Memory Modules

Question 1

What is a single bank module?

Answer 1

You can install one RAM stick at a time, and each slot works independently

Question 2

Can you put an 8GB Ram in on slot and a 4GB in another if the modules are single bank?

Answer 2

Yes, cause each slot works independently of each other

Question 3

What does DIMM stand for?

Answer 3

Dual Line Memory Module

Question 4

How many pins are usually in DIMM connectors

Answer 4

240 or 184 pin connectors

Question 5

What is DIMM exactly?

Answer 5

Its the form factor of the memory module?

Question 6

What does DDR stand for?

Answer 6

Double Data Rate

Question 7

What is DDR exactly?

Answer 7

A memory technology used in memory modules, example DDR3 or DDR5

Question 8

What is PC133?

Answer 8

A 133 MHz older SDRAM (SDR SDRAM) speed standard, used pre DDR technology

Question 9

What is throughput?

Answer 9

The amount of data transferred per second, calculated from bus speed and data bus width.
Throughput = Bus speed × Bus width
How often × how much

Question 10

What is DDR4?

Answer 10

fourth generation DDR tech

Question 11

What is Dynamic RAM (DRAM)?

Answer 11

The oldest common type of main memory that requires frequent refreshing.

Question 12

Why does DRAM require refreshing?

Answer 12

Because each DRAM storage cell is dynamic and loses charge over time.

Question 13

What does DRAM stand for?

Answer 13

Dynamic RAM

Question 14

What does SRAM stand for?

Answer 14

Static RAM

Question 15

Why was static RAM made?

Answer 15

To solve the issue of constant refreshing of DRAM (Expensive process)

Question 16

What was the first type of memory module to run at the same speed as the
motherboard bus?

Answer 16

Synchronous DRAM (SDRAM)

Question 17

How many pin connectors are in Synchronous DRAM (SDRAM)?

Answer 17

168-pin connector

Question 18

What are the common naming conventions for Synchronous DRAM (SDRAM)?

Answer 18

● PC66 (66 MHz bus)
● PC133 (133 MHz bus)
● PC266 (266 MHz bus)

Question 19

What does DDR SDRAM stand for?

Answer 19

Double Data Rate Synchronous Dynamic Random-Access Memory
-RAM
–DRAM
—SDRAM
—-DDR SDRAM

Question 20

What does DDR SDRAM do Better than SDRAM

Answer 20

Doubles the transfer speed of an SDRAM module

Question 21

PIN connector count on DDR SDRAM?

Answer 21

184-pin connector

Question 22

What is DDR2 SDRAM?

Answer 22

A second-generation DDR SDRAM with higher latency and faster external bus access.

Question 23

How many pins does DDR2 use?

Answer 23

240 pin connector

Question 24

Q: What does PC2-4200 mean?

Answer 24

A: A DDR2 memory rating indicating ~4.2 GB/s throughput.

Question 25

Q: What is DDR3 SDRAM?

Answer 25

A: A third-generation DDR SDRAM that runs at lower voltage and higher speed than DDR2.

Question 26

Q: How does DDR3 compare to DDR2?

Answer 26

A: DDR3 uses lower voltage and provides higher throughput.

Question 27

Q: What does PC3-10600 mean?

Answer 27

A: A DDR3 memory rating indicating ~10.6 GB/s throughput.

Question 28

Q: Why can’t DDR2 and DDR3 be interchanged?

Answer 28

A: They have different electrical requirements and different keyed pin layouts.
