Sorting out the currently available CPUs for Z170/LGA 1151

Blaylock said:

The 5820k is LGA2011-3 so that one is a no go for sure. You need a LGA 1151 CPU like the 7700k you listed.
Here's a list of the compatable LGA 1151 CPU's for your Mobo (and their names).

Getting 4.8 on a Skylake is about as good as it gets on air or water. They weren't particularly good overclockers.

CPU Peeps! Need a little help..

I have a i7-6700k in my FatherTime rig (sig) and I got it pretty soon after skylake launch...

It is probably me, but I don't get much joy out of this CPU It is very temperamental and seems I need a high VCORE to get it to do anything significant 48x+. I am running it on a Gigabyte G1 Gaming 7 mobo. I have a lot more fun with my i7-4790k. I realize that the 6700k could just be an OC dud....

EDIT:
This sub I got 50, but only good enough to get the CPUID and screen shot. It was a race. No way I could run anything.Notice VCORE 1.596

I was perusing some options and seems there are many more processors now, or I had tunnel vision on the 6700k.

Either way what say you? I was looking at the i7-5820K:
https://www.amazon.com/Intel-i7-5820K-FCLGA2011-3-Processor-BX80648I75820K/dp/B00MMLXIKY

or the i7-7700k
https://www.amazon.com/dp/B01MXSI216/

Either of these would work on my Gigabyte mobo? I get confused about the LGA numbers. Its 1151 for skylake, right??

I also don't require the FASTEST cpu. And I've heard some of the i5's are really nice for overclocking. I wouldn't mind an i5 to play with and for points...

Feedback/Comments/Disparagement Please!!!

Thanks!

Cheers!

Delidding will not have much or any affect on the voltage needed to achieve a certain overclock. It only helps if high temps is the limiting factor in the overclock. But some people still do it just to get a cooler running chip even when their temps are in the safe range.

If you are able to get 4.8ghz on 6700k there is basically no reason to upgrade. Yes you might get another 200-300 MHZ tops, but there was practically no IPC improvements between skylake and kaby and on top of that the 200-300mhz (if you get a lucky silicon lottery chip) will be unnoticeable in anything outside of benchmarks.

You are basically throwing 300 bucks at a 4% or less improvement for benchmarks. That is assuming you even get a good enough 7700k to hit those clocks.

If you want to do something different that 2011-3 chip might be more fun. They overclock pretty well and you gain 2 more cores for multitasking. The problem is cost on those motherboards isn't cheap.

For upgrade sake though I would just sit with what you have and wait until the Kaby-X information starts to be released.

After delid I saw a 25-30c Drop across the board and was able to hit 5ghz at temps lower than my stock clock could pull before delid.

25-30c... wow... something else was clearly up if it dropped that much. Typical drops with empirical testing to support it, find around a 10c drop give or take a few C.

Anyway...7700K will get you to 5 ghz... a couple hundred more mhz..but that's about it. As far as fame, etc... what are your goals? You want to wreck modern(ish) 3d? Get a 5960x... something with about ton of cores that clock high. An6thijg from 06 to FS respond to many cores.

I was one of those that did it to get temps down. At stock clocks I was safe, but overclocking quickly pushed it over the edge. After delid I saw a 25-30c Drop across the board and was able to hit 5ghz at temps lower than my stock clock could pull before delid.

They put it through 1 hour... not 24.

I would guess the bin buy doing a leak test. Im fairly positive they don't have someone manually OCing every chip. If so where do I apply? (Na-Mean!) And they probably do a whole sheet at a time. I don't think it's ever to late for a delid, but the bigger question is how much headroom would you gain and is it worth the risk to you?

Each processor has passed an hour of the RealBench stress test at the suggested settings.

It's a manual process. We place chips in motherboards and run an hour of realbench, it's a simple pass/fail scenario. We start testing all chips at the top bin and work our way down from there.
