Question JEDEC DDR5-5200 modules

[Dave3000]

I will be upgrading to a Ryzen 7800X3D/X670E system and want to team it up with 64GB DDR5-5200 and I would prefer a JEDEC standard DDR5-5200 kit. I'm thinking about getting the Crucial 64GB DDR-5200 kit but I would prefer to get everything from Microcenter as that's where I will be getting my CPU and motherboard and if I can get the memory I want from there as well then that's great. I'm willing to buy XMP DDR-5 at faster speeds than 5200 as long as they have a standard JEDEC DDR5-5200 profile programmed in the SPD of the modules. So does anyone know if Microcenter has the standard JEDEC DDR5-5200 kits available or XMP kits at higher speeds that have the JEDEC DDR5-5200 profile? I'll even go for a JEDEC DDR5-5600 kit as long as it has a JEDEC DDR5-5200 profile.

Given the finicky nature that has been reported for DDR5 kits, I'd look online at what your local Micro Center has in stock and then compare that to the memory QVL for your motherboard. From what I've seen, many of those lists include the JEDEC standard for the compatible RAM alongside their XMP profile speed.

I'm guessing you want the JEDEC standard for stability reasons? Just get any EXPO kit. It should work perfectly for you. But if you don't want EXPO and prefer the kit to work at 1.1V only, you gotta check your mobo QVL and buy only the kits on there for best compatibility.

 

[Dave3000]

Well, one of the motherboards I had in mind was the MSI Carbon X670E. I checked Crucial's website and it shows that the Crucial 64GB DDR-5200 kit is compatible with that motherboard. If I can get an 64GB EXPO kit that has a DDR5-5200 JEDEC profile, I'd consider that as well. I want JEDEC standard modules because I won't be overclocking and just want the least tuning to get things working stable. Sure, I can get an EXPO kit but it might only have a JEDEC profile of up to DDR5-4800 and even though the DDR5-4800 profile should work with the 7800X3D, I prefer to have JEDEC DDR5-5200 for a little more speed than the JEDEC DDR5-4800, as long as it's within spec.

You can run JEDEC but you'll need to tune the timings otherwise you're losing out on 15-40 FPS depending on the game on lows and averages.

Timings are also part of the JEDEC spec, not just bandwidth of the module. For example, if I ran a DDR5-6400 module at DDR5-5200 at 32-32-32, that would still be outside of JEDEC specifications because there is no JEDEC timing of 32-32-32 for JEDEC DDR5-5200 modules even though it would be operating at 5200. As far as I know, JEDEC DDR5-5200 has 42-42-42, at least for the Crucial 64GB DDR5-5200 kit I'm thinking of getting.

Removed earlier post.

I read some of your old posts. You want to pair this system with a 4090 and are gutting it based on silly fears where most have been running 6000 just fine. I'm sorry, but I'm not going to help someone waste their money on high end hardware only to turn around and cripple it with low end RAM. Go buy yourself a prebuilt if you want to waste this kind of money. That prebuilt would be more qualified by the oem than whatever you're frankensteining.

He is counting on the V-cache to shield him from the slowness of RAM. Of course, the V-cache can't do anything if the most frequently used data is not able to fit inside the V-cache. But I guess he must have done his research (probably benchmarks from computerbase.de) and he is reasonably confident that he does not need fast RAM.

AMD Ryzen 9 7950X3D Memory Scaling Benchmark

Pairing fast RAM with a top-end CPU is a logical choice, but what happens when that processor is a Ryzen 9 7950X3D with 128 MB of cache?...

Worst case, OP will lose maybe 10 fps on average, which I guess he is fine with.

He'd lose more due to the slower timing of the JEDEC speed he brought up. The issue I have with geomean scores like this is you have to pay attention to which games were included. There's 2 games that I know folks play, the rest aren't relevant. It doesn't change how it's a dumb idea to spend all that money only to use slow ram. Fine, let him use it, but he doesn't need the x670e chipset when he could go with something significantly less expensive.

