Issues related to RAM, Please respond to these

Asked By Mariana D Graham 0 points N/A Posted on - 07/08/2014

I have following queries related to RAM? Could anyone please explain them?
1.] What's the difference between DDR PC 2100, DDR PC 2700, DDR PC 3200 & DDR PC 4000 RAM modules?
2.] How to determine the frequency of your RAM module if it's not written in the module. I mean how to determine if it's 266 MHz or 400 MHz?

3.] What will be the impact on performance of using two DDR RAM modules of different frequency, say 400 MHz and 266 MHz?
4.] Is 533 MHz, RAM module a DDR2 RAM module?

Issues related to RAM, Please respond to these

Mariana,

Below my comments to each of your inquiries:

1. The differences are related to the maximum rate for data transference in Mbytes/second or Gbytes/second .See the info below:

Standard name	Bus clock	Memory clock	Data rate /second	Module   denominat.	Max. Transfer. capacity
DDR-200	100 MHz	100 MHz	200 Millions	PC-1600	1600 MB/s (1,6GB/s)
DDR-266	133 MHz	133 MHz	266 Millions	PC-2100	2128 MB/s (2,1GB/s)
DDR-333	166 MHz	166 MHz	333 Millions	PC-2700	2656 MB/s (2,6GB/s)
DDR-400	200 MHz	200 MHz	400 Millions	PC-3200	3200 MB/s (3,2GB/s)

 

2. You can check it on your BIOS screen. The bios is the program of your motherboard. Most computers access to BIOS by pressing F2 key a couple of times once your computer power on. In other brands of computers, you need to press the delete key two or three times on the power on. Depending on your BIOS you can move along the menu on the screen to look for your memory information.

 

3. A faster RAM module can work on slower bus systems, but will adjust to that speed, this is the 400 MHz module will run at 200 MHz.

 

4. DDR is a configuration that depends on the motherboard socket. Here is a picture for all DDRs

I hope this helps
