4690k 4.5 GHz Stable, Crashes Watching YouTube

Hi, my friend is having an issue with his overclock on his i5 4690k. He set his OC to 4.5 GHz and stress-tested it for 12 hours (used MSI Intel Extreme Tuner) and was stable through the entire duration. However, he will randomly crash on basic tasks like watching youtube or browsing the internet with no other applications running. If anyone can help diagnose this issue that would be greatly appreciated.

 

 

His specs:

 

i5 4690k

16GB G.Skill Ripjaws X

MSI Z97 Gaming 7 Motherboard

Corsair H80i AIO

Corsair RM 650W

Gigabyte G1 R9 380 4GB

WD Black 1TB

Samsung 850 EVO 128 GB

well its obviously not stable...

one stress test isnt enough to make sure its 100% stable

some times things that arent a stress test will show instability

set it back to stock and see if the problem persists, which it probably wont

so you either need to turn down the OC or up the voltage

What about games? Testing the stability of an overclock includes not only stress testers, but also performing real world tasks. In addition, if it crashes at low loads, I wonder if MSI Intel Extreme Tuner wasn't pushing more voltage to keep the CPU stable.

How was core voltage set during stress testing?  Manual or adaptive?  Was this changed after stability testing?

 

Sometimes a manual overclock will not remain stable set at adaptive without an offset voltage added.

This. It seems likely that it can handle 4.5 GHz, but maybe the the voltage settings are the problem.

Games run smoothly, and if Extreme Tuner was pushing more voltage then it wasn't being displayed as such. Voltage was at 1.210V static.

Voltage is manual at 1.210V since I've had more success on my 4690k @ 4.7 using manual and not adaptive, since adaptive can also give too little voltage to keep it stable.

Then your overclock is simply not stable, even with the twelve hour run.

 

Had that happen with my G3258, and a 4790k.  Thought they were stable, but then noticed they were both hot booting occasionally when unattended.  With the G3258 I just bumped up the voltage from 1.30 to 1.35 and called it good.  The 4790k took multiple 12+ hour stability runs with both AIDA64 and XTU to finally nail things down.

Try 1.280

 

Download CPU-Z and keep an aye on those voltz

That's what LLC is for.

I've had no problem using adaptive voltage and I've been using it for years.

It's not a race to the bottom.

Then it isn't stable. 

Stress tests are only one part of the test, and it looks like the OC failed the other half; Real world use. 

Up the voltage if you can, or lower the OC and test again.

UPDATE: Discovered the issue

 

Turns out he used MSI's OC Genie to try out an oc the board deemed stable, and it also overclocked his 1600 Mhz RAM to 2133 and as soon as reset the RAM back to stock, no issues. This could explain the issue because chrome likes to gobble a ton of ram
