SK Hynix 16GB DDR4-2133 ECC registered DIMM, PC4-2133, for Intel Xeon E5 v3 and v4 rack and tower servers.
This is a refurbished SK Hynix 16GB DDR4 registered ECC memory module, our SKU RAM-SKHYNIX-16G-2133, rated at 2133MT/s to the PC4-2133 standard, also labelled PC4-17000. It is a 288-pin RDIMM running at the standard DDR4 1.2V. Memory of this class arrived with Intel's Xeon E5 v3 processors and remains the standard fitment for Dell PowerEdge 13th generation and HPE ProLiant Gen9 servers, which are still widely deployed. IT teams in Doha and across Qatar use it to add capacity to virtualisation hosts, to bring a partly populated server up to a balanced configuration across its memory channels, or to replace a failed 16GB DIMM like for like. Keeping identical modules on the shelf as spares is also common for estates running Xeon E5 hardware.
RAM-SKHYNIX-16G-2133Will it fit my system?
Registered DDR4-2133 is the standard memory type for Xeon E5-2600 v3 and v4 servers. The models below take this module type.
| Server | Generation | Note |
|---|---|---|
| PowerEdge R630 | Dell 13th generation | 1U, dual socket, DDR4 RDIMM |
| PowerEdge R730 | Dell 13th generation | 2U, dual socket, DDR4 RDIMM |
| PowerEdge R730xd | Dell 13th generation | 2U storage, dual socket, DDR4 RDIMM |
| ProLiant DL360 Gen9 | HPE Gen9 | 1U, dual socket, DDR4 RDIMM |
| ProLiant DL380 Gen9 | HPE Gen9 | 2U, dual socket, DDR4 RDIMM |
Do not mix RDIMMs with LRDIMMs in the same server. Mixing with DDR4-2400 RDIMMs works on platforms that support both speeds, but every module then runs at 2133MT/s. Servers built on Xeon E5 v1 or v2 processors use 240-pin DDR3, which has a different key notch, so this module will not fit them.
Specification
The module runs at 2133MT/s at 1.2V. On Xeon E5 v4 systems that support faster memory it still runs at 2133MT/s, and the memory controller runs every installed DIMM at the speed of the slowest module present.
Installation
Fit memory with the server shut down and the power cords removed, and use antistatic precautions before handling the module. Xeon E5 v3 and v4 processors have four memory channels each, so populate modules evenly across channels following the slot order printed inside the server cover. In a dual-socket server, eight identical 16GB modules, one per channel, give 128GB with full channel bandwidth. Match capacity, speed and module type within each channel. Corrected ECC errors are logged by the server's management controller, which gives early warning of a module that may need replacing.

Ask on WhatsApp sales@serverdove.comIs this SK Hynix 16GB DDR4-2133 module registered or unbuffered?
It is a registered DIMM (RDIMM) with ECC. A register on the module buffers command and address signals between the memory controller and the DRAM. This is what servers need when many DIMMs share a channel. It will not work in desktop motherboards that accept only unbuffered non-ECC DDR4. Check that your system supports registered ECC memory before ordering.
Which servers use 16GB DDR4-2133 ECC RDIMMs?
This memory type is standard in Intel Xeon E5-2600 v3 and v4 servers. That includes Dell PowerEdge 13th generation models such as the R630, R730 and R730xd, and HPE ProLiant Gen9 systems such as the DL360 Gen9 and DL380 Gen9. Many workstations built on the same Xeon platforms also use DDR4 RDIMMs. Always confirm against your system's memory configuration guide.
Can I mix this DDR4-2133 module with faster DDR4-2400 RDIMMs?
Generally yes, provided all modules are registered DDR4 and the platform supports both speeds. The memory controller runs every installed DIMM at the speed of the slowest module, so a mixed configuration operates at 2133MT/s. For predictable behaviour, matching capacity, speed and rank across each channel is good practice. Do not mix RDIMMs with LRDIMMs in the same server.
What does PC4-2133 mean, and is it the same as PC4-17000?
PC4-2133 describes a DDR4 module rated at 2133 megatransfers per second. PC4-17000 describes the same module by its peak bandwidth of about 17,000MB/s, which is the transfer rate multiplied by the 8-byte module width. Both labels refer to the same speed class, so either may appear on listings and system documentation.
Will this memory fit a DDR3 server?
No. DDR4 modules have 288 pins and a differently positioned key notch from 240-pin DDR3 DIMMs, so they physically cannot be installed in DDR3 slots. DDR4 also runs at 1.2V rather than the 1.5V or 1.35V used by DDR3. Servers based on Xeon E5 v1 or v2 processors use DDR3 and need different memory.
What are the benefits of ECC memory in a server?
ECC (Error-Correcting Code) memory stores additional check bits alongside the data. This lets the system detect and correct single-bit errors automatically and detect multi-bit errors. In servers running continuously, it helps prevent silent data corruption, application crashes and unexpected reboots. Server management tools can also log corrected errors, giving early warning of a module that may need replacing.
How should I install these modules for the best performance?
Populate memory evenly across all channels of each processor, following the slot order in your server's documentation. Xeon E5 v3 and v4 processors have four memory channels each. In a dual-socket system, installing eight identical 16GB modules, one per channel, gives 128GB with full channel bandwidth. Uneven configurations still work but may reduce memory throughput.
What does refurbished mean at ServerDove?
Off-lease or decommissioned enterprise hardware that we clean, test and reset in Doha. Every unit goes through POST, burn-in, memory and drive checks and a power-supply check, with firmware and BIOS returned to defaults and drives securely erased.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
