Memory check

hi

Is it any tool to check if I have the correct memory (RAM) for my mainboard?

I mean generally not for a special mainboard.

You can use:

yep, I know Memtest86, but this is just a memory test and it needs very long time.

Install the lm_sensors package. Run "sensors-detect" as root. If it detects a supported i2c bus controller on your mainboard and SPD EEPROMs on it, you can use "decode-dimms.pl" to list the properties of your memory modules (manufacturing serial numbers, speed classification, timing values etc.).

Then find the manual of your mainboard/system and verify the requirements of your system.

If the memory works on your system, it is obviously "correct" in some minimal sense. But you'll need the mainboard/system documentation to see if your configuration is optimal or not. Some server systems will display warnings at boot-up if the memory configuration is sub-optimal.

By identifying the chipset used in the mainboard, one might be able to automatically look up a set of requirements for the memory on the system. But the mainboard design may offer extra features and/or restrictions on top of the chipset requirements.

The system BIOS/firmware usually knows the correct memory specifications for its specific mainboard model, but currently there does not seem to be a standard for storing and accessing the specification information. That's why the specifications are not conveniently auto-detectable at the moment.

Hi,

Try using Memory Info tool.

cstm>sel dev (memory dev number>
cstm>info
cstm>il

or

you can get the Memory DIMM Information from SMH

http://:2301 here select Memory.

Thanks
Shiv

CSTM is good option

hp-uxdev# which cstm

hp-uxdev# /usr/sbin/cstm

hp-uxdev# print_manifest |grep -i memory
