Choosing memory for my gaming pc

Not sure where to put this, there doesn’t seem to be a memory specific sub forum

I’m stuck trying to decide which memory kit would be best for my dualboot gaming/linux powerhouse.

Motherboard is an ASRock Livemixer B650. CPU I’m still deciding between the 7950X3D or the 7800X3D, depending on how much I think I will run dual boot and dive into Linux with some VMs.

I’m undecided between these 3 kits:

F5-5600J4040D48GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-5600 CL40-40-40-89 1.25V
96GB (2x48GB)
AMD EXPO

F5-6000J3040G32GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-6000 CL30-40-40-96 1.40V
64GB (2x32GB)
AMD EXPO

F5-6000J4048F24GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-6000 CL40-48-48-96 1.35V
48GB (2x24GB)
AMD EXPO

Why each:
96GB kit: Obviously for the size, even more so if I end up spinning up some VMs.
64GB kit: Still a decent amount even for VMs, and it goes up to 6000mhz, which 96 doesn’t
48GB kit: Still a good amount of memory, and being 1R might have more potential to go further in the future? Though I wouldn’t make a decision based on the potential for something.

Am I missing something?
Is 5600 still good enough for the 96gb kit or am I loosing to much perf? Can it still be pushed to 6000mhz though?

I’m not on DDR5 nor AM5 at the moment, but what I can tell you from my experience is that you shouldn’t buy memory in hope of overclocking it to reach your performance goals. I feel like r/overclocking makes it seem too easy, but it’s in fact very hard and may not give you the expected results.
What also makes or break memory overclocking is the IC the kit is equipped with. One of those kits might be based on an IC that’s already running as hard as possible and will not overclock properly. There’s also the invisible plague of the WHEA errors that can hide under a system that looks stable.
Go for the tested config that will reach the speeds you need, unless you’re willing to tinker hours on end with memory until is stable.

Of these three I would choose the 64 GB kit, 6000 CL30 is low enough latency to rival 3200 CL16.

Just been looking for 96GB kits for AM5.

The only thing I have seen on a board qualification list was this.

Corsair Vengeance 96 GB (2 x 48 GB) DDR5-5600 CL40

40-40-40-77
1.25v

Yeah, just as with the 48gb kit, I don’t want to buy into something based on its possible potential.

Yes, in that regard, in speed and latency that wins for sure. I just wanted to have those 96gb in case I need more mem when playing on the Linux side.

I also found this kit though:

96gb, 6000mhz, CL30

It’s a bit dicey but I’m a little old school when it comes to latency. Yes, Virginia, latency matters. (Despite what some are telling us these days.) My experience is that Corsair isn’t what they used to be. According to Buildzoid they don’t even bin their chips anymore so you really don’t know what value you’re getting for your investment. That said, the lower latency Trident might look tempting however if you plan on OC’ing the RAM you need to know how flexible it is. A good way to determine the performance score of the RAM is to divide the frequency by the latency. The greater the number the higher the score, the lower the latency the greater the number. High frequency is great but it isn’t everything. I recommend watching some YT vids by Buildzoid and Jayz Two Cents on RAM. I would also recommend taking a closer look at what Team Group has to offer.

What is your budget? Are you willing to manually tune the memory?

There are a bunch of faster, more expensive ,96 GB kits out there, but they are XMP and may not work at their XMP speeds (6400/6800/…) speeds. But they are pretty much guaranteed to work at 6000 CL 30-32 on AM5 with some tweaking. Or if you are lazy, by simply loading the profile and lowering the frequeny if it is not stable. If you can afford one of those 6400 CL32 kits, that is the way to go IMO.

The big question with the 5600 CL40 kit is whether they have Hynix or Micron dies. If the former they can easily handle 6000, probably at CL32 or 30. If Micron they may/may not but for sure only at higher latencies.

of the ones you have chosen… it has the lowest latencies and fastest MT/s.
also stick with 2 sticks… 4 at 6000 can cause issues.

This Hardware Unboxed video is illuminating.

Especially for gaming but Ryzen in general, huge differences in performance. You want 6000MT, right at 30 CL…and capacity doesn’t matter as much for gaming for the most part.

Low 200s. But I can stretch to low 300s if there is a 96GB 6000mhz 30CL kit that will work out of the box XD. I can spare a 100 for a whim and convenience.

Not sure how old the 5600 kit is, but I couldn’t find much info on what is capable of.

Yeah, it seems I’ll end up with that one. I don’t believe my use cases will push past 64GB regularly. I just wanted to get in the 24gb per rank wagon and be a cool kid.

This help me make my final decision. Unless a 96gb 6000mhz CL30 appears before I press the trigger next month.

This one just popped up: CMH96GX5M2B6000C30

It is XMP though, but even with expo there is no guarantee it will work. The only config that is guaranteed it AMD‘s official spec (5200 I believe?) 6000 should be very safe though, and up to 6400 is possible with a good cpu and motherboard.

You say that like it’s a bad thing? :face_with_raised_eyebrow:

EXPO would have a higher probability of working out of the box, as it would have been validated on AMD. XMP at 6000 would most likely work though.

IF it isn’t on the QVL don’t bother gambling. That’s like buying a product with no warranty.

Especially if you’re running with bleeding edge domestic end user hardware.

Personally, I’m not big on early adoption but then… I suppose somebody has to be! :sunglasses:

Hey All, thanks for the input.

I will get this one in the end:
F5-6000J3040G32GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-6000 CL30-40-40-96 1.40V
64GB (2x32GB)
AMD EXPO

I figured that today I’m working with 24 on one system, and 32 on the other. 64 should be enough. By the time by endeavors require more RAM, I will probably also need to update platform and we will probably have 64gb sticks, so no point in spending 2x for 50% extra unneeded capacity and maybe less speed,

It’s not in the QVL though, but I feel like I’ve seen it work somewhere, or it just feels it will lol. ← I have a mini Wendell in my shoulder whispering “its gonna be fiiiiineee”

I saw the corsair one, but its XMP, don’t want to take my chances there, and lately I’ve been having this urge of steering away of Corsair for everything. Something from them just doesn’t feel right to me

I won’t begrudge you for shying away from Corsair. They’re definitely NOT the same Corsair of yesteryears. That aside I still wouldn’t throw caution to the wind in this case. I’m thinking you’re listening to the wrong Wendell. There is a reason QVLs exist. Did you check to see what Team Group has to offer?
