Corsair Vengeance DDR5-5600 CL40 2x 24 GB

[ir_cow]

The buzzword today is Non-Binary, and this Corsair Vengeance memory kit is ready for action! Equipped with a 5600 MT/s XMP profile, using modest CL40-40-40-76 timings, Corsair has a memory kit designed to meet the needs of both Intel and AMD users. Follow along as we test this memory and see how it stacks up to the competition!

Interesting review subject.

Can you offer an insights towards why this memory product is being directed at consumers. Or for that matter expectations for scalability (with poor 3TB HDD but consistent 6/12/18TB HDD directly coming to mind) improving at server memory requirement levels.

The price is actually not bad

 

[dj-electric]

The price is in question mark as a pro.
Seemingly, not so much a pro, not according to etailers.

Price is subjective. The question mark is to represent that. It's cheaper compared to 64GB.

Stuff goes on sale all the time. You can buy used and get combo deals. Unlike video cards, RAM price fluctuates weekly. As long as it's not completely out of line, it usually is neutral aka (Price?)

So…..is a 24GB vid card also non-binary???

Seeing this brings tears to my eyes.

32GB of DDR4 cost me around $300 years ago and now 64GB is $170???

That's a very slow kit, but yes.

Has anyone tested weird combinations of DDR5 modules, such as 24+16 GB or 24+32 GB or 24+48 GB? While not really useful in the real world right now, it would show how mature new BIOS versions are, and how flexible the memory controllers were made to be. Also, a few years from now, some people will be upgrading and rebuilding their systems (notebooks included) and will try to use any memory they find in the drawer or can get for cheap.

In the fully-binary world of DDR4, you could try a strangest mix of 32+16+8+4 GB modules, which includes DR and SR, and there's a high probability it would work at full capacity (even if at lowest JEDEC speed).

It might be of interest to some of you that Corsair also has newer kits that appear to be cut down M24B that go by M16B. I wrote a post about it on OCN a couple weeks back. https://www.overclock.net/threads/o...ability-thread.1794772/page-818#post-29199314. I haven't been able to do hands on testing to see how it compares to its fully enabled counterpart due to the lack of a board but who knows, maybe a review is in order?

 

[ir_cow]

@Wirko I don't have 48GB DIMMs, but I can try 32+24 or 16+24. I think as long as you are using the 24DIMM XMP profile, it probably be okay. Though that config probably comes with other unknown problems. I personally wouldn't go that route.

I spent $500 for 64GB of DDR3 in 2009 and probably equally the same amount for DDR2 and DDR1.

Micron is the worst of the bunch anyways. But if its just a cut down 24, it probably has the same XMP profile out of laziness.

Got this in Akihabara for a friend build , boot up normally on Gigabyte z790M Aorus without BIOS update, though XMP did not apply correct Vddr so it was not stable

 

[ir_cow]

@nguyen For me it either BSOD or showed the wrong amount depending on the MB. No wrong voltage. Does it work now you updated the BIOS?

 

[Dr. Dro]

No, they currently use power of two memory configurations.

24 GB video cards currently have 384-bit memory interfaces, which will translate to either clamshell 24 1 GB (8 Gbit) chips, such as the implementation on the 3090, or single side 12 2 GB (16 Gbit) chips (such as 3090 Ti/4090).

24 GB is also possible to achieve with a 192-bit interface by using the latter configuration in clamshell but that would cost precious memory bandwidth and no GPU currently ships like that.

This memory kit is different because it uses an intermediate 3 GB (24 Gbit) IC which was previously unavailable in any format.

I didn't update BIOS, board came with F3 BIOS, after some BSODs I manually set Vddr/Vddq to 1.2v (it was still 1.1v after setting XMP) and everything works fine (1h of memtest stable)

Just as I thought, these non-binary kits are useless except for a very niche use case of a person who needs more than 32GB of memory, but can't afford 64GB....I can't believe there are resources being used on this basically unnecessary product

The increase in density is always more important at the high end of the capacity spectrum, these enable 192 GB+ kits on mainstream platforms, so you don't need an Intel X-series or Threadripper CPU to exceed 128 GB RAM anymore. Corsair offers a 192 GB kit already, hoping @ir_cow manages to get one in for review:

I could ask nicely, but I don't see how my review would do it justice. What could I say that would make it a review worth reading.

That size is strictly for those doing large data sets. I think I need some better benchmarks that show a benefit of having that much memory. Any ideas?

 

[Dr. Dro]

The only usage patterns that would require this much memory, way I see it, are heavy VM loads with multiple active operating systems, 3D animation/VFX projects (Blender has a few ready to render open movies), or an LLM model (such as Alpaca 13B), other than that I would be pretty fresh out of ideas... as it stands now 192 GB is a looot of memory for a consumer-grade PC

Big scientific databases using IBM software come to mind.

That's a very slow kit, but yes.

Same speed and timings as the kit reviewed. Plus it's going to be rock solid stable @5600Mhz.
