This entails a tiny integrated circuit (IC) that sits directly on a module’s printed circuit board (PCB). It’s responsible for generating the memory’s clock signal, and these CU-DIMMs, or Clock Unbuffered Dual Inline Modules, are more stable at higher frequencies. This in turn is allowing memory makers to reach new heights, and DDR5-10000 is the next big hurdle.
Corsair is already there, apparently, as evidenced by several screenshots and a short video posted to X/Twitter. The company showed off several CPU-Z screenshots, which touts an upcoming Vengeance kit with an Intel XMP profile for DDR5-10000. According to the screenshots, the blistering-fast memory sports default timings of 48-60-60-157.
A separate CPU-Z window (click to enlarge the above image for the full screenshot, or see the embedded X/Twitter post below) shows Corsair running the RAM at DDR5-10000 with timings set at 48-30-80-79. This was achieved with an ASRock Z890 Taichi OCF motherboard running Intel’s Core Ultra 7 265K processor based on Arrow Lake.
Our Vengeance DDR5 CUDIMM modules can run at up to 10000MT/s, and look good while doing it. Be on the lookout for these sticks to drop in early November. pic.twitter.com/K40L7iHQjn

You can bet that other memory makers are frantically validating DDR5-10000 memory kits of their own, in a race to be first to retail. They’ll have to be fast, though—Corsair says we can expect its DDR5-10000 Vengeance modules to release in “early November.”
