FAQ's
What systems are compatible with the X7801A memory kit? The X7801A is compatible with Sun Microsystems servers that support 240-pin DDR2 registered DIMMs operating at PC2-4200 or PC2-5300 speeds. Verify the server motherboard supports ECC registered memory before installation. What does ECC Registered memory mean? ECC Registered memory includes error-correcting code that detects and corrects common data corruption, and the registered feature buffers the memory for improved signal integrity, often used in servers for stability. Can this module run at both 533 MHz and 667 MHz speeds? Yes, the X7801A modules support DDR2 speeds of 533 MHz and 667 MHz, allowing compatibility with systems operating at either memory speed. How many pins does the X7801A module have? The memory modules in the X7801A kit use a 240-pin RDIMM form factor, which must match the server's DIMM slot configuration for proper installation. Is the X7801A a single or dual module kit? The X7801A is a 2GB kit comprised of two 1GB DDR2 ECC Registered RDIMM modules intended for installation as a matched pair. Does the X7801A support non-ECC or unbuffered systems? No, this kit consists of ECC Registered DIMMs and is designed specifically for systems requiring ECC and registered memory types.
