shut down with one time getting a BSOD saying that my system has encountered a problem and will shut down, at stock settings. I can get Intel Burn Test to display that critical error message consistently after the last run on the 16MB test even underclocked at 2GHz.

I can run OCCT Linpack for 6 hours without problems and Prime 95 for 8 hours without problems, but Intel Burn test some times has issues with my system even underclocked.

I don't think it's worth overclocking a 2500k or any CPU for that matter. It can cause system instabilities, data corruption, risk damaging, and reducing the lifespan of you CPU. Overclocking also adds another element to troubleshooting computer problems. Also it takes too much testing and time to test for overclocks that might or might not be stable. In my opinion if you want more CPU speed even if it's not much faster, I suggest just sell your 2500k with the motherboard and upgrade to either a 4670k or 4770k with a new motherboard as Socket 1155 does not support Haswell chips. However if you are going to lose too much money in the process then stick with what you have and maybe upgrade to a faster GPU if you don't have a fast GPU.

Did you get your threads mixed up? Dave3000 has an i7-4820K -- which is an IB-E core . . .

Anyway, Sable -- I could post this afterthought on the other thread "Is it worth overclocking an i5-2500K?"

This is an interesting and entertaining movie:

Get more RAM, and I hope your using SSD as ysour OS drive. gl
