Sun X7056A

The X7056A is Memory Kit manufactured by Sun Microsystems. We gathered information from several on-line sources and complied it here. We hope you find it helpful. If you have any more useful information about this product, please let us know so we can add it to this site.

Compatibilities:

All Sun Microsystems parts are known by at least two numbers, the X-Option number and the Part number. The best way to find out what part you have is the BarCode. Every part that Sun Microsystems sells has a Sun bar-code. This bar-code has both the part number and serial number of the part. (The X-Option number is not located on the part.) Here is a sample Sun Barcode:

An X-Option may have multiple part numbers and a part number may have multiple X-Option numbers associated with it.

Netra 20 Notes:

1. The minimum requirement is four DIMMs of equal size in any group.
2. DIMMs can be installed in any group order.
3. Each group addresses 4GB of memory.
4. The DIMMs in Group 0 do not need to be the same size as those in Group 1.
5. 501-6173 is not qualified for Netra 20.
6. The 501-6174/6109 are 13mm taller than other listed DIMMs.
7. The 501-6109/6174/6109 are not qualified in the Netra 20 750/900MHz configurations.
8. 1GB DIMM FRU F540-5086, which includes 501-6109, was released in October 2001.
9. 1GB DIMM FRU F501-6109 replaced F540-5086 in December 2003.
10. Memory slots (J xxxx ) map to same-numbered DIMMs (U xxxx ):
    
    

    SLOT	DIMM
    J0407	U0407
    J0406	U0406
    J0305	U0305
    J0304	U0304

CPU to Memory Association

CPU to Memory Group Map

Sun Fire V480 & V880 Notes:

1. Four DIMMs of the same size form a group.
2. For 750MHz and 900MHz system boards, the minimum memory is eight DIMMS in groups A0 and B0.
3. For 1050MHz and higher system boards, the minimum memory is sixteen DIMMs in groups A0, A1, B0, and B1.
4. DIMMs must be added four-at-a-time within the same group of DIMM slots; every fourth slot belongs to the same DIMM group.
5. DIMM groups associated with a failed CPU are unavailable for use.
6. Interleaving is limited to memory on the same CPU/Memory Board.
7. Two-way interleaving occurs in any group when the DIMM size does not match the size used in any other group.
8. Four-way interleaving occurs between any two groups when the DIMM sizes are the same.
9. Eight-way interleaving occurs when the DIMMs in all four groups are the same size.
10. 1GB DIMM FRU F540-5086, which includes 501-6109, was released in October 2001.
11. 1GB DIMM FRU F501-6109 replaced F540-5086 in December 2003.

Notes:

1. Four DIMMs of the same size form a bank.
2. A populated DIMM bank requires an UltraSPARC III CPU.
3. 1GB DIMM FRU F540-5086, which includes 501-6109, was released in October 2001.
4. 1GB DIMM FRU F501-6109 replaced F540-5086 in December 2003.

Sun Fire 3800-6800 Notes:

1. For Sun Fire 3800-6800, 1GB DIMMs 501-6109 and 540-5086 are only supported on 900MHz and faster system boards.
