ram

mikeyd1985 · 09-08-2009, 05:29 PM

I'm buying more ram for my computer and was wondering how I get all the info on my current ram. I use the lshw command and this is what I get:

*-bank:0
description: DIMM DRAM Synchronous
physical id: 0
slot: S1
size: 512MiB
width: 32 bits

but I want to find out if it's DDR or DDR2, and if possible the spd without having to open the computer. Any suggestions?

There should be a little more information there:

Quote:

*-bank:0
description: DIMM 400 MHz (2.5 ns)
product: None
vendor: None
physical id: 0
serial: None
slot: A0
size: 1GiB
width: 64 bits
clock: 400MHz (2.5ns)

The clock speed will do a lot to narrow down your choices.

Do you mean like these?

Code:

Handle 0x000B, DMI type 17, 27 bytes
Memory Device
        Array Handle: 0x000A
        Error Information Handle: No Error
        Total Width: 64 bits
        Data Width: 64 bits
        Size: 512 MB
        Form Factor: SODIMM
        Set: None
        Locator: DIMM #1
        Bank Locator: Not Specified
        Type: DDR2
        Type Detail: Synchronous
        Speed: 667 MHz (1.5 ns)
        Manufacturer: AD00000000000000
        Serial Number: 00007239
        Asset Tag: Not Specified
        Part Number: HYMP564S64CP6-Y5

try:

#dmidecode

thanks for your replies.

lazlow- i did lshw again and that is still the only info it will give me. I have to access the bios in order to get the speed.

hurry_hui- the dmidecode command gave me the extra info i wanted.

Handle 0x001F, DMI type 17, 27 bytes
Memory Device
Array Handle: 0x001E
Error Information Handle: No Error
Total Width: 32 bits
Data Width: 32 bits
Size: 512 MB
Form Factor: DIMM
Set: 1
Locator: S1
Bank Locator: Bank 1
Type: DRAM
Type Detail: Synchronous
Speed: Unknown
Manufacturer: Not Specified
Serial Number: Not Specified
Asset Tag: Not Specified
Part Number: Not Specified

it's weird that it says the speed is unknown. when i go into the bios it says the memory bus speed is 667Mhz. from what i just read about the dmidecode is it gets it's info from the bios. Is the "speed", "clock" and "memory bus speed" the same thing?

DDR tops out at 500, so my bet is that you are looking at DDR2.

I looked at it again and I must've misread. It doesn't tell me if it's ddr or ddr2. what the heck, why doesn't it work for me lol. thank you lazlow.
