But SS was right about Zens IMC being naff (Although he explained himself terribly IMO), but I said the same at the time.

Because as I stated before its on the cusp of where it DOES start to matter... Fine for now but maybe not so great a few years down the line. Lots of people touting ryzen as an intel enthusiast line competing product...its looking like it lacks in some area if people want to claimthat

how does `naff` mean it can use 2666 ram? JEDEC spec is 2133 which skylake uses
does that mean skylake IMC is also `naff`

Skylake does 3000Mhz guaranteed, I imagine Zen will do the same. Non issue really.

says the highest intel support is 2133 - that's the makers `guaranteed` speed

I wish you'd stop saying JADEC.

CPU vendors putting official support is a lot different than the motherboard manufactures putting OC speeds.
Officially the IMC's are always rated at a lower speed, but the boards tend to put whatever RAM it can run as an OC. If MSI's put 2666MHZ or whatever, it's likely because the IMC's not of the same quality. I personally don't care, but it's pointless to pretend.
Bloomfield only supported 1066 MHz DDR3. Everyone used it with 1600 MHz DDR3. "Max supported" RAM specs are always bogus.
2666(OC) for DRAM. That's likely as good as it gets.
Called it...

Right ^^^^ max supported RAM on my DC is 1866Mhz... i'm running 2400Mhz....
------------
All of this 'RAM speed relative performance' is completely a none issue anyway, it is irrelevant.
The Only thing that matters is the end IPC, its outright performance, if Zen can achieve the desired performance with slower System RAM speed then System RAM speed is just a number with no meaning.

Indeed. And that's why at the moment I wouldn't be drawing too much from the 2666 figure of a specific motherboard tech spec. Maybe it's the motherboard that is the issue?
Caporegime
Why would it be the motherboard that's the issue when they've got Intel MSI boards stating 3600+?
And the motherboard advertised in the link says 2666 is an oc speed (and apparently the highest the mobo maker is willing to advertise..... ) Which means the max 'Official' speed will be 2400... Z170/270 boards regularly advertise much higher oc speeds for ddr4
Caporegime
The CPU vendors listing is different to what board vendors put.
Thus far SS's claim is sustained and supported by vendors.

If Intel thought officially supporting higher clockspeed DDR4 was worth it with Skylake and Kaby Lake they would - they obviously thought it was not worth the effort anyway.
Most systems Intel sells will be running RAM within spec so unfortunately for some here even the Intel CPUs you use are most likely to be configured with much slower RAM clockspeeds than in your modded systems.
It's now become maximum overclocks E-PEEN again.
Moreover unless we have a clearer view of the Ryzen cache system in real world scenario,just looking at the DDR4 clockspeed means nothing especially if AMD has implemented a far more efficient memory controller.
OFC,AMD is DOOOOOOOOOOOOOMMMMMMMED!

It's not the same motherboard though is it?
Until MB designers get used to the IMC on the CPU initial designs won't be the best possible.
Caporegime
There's no reason to have to look for reasons AMD might achieve higher memory clocks.
It's an almost none point.
Who cares if it's only 2666MHZ. If that's the max, that's the max.
SS made a claim.
Thus far it's holding up. That's basically it.

'Terribly?' All I said was I'd heard it was fairly weak...
Which turned out to be true. The only terrible thing to happen was the amount of people that got up on the defensive about it.
Without trying to throw salt on this, motherboard design is only going to net you so much. 6 or 8 layer boards may get you a little more, but I can't see Ryzen officially supporting more than 2800mhz TBH.

I don't know why this even matters?
Again, if Zen gets the desired performance with just ####Mhz of system ram or ####Mhz the point surely is its outright performance compared with the competition, if it can achieve that with slightly slower RAM then that RAM speed is irrelevant.
Its more hot air about nothing. Straw clutching before we even have the facts.

He/she apparently doesn't read/ or agree with link he/she post what makes you think they would know it's JEDEC
