While working on a computer you notice RDRAM memory is installed. What are some of the disadvantages of using RDRAM? Choose two.
  1. RDRAM runs much more slowly than SDRAM.
  2. RDRAM modules generate significantly more heat.
  3. RDRAM can only be used in PCs and cannot be adapted for other uses.
  4. RDRAM modules have a memory controller on each module.
Explanation
Answer: B and D - RDRAM chips generate more heat than SDRAM modules and require the use of heat spreaders. The fact that they have a memory controller on each stick increases manufacturing complexity.

Key Takeaway: Direct Rambus DRAM (DRDRAM, also known simply as Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM designed by the Rambus Corporation.
