K570 Memory Upgrade - Do I need an addittional memory carrier

[Alun Territt]

Existing production box is K570 with 3.5G of RAM. Would like to add another 256Mb of RAM. How can I tell if I need another memory carrier ? - Is there anything else I need to look at ? Many thanks

K570 has initially two memory carriers, memory extender 1 and memory extender 2 and can be populated slot 0a/0b to 7a/7b independently.

It also support up to 8 GB of main memory (Maximum 3.75 GB with a 32 bit OS ) if you used a 512 MB memory module.

Memory greater than 3.75 GB will not be utilized under 32 bit OS circumstance.

If you have a memory carrier populated with 256 MB momory modules, the total size of main memory would be 3.5 GB.
In other words, you need a memory extender "1" to increase the amount of main memory.

Try to use STM (Support Tools Manager) to see the already-configured memory status on memory extenders.

# ioscan -knf
if hardware path for memory is 32, the following will show you the physical configuration on the memory extenders in details.

# echo "sel path 32 ; info ; wait ; infolog " | cstm | more

Hope this helps,

Hi Alun:

To see what size SIMs you have you can do:

# echo "selclass qualifier memory;info;wait;infolog"|cstm > /tmp/meminfo

If you want an easy way to see if you have one or two memory carriers installed, do:

# "selclass qualifier cpu;info;wait;infolog"|cstm > /tmp/cpuinfo

In the modules section of the output, you will see something like:

Memory Carrier 0 Regular
Memory Carrier 1 Not present

Regards!
