Not in any serious workload you don't. Not talking about games, of course.

Yeah. Rock solid.

I'm not sure why you would even doubt that. Because your Ryzen can't hit 4 GHz stable?

Plenty of people hit 5 GHz on 7700K without delidding. Delid can help with temps but it's doable without. Maybe look in the 7700K thread.

My contention is that adding two cores to the package is going to mitigate some of those process gains in terms of power and thus thermals. 5GHz will, in my opinion, again be the province of delids and custom loops and the tap out point for the majority of setups. I'll be happy to be wrong, but I'll need to see proof in practical testing before I'm sold on 14nm++ being so revolutionary.

Not really. I've hit 5 GHz on a 7700K no delid using a 80$ AIO
I hope that translates to increased clock for coffee lake.thumb.gif

It only sucks that i was about to build the 7700K build now with new stuff coming i have my computer parts (Case, AIO, PSU) sitting for the Z370 itx build now

What sort of stability testing?

 

I won't discount the silicon lottery, but your sample size of one does not a universal fact make.

 

Edit: Scrolling through the information in Darkwizzie's KL OC thread, I'm seeing that the majority of chips at 5GHz or better are delidded. Again, I'm not discounting the possibility of lottery winners that don't need a delid, but I am saying that these chips are not standard.

Well, you can lower PPL voltage to reduce temps alot. I've hit 4.8 GHz on another 7700K using cheap air too (Scythe Kotetsu). I'm sure it would hit 5 GHz with better cooling like the other 7700K I overclocked.

Prime95 and LinX.

Most people just settle with 5 GHz I guess, delid or not, it's doable on most regardless (if you know what you're doing). It's a nice number. Just like 4 GHz on Ryzen. It's doable in most cases. From my experience 7700K hitting 5 GHz is more normal than Ryzen hitting 4... The 1600 and 1700 I tried maxed out at 3925 and 3950. 4 GHz was never totally stable (Maybe if it was my own build I would have bothered using hours and hours to optain it, but it was not). Just like most Ryzen reviews, they use Ryzen Master or change multi and run a few benches, never test for totalt stability - That's not how I overclock.

Have there been any comments from Intel about putting better thermal compound under the lids of the new CPU line? Those 2 extra cores are going to produce more heat, and if they put the same stuff under the lids as they did with Kaby, they're going to run very hot, which means we probably won't be OCing these very much on air.

I'm thinking about upgrading, but if Intel doesn't put quality thermal compound under the lids, then I'm probably just gonna wait for the 10nm chip, which is likely to run cooler.

I've seen temps for kaby with no delid on air that run even hotter than my old Sandy Bridge would run under loads. I'm talking Sandy Bridge OC'd to 4.5 on a 212+ cooler running at lower temps than kaby @ 4.5ghz on the same cooler. Sandy Bridge runs cooler than Kaby with no delid? HAHAHAHHAHA. That's horrendously pathetic.

If it wasn't for the fact that Zen processors also run hot, and don't OC very well, I'd have bought one already. It's almost like both Intel and AMD are conspiring to screw OCers. Intel should at least put better thermal compound under the lids of the K models. I'd rather pay Intel $10 more than the current price for an I7 K model that I don't have to freaking de-lid.

I don't think Coffee Lake is going to be that much better over Broadwell to justify an upgrade, anyway. Going from sandy, or ivy to coffee would be a considerable upgrade though.

Sandy bridge is only 3.40 GHz then kaby lake is 4.4 GHz on 4 core load.

Which goes further into the point I was making. SB OC'd by a considerably higher % margin still runs cooler than Kaby OC'd at a lower % margin. On average. Using the same cooler.

SB is considerably slower than KL when both are at the same clock, not sure why this matters
