Do all 8700k oc to 5ghz?

post #1 of 9
Thread Starter 
Just reading some reviews and most of them mentire doing 5ghz on 8700k...some at stock voltages.

Is this true most if not all 8700k do 5ghz at stock voltage? If so what on earth do they oc to with extra voltage?!

A lot of these "reviewers" don't know how or have the time to correctly stress test an overclock, so I doubt their results are 24/7 stable.

Most, not all, max? 5.2 or so but remains to be seen and you need to delid etc. otherwise goodbye cooling it.

It's the same process as Kaby Lake but refined.

I don't know why anyone is surprised. Decent Kaby Lake chips hit 4.9-5.0GHz.

I'm actually more interested in the i5-8600k samples seen clocking to 5.4GHz +

There are 4.7GHz Kaby Lake's that do 4.8 on liquid metal.I had one of those.
SL's stats indicated ~4/10 7700K's wouldn't hit 5GHz before they switched their test methods, but the numbers are slightly better with press sampled chips.
It wouldn't be surprising if pretested press samples are at the 50 percentile category at least.

There's a reason why Caseking's pretested chips are sold in 4.8-5.2GHz skews. 5.3GHz+ ones probably go to Derbauer.

With the shortage you can just bin it yourself... sell off any garbage ones

No.

As of now, top bins from Silicon Lottery are around 5.2 GHz for the i3-8350K. It honestly looks like the updated process didn't really improve clock headroom meaningfully, as the i5-7600K and i7-7700K were offered at 5.3 GHz.

I'm running 4.9GHz at 1.4v on a non-delidded 8700k with an ASUS Prime Z370-a.
I cannot for the life of me break into 5GHz with stability on prime95, even at 1.49v it was crashing.

You're probably running into a CPU thermal limit if you didn't delid with that sort of voltage.
