Legacy 4GB Fully Buffered DIMM Announced


Electronics Eliminates Need for Dual Die Devices, Offers Cost Savings

PC design engineers and system integrators now have a new, immediately available option for a fully buffered dual in-line memory module (FB-DIMM) that offers high density in a standard form factor. The 4GB DDR2 FB-DIMM from Legacy Electronics is a JEDEC-standard, pin-out DIMM offering a low-profile (1.18 inch or 30mm) PCB height in speeds ranging from PC2-3200 to PC2-5300. This means that Apple- and Intel-platform designers, and more specifically any high-speed, high-density blade server and 1U-Chassis designers, can address their applications’ needs without stacking or use of dual die devices. This new DIMM option translates to a significant cost savings and increased performance in most designs.

Jason Engle, president of Legacy Electronics, added, “We believe Legacy is first to market with a qualified 4GB FB-DIMM for both the Apple and Intel platforms. Our design meets the height restrictions necessary for a 1U server chassis, and the popular MacPro.”

Legacy’s new 4GB FB-DIMM also provides the reliability of Advanced Memory Buffer (AMB), which replaces registers and phase lock loops (PLLs) used on other DIMMs. The AMB buffers the DRAM devices from the channel, and uses a high-speed, point-to-point differential interface to communicate with the controller. This process translates to increased system memory capacity, reduced memory channel pin count, and higher reliability.

Availability and More Information
The 4GB DDR2 FB-DIMM is available now in 100-unit quantities at $895. More information is available by contacting Legacy Electronics. For details on worldwide sales representatives and distributor locations, go to, call 949-498-9600, or toll-free at 888-466-3853.
