System and Memory Configuration Overview
SYSTEM AND MEMORY OVERVIEW
The Sun Fire X4150 and Sun Fire X4250 have 16 DIMM slots for up to 64 GB (16 x 4GB) of PC2-5300 667 MHz ECC fully buffered DDR2 memory.
• 2 FB-DIMMs (minimum configuration) and 16 FB-DIMMs (fully populated configuration)
Caution: Refer to your system owner’s manual for detailed
instructions. System parts are sensitive to electrostatic
discharge and can be damaged by the static charge
you may carry. You should wear a grounded wrist strap.
• The DIMMs must be populated in pairs and the pairs must be identical in organization, size and speed.
• Install the highest-capacity DIMMs in the lowest-numbered DIMM slots.
The Sun Netra X4250 has 16 slots for up to 64 GB (16 x 4GB) of PC2-5300 667 MHz ECC fully buffered DDR2 memory.
• 2 FB-DIMMs (minimum configuration) and 16 FB-DIMMs (fully populated configuration)
• The DIMMs must be populated in pairs and the pairs must be identical in organization, size and speed.
• Install the highest-capacity DIMMs in the lowest-numbered DIMM slots.
Note: When 8GB DIMMs are available, this system will support 128 GB (16 x 8GB)
The Sun Netra X4450 has 32 slots for up to 128 GB (32 x 4GB) of PC2-5300 667 MHz ECC fully buffered DDR2 memory.
• 2 FB-DIMMs (minimum configuration) and 16 FB-DIMMs (fully populated configuration)
• The DIMMs must be populated in pairs and the pairs must be identical in organization, size and speed.
• Install the highest-capacity DIMMs in the lowest-numbered DIMM slots.
Note: When 8GB DIMMs are available, this system will support 256 GB (32 x 8GB)
The Sun Fire X4450 has 32 DIMM slots for up to 256 GB (32 x 8GB) of PC2-5300 667 MHz ECC fully buffered DDR2 memory.
• 2 FB-DIMMs (minimum configuration) and 32 FB-DIMMs (fully populated configuration)
• The DIMMs must be populated in pairs and the pairs must be identical in organization, size, voltage, and speed.
• Install the highest-capacity DIMMs in the lowest-numbered DIMM slots.
Note: Either 1.8V FB-DIMMs (X6382A, DRSX4450/8GB) or low voltage (LV) 1.5V FB-DIMMs (X6437A, DRSX4450LV/16GB) are supported. All FB-
DIMMs must be the same voltage. If you upgrade to LV 1.5V FB-DIMMs, you must replace all FB-DIMMs.
In all systems, the four memory channels are organized into two branches. Modules of identical size must be populated in pairs, starting with memory
slot 0 on each channel (slot 0 on each channel is marked with white handles). DIMMS should be installed with the largest module pair size first. For
example, (4) 4GB DIMMS and (4) 2GB DIMMS should be installed as follows: A0/B0=4G, C0/D0=4G, A1/B1=2G, C1/D1=2G.
