Is this overclock safe for everyday use? (7700K @5.0GHz)

Recommended Posts

Posted · Original PosterOP

i7 7700K @ 5.0GHz @ 1.392V (Despite me putting 1.380V in bios)

 

Temps at 100% load is around 85-88c

 

Don't ever hit those temps during games but not sure if that matters...

 

Or should I just settle for the 4.8GHz @ 1.30V and call it a day?

 

1.392 is the absolute lowest that i've seen it stable @ 5.0GHz.

 

Even at 1.37V I blue screen randomly after days of gaming out of no where.

 

Any advice?

Voltage seems high for 5GHz. It could degrade over time with that.

 

Have you thought about delidding it? Not only will it improve thermals by a lot, but you will probably be able to lower the voltages.

The good question is : how much perf do I gain going from 4.8ghz to 5.0ghz ? and is it worth it ?

How about 4.9ghz ?

I say yes...cause by the time you fry it somewhere down the road...you'll be itching for a new rig anyhow.  I run my 8700k @ 5ghz on all cores all the time...sees +1.4v a lot!  I'm going to squeeze every drop of performance out of it while I have it.  This saves me money in the present cause I don't feel the need to replace it with a 9900k nor 3900x.  When it sh!ts the bed...I'll buy the latest and greatest whiz-bang cpu which will hopefully have far more performance...instead of just incremental improvements.

Ah yes, I have thought about this and honestly speaking am a bit scared of and error on my end trying to delid. But will def be an option in the future once I feel confident.

For 4.9 GHz I was able to get it to 1.345 with temps of 74-77

LOL, Just curious, how long have you had the rig?

 

Thanks for the replies btw ❤️

The rig itself for 2 years.  The 8700k only 6 months...before that it was a i5-8500...which is a fine chip, but wanted more threads for smoother frames.  If I didn't game I'd never have upgraded to the 8700k.

In gaming...nothing you would notice.  If you are using fancy software to track fps and the standard deviation there of...not enough to start a thread that anyone would read.  Honestly I could put my 8700k back to stock settings...and in game I would notice no difference between stock and 5ghz.

I definitly agree. While having +200 mhz @Dmor, you are also going to have your CPU running much hotter +15°C, maybe even +20°C. So, I think the best you can do is to push it to 4.8Ghz, have a little bit less power, and also having a lot less temp.
