Memory Help

[Steven Chen_1]

Hello,

I am in the process to add 1G memory to K260 box that has one memory module. From cstm, the following information shows there is one pair of slots left. But I would like to make sure the arrangement.

Here is the report from cstm:

*******************************************

Memory Board Inventory

Total Phys Configured Disabled
Board Size (MB) Total (MB) Total (MB)
------------ ---------- ---------- ----------
EXT0 0a/0b 256 256 0
EXT0 1a/1b 256 256 0
EXT0 2a/2b 128 128 0

EXT0 4a/4b 128 128 0
EXT0 5a/5b 128 128 0
---------- ---------- ----------
System Total: 1024 1024 0

*******************************************

If I add 2x512M there, I have to make room for them to get into the first pair place. Is it right?

It will be very appreciated if someone offer hand on this and other attention point on adding memory.

Steven,

Yes, you need to move EVERY (almost) memory pair down one slot!

like this:

EXT0 0a/0b 512 512 0
EXT0 1a/1b 256 256 0
EXT0 2a/2b 256 256 0
EXT0 3a/3b 128 128 0
EXT0 4a/4b 128 128 0
EXT0 5a/5b 128 128 0
EXT0 6a/6b 128 128 0

Hello,

Install them like this and you should be fine:

0a/0b: 512Mb
1a/1b: 512Mb
2a/2b: 256Mb
3a/3b: 256Mb
4a/4b: 256Mb
5a/5b: 256Mb

You'll have a total of 2Gb memory this way.

Make sure you install them in this order.

HTH,

Hello,

Sorry, my answer should be

0a/0b: 512Mb
1a/1b: 512Mb
2a/2b: 256Mb
3a/3b: 256Mb
4a/4b: 128Mb
5a/5b: 128Mb
6a/6b: 128Mb
7a/7b: 128Mb

You have 2 free, not one.

HTH,
Vince

Hello,

You are buying a pair of 512Mb modules right?

A 512Mb memory module is a 256Mb x 2. So I assume you'll buy (256 x 2) X 2 memory modules.

According to Mr. Brown Jr., that is only 1 pair. If you are buying only 1 pair of 512Mb module, you have to install it LAST, not on 0a/0b as he suggested. You have to install it on 6a/6b. The reason is that memory modules in K-Class are installed in pairs of modules, highest first. If any memory modules are not in pairs, they are installed last, no matter the size.

Vincent,

Good point, Steven says he is installing 1GB, and it is confusing, is it 1GB as in 2 512MB modules, or 1GB as in 4 256MB modules (hence two pairs of 256MB modules).

If it is a pair of 512MB modules, hence a 1GB "memory card", then it needs to be installed as this:

EXT0 0a/0b 512 512 0 --- the new 1GB memory module (really a pair of 512MB cards)
EXT0 1a/1b 256 256 0
EXT0 2a/2b 256 256 0
EXT0 3a/3b 128 128 0
EXT0 4a/4b 128 128 0
EXT0 5a/5b 128 128 0
EXT0 6a/6b 128 128 0


if it is TWO pairs of 512MB modules, hence each pair consists of 2 256MB memory cards, then this would apply:

EXT0 0a/0b 256 256 0
EXT0 1a/1b 256 256 0
EXT0 2a/2b 256 256 0 --- the new 1 512MB memory module (really a pair of 256MB cards)
EXT0 3a/3b 256 256 0 --- the new 1 512MB memory module (really a pair of 256MB cards)
EXT0 4a/4b 128 128 0
EXT0 5a/5b 128 128 0
EXT0 6a/6b 128 128 0
EXT0 7a/7b 128 128 0

THis document describes exactly what is what and how to do it:

As per your posting we could find there are 6 modules 0 to 5. In a single memory carrier you can put maximum 8 modules. So in your case you can add 2 more module. HP memory comes as a module. each module consists of a pair of SIMMS. It is better to ask your vendor to send 1 GB module, if it is available, otherwise 512 MB module also will do the job.

Yes, according others said earlier, you have to put the high density memory first and then you have to put the low density.

Hi Guys,

Thanks a lot for the reply.

I double checked with the vendor who said he offers 2 pairs of 256M, i.e. 4 chips of 256M each.

In this case, I am filling up all slots and need to move 128M pair from 2a/2b & 3a/3b to 6a/6b & 7a/7b, in order to add the new one in 2 & 3 slots.
