rp5470 (L3000) memory upgrade

Hi,
I have an RP5470 L3000 server which needs a memory upgrade. It currently has a memory carrier with 8 sticks of 512mb memory for a total of 4gb of memory. I need to increase the memory to 8gb total. Can I add a second memory carrier with 2 x 1gb memory modules and 4 x 512mb memory modules? or do I have to add 8 more sticks of 512mb?

I tried the configuration of 2 x 1gb and 4 x 512mb, but the machine failed upon start up testing. I don't know if the error is the result of the configuration or a bad memory carrier. I went with this config because I only had 4 sticks of 512mb.

Thanks for your replies.

Re: rp5470 (L3000) memory upgrade

Hi,
What was the error message?
In rp5470, you can have single or dual memory carrier. You should put higher density modules in 0a,b then 1a,b and so on.
You can have both 1GB/512MB/256MB. But each module (pair of two DIMMS) must be same.

To support newer memory modules and to support different refresh rates you must have latest system firmware.

Did you follow the above rules? Post your firmware version. (Use cstm to find out)

Re: rp5470 (L3000) memory upgrade

I put the two 1 gb sticks in slot 0a, 0b and then the 512mb in 1a, 1b, 2a, 2b. I don't know the firmware. The system is offsite at this moment. Should the memory carrier with the higher (1gb sticks) memory be in memory slot 0 as opposed to slot 1?

Re: rp5470 (L3000) memory upgrade

Yes You are correct, Memory carrier 0 to have bigger modules. I faced similar issues when I mix diffrent refresh rates. Though all the modules are same, if the refresh rate is different it won't work with earlier firmware.

Hi Eric,

make sure the firmware is version 44.12.
You won't have problems with differnet refresh rates.
Use support tools managers (mstm) info tool and run info on system item. grep for "PDC Firmware Revision:" to find your version.

Hope this helps!

BTW, look for PF_CARIW4412 to find this version in itrc and follow the instructions.

Re: rp5470 (L3000) memory upgrade

Eric,

The memory should be configured this way:

Carrier 0 slot 0a/b = 1gb
Carrier 1 slot 0a/b = 1gb
Carrier 0 slot 1a/b = 512mb
Carrier 1 slot 1a/b = 512mb
Carrier 0 slot 2a/b = 512mb
Carrier 1 slot 2a/b = 512mb

and so on.

What are the chances...

Re: rp5470 (L3000) memory upgrade

It is best to use two memory carriers, even if one isn't full, because adding the second memory carrier double the total memory bandwidth. The more CPU's you have the more important this becomes.

Re: rp5470 (L3000) memory upgrade

Hi Eric,

I did RAM upgrade to my L2000 Server

1) had 4 installed, Each is 512 like this
get the mem info
echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

DIMM Slot Size (MB)
--------- ---------
0a 512
1a 512
0b 512
1b 512
--------- ---------
System Total (MB): 2048

2) I Inserted 2 more, Each 1024

You MUST Install Higher Capacity in the LOWEST SLOT NUMBERS.

The order you install must be 0a 0b, 1a 1b, 2a 2b 3a 3b etc.

3) since you have 512 already there, you must look and verify the doc to make sure HIGER capacity in the LOWEST SLOTS and the ORDER.

with this it will not WORK.

AFter Install do

echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

DIMM Slot Size (MB)
--------- ---------
0a 1024
2a 512
1a 512
0b 1024
2b 512
1b 512
--------- ---------
System Total (MB): 4096
