Always verify against your server's QVL (Qualified Vendor List) before purchasing.
256GB DDR5 modules provide 256GB per DIMM slot. A dual-socket server with 16 DIMM slots can support 4096GB total at full population. Consider your workload's memory requirements and future growth.
Mixing DIMM sizes within the same channel is generally not recommended. For optimal performance, use identical modules across all populated slots. Some server platforms support mixed sizes but with reduced performance.
All three are tier-1 DRAM manufacturers. Performance differences are negligible at the same speed rating. Choose based on price, availability, and your server's QVL (Qualified Vendor List). Samsung and SK Hynix are the most commonly specified in enterprise QVLs.
