Platform figures are the ones published on the DL360 Gen9 product page; channel arithmetic is JEDEC standard for the processor generation. Confirm against your board revision and BIOS before a large purchase.
Capacity: what fits with each module size
| Module size | 1 module per channel (8 modules) | Full population (24 modules) |
|---|---|---|
| 16GB modules | 128GB | 384GB |
| 32GB modules | 256GB | 768GB |
| 64GB modules | 512GB | 1.5TB |
| 128GB modules | 1TB | 3TB |
Fill every channel before adding a second module to any channel: a balanced population is what gives the platform its full bandwidth. The platform ceiling of 1.5TB is reached with the largest modules the board accepts - the table above shows the practical ceiling for each module size.
How we would populate it
- 1Start with 8 modules - one per channel - using the module size that lands closest to the capacity you need. This is the cheapest route to full memory bandwidth.
- 2If you need more capacity later, add a matched module to every channel (3 DIMM per channel) rather than filling only the free slots on one side: an unbalanced population loses bandwidth and can step the speed down.
- 3Match the module organisation and rank across the population. 2Rx4, 2Rx8 and 4Rx4 parts are not interchangeable on every board, and LRDIMM cannot share a channel with RDIMM.
- 4Buy at the speed the platform runs (up to 2400 MT/s). A faster module runs at the platform ceiling; a slower one pins the channel to its own speed.

Frequently asked questions
How much memory can the DL360 Gen9 take?
The platform has 24 DIMM slots across 8 channels (3 DIMM per channel at full population), and is rated up to 1.5TB. That ceiling needs the largest modules the platform accepts; with smaller modules the practical ceiling is slots × module size, which is the capacity table above.
How many DIMMs per channel does the DL360 Gen9 support?
8 channels and 24 slots gives 3 DIMM per channel. Population matters: filling every channel with one module (8 modules) is the balanced starting point, and going to 3 DIMM per channel is what reaches the full slot count. Some platforms step the memory speed down at the higher population - confirm the population rules for your exact board.
What memory type and speed should I buy for the DL360 Gen9?
DDR4 RDIMM or LRDIMM at up to 2400 MT/s. The CPU generation on the platform (Xeon E5-2600 v3/v4 (Haswell/Broadwell)) sets the ceiling; a faster module runs at the platform speed, and a slower module pins the channel to its own speed. LRDIMM is only needed where you want the highest capacity per module and the platform supports it.
Can I mix module sizes in the DL360 Gen9?
Usually yes at JEDEC speed, provided the organisation and rank are close enough for the platform to train, but a mixed population runs at the speed of the slowest module and can lose the balanced interleaving. For a new build, populate all channels with identical modules; mixing is for upgrades where the existing population is already fixed.
Do you supply memory tested for the DL360 Gen9, and how is it shipped?
Yes - modules are checked against your order (part number, capacity, organisation and speed read from the label) and shipped from the Hong Kong warehouse with full export documentation, typically 3-7 days by air. Condition - new or decommissioned pull - is stated line by line before you order, and every module carries a 1-year written warranty.
