How realistic is 5+ghz on 8700k?

[Money bagzsz]

As the title says, just looking for some information, if i were to lose the "lottery" what could I expect? It's going to be hooked up to a 280mm custom loop all to itself, i'm also willing to delid it.

 

FYI I live in Australia so ambient temps can get pretty high. Basically all 7 of the builds I've built for friends in the past have all lost the lottery,  atleast according to what's stable to people on the internet, so I have pretty low expectations.

72% for 5GHz according to https://siliconlottery.com/collections/coffeelake/products/8700k50g?variant=224965885964

Most people get 5ghz from what I've seen, I'd say it's 80% or higher (nvm apparently it's 72%, not a bad guess though XD). The lottery winners on the 8700K are the people who get 5.2ghz+

"Most people" is a bit of an exaggeration considering you need a custom loop to cool it off but yeah, since he has one it should be feasible.

Not unless you delid.

That shrinks the niche even more, doesn't it?

A bit, but a lot of people who are into PC building enough to go with an 8700K, water cooling, and overclocking are willing to delid.

realistically you wanna keep ur voltage under 1.35v WITHOUT delidding for 85C load~ on an AIO, that said for 5ghz i'd recommend just getting one off SL delidded.

 

If you are picking one up retail, not delidding, 4.9 is way more realistic than 5.0. It's usually more efficient to run at 4.9 anyway. I remember someone with a chip that needed 1.4v@5ghz and only 1.32v@4.9.

 

I'd say half or more of the 5.0 you see online are not for everyday use. Without delidding, the chances of getting a 5.0 chip under 85C full load is less than half.

Not necessarily, after all they could just go for a higher end option if they just wanted more performance - without running the risk of breaking their cpu. The 8700k is still in desktop territory, albeit at the enthusiast extreme of it. You can still get a decent overclock on it with a beefy air cooler.

5ghz is quite likely, especially with a delis and 280mm custom loop

72% is from 5.0-5.2 so your chances can be higher on getting a 5.0+.

The raw percentages:

5.2Ghz: 16%

5.1Ghz: 27%

5.0Ghz: 29%

4.9Ghz: 27%

4.8Ghz: 1%?

It also means that you'd have to be unlucky to get one that can't hit 5.0Ghz. 1 in 4 chance basically in hitting a dud.

If you delid you have to use a custom cpu plate, right? You can't just use an AIO?

SiconLottary stated that from their experience 72% of 8700k's get to 5ghz, but you'll probably need to delid in order to get it even with a 280mm custom loop.
