rx4640 main memory info
hi,
How can I read the SPD info of the memory modules installed on my RX4640 server?
It is said that that info can be found via sysfs which is like "/sys/bus/i2c/drivers/eeprom/", but nothing like that appear on my box.
I also tried to install lm_sensors (linux kernel 2.6.9), I guess this would help to find out the SPD device, but no sensors detected at last.
I would like some detailed info about the memory such as bank, timing, etc.. Any document about that would also be appreciated.
Thanks.

Re: rx4640 main memory info
Have you tried "lshw" or "dmidecode"?
I would try them and see what information it can provide about memory SPD on this box.

Re: rx4640 main memory info
The only output of "lshw" about the memory is
*-memory
description: System memory
physical id: 0
size: 15GiB
While "dmidecode" is better, it can find out there are 32 DIMMs, each one is 512M in size. I grab one of the DIMM's info below. The other 31 are look the same.
Handle 0x0013, DMI type 17, 27 bytes
Memory Device
Array Handle: 0x0012
Error Information Handle: Not Provided
Total Width: 72 bits
Data Width: 64 bits
Size: 512 MB
Form Factor: DIMM
Set: 1
Locator: DIMM 0A
Bank Locator: Rank 0
Type: DDR
Type Detail: Fast-paged Synchronous
Speed: Unknown
Manufacturer: HP
Serial Number: 61c1f27
Asset Tag: Not Specified

Still there is no bank and timing info.
