Memory configurator
Tell us the platform and how much memory you want per node. We work out the valid populations from what is on our shelf, and show where the cheaper option costs you speed, which is the part people get wrong.
6 channels per socket, 2 slots per channel — 24 slots in this node.
2933 needs one DIMM per channel. Fill the second slot in a channel and the whole bus drops to 2666 — on 1st-gen (Skylake) CPUs the ceiling is 2666 either way.

- Rated 2933 but will run at 2666 here — 2 DIMMs per channel caps the bus at 2666.
- 8 modules per socket does not divide evenly across 6 channels. It will boot, but you lose memory bandwidth and the management controller will flag the population as unbalanced.
- We hold 0 — 16 short of this build. We can source the balance; ask for a lead time.

- Gives 1.5TB, which is 512GB more than the 1TB you asked for — this platform has 6 channels per socket, so the population has to land on a multiple of that to stay balanced.
- Rated 2933 but will run at 2666 here — 2 DIMMs per channel caps the bus at 2666.
- We hold 0 — 24 short of this build. We can source the balance; ask for a lead time.
- Fills every slot, so there is no headroom to add memory later without replacing modules.

Before you order on the back of this
These are indicative rules from published OEM population guidelines. Slot counts and speed derates vary by CPU model and BIOS level, so check the QuickSpecs or Owner's Manual for your exact machine — or send us the model and serial and we will confirm it in writing before you commit. We would rather answer a question than take a return.
