4:02 onwards for the i5-8400 budget boards and 2.8ghz base frequency discussion.

The i5 8600K looks like a decent gaming chip with the 6 cores. Unfortunately the pricing is currently way off - should these not be around the £200 mark rather than £300?
The Ryzen 5 1600 is currently around £180 and offers similar performance, so why would anyone buy the i5 at its current price?

Because they want better gaming performance or dont want to have to deal with ram issues? Throw any 3200+ kit in the z370 and it will just work, no messing needed.

Followed your advice and after succesfully getting 4000 C17 tried 4133 C17 @ 1.396v
Left it running stress tests all night and is stable. Thank you mate

Couple of reasons. Many of us need higher core speed because we play MMORPGs or games that benefit from higher speeds like Crusader Kings 2, Stellaris or Total War.
Yeah FPS counts are same between 8700K/8600K and all the Ryzen CPUs (or my old 6800K) at 2560x1440. But I am amazed how fast it processes the AI turns now on both TW Attila and TW Warhammer 2 (vortex).
So yes, if you do not play games that inherited benefit from high speed CPUs, the Ryzen CPUs are great. Also make sure you buy a good board, and don't cheapen out on ram (3200C14 is must)

Nice one there! Also take care of the vccio and sa voltage, if you left them on auto they might shoot to 1.3v. 1.2v for vccio and 1.25v for vsa or less for 24/7. Dram vol can go for 1.45v no problem with ddr4 and bdie.Followed your advice and after succesfully getting 4000 C17 tried 4133 C17 @ 1.396v

No they aren't auto mate
these were the first ones set to manual.Wrote few pages ago my settings for the 5.2Ghz overclock.

@Panos good point, all of the Paradox grand strategy games seem to mainly use 1 thread, I like Ryzen and such but the single core performance is just not there for a lot of these smaller games.
Also did anyone notice that Coffee Lake availability is really good in some Eastern European countries? I wonder what's up with that.

Yeah, I play a lot CK2, EU4, Stellaris, WOT, SWTOR and TESO. All of them run so much better on the 8600K even compared to my 6700K @ 4.9 last year.
Let alone the 1800X or the 6800K @ 4ghz i had. Saying that, there are current games showing no difference between the CPUs. eg the division, sniper elite etc.
So depends what people do. Rendering on Unity engine with the 8600K is crap. But thats why I kept the 1800X on the other machine to do just that, or compiling.
Some OC advice if you please, chaps...
I was running at 5.0GHz and 1.296v with an AVX offset of 2. I didn’t test without AVX offset as I was using 8Pack recommended settings, albeit at less volts ftw.
After some tweaking today I’m now 5.1GHz stable at 1.35v, but it won’t do 5.2GHz without blue screens even though the temps are only in the 70s. I even tried 5.2 at 1.45v but nope. It seems like it’s the AVX causing problems as the multi drops to about 44 in Realbench even with low temps if I’m running 5.2. This is only a 5.0GHz binned chip don’t forget.
Now I’m wondering what’s better day to day (if I’d even notice any difference lol). Running 5.1 with AVX offset 2, or running 5.0 without AVX offset (hopefully - not tested yet). Temps never go above 75 with my fans on silent either way, so that’s all good.

Wouldn't it make more sense just to run it at 5GHZ and not clock it to the edge?? Surely that gives a bit of leeway for any effects long term??
Include anything based on the Bethesda Creation Engine once you mod the game. It pushes one to two cores more and will tend to use another 4 more at a much lower level.

Yeah, probably. That's a good point tbf, it's just nice playing around to see what it can do. Ian said the bins can generally do an extra 100MHz with good cooling so this fits with that I suppose. I'm back to 5GHz with an AVX offset of 2 at 1.296v under load for daily driving. As you said it's probably better longer term even if the volts were low.
I've never bought pre-binned before, and in a way this clock was 'too' easy (not really a bad thing now I have babies taking up my time). I like playing around lol. Maybe it's time to put the extra money I spent on 8Pack RAM to use and start clocking/tightening those instead.

Prices are higher due to the dolar exchange rate.
From what I'm seeing at those EE retailers, prices are a lot lower due to them having enough supply to meet demand and there's also more competition between the retailers once several of them have supply. Prices at UK retailers should fall soon too once supply improves I think.
I have the same cpu/mobo setup as you. I have found that even with LCC at 5 on the maximus board, I was getting 0.025V drops in voltage under load. I have now set LLC to auto and I am getting 0.015V voltage overshoot, but given that only takes volts from 1.3V to 1.315V it isn't a major problem.
AVX offset also doesn't currently work as expected on the maximus board. It downclocks even under non-AVX loads. I currently have AVX offset turned off and just don't run AVX stress tests.

Did you bought a normal chip or pre-binned? Is it delided?
What are your voltage, SA, VCCIO settins? Have you tried to overclock the Ring?
Whats your cooling and temps?
Soldato
Is this avx issue on all boards or just certain ones?

Why are OC not selling OEM i7 8700k ? But are selling overclocked ones at 5 ghz at £500 ?
