❓Frequently Asked Questions
Q1: Can I mix these modules with other Sun memory references in my server?
It is strongly discouraged to mix different references or capacities of memory modules in the same group of DIMM slots. All modules in a group (4 sticks) must be identical in capacity, speed, and type. However, you can use modules from different manufacturers (Samsung, Micron, Infineon) as long as they are all certified 501-7385-01.
Q2: Are all 20 modules from the same chip manufacturer?
No, the lot can contain a mix of modules made by Samsung, Micron, and Infineon. All carry the reference Sun 501-7385-01 and are 100% compatible with each other. Sun Microsystems qualified several manufacturers for this reference, ensuring total interoperability.
Q3: What is the maximum memory capacity I can achieve on my Sun Fire V880?
The Sun Fire V880 supports up to 32 GB of RAM maximum with 1 GB modules. With 512 MB modules like these, you can install up to 16 GB (32 slots x 512 MB). The configuration is done in groups of 4 modules in 8 different DIMM groups spread across the CPU/Memory boards.
Q4: Do these modules work on a Sun Blade 1500 or Sun Blade 2500?
No, the Sun Blade 1500 and 2500 use DDR SDRAM memory, not PC100 SDRAM. These modules 501-7385-01 are exclusively for UltraSPARC III systems using ECC Registered SDRAM, such as the Sun Fire V480/V880 and Sun Blade 1000/2000.
Q5: How can I verify that the modules are recognized after installation?
At startup, press Stop+A to access the OpenBoot PROM (OBP). Type the command "show-devs" or ".properties" to display the devices. You can also use "probe-scsi-all" then "printenv" to see the memory configuration. Once Solaris is started, the command "prtconf | grep Memory" will display the total recognized memory.
Q6: Should the 20 modules be installed all at once?
No, absolutely not. You must install the modules in groups of at least 4 (a complete DIMM group). With 20 modules, you can create 5 complete groups of 4 sticks, totaling 10 GB. You can distribute them across multiple servers as needed: for example, 2 servers with 8 modules each (4 GB), plus a third with 4 modules (2 GB).
Q7: What is the difference between reference 501-5030 and 501-7385?
Both references are 512 MB SDRAM ECC PC100 modules, but they differ slightly in their electrical specifications and compatibility with certain motherboard revisions. The 501-7385 is a newer revision compatible with a wider range of Sun systems, including the V480/V490/V880/V890. Both can coexist in the same system.
Q8: Are the modules compliant with RoHS standards?
RoHS compliance depends on the manufacturing date and the specific manufacturer (Samsung, Micron, or Infineon). Modules produced after 2006 are generally RoHS compliant. For strict RoHS requirements, please contact us before purchase to verify the availability of certified modules.
🔧Technical Installation Notes

Installation precautions:

  • Always completely power off the server and unplug the power supply before handling
  • Use an anti-static wrist strap when installing memory modules
  • Install the modules firmly until the clips click
  • Follow the installation order of the groups: A0 and B0 first, then A1 and B1
  • Check that the modules are properly aligned before applying pressure

Diagnostics in case of problems:

  • Diagnostic LED: check the CPU/Memory LEDs on the board to identify errors
  • Test the modules one by one if the system does not start
  • Ensure that the groups of 4 modules are complete
  • Check the compatibility of the OBP firmware revision with the memory capacity
