Cadence and Micron Demo DDR5-4400 Memory Module

[RejZoR]

The thing is, we had dual channel since DDR1 till around 2008 when Intel released triple channel X58. It's when clock didn't matter anymore (or at least a lot less). Today, some of us are on quad channel already. My QC setup will have the grunt to compete with fastest dual channels for next couple of years. So, I think that's one of reasons why this chasing for insane speeds kinda slowed down a bit. You need more memory bandwidth, get X99 or X299 platform or AMD's X399.

With all that budget latency crap as basis on higher DDR core tech it is harder and harder to run them beyond quad mode as they differ a lot to gang them in sync. Cheats will be introduced to tame that thus increasing more latency.

Kinda a double edged sword... that is the reason we see minor gain from DDR3 to 4. Is just cheaper to make and offer more density... else... meh.

I'm a bit confused here: isn't AM4 platform supposed to last until 2020? That means i can buy a RyZen CPU in 2 years time and stick it in my current board (AsRock Taichi) and it should work with, more than likely, BIOS updates.

Yeah it is, but many don't keep in mind that the only thing staying the same is the socket, the rest will all be different, hell it's already pretty difficult to upgrade from ryzen 1000 to 2000 or even harder building a ryzen 2000 system with a 350 class motherboard, as you need to update the bios and to do that you need a second cpu that will actually boot on that motherboard, so yeah it might last till 2020 but as years go by it'll get harder and harder to really upgrade, unless you plan only to upgrade the cpu, and even then you'll still have a motherboard 3/4 years older.

I'm already not upgrading past my current gen because 800+ for 64gigs for ddr4. If they don't do something about ram prices, who gives a darn about faster ram?

I'm talking about memory slots, because the guy wanted to retain his AM4/ddr4 motherboard, and upgrade to both ddr5 and new cpu that supports it. So what you said has nothing to do with what I said. AM2 (or should I say AM2+, as I believe PhenomII doesn't work on original AM2) has DDR2, and AM3 has DDR3, and the 2 memory modules aren't interchangeable. You can't drop DDR3 in your AM2(+) MB even tho the chip supports it.

There were motherboards that had both DDR2 and DDR3 slots for both Intel and AMD.

It isn't unreasonable to think that a future AM4 motherboard would support both DDR4 and DDR5 but I think it is much more likely that you will need a new motherboard and CPU.

I know about those but they were pretty rare. And honestly I doubt anyone (board manufacturers) will go down that route anymore. Not to mention AMD definitely wont have both controllers on the chips. It's just a waste of resources.

Here's to upgrading your Ryzen CPU in 2-3 years without changing motherboards.

AM4 was launched at 2017 with a promise to be supported till 2020, if you took attention to your Math classes then 2020-2017 = 3 years, If you bought a motherboard in 2017 then you will still be able to upgrade the CPU in 2018, 2019 without the need to upgrade the motherboard, only a BIOS update will be required.. what happens in 2020 is still unknown. so you got 3 years already with the fourth year is uncertain. Zen 3 in 2020 might come in AM4 & AM5 versions or might only come in AM5 version which BTW might be physically compatible with backward compatibility or might completely loose AM4 compatibility. in either case you will get your 3 years support. at least. as promised.

I smell stuff like running everything in RAM actually becoming a more common reality, due to capacity increases, even with volatile memory.
Of course, that is mostly for serverland and much bigger stuff than someone's gaming computer, but still, progress goes onwards.

This is what 3D XPoint aimed to achieve.

No, but you can drop your AM3 CPU into a AM2 motherboard and it will work just fine. In the same way AMD can release AM5 CPUs witch are also compatible with AM4 mainboards and DDR4, witch means you can upgrade your CPU and later upgrade the ram/motherboard when you want to / can afford it / prices stabilize.

Although DDR5 will keep the same amount of pins and physical size it will not work. There are to many differences to the DDR5 spec.
