Transcend has announced the release of professional-grade 2GB DDR2-667 VLP (very low profile) ECC registered memory modules.
At less than 3/4 of an inch high, these modules are 40% shorter than standard memory, making them appropriate for use in 1U (or thinner) blade servers and embedded systems with space restrictions, according to Transcend. Due to the low profile design, the VLP DIMM can be installed in vertical memory slots rather than the traditional 45-degree angle server memory slots. Vertical orientation helps maximize usable space in the chassis, improve airflow and heat dissipation, and allows for the installation of more memory modules, noted Transcend.
The 2GB VLP DIMMs are made of 18 Micron 256M×4 DDR2 FBGA (fine-pitch ball grid array) chips. As opposed to traditional server memory with standard ECC, Transcend's 2GB DDR2-667 VLP registered modules incorporate IBM's advanced new Chipkill technology, according to Transcend. With Chipkill, DIMMs are able to check and correct multi-bit errors from a single memory chip, whereas standard ECC is only able to correct one-bit errors. This can significantly increase data reliability, which is especially important for heavy-duty server applications running complex tasks, noted Transcend.
The memory module is available now at a recommended retail price of US$399 before tax, according to the company.
