G.SKILL Releases Extreme Low Latency DDR5-6400 CL32 Memory Kit

[Chrispy_]

It'll likely make more sense in 3-4 years, when games start using more RAM regularly. DDR4 didnt really become noticeable over DDR3 until fairly recently.

Yep. DDR4 2133 and 2400 weren't really worth much over the typical DDR3-1866 on sale at the same time and early AMD platform support for DDR4 was, ughhh. I lost track of how many AGESAs AMD put out in the first 6th months of Ryzen.

DDR4's consumer launch for Broadwell-E isn't something I remember having much trouble with, though in fairness Broadwell-E was mostly workstation builds that needed stability for rendering 24/7 so I probably used only 2133 JEDEC timings. Perhaps DDR4 not really being ready for prime-time is why Intel skipped Broadwell for their mainstream 1150 platform? It's odd that only two desktop chips came out and they were practically unattainable even at SI/OEM level.

As you have reviewed a lot of DDR5 tech so far, do you have any information or indications that the Alder Lake memory controller actually does, or doesn't, make use of 32-bit DDR5 subchannels?

Hmmm. I haven't checked. I would say purely by a aida64 benchmark we could see if in fact 2x32 bus is actually used.

D4 4400 vs D5 4400.

Are you suggesting that DDR5 designed to run at 1.4V will fail quickly because other DDR5 not designed for said voltage cant do it?

Yes - because chips aren't designed to run at 1.4V. This is Micron's documentation, and here's what it says:

In all probability SK Hynix and Samsung have the same maximum ratings, however, I can't find their documents publicly available.

Oh yeah Micron IC will crap out at 1.4. The sticks I had didnt like 1.35v.

I've been told 1.4v for Hynix is fine. No idea the long term affect on the ICs are though. So don't take my word as law.

By the time I make a new build in a few years, DDR5 will have (hopefully) matured enough that kits like these aren't considered "extreme low latency".

They're not now.
Extreme is the name, there should be a comma after that then "low latency"

My dell 4800 is running at 6400c28 1t at 1.56v.

With this, no need to upgrade DDR5 then....Can you upload a CPU-Z of it?

1.40 volts, that's not for the faint of heart (and neither for those who just want their RAM and CPU to survive for long).

There's nothing to worry about there

Well it looks to me that it will take another 2 years, until datacenters/server adoption to absorb all the slow sticks and DDR5 to mass produce some decent or EXTREME frequencies.
DDR4 also took 2-3 years, from 2014-15 to 2017-18

Then again there's EUV around which might help a bit.

If 27% more voltage doesn't worry you, what about power draw which is 61% higher?

I mean, ok, these are tested and come with a warranty so they won't burst into flames as soon as you power them on. But you can't run them casually either.

lol, neither of those concern me whatsoever

Well then, I guess that settles it.
