EVGA Classified SR-2 Motherboard

Installing DIMMs

Your new motherboard has twelve (12) 240-pin slots for DDR3 DIMMs

(ECC or Non ECC). They are arranged in two (2) sets of Six (6) slots each.

These slots support 1Gb, 2Gb, and 4Gb DDR3 technology. There must be

at least one DIMM slot populated in each bank to ensure normal operation.

Use the following recommendations for installing DIMMs. (See Figure 1 on

page16 for the location of the DIMM slots.)

 One DIMM: If using 1 DIMM (Single Channel), install into: DIMM slot

 Two or Four DIMMs: If using 2 DIMMs (Dual Channel), install into:

DIMM slots 1 and 3. If using 4 DIMMs (Dual Channel), install into:

DIMM slots 2, 1, 4, and 3.

 Three DIMMs: If using 3 DIMMs (Triple Channel), install into: DIMM

slots 1, 3 and 5.

 Six DIMMs: If using more than 4 DIMMs, use: DIMM slots 2, 1, 4, and

3 then proceed to occupy the following DIMM slots in this order: 6 and 5.

Use the following procedure to install DIMMs. Note that there is only one

gap near the center of the DIMM slot. This slot matches the slot on the

DIMM to ensure the component is installed properly.

1. Unlock a DIMM slot by pressing the module clips outward.

2. Align the memory module to the DIMM slot, and insert the module

vertically into the DIMM slot. The plastic clips at both sides of the

DIMM slot automatically lock the DIMM into the connector.
