Memory Price Spikes

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.

Spring 2026 Memory Update

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.

Ryzen Zen 5 Systems

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.

Ryzen 5700x3D and lower prices (2)

Jan 17, 2023: Limulus models 212 and 1212 now ship standard with Ryzen 9 5800X3D (8-cores @ 3.4GHz and a whopping 96MB of L3 cache) with no price increase. These processors are perfect for HPC workloads! These systems can also be ordered with twelve-core Ryzen 9 5900x and sixteen-core Ryzen 9 5950x if you need more cores and less memory bandwidth. Model 112 with four six-core Ryzen 5 5600X processors has been reduced 7% along with some other upgrades.

Ryzen Zen 4 Systems

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.

128 Cores/256 Threads Next to Your Desk!

Mar 10, 2022: Do you need fast x86_64 cores? Certain Limulus models now support the twelve core Ryzen 9 5900x and sixteen core Ryzen 9 5950x! This change brings the total number of physical cores to 64 for model 212 (128 threads) and an astounding 128 physical cores on model 1212 (256 threads). These processors are specified ro run at 105 Watts TDP and do not fit into the Limulus power/heat envelope. However, they have been configured for ~65 Watts TDP using a lower power threshold (essentially slightly down clocking the max frequency). Our tests indicate a maximum performance decrease of only 6%. In many cases the decrease is much less. Add our internal 25 GbE Ethernet option to these systems and create a massive parallel cluster next to your desk within the classic Limulus low noise, heat, and power envelope. This capability is offered on select AMD Ryzen 5000 (Zen-3 ) Limulus HPC systems (Hadoop systems coming soon). Contact us with your questions and configuration needs.

New AMD Zen-3 Systems Are Ready

Nov 9, 2021: We are happy to announce the availability of our AMD Ryzen 5000 (Zen-3 ) Limulus HPC systems (Hadoop systems coming soon). Like the previous Zen-2 (Ryzen 3000) systems, models are available with 24, 32, and 64 cores and use ECC memory. The new Ryzen 5000 systems now offer faster Zen-3 cores, DDR4-3200 ECC memory, and NVMe over PCI-4 for improved main node storage throughput. The lower priced Ryzen 3000 (Xen-2) systems will still be available for a limited time.

Limulus Highlighed for Desktop Supercomputing

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.

New Model 452

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 .

25 GbE Option Now Available

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 .

Limulus Version 2 is Here!

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.

Blade Pictures

Nov 17, 2019: Below are some pictures of the new low-cost Limulus V2.0 blades. These images below are prototypes, we will be posting updated images after SC19 in Denver. If you are attending the show, you can see the blades and how they fit into the LImulus case at Booth 996 (under Gidel on show map, look for Limulus Computing). We will also be showing our new Ryzen (Zen 2) nodes with ECC memory, headless booting, and lots of cores. We have also included some i7 nodes to show the "mix and match" capability of the new blades. Click for larger images. There is also a new master data sheet for all systems.

The uATX Blades are Coming

Oct 30, 2019: Limulus 2.0 will be officially announced at SC19 in Denver. This evolutionary design will offer uATX blades for Limulus systems (desk-side and rack-mount). This feature allows easy (hot swap) removal and the ability to mix and match blades. The following CAD images provide a small preview of the new systems. The image on the right is the "front" where blades (gold ) are vertically loaded into a desk-side case. The blue parts are the blade support guides that fit into our desk-side case. The view on the right shows the "side" of the blades with the hot-swap connectors (the three blue boxes on the upper right side). Check back as SC19 approaches for more information on the new Limulus 2.0 Edge systems. (Click on images for larger view.)

Ryzen on the Horrizon!

Oct 16, 2019: If you are interested in more cores/threads (64 c/t per system) and ECC memory, Contact Basement Supercomputing and ask about our new low cost Ryzen based systems. We will be shipping at the end of the month.

Limulus vs The Cloud

August 22, 2019: A new white paper comparing a Limulus to Amazon EC2 instances. In this careful study equivalent EC2 cluster instances were configured using current pricing (Spring 2019). The results were quite interesting. From the Executive Summary:

  • The Limulus appliance meets or exceeds the capabilities of a similar cluster configured using EC2 instances.
  • The one-year lease cost for a comparably configured EC2 cluster equals or exceeds the purchase price of a Limulus cluster
    • appliance.
  • If the cost of renting EC2 instances for one year is applied to purchasing a Limulus appliance, the resource will provide at least 2-3 years of service.
  • Software configuration and support costs are not part of the cloud instance cost. Limulus appliances are turn-key and require minimal administration effort.
The full paper is available from Cluster Monkey (reg required). If you don't want to register on Cluster Monkey, you can Contact Limulus Computing directly and we gladly will send you a copy.

Xeon E Series and Rack-Mount Options

February 4, 2019: Two new product developments! First, we now offer upgrades to Intel Xeon E-2176G and E-2146 processors.These processors ae based on the Intel six core (plus 6 threads) Coffee Lake architecture and run at 3.7 and 3.5 GHz respectively. (They will also burst to 4.7 and 4.5 GHz for single threads!) In addition, they provide an ECC memory option to all Limulus systems.

Second, we now have a rack-mount case! The same turn-key convenience found in all desk-side Limulus systems is now available in a rack mount chassis. We offer a small rack cabinet that will house four of these systems (96 total physical cores) in an office/lab environment (that means low noise, low heat, and low power). There is no data center needed. And, if you want to place them in a data center these units can used in standard 19 inch cabinets. Check out the Limulus models and options. If there is something you don't see or have any questions simply contact Basement Supercomputing.

New Redundant Power Supply Option

July 11, 2018: Over the years there have been occasional requests for redundant power supplies for Limulus systems. We also note that there has never been a power supply issue with any Limulus system. We attribute this reliability to proper design and high quality components. While we stand by this record, we are pleased to offer a reasonably priced redundant power supply option on all standard Limulus models (100-400). A similar option is in the works for the larger Limulus systems (Models 1200 and 1300). Finally, a little hint of things to come. What other types of systems like to use redundant power supplies (and sit in a rack chassis)? Stay tuned because the easiest turn-key HPC, Hadoop, and Deep Learning appliance solutions are about to come in another packaging option.

New 6-core Coffee Lake Systems

December 1, 2017: The entire Limulus product line now has more cores! The new Intel Coffee Lake processors provide 6-cores of processing power. This update means all Limulus HPC and Hadoop systems have at least 24 cores! The large systems have 48 cores (plus and equal number of threads)! The prices are about the same as our previous Kaby Lake (4-core) systems (most price increases are do to the cost of memory). To accommodate more cores, the clock speeds are a bit lower, but processor caches are bigger and the DDR4 memory is now running at 2666 MHz. Check out all the system details on the products page. Two things to note about the updates. First, the Xeon ECC options still use 4-core processors, we are waiting on Intel for updates. Second, the availability of Coffee Lake i5 and i7 processors has been quite poor (due to Intel marketing games). This situation is expected to get better in the first quarter of 2018. We will ship systems as the processors become available (we have Coffee lake processors in house for testing and are delivering our first Coffee Lake systems this month). Order now to get one of the these new systems in the new year!

Hadoop Systems Upgrades

June 24, 2016: All Limulus Hadoop system worker nodes now include an M.2 (on-board SSD) drive to hold the OS and Hadoop software. This change allows the larger removable SSD drives to be used exclusively for HDFS. In addition, the main (login) node on the Model 300 has been augmented with an i7-6700 processor and 32GB of memory. This change provides more horsepower for many of the Hadoop packages. All Limulus models can be found on the product page.
