== Upgrade to Server-Grade Parts == In 2004, Virginia Tech upgraded its computer to Apple's newly released, [[Xserve]] G5 servers. The upgraded version ranked #7 in the 2004 [[TOP500]] list and its server-grade [[Dynamic random access memory#Errors and error correction|error-correcting memory]] solved the problem of cosmic ray interference. In October 2004, Virginia Tech partially rebuilt System X at a cost of about $600,000. These improvements brought the computer's speed up to 12.25 Teraflops, which placed System X #14 on the 2005 [[TOP500]] list.
