overclocking issue or rotten luck

post #1 of 5
Thread Starter 
Hello all, first time posting here, long time reader/lurker though.

I have a hard time understanding if this was my fault or hardware malfunction.

Here's my story.

I saved for 2 years, I bought my dream computer. (5820k, h110i gtx cooler, asus x99 deluxe, 980 ti hybrid, ssd, the works). I read the forums for months prior to this learning the basics of overclocking and prepared for the day when my system was finally ready. I had heard stories of 5820k's hitting 4.4 - 4.6 ghz with ease, I was ready for mine to do the same.

After lots of testing, I finally achieved "stability" at 4.1 ghz with 1.28v. In the beginning my temperatures were good, 30c to 70c (stress tested with Aida 64), but over time they got worse and worse. I used compressed air to blowout my radiators, fans, etc, to no effect. There came a point where rendering video with Sony Vegas got me to 100c. I took off my OC and decided to just be happy with 3.3 ghz and 1.0v. (Same exact cooler is now in my "newer system" working perfectly, it was not the cooler or thermal paste.) To continue, my temperatures fluctuated greatly day by day. Ambient remained the same, but sometimes I would see 20c idle and sometimes I would see 50c idle.

Fast forward a few days, I'm watching a Twitch stream and my computer powers down with a sort of woooosh sound. It doesn't power back up. I bring it to my friend who runs a PC repair shop and is more knowledgeable than myself. He determines that the motherboard is at fault. My power supply is working fine in a different system. I order the brand new ASUS X99 Deluxe II, as I heard ASUS RMA is horrible and I do a lot of work on my computer, I couldn't have 3 weeks downtime. My friend installs the Deluxe II and my 5820k, the chip is fried. He puts in his own 5820k to test, computer powers up and enters windows. Great, my original X99 deluxe fried my 5820k. I do an Intel cross-ship and receive my new 5820K. -700$ in the hole so far before Intel refunds me. My computer is now working again, on stock turbo settings I believe, CPU-Z reads 3.6 ghz, 1.059v, bus speed 100, 30c idle, 22c ambient.

It is important to know that the only settings I ever touched in the BIOS were CPU Core Clock (4.4ghz max), CPU Voltage (1.3v max), SLIGHT adjustment to CPU System Agent Voltage, EPU Power Savings Mode, Intel Turbo Boost, EIST, C-states, and using XMP profile for ram.

Here are my questions...

Is it simply that I was extremely unlucky and got an "underperforming chip"... then a lemon, defective motherboard... that in turn fried my 5820k? Or could my "Overclock adjustments" be at fault?

Do you have be willing to ruin hardware to do "safe overclocking" aka below 1.3v or is my story one of extreme rarity?

I do quite a lot of video production and editing and will benefit from an OC'd CPU. Please let me know if I went wrong somewhere or if I was just very unlucky. I like to think I understand the basics of OC and I would like to OC again, but not at the cost of 700$ and no computer for 2 weeks.

If I do OC again, do you think 4.0 ghz @ 1.15v is a good starting point considering I am at 3.6 ghz @ 1.059 right now?

Thank you all for your time.

Out of curiosity, how do you guys know that the first board was bad to begin with?

@done12many2

we removed the power supply and attached it to a different mobo/cpu, worked fine.
we tried the asus x99 deluxe mobo with a different CPU, wouldn't post.
we tried a different x99 mobo with same working cpu as the one we tried with asus x99 deluxe, worked.

the x99 deluxe and cpu both died simultaneously. with all the issues I heard of "overvolting" from asus boards, it only made sense that the mobo was at fault.

My ASUS sabertooth x99 just took out my 5820k as well. I picked up an x99-A II Board today and put my old 5820k in it...same boot loop without getting to POST.

This is really a shame...I see lots of similar reports on intel forums as well. I had about 460 days on the sabertooth + 5820k.

The question is, should I try my intel 5820k replacement in my old sabertooth, or just cut my losses and stick with the new ASUS X99A II board?

I wouldn't risk putting a replacement CPU in a series of boards that are known to be at fault.

I got the X99 Deluxe II + my new CPU and everything has been great since. Knock on wood.
