Intel’s Arrow Lake May Support 10,000 MT/s CUDIMM Memory Speeds

Something to look forward to: Intel is poised to elevate desktop memory speeds with its next-generation Arrow Lake processors. The upcoming Core Ultra 200 desktop CPUs may support impressive DDR5 speeds of up to 10,000 MT/s.

What is CUDIMM?

CUDIMM (Clocked Unbuffered Dual Inline Memory Module) is a new memory standard that incorporates an on-module clock driver chip to regenerate the signal, ensuring better stability at high frequencies. This standard represents an evolution of traditional desktop UDIMM RAM.

Key Features and Implications

The official JEDEC specification mandates a base speed of 6,400 MT/s for CUDIMM. However, all announced CUDIMM kits have launched above 9,200 MT/s. Leaked specifications for ASRock’s upcoming Z890 Taichi board indicate support for memory speeds of up to 9,200 MT/s in optimized configurations.

Key Points to Consider:

Intel’s LGA-1851 Arrow Lake socket will support CUDIMM via a “Gear 2” mode.

Motherboard manufacturers are gearing up for CUDIMM.

Running at DDR5-9000 speeds and above requires substantial 1.45-1.5V DRAM voltages.

Excellent cooling solutions will be needed to accompany these high-performance modules.

Conclusion

While CUDIMM offers incredible bandwidth potential, there are compromises. Intel’s Arrow Lake may support 10,000 MT/s CUDIMM memory speeds, which could further widen Intel’s lead over AMD.
