4GB memory for M58p

[kristoffer]

I have a Lenovo M58p and it has the Intel Q45 mainboard with a Intel 4500 integrated graphics card.

It came with 2GB of RAM, however I have now bought a Kingston 4GB RAM.

It does not work

The details for the memory are:

KVR1066D3D4R7S/4G

It is PC3 - 8500 CL7 reg

Shouldnt this be supported by the M58p?

I have installed the latest BIOS, which is supposed to have support for 4GB ram "pieces".

?

As I can see in the forum, several people have problems with adding RAM to the M58p (and another Lenovos)

Hello? Noone?

I'm pretty sure the M58p only supports 2gb RAM modules for a total of 8gb supported RAM (doulbe check that, I'm not certian about the 2gb max). Also, the RAM must be of the 16-chip variety rather then the 8.  Also, it's said that you'll get better performace if you install your ROM in identical pairs rather then single modules.

There is actually two anwers for your question "rwbaker", it supports up to 16GB. And 8GB

But the 16GB is DDR2, and only 8GB of DDR3. (it supports both DDR2 and DDR3)
In the last BIOS update, the revision file says it is now supporting 4GB RAM modules.

It does not say anything about DDR2 or DDR3, I didnt think of it either.

The only reason I bought 4GB is that Im pretty shure I will buy 2x more of the same RAM in the future, for a upcoming i7 computer. Seems like I'm closer to this every day...

What is the exactly model?

[kristoffer]

if you are referring to the Lenovo model, it is M58p 6234-A1G

RAM, have no idea but I can check it further

[IPnaSh Guru]

Do you know whick is the Case Latency (CL) of your 2 GB module?

[kristoffer]

I can check later today (when I come home)
The only thing I can find now, is that the part number of it should be 46R3322 (lenovo part number)
I cannot find the CL with Google though.

How many memory slots it has?

If it max RAM memory is 8 GB, and it has 4 slots, so the max RAM module per slot is 2 GB (this it just a quick calcule).

Check this.

[kristoffer]

It does have 4 slots.

I cannot find it now, but it says actually 16 GB max supported RAM (somewhere)

I do have a feeling it is not correct: I think it is:

* MAX 8GB DDR3 RAM, using 4 x 2GB DDR3 modules

* MAX 16GB DDR2 RAM, using 4 x 4GB DDR2 modules.

The M58p is supporting both DDR2 and DDR3 RAM (it says in the manual) so I have a theory this is the way it is.

How can I contact Lenovo to check this out?
