Why Ryzen will not support quad-channel?

[brad6999]

Im not sure if this is true or not but ive heard that Ryzen only supports 2 ram slots is this correct?

No, it supports more than 2 RAM slots, but only in dual channel mode.

Ryzen supports 4 slots in dual channel mode like the intel mainstream CPUs. (like 6700K/7700K).
It doesn't support quad channel RAM (to 4/8 slots) like the 6800/6900K

Possibly the X399 platform would support quad channel DDR4, with the 12c/24t and 16c/32t CPUs.

In enthusiast segment the quad-channel has negligible performance advantage over dual-channel (if any at all). Therefore in Ryzen's price segment it would make the platform more expensive for no good reason. However, AMD is getting ready its server platform called Naples featuring as many as 32 cores (64 with SMT) with 8 channel DDR4.

Tri and quad channel memory is pretty pointless on consumer grade chipsets, Intel just tack it onto their high end ones as they are server derived so no effort. If you don't know for absolute certain you need it then you definitely don't.

The upcoming AMD X399 chipset will support quad channel but that will be a chipset that will be more aimed at high end professionals rather than gamers.

can you link me to this info source plz

never mind i found it.... so i will stop my ryzen build now and wait.

It won't be cheap. It will compete against Intel's Skylake-X and Kabylake-X platforms i.e. $1000+ chips.

Yes like muon said it won't be cheap. Rumoured core count (and so far X399 is all just a rumour) is 16C/32T so definitely server/workstation territory. Max clock speed is likely to be a bit lower than Ryzen 7 too if use current Intel Xeon chips with 10+ cores vs thelower core count version. I would expect something under 3GHz but maybe some clever turbo might come into play when all cores are not loaded. So probably not that great for gaming, but should make a great virtualisation workhorse.

it'll be great for workstation applications i.e. what AMD chips have been great at since k7. It won't be cheap but will be affordable.

Intel have never been that good at cpu architectures for intensive workloads, I'm sure it'll be better than those offering's as long as you are reviewing with the correct metrics.

I've seen some benefits but it is very hit and miss - where I really notice it is when running multiple VMs - also seemed to help a bit when I had the GTX780 in but not so much with the GTX1070 not sure why - I think Kepler needed a bit more software "assistance" with more recent games.

I'm not Ryzen biggest fan but I don't see not supporting quad ram as an issue. It's really irrelevant to the majority of applications.
