Ryzen 9 9950X with 4×32GB RAM

[Toothless]

No need, experience prevails. I have experienced zero problems running 4 DIMMs on Ryzen, regardless of rank. Now granted, I've only done installs with 4x16GB sticks, so there might be a difference with 32GB DIMMs, but I doubt it.

However, the OP has made their choice clear, and that makes our discussion mute, so I digress.

It's hugely different from 16 to 32. 16 per dimm is fairly easy to do up to 5600 on AM5 and 3200 on AM4. Once we bump that up then it's just downhill in terms of bandwidth and speeds.

2 dimm is always going to be best, no matter the platform unless it's one of those quad/octo channel things.

So how about just using the qvl list to use 4 ram stick, problem solved

Before you say that, you should check the maximum speeds with 4 stick.
And yeah, they might work faster than that, might...

Yes, I would consider him the average plug and play consumer. Doesn't know when its wrong and also gives up too easily.

If I get RAM, I sort of expect 'plug-and-play' for the rated speed and really don't expect to have to work to get it to run.

Now granted, I've only done installs with 4x16GB sticks, so there might be a difference with 32GB DIMMs, but I doubt it.

The difference was 600 MT/s for me when last tested 4x 32GB; 5600MT/s compared to the 6200 MT/s the CPU does on 2x 32GB. And before you ask, both kits were purchased at the same time, same Kingston batch number, the serial numbers are only a few digits apart. Quad-rank was even run as one kit per channel, instead of the more common interleaved way of populating the banks.

None of these kits are dual-rank. Running 4x single-rank is electrically only slightly worse than 2x dual-rank.

Good luck finding a QVL that lists 4x 32GB or 4x 48GB with anything faster than DDR5-4800 JEDEC. Not to mention that not everyone has the luck of owning a golden sample memory controller.

If I get RAM, I sort of expect 'plug-and-play' for the rated speed and really don't expect to have to get it to work.

I fully agree.
Blame AMD and Intel for this mess, since they mostly advertise single-rank instead of quad-rank speeds, but DDR5-3600 at JEDEC timings doesn't sound very sexy, I guess. Essentially, DDR5 should not be used in a 2DPC configuration for consumer boards. It barely works on servers with reg. ECC DIMMs. That's also the reason why Threadripper only has 1DPC.

It's especially annoying on AMD's side, since we get also told that there is a sweet spot that is only achievable as overclock. Therefore, everyone and their grandma seem to think that every CPU can actually run memory speeds at that sweet spot.

That is what officially supported speeds are for. Everything else is unsupported by the CPU manufacturer. Just because the motherboard vendor validated a higher unsupported speed for "signal integrity" does not mean the CPU IMC can keep up.

The fine print next to the * never says any OC is guaranteed to work.

 

[Shrek]

Seems to me people tune things till they are stable, but to me this just means on the cusp of failure and leaves no room for safety.

My data is far too important to risk it on a little speed.

 

[InVasMani]

Nothing is really guaranteed below the arbitrarily low IMC support full of stipulations when it comes to system memory.

 

[ir_cow]

If you really really care get a server CPU for Reg-ECC

You need to filter by the last column - Socket Support for "4". The when searching for either 32GB or 48GB, these are the only results for filling all 4 slots.

Oops, my bad. Doing so with 32 and 48gb sticks for ryzen 7000 does give some more options:

I guess Asus hasn't validated as many options for the 9000 series yet. Funny how all the options are XMP instead of EXPO.

 

[R-T-B]

Going back to the original point of the topic, yours is "just" 64GB total, and not 128GB, which is (supposedly) way harder to achieve higher freqs.

Yes, it goes back to single vs dual rank of course, and it's harder to get single rank 32GB sticks (not impossible but harder, most of these dies that can do this are low clocking samsungs that seldom get sold at even 6000).

 

[igormp]

and it's harder to get single rank 32GB sticks (not impossible but harder, most of these dies that can do this are low clocking samsungs that seldom get sold at even 6000).

Are you sure it's not impossible?
Wouldn't a single rank 32GB stick imply that dual rank 64GB ones are a thing? AFAIK, no such module is available on the market yet.

 

[gasolin]

I was only limiting to 64gb but thats what i would use, not that i need it but no more than 64gb

Atm i need to settle with only 32 gb ram, i thing 4gb pr core is okay

4x16gb 6000mhz cl 30 is not possible

Fair, but that's not relevant to the discussion whatsoever since we're discussing 4x high density sticks (so either 128gb or 192gb) configs, which are way harder to push higher clocks.

 

[gasolin]

well isn't it just find a set of 128gb ddr 5 and try it ?

 

[ir_cow]

It very much is possible for both AMD and Intel.

Who you asking? You were just told it's possible by the memory reviewer for this site and you're still going to say no?

I'll do you one better. 4x16 6200 CL26. I'll show you my HWBOT submission when I'm home.

Comment to the video Got it to work with your parameters (mostly) on my Auros B650 with 7950x and 4x32GB=128GB Hynix A die sticks. The only difference is a 0.025V VDD increase (to 1.425V, VDDQ remains at 1.400V) to make it run more stable. 1st time to get 4 stick to post at 6000MT in 6 months!

(not so long into the video that he got it to work)
