Prepare for Over 9000 MT/s DDR5 Speeds with Intel Z890 and "Arrow Lake"
Intel's upcoming Core Ultra 200 "Arrow Lake-S" desktop processors will herald a new wave of overclocking memory kits as the architecture is expected to support even higher memory speeds than the current 14th Gen Core. The product page of an ASRock Z890 motherboard lists out maximum memory speeds for various DIMM configurations. The most overclocker-friendly config—1 single-rank DIMM per channel—sees ASRock mention support for DDR5-9200+ (OC). The fastest DDR5 OC memory kits in the market are DDR5-8600, and over the Summer, JEDEC announced standardization of high frequency DDR5 configurations, including the likes of DDR5-8800. Such high frequencies require the DIMM to feature a clock driver.
Those looking for high capacity memory configurations have big reason to cheer. For two single-rank DIMMs per channel, or one dual-rank DIMM per channel, the motherboard's product page mentions an OC speed of DDR5-6800+. This should be a boon for those wanting large memory capacities such as 96 GB or 128 GB using dual-rank DIMMs at reasonably high speeds. Even the densest memory configuration, two dual-rank DIMMs per channel, has a maximum OC speed of DDR5-5800+. This should allow users to approach the platform's maximum memory capacity, such as 256 GB using four 64 GB dual-rank DIMMs, or 192 GB using four 48 GB DIMMs, but at much higher speeds that what the current platforms are capable of.

On a different note… hey vegeta what does the scouter says about its memory speed? It’s over 9000!
When there ASRock Z790I Gaming WIFI on general default settings in the bios, can't do 8600MT/s like they advertised....??? Best was 8400 stable... this was with multiple memory brands....
I evening purchase V-Color 8600Mhz, memory, that they advertised it would work with ASRock Z790I Gaming WiFi..., it was all over there website.:(
1DPC 1R Up to 7400+ MHz (OC), 4800 MHz Natively.
1DPC 2R Up to 6000+ MHz (OC), 4400 MHz Natively.
2DPC 1R Up to 6000+ MHz (OC), 4000 MHz Natively.
2DPC 2R Up to 4800+ MHz (OC), 3600 MHz Natively.
That's +1800 on 1DPC 1R and +800 on 2DPC 1R. That's a pretty big jump from Raptor Lake.Maybe your IMC can't handle it? That's always the tricky thing with memory: CPU, sticks and mobo need to be able to handle a certain speed. You'd have to try multiple CPUs to be certain it's the mobo.
Low capacity dimms only and single/dual slot only. :)
DDR5 RAM is known to get unstable at rather moderate temperatures in the mid to high 40°Cs. All those people running 7600MHz+ stable (I mean *really* stable and not just able to boot) on Raptor Lake had an ASUS APEX (ENCORE) mainboard, an open bench table and active/liquid RAM cooling employed.
If anyone believes, you can simply plug & play 9000MT/s memory then you're in for a pretty rude awakening. My own ASUS ROG STRIX Z790-E was only able to run my (now sold) 32GB Corsair 7200MT/s kit at 6800MHz max (Prime-stable) and my current 64GB kit that is rated at 6800MT/s is "only" able to operate at 6600MHz with a slightly increased voltage from 1.45 to 1.47.
I would advise caution and to not expect any miracles. The thermal limitations are real and you will most likely still only be able to run 7600MHz+ on ASUS APEX exclusively (or on two DIMM slot boards of other brands).
I do have some Bitspowers LN2 heatspeaders. Currently looking for a waterblock that fits or I'll have to drill some new holes to fit existing ones I have.
Couldn't care less myself as price will be sky high and timings terrible. I'd be sticking to good quality 6400/7200MT/s memory at lowest latencies available.
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.
