|---|---|---|---|---|---|
| How does the CPU get data from DRAM? | The CPU sends via the address bus to the MCC the line of code it needs and then the MCC finds the data and sends it back.
🗑
|
||||
| What does the acronym SDRAM stand for? | synchronous dynamic random access memory- meaning it's tied to the system clock
🗑
|
||||
| What stick of RAM is SDRAM? | DIMM- dual inline memory module
🗑
|
||||
| How many pins are on a DIMM? | 168 pins
🗑
|
||||
| How many pins are on a microDIMM? | 68, 144, 172 pins for netbooks
🗑
|
||||
| How many pins are on a SODIMM? | 72, 144, 200 pins laptops
🗑
|
||||
| What speeds did SDRAM run at? | 66, 75, 83, 100, 133 MHz
🗑
|
||||
| What clock speed do you have to select in order for SDRAM to work? | SDRAMs clock speed has to match or exceed the clock speed from the frontside bus.
🗑
|
||||
| A tech installs a new PC83 SDRAM module into a Pentium III computer with a 100 MHz frontside bus. What will happen? | The system will be unstable because the SDRAM speed does not match the speed of the frontside bus.
🗑
|
||||
| Intel's Pentium 4 had a clock speed of 400 MHz. What RAM had to be invented in order for this CPU to work? | RAMBUS DRAM- RDRAM- at a speed of 800 MHz - $$$
🗑
|
||||
| What is the memory stick called for DRAM? | SIMM- single inline memory module
🗑
|
||||
| What is the memory stick called for RDRAM? | RIMM
🗑
|
||||
| Why was DDR SDRAM created? | It was the industries response to RAMBUS and allowed for 2 processes to occur for every clock cycle.
🗑
|
||||
| What does the acronym DDR SDRAM stand for? | Double Data Rate SDRAM.
🗑
|
||||
| What CPU did the DDR SDRAM copliment? | Athlon and AMD processors double- pumped frontside bus
🗑
|
||||
| What is the pin amount for DDR SDRAM? | 184 pin DIMMS
🗑
|
||||
| What is the pin amount for DDR SDRAM SODIMMS? | 200 pin SODIMMS
🗑
|
||||
| What is the pin amount for DDR SDRAM micro DIMMs? | 172 pin MicroDIMMS
🗑
|
||||
| What are 2 naming conventions for DDR SDRAM? | name of sticks- bytes/ second, MHz speed x 8 bytes then add PC- 400MHz x8B= 3200 MBps, or PC3200; or named by individual DDR chips- DDR400- 400 MHz running on a 200 MHz clock.
🗑
|
||||
| What does dual channel architecture mean? | 2 sticks of RAM together. Started with RAMBUS
🗑
|
||||
| What is the advantage to DDR2? | electical characteristics, so it runs faster with less power.
🗑
|
||||
| What allowed the DDR2 to run at faster I/O speeds? | special buffers that act like a cache
🗑
|
||||
| How many pins are on the DDR2 DIMM and SODIMM? | DIMM- 240 and SODIMM- 200
🗑
|
||||
| How many pins are on the DDR3 DIMM and SODIMM? | DIMM- 240 and SODIMM-204 pins
🗑
|
||||
| What 3 features does DDR3 RAM provide? | 1. buffer allows 8 bis bandwidth. 2. XMP- extended memory profile- power users to easily overclock their RAM 3. higher density memory chips- 16 GB modules
🗑
|
||||

🗑
|
||||
| What Intel system supports the triple channel memory? | LGA 1366 platform
🗑
|
||||
| Where would you find the use of the DDR3L/ DDR3U? | Server farms or data centers- low voltage less heat- DDR3L- 1.35 v; DDR3U- 1.25v
🗑
|
||||
| What voltage does DDR3 RAM run at? | 1.5v or 1.65 v
🗑
|
||||
| What are the specs on the DDR4? | 1.2 v; 16 GB; 288 pin DIMM, 260 pin SODIMM; identified instead by bit rate to MT/s (megatransfers per second)
🗑
|
||||
| What is the advantage to the UniDIMM standard created by Intel? | Compatible for both DDR3 & DDR4. CPU Skylake can handle either DDR3 or DDR4 memory.
🗑
