❓ Frequently Asked Questions
Is this DDR3 ECC PC3-8500E RAM compatible with my HP ProLiant, Dell PowerEdge, or IBM server?
The PC3-8500E ECC Unbuffered UDIMM DDR3-1066 memory is compatible with a wide range of Intel Xeon (Nehalem/Westmere) and AMD Opteron generation servers that accept unregistered ECC RAM. It works notably in HP ProLiant ML/DL G6, Dell PowerEdge T/R410, IBM System x3200/x3400. Always check your motherboard’s Qualified Vendor List (QVL) before installation.
What is the difference between ECC Unbuffered RAM (UDIMM) and ECC Registered RAM (RDIMM)?
The ECC Unbuffered RAM (UDIMM) corrects memory errors but communicates directly with the controller, making it suitable for entry-level workstations and servers. The RDIMM (Registered) includes an additional buffer register for high-density servers. These two types are not interchangeable — make sure your system supports Unbuffered ECC memory before purchasing.
Can I use this 8 GB kit (4x2 GB) in dual channel to improve performance?
Yes! This set of 4 identical modules (same P/N M391B5673DZ1-CF8, same production code 0918, same CL7 timings) is perfect for a dual channel symmetric configuration. Install the 4 DDR3 sticks in the recommended slots on your motherboard (usually alternating slot colors) to double memory bandwidth and optimize your server or workstation’s performance.
Is the Samsung M391B5673DZ1-CF8 RAM tested before shipping?
Absolutely. Each SDRAM DDR3 ECC 2GB Samsung stick in this set has been individually tested and verified functional before shipping. We offer a 30-day warranty on this set: if a defective module is found upon receipt or within 30 days, contact us for a free replacement or refund.
Is this PC3-8500E RAM set compatible with HP Z-Series workstations, Dell Precision, or Lenovo ThinkStation?
Yes, DDR3 ECC Unbuffered 1066MHz 2Rx8 memory is also very common in professional workstations from the Nehalem/Westmere generations, such as HP Z400, Z600, Z800, Dell Precision T3500, T5500, T7500, and Lenovo ThinkStation S20 and D20. Make sure your platform supports ECC Unbuffered memory and check the manufacturer’s documentation before ordering.
Can this 1066MHz PC3-8500E RAM be mixed with other DDR3 modules at 1333MHz or 1600MHz?
Mixing DDR3 modules with different frequencies is technically possible but not recommended: the system will automatically align to the lowest frequency (1066 MHz) and may cause instability depending on the platform. For optimal performance and stability, it is best to use identical modules — which this set of 4 homogeneous Samsung sticks guarantees by default.
