Achieve Cutting-edge Performance Operating at a speed of 533MHz and a bandwidth rate of 4266MB/s, this HP, 256MB PC2-4200U server memory module achieves cutting- edge- performance at an affordable price, signifying an exceptional option for server memory expansion. HP has developed world- class products since 1939 and continues to push the boundaries, continually defining what it means to be a global leader in technological solutions.

DDR2: Realise Your Server’s Full Potential DDR2 brings revolutionary memory technology to your server. Dramatic upgrades to speed and power efficiency have been overseen, ensuring that it is a major step up in performance capabilities compared to DDR. An upgrade in speed is realised through the 50% increase in prefetch length growing from 2 to 4 bits. The power efficiency enhancement can be shown through the reduction of voltage from 2.5v to 1.8v and the consequent fall in total working costs.

Avoid System Crashes ECC (error- correcting code) assists your system in preventing system crashes through the automatic identification and correction of the most common types of data corruptions. An uninterrupted layer of protection for your server, this memory module is registered (buffered). A register can be found among the DRAM modules, this provides your individual modules with boosted stability which then feeds into system constancy.
