Thought I'd start this off, get your overclock results in here folks!

Memory used = Corsair DDR4 16GB (2X8GB) 3000Mhz C15 kit (£130 at OCUK)
Mobo used = Asus Maximus Hero VIII

Cinebench R15 6700k @ Stock:

Cinebench R15 6700K @ 4.9Ghz, 100 BLCK, default cache (1.4V):

6700k @ 4.7Ghz core, 4.4Ghz cache, 100Mhz BLCK, 1.38V:

Note that this was a very basic overclock, I haven't touched the cache speed or the BCLK- I've seen others scoring 1060+ in Cinebench R15 @ 4.8Ghz but with higher BLCK and tuned cache. I'll tune my overclock at some point and push further.

4.7Ghz seems the sweet spot for my CPU in terms of voltage needed and temperatures. 4.7GHhz is stable at 1.35V and the temperatures reach 81DC in AIDA64 over a 2 hour period. Cooling is a H110I GT.

Wanted to add that I upgraded from a I7 920 @ 3.6Ghz and I'm very happy with my purchase. The majority of the games I play (Arma3, Dayz, WoW) are not very multi-threaded, so IPC is key for me. My minimum framerates are massively improved, power consumption and heat output are way down comapred to my x58 and it's very nice to have SATA3, M.2, USB3.1, PCI-E V3, NVME support etc :)

Bad quality photo of my rig, for anyone interested:

Is 1.35v what people are going for as a safe air-cooled 24/7 voltage on these?

That's "up there" on haswell chips, after a shrink, don't we normally reduce voltage?

As I understand it, for Skylake the CPU voltage and the cache voltage are now linked - so voltage appears higher for Skylake. Something to do with the removal of the FIVR, it was mentioned in some reviews.

The main limitation is temperatures, due to the non soldered IHS.
 
Already have my 6700k, ordering the rest of the build soon :)

Undecided on whether or not I will de-lid. Seeing as people are getting 4.6+ easily I might not :)

Here's the rest of the build, I'm still currently undecided

NH-D15 or H110? Tough choices :confused:
 
Only a question so don't think I'm trolling, but what's the thought process involved here, why you bought 6700k and not a 5820k?

(Maybe this is the wrong place for such a debate :o)

Should be great setup mate :)

Though I'd recommend trying to find 3000Mhz C15 DDR4 instead of 2400Mhz - Skylake scales really well with faster memory. The Corsair kit at £130 is a good deal IMO - though out of stock at the moment.

NH D-15 will be much much quieter than the H110. I'm actually returning my H110I GT due to the annoying pump noise (high pitched bird chirping noise, even on 'silent' mode) and getting a Noctua instead due to this issue.

Yeh I'd rather not get into this here, plenty of other threads for debating this, though I did mention my reasoning behind my purchase in my opening post :)
 
My i7 6700k comes Wednesday. Doing my first Mini ITX build.

EVGA Z170 Stinger board with Kingston Fury Black 8GB (2x4GB) DDR4 2666MHz w/ Phanteks Enthoo Evolv ITX case Titan X. Looking forward to the build.

Nice build by the way Dave :)

I'm guessing you mean this (linky)?

Looks like its the D15 then! Low noise is very important to me, and I really liked my D14 as well.

Very nice system Dave, interesting to see what clocks others achieve on theese. Enjoy.:)

Thanks guys :)

Should be a great system you're building there, Simon ;)
 
Dave, out of interest could you try benching at 4.7ghz please

I was going to upgrade to Skylake but went for a 2nd hand 4790k instead. At 4.7ghz it scores 940

Memory used = Kingston HyperX Grey DDR3 16GB (4X4GB) 1600Mhz C9
Mobo used = Gigabyte z97x gaming 7

Sure.

I also started playing around overclocking the cache - it seems to respond very well to this.

6700k @ 4.7Ghz core, 4.4Ghz cache, 100Mhz BLCK, 1.38V:

Thats a better score than my 4.9Ghz run - seems the cache makes a huge difference.

I need to start playing around with the BLCK also - 200Mhz seems to add some more performance.

Also note I haven't fully tested voltages yet - I may be stable at lower volts, haven't had time to fully test, so many settings to test/play with Skylake :D

Very nice clock m8,

I was eagle eyeing on Skylake launch day and the competitor I bought my 6600k had the 6700k in stock for £264.

I went to read/watch some reviews of it, come back then was out of stock. Damn you TTL with your 45 min video.

Then just settled for an 6600k and bought my motherboard and ram @OCuk

Haha yeh his videos do go on a bit :D

How are you getting on with your 6600k?

As someone that has only gone for ROG boards, I have to say I really like the new colour scheme Asus seems to have gone for on the Z170 boards.

They look much nicer than the standard red and black they tend to use. I'm probably getting older but I find the brash brightly coloured stuff can look a bit childish and tacky.

Nice motherboard.
