1TB DDR4-3200 ECC RDIMM kit for QNAP TS-h2490FU
This kit provides 1TB of DDR4 3200 PC4-25600 CL22 ECC Registered memory in four 256GB modules. It is designed for the QNAP TS-h2490FU server platform where ECC Registered DIMMs are required. Standard desktop computers cannot use this memory type and it must not be mixed with unbuffered or load-reduced DIMMs.
DDR4-3200 Registered ECC limits
The modules operate at 3200 MT/s with CL22 latency and 1.2V voltage using 8Rx4 octal-rank organisation. Registered ECC adds a register clock cycle that reduces electrical load on the memory controller, allowing higher capacities per channel. Mixing with unbuffered or load-reduced memory is not supported and will prevent the system from booting.
Four-module installation in TS-h2490FU
Install all four 288-pin RDIMMs in the matching slots of the TS-h2490FU following the motherboard population order. Ensure each module clicks fully into place; incomplete seating is the most common cause of boot failure or memory errors. Do not combine these Registered DIMMs with any unbuffered or load-reduced modules already present in the system.

أسئلة حول هذا المنتج
Should I pick the 4×256 GB kit or a different capacity for the TS-h2490FU?
The kit provides four 256 GB DDR4 3200 CL22 ECC registered RDIMMs for a total of 1 TB, matching the TS-h2490FU's supported configuration.
What does the 3200 MT/s rating deliver inside the TS-h2490FU?
The modules run at DDR4 3200 (PC4-25600) with CL22 latency, giving the TS-h2490FU its maximum supported memory bandwidth for multi-threaded workloads.
Is the 288-pin DDR4 interface the limiting factor for speed in this server?
Yes, the 288-pin DDR4 ECC registered RDIMM interface caps transfer rates at the JEDEC 3200 MT/s specification used by the TS-h2490FU.
