i7 5820K Overclocking Tips Needed

[InfiniteM]

Hi Everyone,

I've just built my new X99 system and have overclocked the CPU to 4.5Ghz @1.3v.

When i run stress tests at this speed it crashes but in general use (not gaming) it seems fine.

I have dropped the CPU core speed to 4.3Ghz and this passes benchmarks such as Realbench, but crashes when running all stress tests.

However it passes the stress tests at 4.2Ghz, is it best to leave it at that speed? Or is there any way to get a higher stable overclock?

Also does running synthetic stress tests matter?

It's best to leave the overclock at that although that is a unfortunate overclock only way to get higher is to increase voltage and increase the overclock but I wouldn't recommend going pass 1.3V without watercooling

If your cooler can keep up you can increase the voltage a bit more, not being totally stable @4,5 with 1,3v is not super suprising.

I found out my chip crapped at more than 4,3ghz,

I can run 4,3 at anywhere from 1,25 to 1,3v, but any higher frequency doesn't work

Keep the cpu at 4,2 and try lowering the voltage to see how low it will go

Just tried that got halfway through my second RealBench run and it blue screened. I'm going to try keeping it at 1.3v and 4.4Ghz now and test at every stage.

I've tested 4.2Ghz at 1.1v and that is fine and stable.

then keep it there, that's the max for your chip

 

 

5820k's are badly binned 5930k's, and those 0,2ghz won't make a massive difference

Thanks for the info and will do.

By water cooling are you referring to a custom liquid cooled loop or an all in one cooler? Or even both?

[runit3]

Try VCCIO CPU 1.15v, System Agent 1.175v, VCCIN (CPU Input voltage -naming depends on board) 1.875v.

May give you some more stability for 4.5 @ 1.3v core v

[Curufinwe_wins]

That's pretty poor. Maybe I was lucky but my 5820k is straight rock solid at 4.5 1.3 (although even at 1.48V I can't get 4.6 stable).

What speed DDR4 memory are you using???

Both high end dual coolers can take higher voltages and custom is even better depending on the setup

3000mhz but that only works with xmp profiles so dropped it to 2400mhz. any higher without xmp and it fails.

just trying that now.

Those settings have got me up to 4.3Ghz, any higher still isn't stable. Thanks Anyway!
