RAM for Studio Xps 16

Hey

Anyone upgraded his RAM memory in its Studio XPS 16?

I'm wondering what's a good brand, price, and all the tech stuff. Any advice?

I got original 4GB and thinking to go to 8GB.

Thanks

 

still a tad expensive though

Yeah I would hold out on upgrading, its a lot of money. There's very few brands that are making this type of memory yet (because there's very few i7 laptop models).

 

It's just not really in much demand yet, but some core 2 laptops actually use DDR3 also.

 

The XPS 1640 needs at least 1066MHz DDR3 memory and the 1645 at least 1333MHz. You can also use memory capable to run at higher frequencies, but it will only be clocked at 1066MHz or 1333MHz.

I usually buy Corsair or Kingston Ram when upgrading Laptops and never had problems with it.

 

You don't "need" any speed of memory at all. All that will happen is either the memory will be slower or you'll be wasting your money when it can't clock it at it's supported rate. If I wanted to I could clock the memory in this to, for example, 800mhz and it would run fine

 

You cannot change the memory clock in the bios setup. I am not sure what happens if you use too slow memory. Maybe it will be automatically clocked down or maybe it won't work at all. Faster memory always works and the price of 1066MHz and 1333MHz memory modules is almost equal. You could only waste money when buying 1600MHz modules.

 

The bios reads the memory speed from the SPD and sets it accordingly. It will work with faster or slower memory and just clock to the fastest that both the system and the ram will run at. So 1333mhz ram in a 1066mhz system will clock the ram down (and maybe even drop the timings a bit too, but it depends on what's in the SPD for the 1066mhz speed) and 1066mhz ram will just run at 1066 in a 1066 system, etc. This is nothing new or special, and it has worked like this since at least when the first gen 66mhz SDRAM came out on Pentium II's.

For fun, go run CPU-Z and it will show you the SPD values on your memory chips, you can see that they will generally have several profiles for various clock rates.

 

What will happen if you put 1066 MHz memory in a 1333MHz Laptop? Bios may downclock the memory after reading the SPD information or just say wrong memory type and prevent the system from booting.

 

i think it would definitely boot and run in the highest clock rate which is supported by the memory and by the motherboard (1066 mhz)
