Penguin Solutions launches DDR5-12800 MRDIMMs aimed at AI data center memory bottlenecks
In brief
- Penguin Solutions (PENG) introduced SMART Modular DDR5 MRDIMMs on November 2, 2026.
- DDR5-12800 modules target generative AI and LLM inference workloads.
- MemoryAI, Penguin's CXL-based KV cache server released in March 2026, preceded this launch.
- Q4 FY2026 revenue hit a record $567 million, up 68% year over year.
- Bank of America initiated coverage in October with a Buy rating and $100 target.
How the modules work
Each module multiplexes two physical ranks into a single logical rank, per the report. Penguin said that design boosts bandwidth without the speed penalties multi-rank designs have traditionally carried. That's the company's claim, as reported, not an independent benchmark.
The target workloads are generative AI and large language model inference.
The launch isn't a standalone product, either.
It builds on the MemoryAI KV cache server Penguin rolled out in March 2026. That machine uses Compute Express Link (CXL), an interconnect standard that lets servers tap pools of memory beyond what sits directly beside the processor, and it delivers up to 11 TB of memory. One handles bandwidth. The other handles capacity.
The numbers behind the memory push
Penguin posted record revenue of $567 million for Q4 FY2026, up 68% from the prior year, according to its reported results. Full-year sales came in at $1.73 billion (a 26% increase). AI-related revenue now makes up 78% of total sales, and the company says its order backlogs stretch across multiple quarters.
Penguin also says it has managed more than 100,000 GPUs, logging over 4 billion hours of operational runtime.
Some readers will know the company by its old name. Penguin Solutions was formerly SMART Global Holdings, and the SMART Modular brand still lives on in its memory products (which is why the new MRDIMMs carry it).
Wall Street's read
Bank of America initiated coverage in October 2026 with a Buy rating and a $100 price target, which the bank's figures put at approximately 40% upside. Its analysts highlighted Penguin's dual role: the company designs AI clusters and also supplies the specialized memory systems inside them.
The MRDIMM launch sits on that second half of the business, and it's the memory side that Penguin is now putting front and center.
Frequently asked questions
What are Penguin Solutions' new MRDIMMs designed to do?
Penguin Solutions introduced SMART Modular DDR5 MRDIMMs on November 2, 2026. The modules run at DDR5-12800 speeds, and the company says they're built to ease memory bandwidth bottlenecks in AI data centers, targeting generative AI and large language model inference.
How does an MRDIMM increase memory bandwidth?
Each of Penguin's modules multiplexes two physical ranks into a single logical rank. Penguin said this boosts bandwidth without the speed penalties that multi-rank designs have traditionally carried.
What is CXL and how does Penguin use it?
Compute Express Link (CXL) is an interconnect standard that lets servers tap pools of memory beyond what sits directly beside the processor. Penguin's MemoryAI KV cache server, rolled out in March 2026, uses CXL and delivers up to 11 TB of memory.
