Mar 28, 2026: Memory price and availability continue to be a challenge. We have once again been forced to increase system prices due to the cost of memory. Currently, the cost of quality memory (DDR5-5600/5200 UDIMM with ECC) is around $370 per 16GB (as of this week). Keep in mind the same type of memory costs around $75.00 in the fall of 2025 (a 5X increase). The price increases seem to have helped availability a bit. While memory availability is still spotty, it does trickle into the reputable vendors we use. With patience, DDR-5600 can be sourced; if time-to-delivery is more important, DDR-5200 or DDR-4800 may be a better option. Due to demand, the price for the slightly slower DDR memory is the same as the faster version, so it comes down to availability and delivery time.

To help offset the increased memory cost, we have added a processor upgrade for the Limulus HPC 132. This system has less total memory (128 GB) than the next level Limulus HPC 232 (256GB) and can now be equipped with the larger cache (96MB) Ryzen 7 9800X3D processors.

This price increase spans the entire market from notebooks to PCs to servers. Please contact us before placing any orders. We can work with custom memory configurations to help reduce the cost of the larger systems.

Nov 26, 2025: Large price jumps in all systems due to "AI memory madness" in the market. Prices for memory have jumped 2-3 times since October. Availability is also getting difficult. Hopefully this market craziness will settle down by next year. Please contact us before placing any orders.

Oct 13, 2025: Next Gen Edge computing is here! AMD-based Ryzen Zen-5 systems are available! All systems include DDR5-5600 ECC memory, updated options, and offer X3D processors with additional cache. The entry-level Model 132 comes with 128 GB of total memory and four Ryzen 5 9600x processors (upgradable to 12-core processors). The mid-range Model 232 starts with four 8-core Ryzen 7 9800X3D AMD ZEN-5 processors (total 32 cores) and 256 GB of DDR5 ECC memory. On the high end, Model 1232 provides eight 8-core Ryzen 7 9800X3D AMD ZEN-5 processors (total 64 cores) and 512 GB of DDR5 ECC memory. Upgrades to 25 GbE, extra memory, and 12-core processors are available. And, like all Limulus systems, each personal cluster runs quietly and only requires one power receptacle.

Oct 22, 2023: AMD-based Ryzen Zen 4 systems are available! All systems include DDR5-5200 ECC memory, updated options, and more. Models 222 (256 GB), and 1222 (512 GB) come standard with 8-core Ryzen 7 7800X3D processors; an upgrade to the 12-core Ryzen 9 7900X3D is available. The entry-level 122 comes with 128 GB of total memory and four Ryzen 5 5600 processors (processor upgrades up to 12 cores are available). Zen 4 Hadoop/Spark Data Analytics systems are in the works.

Mar 18, 2021: Beowulf and cluster maven Jeff Layton wrote a great article entitled Desktop Supercomputers: Past, Present, and Future in HPC Admin. In the article he discusses Limulus systems as a current option for desktop (actually desk side) supercomputing. Jeff's coverage is always complete and very thorough (and he has published quite a number of classic cluster articles on Cluster Monkey). As 2021 progresses, expect more exciting advances from Limulus Computing.

Oct 6, 2020: Limulus V2 now has additional 3.5 inch drive bays. This change allows more spinning hard disk (HDD) storage for both NFS and HDFS (Hadoop Distributed Filesystem). The new Hadoop/Spark Data Analytics cluster (Model 452) supports up to 112 TBytes of raw HDFS storage using enterprise-level HDD drives .

May 29, 2020: One feature that was not mentioned in the previous announcement is the availability of 25 Gigabit Ethernet (25 GbE). The new 25 GbE option is available on base models 102, 202, 302, and 402 and comes standard on models 1202 and 1302.The price to upgrade is the same as the previous 10 GbE option. Benchmarks are forthcoming .

May 7, 2020: Limulus version 2 is here! This new series of machines delivers new features, lower prices, and more performance. The big news are the new micro ATX blades. All Limulus systems (desk-side and rack-mount) can now support almost any micro ATX based motherboard and processor (less than 80W TDP). In terms of processors, all systems now come with AMD Ryzen CPUs. This change brings two new features.

1. True next generation performance with more cores (up to 8 per processor), fast clocks (up to 3.6 GHz), and threads.
2. ECC memory (fully qualified with the Linux Kernel) is now standard on all systems

In terms of storage, we have increased our RAID storage options in both size (up to 54 TB of RAID6 on basic systems) and capability (systems now have six removable HDD bays). In terms of cost, all version 2 Limulus systems (with exception of a slight increase for the Hadoop model 1302) have a lower price AND more capabilities! Take a look at the new high-performance low-cost Limulus lineup.

Finally, we can optimize any system by component or geometry (with 3D printing). If you need specific hardware (i.e. Intel processors) please contact us directly.
