27 GB/s is actually pretty close to DDR4 already.

in fact it's higher than most... only the top of the line DDR4-3000+ systems will outpace it

Here is a article that covers how fast DDR3 and DDR4 is at what frequencies.

Yeah I noticed. DDR4-2133 is only 17 GB/s, so yeah

That's from Aida64 (my RAM)

Maybe the numbers you have seen are for single channel?

I want DDR speeds like that L1 cache.

 

Hey Intel build me a stick of L1 cache.

That is exactly what it is. 2133 x 8 = 17GB/s. 2133 x 8 x 2 = 34GB/s. Your ram at 2400 x 8 = 19.2GB/s in single channel, or 38.4GB/s in dual. Your write efficiency is quite impressive BTW, 98% efficiency.

Only 24 more SSDs until you have read / write speed comparable to DDR4 RAM!

Gonna need a lot more than 24

The video mentioned an upcoming TR BIOS that allows what he's doing by having an option to bifurcate two of the x16 slots into multiple x4 links.

 

All I can think of is EIGHT X4 GPUS AND MAYBE ONE MORE X16 ONE MORE X8 ONE MORE X4. MULTI GPU CROSS-FOREST-FIRE

Yeah, my DDR4 isn't quite as fast as that NVMe RAID

 

 

Now if my internet connection and bulk-storage hard drives could be as fast enough to make that L1 Cache look like

Something is incredibly wrong with that laptop. Dual channel DDR4 2133 has a peak theoretical memory bandwidth of 34GB/s. I have NEVER seen only 70% write efficiency on dual channel. Slowest I have seen was 90% on writes. Do you have Aida64? I'd like to figure this out for you.

Well I do have 3 sticks of RAM in it.  The original single 8GB stick that I put in it in December 2015, then the extra 2x16GB that I added in October 2016.  Total is 40 GB.

 

 

I'd definitely help if I could get another 2x16GB, and have a total of 64, which is the max the laptop supports.  (I'd have to take out the single 8GB stick.)  I'm just not willing to pay current prices for it.  The pic above shows what I WOULD be willing to pay.

 

You think the third stick is holding back the bandwidth?  But, if I took it out, how would the performance be affected when I'm hitting the pagefile more often?

And yes I do have Aida64 Extreme, although it turns out the key someone gave me was from a keygen or something like that, cause I can't upgrade it to the newest version.  (I have 5.80.4000)

 

 

Actually though, on my next desktop computer(*), I'd like it to support at least as many times more GB of RAM as my current desktop (or laptop), as that desktop/laptop has/does over my dad's laptop that I'd been using until I got said desktop - BEFORE considering things like HEDT or server motherboards.  (My desktop has 32GB, dad's laptop has 2 GB.  32/2 = 16, 32*16 = 512 GB.  Or if you go by my laptop, it'd be like 2GB -> 64GB -> 2 TB.)  No, of course I don't need that much RAM to start with, but I want to be able to eventually UPGRADE to that over the following several years or decade or so, as needed.  (Once prices come down, for example, being able to edit a few full-length RAW 4K movies entirely in RAM would be nice. )

 

(*) - "next desktop computer" - that assumes I get one when DDR5 & PCIe 5.0 are out.  I may be doing an upgrade as soon as this fall, though, because of my current motherboard possibly being dead.  Something got popped off by the VRMs on the back side, and I fear turning it on might kill something that wasn't dead already - system was powered off at the time of the mishap.  Ryzen is under consideration, as is also building a NAS.  Not too enthusiastic about Coffee Lake at the moment, at least because of lack of forward & backward compatibility on motherboards.

Ah, so it's running in Flex Channel mode, that makes a lot more sense. Have you already completely saturated 16GB of ram to the point in which you are swapping over to pagefile? If not, I wouldn't really worry about using the 8GB stick. It begs the question of, what happens when you swap from dual rank, to single rank during flex. I could not find any documentation on that, but I might grab some of my spare DDR4 to test this myself.

I've hit my current FORTY-gigabyte limit several times recently.

 

I don't think I've heard of Flex Channel mode? IIRC I'd thought when you had 3 sticks of RAM in a dual-channel system, it'd run in single channel mode.  Then I had the 3 sticks in this and saw that memory apps were mentioning dual channel, like this &, IIRC, others.  I'm guessing Flex is dual channel when it's using the two 16GB sticks, then when I go above the 32GB into the last 8GB, it goes to single for that portion?  Or how does it work?

That is absolutely correct. The part I am not certain about, is what happens to rank interleaving during the flex. I am currently investigating that part of the equation.

The NVME setup is faster than single channel DDR3 or low clocked DDR4. Dual channel memory configurations can still outpace it handily. So what you read was only half wrong.

I believe the two are interleaved until the channel with the least memory is saturated. Single channel speeds thereafter. If AIDA64 averages the result, then it probably wouldn't be too far from the results your getting.

 

But if you may, please take up the role of Guinea Pig, and test with equal channels.

[Doobeedoo]

That's just simply epic wow so many of those drives. I've planned getting one of those, but heard new series will be revealed soon I guess. Not in rush so.

Here is a update on the official statues of its release, AMD is delaying to make sure partners are ready and to get some last minute bug fixes in.

Still no word on if it's bootable?

The original slide said bootable, which seems to be whey AMD is also waiting on BIOs updates. we have to wait for the official release material to know for sure, and tests.
