Buy used DDR4 server RAM and save costs
Powerful, efficient, cost-effective: although DDR5 RAM is now considered the latest memory technology for servers, servers with DDR4 memory remain a preferred and, above all, the right solution. Because - contrary to what you might think - the latest technologies are not always the best or most sensible options. DDR5 RAM modules are still a rarity on the second-hand market - in other words, in most cases companies have to resort to new products, which are usually very expensive. For SMEs or start-ups, the latest technologies are often not feasible - and even more often not necessary. This is because the potential that many DDR4 servers have is largely not utilised - a switch to even higher-performance hardware is therefore not necessary, especially if the existing IT infrastructure has proven itself, is sufficiently protected and is regularly updated.
It makes much more sense to give existing systems a RAM upgrade if required. Whether with 16GB DDR4 modules, 32GB DDR4 modules or 64GB DDR4 modules - depending on the capacity you need, we offer you a cost-effective and sustainable option for your server memory upgrade in our hardware shop. Used DDR4 RAM modules are an economical and clever alternative to new products and still offer stable and reliable performance. Server models that support DDR4 memory modules include the HPE ProLiant DL380 Gen10, DL560 Gen10 and DL360 Gen10. Depending on the sizing, this popular product series from HPE can function as a database, file or web server. You can also find detailed information on server sizing in our blog post: What configuration do I need for my rack server?
DDR4 server memory: variants and advantages
As with its predecessor, DDR3 RAM, most DDR4 memory modules for servers are also equipped with ECC technology. The Error Correction Code detects and minimises memory errors, thereby ensuring stable performance.
And similar to the predecessor modules, there are also different main types into which the DDR4 RAM modules can be categorised. DDR4 UDIMMs (unbuffered DIMM modules) are mainly RAM modules for standard PCs - DDR4 UDIMMs with ECC technology, on the other hand, are particularly suitable for small servers or workstations. They are inexpensive, easy to install - but are predominantly only supported by certain systems. It is worth taking a look at the manufacturer's data sheet to check compatibility. Alternatively, you can also contact us directly if you require support or further product information.
DDR4 RDIMM modules (Registered DIMMs) are used more frequently in servers. Thanks to error correction and register chips, they offer high stability, scalability and reliability in high-performance enterprise servers and data centres, making them an ideal choice for professional environments. The modules can be recognised by the fact that the letter ‘R’ or the abbreviation ‘reg.’ appears in the designation, such as PC4-2400R or DDR4 PC4-2400 REG ECC RAM.
The DDR4 LRDIMMs (Load Reduced DIMMs) go one step further. The load-reduced technology has a built-in buffer memory and therefore reduces the load on the memory controller, which enables a higher memory density. These modules are used in all high-performance servers that are designed for exceptional scalability and high RAM capacities.
In addition to these ‘main types’, the modules can of course also be categorised and differentiated according to capacities, data rates or CAS latencies. Designations such as PC4-17000, PC4-21300 or PC4-25600 indicate the maximum data rate - additions such as PC4-2133, PC4-2400, PC4-2666,PC4-2933 or PC4-3200 indicate the module designation. Depending on the system requirements, modules with capacities of 4GB, 8GB, 16GB, 32GB, 64GB or even 128GB can be selected.
The CAS latency (Column Address Strobe Latency) also indicates how many clock cycles a RAM module requires to respond to a processor request. A lower CAS latency means faster access to the data - higher CAS latencies mean more delay, but often also higher clock rates. It is therefore an important indicator of the performance of the memory.
DDR3 vs. DDR4 RAM: How have RAM modules evolved?
Even if it doesn't always have to be the very latest technology and hardware: Switching from servers with DDR3 to servers with DDR4 RAM can be extremely worthwhile in many cases. This is because DDR4 offers an improved data transfer rate and higher memory capacities compared to DDR3. This means that DDR4 has a higher bandwidth and therefore faster data processing. This is particularly advantageous for data-intensive applications such as virtualisation, cloud computing or database servers.
DDR4 modules operate at just 1.2V instead of 1.5V (DDR3) - this lower voltage means greater energy efficiency, reduced power consumption and, in the best case, lower operating costs. Companies that use a large number of server systems in particular benefit from this. And even though DDR3 modules often have lower CAS latencies, the higher bandwidth compensates for this. Thanks to the high data transfer rates of DDR4, the response times are still faster overall than with DDR3.
If you want to rely on AI systems and modern hardware, you should also switch to systems with DDR4 RAM as a minimum. This is because DDR4 supports higher memory densities and therefore offers improved scalability. The module sizes vary from 8 GB to 128 GB - this means that companies can expand their servers to larger capacities with fewer modules and still remain flexible and quickly boost performance.
Affordable, efficient, sustainable: refurbished DDR4 RAM modules
More flexibility, scalability, performance and reliability with better energy efficiency - this is what DDR4 RAM modules generally offer you. DDR4 also offers higher bandwidth and capacity, allowing companies to better scale their IT infrastructure without having to immediately switch to the latest generation (DDR5). By purchasing used DDR4 RAM modules, you are also making an important contribution to greater sustainability: the longer the hardware remains in use, the less new hardware needs to be produced. Resources are conserved, while the disposal rate is reduced at the same time.
In addition to the lower costs, this is one of the main advantages why companies rely on remanufactured DDR4 RAM modules. Whether you are looking for 8 GB DDR4 modules, 32 GB RAM modules or 64 GB DDR4 RAM modules - we are sure to have the right memory modules in stock. In our server shop for hardware of all kinds, you also benefit from our many years of experience, outstanding quality, our wide and deep range, personal contacts and our lightning-fast dispatch.
