openSUSE 12.3 __64
KDE 4.10.5 r1
To my Toshiba Satellite Pro Laptop.
It has 2GB now.
From what I have read everywhere, 4Gb is the max and that is what I bought.
Is the 4gb max a hardware thing or was that due to the restrictions in Windows ?
I am just curious.
You can have way more memory than 4 GB using openSUSE 64 bit. I think I read it was 256 terabytes of physical RAM, but the actual hardware, in this case your Laptop, would determine the limit. I would need the full laptop model number to look that up. For a single session machine, not running VM’s much, 4 GB is all you would need for sure. If you are big into VirtualBox for instance, you would want more I guess.
That You,

Hi
You can check this via the command dmidecode, for example on this
machine;
dmidecode -t memory
# dmidecode 2.11
# SMBIOS entry point at 0xbc66e718
SMBIOS 2.6 present.
Handle 0x0005, DMI type 16, 15 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 8 GB
Error Information Handle: Not Provided
Number Of Devices: 2
So under Maximum Capacity this system can handle 8GB (which is what is
installed…)

I do not now what you mean with “everywhere”, nor what they were talking about there. When that is about your hardware make and type, they will probably be correct. I personaly would search in the website of the maker to see the hardware specifications and not “everywhere”.
For openSUSE it is no problem. Just put the memory carefully into it’s sockets and reboot.

It is a hardware limit (CPU and motherboard). You should not read
“everywhere”, but only on the manufacturer data sheet for the model you
have. What “everybody” says is irrelevant.

Sorry for being so “generic”. By everywhere I meant the Toshiba site and at least 3 other memory manufacturers. Crucial, Kingston, Mushkin, and G.Skill.
They all say 4gb max, so that’s it. 4Gb G.Skill memory has been shipped.
This illustrates what I love about Linux. If there is something that I want to know about my PC, there will be a linux command line, or script, or, that will tell me what I want to know.
Like dmidecode. Though the output is a bit daunting to read.
Thanks guys.

Hi
So what did it say about the max memory?
I had a DELL E5510 that said max 4GB in the specs, dmidecode showed
8GB, stuck 8GB in and it worked fine (and used it as well…)

Well, it says here that 2GB is the max. And you have 2 1GB RAM bars mounted now. One will be hard to replace, since in Toshiba’s the first “slot” is mostly soldered to the motherboard.

Hi
Doesn’t look good for your 4GB, is there a BIOS update available for
the system, if so update and check again.

How odd. I opened the small door at the back and there were 2, 200 pin memory sticks in what looked to be flip out slots. Each says 1gb samsung and a bunch more numbers. It looks to me that the new, 2gb sticks will slide right in.
We will see.

I do not trust the output of that program. In my case it says:
Telcontar:~ # dmidecode -t memory | grep Maximum
Maximum Memory Module Size: 4096 MB
Maximum Total Memory Size: 16384 MB
Maximum Capacity: 4 GB
Telcontar:~ #
The real maximum, per the board datasheet, is 8 GiB, and that is what I
have installed.

That doesn’t actually matter. If the electronics can’t handle the higher
density of memory, the sticks just won’t work. Just because it’ll fit
doesn’t mean anything.

As I understand it this all depends on the motherboard and it’s “wiring” plus chips so it’s difficult to see how any software can physically read what is actually there. What tends to happen is that the address lines needed to decode the memory banks are simply not connected past some point. The same thing can be done in the memory slots as well.
I also understand that from time to time people have found that slots will take more than the manufacturers state that they can. I’d say that is most likely to happen when they also produce a “better” version of the same item. On the other hand bigger chips than they state may work. There is just some risk that they wont.
:(I have a net book that should have 4gb. Turns out that they were produced with 2gb for some retailers. Wish I could open the thing to change the sticks.
