More than 4GB in XPS M1530?

I have Vista 64 bit on my M1530. I wonder if it is possible, now or in the future, to install more memory (more than 4GB) in there? I'm not interested in whether it's worth it or not, just curious if it is possible now or perhaps in the future?

 

Of course. 64-bit OS can utilize theoretically limitless amounts of memory. Just have to wait for them to release larger than 2GB sticks for notebooks, but by then, your m1530 will probably be obsolete.

 

As far as I know, the physical limitation of the chipset is 4GB of RAM. Don't count on it being higher.

 

Any that is my question... is there a hardware limit in the XPS M1530 that would prevent 8GB if such memory was to become available?

 

There very well could be. If you use CPU-Z, you can ID your chipset and find out the specifications of it.

 

Yes the Chipset in the M1530 will only support 4GB. The GM/PM 965 chipsets have a limitation of 2 sodimm slots at 2GB each.

BUT... If you can find 4GB modules with double density chips it should work. Double number of chips will not work.

 

There *might* be a problem with the number of address lines. 4gb SO-DIMMS are rare, so we'll have to see if they can work in the Santa Rosa machines.

I certainly hope so; it would be nice to have 8gb on my laptop eventually.

 

Is there a 4gb RAM stick? Might cost an arm and a leg.

 

There's 3 limitations you have to overcome.

1. BIOS. Current BIOSes are limited to 4 GB, but luckily, BIOSes are upgradable.
2. Chipset. Santa Rosa chipset is limited to 4 GB. This cannot be upgraded.
3. Motherboard. Your motherboard will only recognize so much RAM. This cannot be upgraded (short of getting a new mobo of course).

 

Santa Rosa is 36Bit and can address 64GB. It's in the specs on the Intel site. Found out today after researching the issue a bit more.

And this other document from Intel states 8GB support for the 965 Chipset.

It may or may not work with 2x4GB dual density modules. The issue is getting the modules for testing this...

 

With Montivena and DDR3 clips on the horizon, I wonder if they are going to make any new DDR2's with larger capacity...

Although it'd be very nice to have.

 

The 4Gb module do exist.

Finding them at a reasonable cost is another story... The cheapest I saw so fay is over $700 each module!

 

Ahh, nice.

So theoretically, if one's willing to fork out an extra $1500 bucks now, he should be able to enjoy the luxury of 8G of ram...

 

Ill do it for the team!

 

Your system supports up to 4GB RAM only.
