DDR3 Very High Density DIMMs

Virtium has just introduced its new line of DDR3 Very High Density (VHD) DIMMs in the following form factors: 16GB RDIMMs, 8GB VLP RDIMMs, 4GB VLP mini-RDIMMs and 4GB ECC/nonECC VLP UDIMMs. These new high density memory modules provide significant performance improvements for high-end chipsets, quad core processors and new operating systems such as Microsoft Windows 7, Windows Embedded Server and Windows Embedded Enterprise. The Virtium DDR3 VHD DIMMs are well suited for space-confined applications in embedded systems, military/aerospace computers, telecom networking equipment and storage platforms.

DRAM Memory Error Rates

Google Inc., with the help of University of Toronto Canada, has completed a field study on DRAM memory error rates and produced a research paper on the subject. The Google research shows that faster and denser memory technologies have had no appreciable effect on increasing memory error rates, and while higher temperatures can cause higher memory error rates, the effect is not as high as attributed to the utilization rates on the DIMMs. Temperature is not the biggest cause of stress – swapping data in and out is. The number of soft correctable single bit errors will increase as memory modules age, with error rates spiking up after between 10 and 18 months in the field with DIMM soft correctable error rates on the order of 25,000 to 75,000 failures in time (FIT) per billion hours of operation per Mbit. In contrast, the incidence of uncorrectable hard multi-bit errors will go down over time as failing DIMMs get replaced and the remaining hardy DIMMs stay in the system.
