Compared to other nowadays standards the Rambus shows significantly increasing latencies, heat output and manufacturing complexity. The combination of high manufacturing costs as well as high licence fees make these advantages appear useless. The Rambus had been intended to replace the SDR RAM. Higher pulsing, access times and error-free processing should ensure its victory. The problem with the Rambus had been and still is its price. The licences compared to the DDR RAM which are much too high brought it a side role as Intel also officially distanced itself from Rambus. The advantage of the higher pulsing does not play a role any longer as the consequent enhancement of the DDR RAM memory module undid this advantage. One of the advantages of the RD RAM memory module had been the synchronous pulsing by the FSB of the Intel CPUs. The Rambus with the pulse frequency of 400 MHz (PC800) or 533 MHz (PC1066) possesses more than 168 pins and requires a tension of 2.5 volts. The only difference is being found in the 16 bit module and the 32 bit module.
