Prepare for Over 9000 MT/s DDR5 Speeds with Intel Z890 and "Arrow Lake"

[Woomack]

As mentioned, some RAM manufacturers prepare CUDIMM for up to 9200MT/s on Z890, and I know they tested it on all leading mobo brands (count it as ASUS, ASRock, Gigabyte and MSI, but only some single models). It will be higher, but my sources confirm the initial max is "only" 9200MT/s out of the box. Maybe one of the brands will surprise us with 10k+, but I doubt it will be just after the premiere.
My sources also confirmed that the regular DIMM should overclock higher, above 8400MT/s on an average CPU, and can count on 8800MT/s on most CPUs and the current Hynix A/M IC. It's based on ES CPUs, so nothing is guaranteed. Raptor Lake is so random that some CPUs can't even run at more than ~7200MT/s. My worst 14900K actually couldn't even post with RAM at 7400.

On the other hand, I expect it will be empty numbers again, and the performance gain over 6400-7200 will be barely visible. We can't really see much in synthetic benchmarks above 7200MT/s, so anything higher is expected to be amazing only on paper.

Meanwhile Zen 5 struggles to hit DDR5-6000...

Zen 5 doesn't struggle with DDR5-6000, its the optimal speed of ram to use it with, same as Zen 4.
I wonder how much DDR5 9000 would actually matter for gaming or average use.

Now we're talking! Maybe with this + liquid cooling we can finally cross the +3% gaming performance up threshold over 4800 RAM (with a 4090 on 720p, of course)

 

[Prima.Vera]

Yep. Same as always. Must go really fast to offset the latency increase.

With high voltage increase. Prepare to see 1.5V my guess....

I'm so pumped for 9000+ MT/s. I already have the z890 Apex Pre-ordered.

Wow, I just looked it up, it's 95% the same board the Z790 Encore is, with some very slight changes, some good, some bad. I'd probably have gotten one if time didn't press me as much with my previous motherboard malfunctioning.

No more Intel Foxville NIC is probably the best upgrade here, I see they restored the graphics-related circuitry that the Z790 models don't have too. That's quite surprising, I wonder if there's a high overclock potential for the integrated graphics on the Arrow Lake chips. Unfortunately, looks like they removed the native PS/2 keyboard and mouse ports and are now using a combo port, that's a downside for me. Other specs seem pretty much the exact same, like codec, DAC/AMP, DIMM.2, the voltage probes and general board layout.

Blurbs state 9000 MT/s support specifically with a CUDIMM installed, wonder if support for regular modules without a clock driver is also "8400" like the Z790's. Looks like this was omitted from the page. Once G.Skill releases a 32 or 48 GB Z5 CK kit rated for 10000 MT/s I'm gonna pick one up, since they supposedly work with Raptor Lake as well
