One can purchase DDR 1066 Mhz memory kits from a variety of different retailers. One can find DDR 106 Mhz memory online at Amazon, eBay, and Crucial.
Those numbers refer to DDR-3 RAM memory, specifically, to its CAS Latency. CAS Latency essentially refers to the speed at which the RAM will be accessed to acquire information. Each number refers to the number of MTs (megatransfers per second) the RAM can deliver as opposed to a processor, which is cycles per second. A DDR-3 1066 will operate at a command rate of 533 MHz and a cycle time of 1.875 nanoseconds. A DDR-3 1333 will operate at a command rate of 666 MHz and a cycle time of 1.5 nanoseconds. Currently the fastest on the market I've seen is DDR-3 1600, at 800 MHz and cycle time of 1.25 nanoseconds.
he rating for RIMM memory is based on the maximum theoretical bandwidth (in MHz) and included speed ratings of 800 MHz, 1066 MHz, 1200 MHz, 1333 MHz, and 1600 MHz.
1600, 1333, 1066, or 800 MHz
There is about 1.04 GHz in 1066 MHz.
no you can not use 400 MHZ ram because (PC2100 @ 266 MHZ ddr) and (PC2700 @ 333 MHZ ddr) are the only chips that are inter changable. PC3200 is 400 MHZ but it has 2 slots not just the one. It does not fit into the same type slot as either PC2700 or PC2100. I was looking at the possibility of a PC2700 ram rated at 400 MHZ but I do not think there is such a thing.
As of 2013, the DDR3 Sdram, 2 GB, Dimm 240-Pin, 1333 Mhz, Ecc is the fastest being sold today. However, when it comes to computer components, the fastest DDR3 DIMM today may not be the fastest next week.
333 Mhz
CPU operates from 166 MHz to more than 3 GHz system can operate from 133 MHz to 400 MHz. CPU is faster than the system bus
1066 MHz, 800 MHz, 533 MHz, and 400 MHz
No they now have CPU in the GHz rannge and RAM 1000+ MHz
A system bus frequency is 1600 MHz. A CPU frequency is 166 MHz to almost 4GHz.