What is better in terms of reliability? An Asus X670E TUF or a Asus B650E-E Strix? I was considering an X670E over a B650E because I currently have a B550 and have USB issues with some devices even with the latest BIOS and thinking that if I would have gone with an X570 at the time that it would be more reliable with these USB devices and I read 2 years ago that some AMD motherboards had USB issues and maybe I have one of those boards with the USB issues. I just don't want to risk weird issues and that's why I'm considering a higher end chipset this time. A///, you can't buy prebuilt systems with a Ryzen 7800X3D currently and that was the same case with the 5800X3D, so if I want to get a 7800X3D, I must buy the parts individually and build it or the closest I can get to a prebuilt with a 7800X3D is by having the store's technician build it for me and I just buy the parts I want.

 

[Dave3000]

Does anyone here know if this memory kit has a JEDEC 5200 profile and if the modules in this kit are dual-ranked or singe-ranked? https://www.microcenter.com/product...nnel-desktop-memory-kit-flbd532g6000hc3-black

Only reason why I'm considering a 64GB kit is because I read that currently 32GB DDR5 modules are dual-ranked but with 16GB DDR5 modules I'm not guaranteed dual-ranked these days. I just want the little bit of extra performance that dual-ranked modules give over single-ranked and don't care about overclocking memory so I don't care if dual-ranked modules are harder to overclock over single-ranked modules. I just want to set it up and forget it. If I can get a 32GB DDR5 kit with dual-ranked modules then I would rather save the money and not go for a 64GB kit as I don't see the need for 64GB RAM currently but could use the extra speed that dual-ranked gives.

You can get a SI to build one. Check out powergpu.com. they announced yesterday that you can do a build with the 7800X3D.

All the RAM options for the 7800X3D system I tried to customize are DDR5-6000 at that website. Do anyone of those kits have a JEDEC 5200 profile and are the modules dual-ranked or single-ranked? Having someone build my system does me no good as I'm still in a preference of wanting standard JEDEC DDR5-5200 or faster DDR5 with a JEDEC 5200 profile, not to mention I already have the drives, power supply, and video card that will soon to be replaced with a PNY or Founder's Edition RTX 4090. It's not that I don't know how to build a system, it's getting the memory that I want for the system that's my issue. The company I work for has an IT department but at a different location that my actual work site and I'm not sure if they would be willing to build my system free of charge during business hours, I don't think that would be allowed, especially if I will be using the system for gaming and not for business, as I was provided a work laptop.

Honestly, you are overthinking things.

Get this mobo: https://www.newegg.com/asrock-b650e-taichi/p/N82E16813162082

Specs: https://www.kingston.com/datasheets/KF560C36BBEAK2-32.pdf

You can see that JEDEC profile needs 1.1V

I have not been able to find any module with JEDEC 5200 MT/s profile. They possibly do not exist.

All of them have 4800 MT/s JEDEC profiles.

You can wait for some module to magically appear tomorrow with a 5200 MT/s JEDEC profile but I suspect you will be waiting a long time for that.

 

[Dave3000]

I might just keep my B550 motherboard and 32GB DDR4-3200 CL16 and just replace my 5800X with a 5800X3D. The money I save by not buying a 7800X3D, new motherboard, and new RAM can be used towards an RTX 4090 and I'm still waiting on the Founder's Edition to be in stock. However, if I decide to upgrade to a 7800X3D and an Asus X670E TUF motherboard instead, what is some good quality 32GB DDR5-6000 that is low profile that I can get from MIcrocenter as I'm using a Noctua U12A CPU cooler and want to have all components ready on the same day.

 

[Dave3000]

However, if I do decide on the 7800X3D, I want to get dual-ranked DDR5 modules, but I can't be assured that with 16GB modules but I have a better chance of getting dual-ranked with 32GB modules, that's why I would prefer a 64GB kit. I'm not even sure if the high speed XMP/Expo 64GB kits have dual ranked modules. Does single-ranked vs dual-ranked matter with DDR5 also or did it only matter with DDR4?

Looks like I need to eat my hat or something.

[Dave3000]

This is the kit I mentioned in the beginning of this thread that was considering getting. https://www.crucial.com/memory/ddr5/CT2K32G52C42U5
I think that this is standard JEDEC DDR5-5200 because it's 1.1v, timings are JEDEC for 5200, and it has no mention of XMP or Expo in the specifications for this kit, so I'm pretty sure that it's a JEDEC standard kit.
