Because the are using their OEM stock for overclocking to make more £££'s.
Pretty sure they said they took retail chips too because they got so few to start with.

And their retail chips stock.
money making for few minutes work and bit marketing like "not all chips can do 5ghz"
My understanding is that it is platform level - ie. all boards affected.
Yeah at 5GHz I'm using 1.325v with LLC 5 which gives 1.296v under load, which is fully stable. I ended up using LLC 6 for 5.2 to stop the droop but I couldn't get it to stick. I haven't seen any evidence of AVX offset being broken - I get 5GHz solid unless I run Handbrake or Realbench at which time it drops to the requested 4.8GHz. I only saw unwanted multi drops when I had gone to 5.2GHz, and only then under AVX loads.
Pre-binned and delidded 8Pack 5GHz chip.
50x 100
AVX offset 2
Vcore 1.325 BIOS and 1.296 under load in Windows (LLC 5)
DRAM 1.35
IO 1.2
SA 1.22
CPU standby 1.2
Current cap 140
Not tried overclocking the ring/cache as 8Pack said don't bother. It's on auto (4.4). Cooling is a 240mm AIO (Fractcal Celcius S24) at the front of the case intaking cold air. Case is a large/open plan Phanteks Enthoo Pro M glass edition with extra intake at the roof and an exhaust at the back (positive pressure). Don't get me wrong the chip is a little monster even at 'only' (lol) 5GHz, I was just playing around. It would have been nice to get 5GHz with no AVX offset as the cooling is well up to the job and I can't see why it's not capable aside from the chip just not being 'properly' 5GHz clock capable.
Temps hover low to mid 70s under AVX stress loads, regardless of clock being 5GHz (AVX 4.8) or 5.1GHz (AVX 4.9), and very occasionally touch late 70s before dropping again. The only thing that seems to change is idle temp, which goes from 24 to 34 if I clock up a few hundred MHz or remove the AVX offset, whether at 1.3 or 1.4v vcore. All temps stay relatively very cool regardless... and that's with the fans and AIO in silent mode.

Then doubt can go higher mate. Imho is better to roll the dice on silicon lottery than spending more money buying a chip knowing can do just 5Ghz.
When i go home tonight I will post my settings, which can be found few pages back.

Well in the first 30 retail units only 3 couldn't do 5Ghz, the rest was like 5Ghz or above. Paying £100 more for that chance doesn't seem too good for me. Bright side is that you got a delided and 1 year warranty chip.
Does anyone happen to have first hand experience of how the 8700 non-K boosts out of the box? I've seen it quoted in numerous reviews that it will boost to 4.3Ghz across all cores, but I'd be interested in people's real world experiences.
Edit: I'd also be keen to know if memory can be overclocked on the non-k model.

To be fair that was exactly my rationale. A guaranteed 5GHz is nothing to sniff at but it was the delid and warranty I really paid for. Not to mention available in stock and only £100 premium over basic retail at the time.
I was all set on an 1800x until Coffee came out. I rarely if ever game these days but I do a lot of multitasking and workstation type loads. Now I get fast single thread speeds for desktop stuff and occasional games and enough grunt to satisfy VMs, encoding etc.
The way I see it, the pre-binned CPUs justify their price by dealing with the de&re-lidding hassle and you also get warranty on the chip.
Depends on the person if they're willing to pay the premium for that or not.
Personally I'd wait until availability improves.

Are you going to switch from Ryzen to Coffe Lake? Surely if you want it badly you can find in available online. I don't know how many chips Ocuk have or they are going straight for binning.
I already have an 8700K waiting for me back home, found them in stock and close to MSRP at a Romanian retailer (but sadly they don't ship abroad). Going to build a secondary system when I visit and pick that one up.
Hey, this is actually pretty big news, sliders from Arm TechCon 2017:
This is for 3rd parties, but I wonder if it differs from their internal timelines.

Here are my settings, except Ring and ram speed give a try to the rest.
AVX Offset - 4
Sync All Cores
Core 51x
Core Voltage - Adaptive Mode
voltage 1.350
offset + 0.05
(max voltage 1.4v)
VCCIO 1.2375
SA Agent 1.15
Loadline Calibration Level 5
Internal Power Managment menu.
IA AC LoadLine 0.01
IA DC LoadLine 0.01
C-States - Enabled.
Let me know how it goes.
I have also set the ring to minimum 40, maximum 48 but work first with default ring speed because Ring overclock adds instability and needs further tweaking and still checking if it worth.
I can go my CPU 5.3Ghz at 1.4v flat, with max 4Ghz ring, but only 5.1Ghz with 4.1-4.8Ghz ring.
So still testing if there is any perf gain between the two settings and how affects ram.
Update
Because received some PMs about the Ring overclock, here is a nice article.
http://www.hardware.fr/articles/970-17/attention-aux-overclockings-automatiques.html
The default is 3.7Ghz on the CFL. Some Asus boards OC it by default to 4-4.4Ghz on the 8xxxK CPUs. Same should apply to KabyLake for those interested.
After that the benefits are application & game depedant. 3.7 to 4.4Ghz ring, some games benefit 3.1% other 8.1%. Also Ring overclock affects stability. So is up to you what you want to gain.
eg my CPU can do 5.3Ghz at 1.4v with 4Ghz Ring, but only 5.1 with 4.1Ghz or higher (having maxed it out at 4.8Ghz Ring atm).
Also 8700K would greatly benefit for higher ring speed compared to a 8600K, because it also had extra L3 cache (12MB compared to 9MB).

Of course you know this do you lol ................ most do R15 1.35v or less 5.1ghz so you push 1.375 or 1.4 I think most will do 5.1ghz..................... Well in my testing they did and maybe I might know......
I don't know if you saw my earlier post Ian but my binned 5GHz chip off you is doing 5GHz at 1.296v (AVX offset 2), 5.1GHz at 1.35v (also AVX offset 2) and then I can't get any further without weird AVX issues (multi dropping down to about 44 even with low temps). I've just left it at 5GHz AVX -2 now. Nice CPU though, and a HUGE improvement over an FX8350.
@Panos Thanks for taking the time to post your settings mate, I appreciate it.

You welcome mate. Craig also had given up hope on his CPU and suddely his chip can do 5.1-5.2 today with those
It always worth the try. When I fine tune the system I will post the new ones. Currently running a lot of gaming benchmarks comparing perf between 5.1Ghz with 4.8Ghz ring and 5.3Ghz with 4Ghz ring. And what effect each has with ram at 3600C15, 4000C17, 4133C17.
Must stay that Z370I Strix is a faboulous board for overclocking, even if just an miTX. roflmao.
Never thought I will ever read that an mITX board is good for overclocking, let alone me been the one writing it.
But it pushes the CPU to it's limits....Suprisingly is exactly the same, with the Z270I Strix for Kabylake, only difference is the shorter inductors. (hence needs thicker pad for the monoblock).
Which make me believe those who were saying that most of the Z270s boards where over engineered and could easily take the 6 core coffeelakes were right.

5g binned here running at 1.296v, will do 5.1 @ 1.350 also, 5.2 not 100% stable even up to 1.450, enough to run games and most benchmarks though. Craps out in prime after 10 mins.
For £500 it runs cool and does more than it say's on the tin, think I've always buy binned and delidded from now on this is my first and couldn't be happier.
