[PPC] Some of my ram DIMMs aren't showing up

http://ubuntuforums.org – Hello everybody with powerpc's, I'm looking to find a way of identifying which ram slots are used. Unfortunately I have 3 gigs worth of DIMMs installed but only 1.5GB of memory show up as recognized by /proc/MemTotal or in System Monitor. I found how to do this with intel/amd architecture but it requires the BIOS in the machines to be read with dmidecode. As this is a powermac G5 dual 2.5ghz dmidecode isn't even in the powerpc repositories. How do you all find which ram slots are being used? (Hardware)

Stories similar to [PPC] Some of my ram DIMMs aren't showing up

I've got two Dell PE R710's -

A has a single socket and 3 DIMMs in one bank B has both sockets and 6 (2 banks @ 3 DIMMs) filled

The output from "ipmitool sdr entity 8" confuses me - according to the OpenIPMI documentation these are supposed to represent DIMM slots.

Output from A (1 CPU, 3 DIMMS, 1 bank.):

~#: ipmitool sdr entity 8

Temp | 0Ah | ok | 8.1 | 27 degrees C Temp

I am basically away from my office, but would like to check whether a pc (which has 4GB of RAM) has 4x 1GB DIMMs or 2x 2GB DIMMs.

I am referring to a windows XP system. Is it possible to gather this info from System information or otherwise, remotely?

Thank you for your help

[ubuntu] triple channel checks 1 year 30 weeks ago

Dear all, first of all thank for the great work. I have to perform some memory tests in an intel i7-960 processor but I m not able to find any command that give me an answer of the type numbers of channel that the Integrated memory contol use. I only know that there are 6 memory bank of 2GB. I also try to guess but decode-dimms (after the activation of the eeprom module) gave me 0 module found

Hello-

I have just removed 2 x 1GB DDR2 DIMMS from my desktop and replaced then with 2 x 2GB DDR2 DIMMS.

On boot the Bios reports only 3GB is usuable - this is before the OS boots. There are two OS's, 64 bit Ubuntu and 32 bit XP. Both report 3GB of available RAM.

I recently installed Ubuntu 11.10 64-bit. I also just got two sticks of 2G DDR 400Mhz ECC Reg. Ram for my computer (It requires ECC Reg for anything a Gig and Up) for a total of 6 Gigs. The motherboard is an H8DCE, if that helps.

Anyway, I installed the ram yesterday, and at first it would detect it all in the bios, but not in Ubuntu (Which only detected 4.8).

We got a supermicro server, http://www.supermicro.com/products/system/1u/5016/sys-5016i-ur.cfm, according spec, the server supports up to 32G memory when using ECC Register Memory.

Lubuntu typically has too many problems that have to be sorted out while installing onto a PowerPC machine such as an iBook, Powerbook, or Powermac.

These haven't been solved. I really like Lubuntu and haven't been able to use Lubuntu effectively on my iBookG4.

Now, I found a distribution called MintPPC 11 which has ALL of the problems solved that were found in Lubuntu PowerPC.

Dmidecode 这款软件允许你在 Linux 系统下获取有关硬件方面的信息。Dmidecode 遵循 SMBIOS/DMI 标准，其输出的信息包括 BIOS、系统、主板、处理器、内存、缓存等等。

Dmidecode 应该在主流的 Linux 发行版中都可以找到，因此你只需通过所用发行版的包管理器安装即可，如：

To check what RAM memory type yo have installed (and also see other useful information about your system), do a sudo dmidecode
