DIMM pairs must be matched in size, speed, and technology. The following DIMM pair is mismatched: DIMM x and DIMM y.

Faulty or improperly installed memory modules.

Mismatched or unmatched DIMMs installed; faulty or improperly seated memory module(s).

See "Troubleshooting System Memory" on page 110.

Ensure that all pairs of memory modules are of the same type and size and that they are properly installed. See "Memory" on page 80. If the problem persists, see "Troubleshooting System Memory" on page 110.

Mismatched or unmatched DIMMs installed; faulty or improperly seated memory module(s). The system will operate in a degraded mode with reduced ECC protection. Only memory installed in channel 0 will be accessible.

Ensure that all pairs of memory modules are of the same type and size and that they are properly installed. See "Memory" on page 80. If the problem persists, see "Troubleshooting System Memory" on page 110.

Dual-rank DIMM paired with Single-rank DIMM - The following DIMM/rank has been disabled by BIOS: DIMM x Rank y

Mismatched DIMMs installed; faulty memory module(s). The system has detected a dual-rank DIMM paired with a single-rank DIMM. The second rank of the dual-rank DIMM will be disabled.

Ensure that all pairs of memory modules are of the same type and size and that they are properly installed. See "Memory" on page 80. If the problem persists, see "Troubleshooting System Memory" on page 110.
