Hasn't it been demonstrated that these non-binary DIMMs perform worse than their binary counterparts? I suppose then overclocking thr snot out of it is one way to overcome that disadvantage.

Where has it been demonstrated?

Non-binary modules are available with roughly the same highest speeds or lowest latencies as their standard counterparts.
Yes 48GB modules dont quite go to 8200 like 24GB modules and they lack 6000 CL30 options with 6400 CL32 being available tho i see no reason they could not produce 6000 CL30 either.

Tested against other variants that use different XMP profiles, subtimings and sticks that are from different manufacturers. Apples to Oranges comparison.
I bet if one takes 2x24GB and 2x32GB kits from the same manufacturer and same series and uses on them on the same board to manually set identical timings and voltages then they will perform identically or within margin of error.

This review found some performance and latency penatlies between a 16GB and 24GB kit in gaming.

From that review
"Its primary 36-46-46 timings are hardly different to the 34-45-45 timings of the 2x 16GB kit though. This indicates there are secondary and tertiary sub-timing variations too. That's not unexpected given the difference in capacity."

TomorrowI bet if one takes 2x24GB and 2x32GB kits from the same manufacturer and same series and uses on them on the same board to manually set identical timings and voltages then they will perform identically or within margin of error.

This would also be a Apples to Oranges comparison. Manually setting the timings / overclocking is not the same as buying a retail kit.

Also I think there is two augments going on here. 1# 2x 16GB is better for timings compared to 2x 24GB and #2 2x 32GB is better for than 2x 48GB. They both have the same underlying outcome. Regardless of ranks, higher density has higher (loser) timings. Some of this can be offset by overclocking, whether that is going up in frequency or tightening up the timings.

Dual-rank 7800 is mighty impressive right now. Since I only have 64GB Hynix-M die for dual-rank, I haven't surpassed DDR5-6800 yet. I'll probably get my hands on a 96GB (A-Die) kit soon though.

Edit: Two things to note this press release. Looking at CPU-z, this is just a 7200 kit OCed to 7800 (so not technically retail). Also the MB is using the newest BIOS "Improve system stability and compatibility for the next-gen processors". The latter is not really revenant besides knowing the next gen is right around the corner :)

Nice timings! Could do without the RGB, though (personal feeling). :rolleyes:
It's nice to know you could get up to 192 GB of RAM on a consumer MB, but do the CPUs support it?
Intel's Ark states 128 GB for all consumer CPUs, even for the mighty i9-13900KS.

It's supported after MB update. Intel just didn't update the datasheet since 48GB DIMMs are so new.

Nice! Might consider 2 x 12 GB for my next build (2025+).

P.S. If such modules (will) exist. :rolleyes:

Why not just get far easier to obtain 2 x 16GB kit, dirt cheap.

I'm sure it'll be usable for all three RAM overclockers with cherry picked 13900KS CPU's and $1000 motherboards


For the rest of us, it's a bit silly.

Yeah, it's, probably, the best option. Thought I'd save some cash. Might even need 32 GB if desktop iGPUs will convince me by then.
That Minisforum UM790 Pro does look very appealing. But I'd want performance ≥ RTX 3050, so... I'll just have to wait and see.
