I5 8600K Lottery Winner :)

Recommended Posts

Posted · Original PosterOP

Hi All,

 

I have been fine tuning the OC on my I5-8600K for the past several days and i think i have it in a very good spot at the moment. I feel i had a nice draw with this CPU. I have a very stable OC to 5.00 Ghz. During Small FFT in Prime 95 my temps are steady around 75C with an occasional spike to 80c max. This is good right? I've archived all this with only a 1.275 VCore. I plan on going down in 5MHz increments until i break it then stop there to keep it stable.

I thought most kaby lake chips could hit 5ghz pretty easily, am I wrong?

Sure, but not 1.28v easy.

1.38v 4.4ghz skylake id need the same voltage as you for 4.5...

Ouch.

2 minutes ago, catzambia said:

Oof, what's the stock voltage on kaby and what do most people need to hit 5ghz?

Stock varies wildly depending on board. 1.35-1.4v seems to be average, 1.325v lucky, 1.3v very lucky, and 1.28v extremely lucky.

 

OP: What cooler are you using?

I've seen some people getting stable 5GHz at just 1.2V vcore, but yes, this seems like a really good overclock, from what I know. On my boyfriend's 8700K I need 1.3V just to get 4.9GHz and I have no idea how much more juice it'd need for a stable 5GHz. :(

1.3v is still pretty good for 4.9GHz, definitely not deserving of a sad face. I bet 5.1GHz is possible especially considering ~1.45 is the upper limit of safety AFAIK (for non AVX workloads only. AVX workloads (such as p95) are dangerous at that voltage).

Delidding helps soooo much. I delidded my 6700K and it went from thermally throttling at stock clocks to 4.7ghz easy.

it's a decent chip, i wouldn't call it a lottery winner

it's pretty linear up to 5.2

so you are looking at 1.33~1.34v for 5ghz on the 8700k
