How do I know if my system takes Low or High Density Memory (I am upgrading)? I want to add a stick of 256mb, but do not know whether to get LD or HD.
My system is about 3 years old.
Dell Dimension XPS T450 Mhz, Pentium 3.
Thanks in advance.

My bet is low density.

Does it really matter?

Many older motherboards cannot accept high-density RAM. An example would be a 256MB DIMM with all chips on one side of the PCB.

So HD just means that the chips are packed closer together?(and in this case on one side?)thanks:t

no. it means the capacity of each chip is higher. if you're gonna add a 256, it would probably have to be double sided. you might want to check with dell or go to www.pny.com and use the configurator. your system may only take up to 128mb dimms.

Like they said hd is basically a bigger capacity mem chip (not larger physically). Its has more cells to it then low density hence high density mem chips. This causes probs. on older systems as it doesnt know how to address that many mem cells per chip. each mem cell holds one bit of data. This will either be a 1 or 0 representing "on" or "off" like a switch. This is binary lang. which all pc's use. Hope that helped explain!:t

Also try the memory configurator at www.crucial.com

Thanks for all the responses.
I have tried the configurator at Crucial.com and it says that I can accept 256mb, but apparently not 512.

Now I just need to decide what video card to upgrade to. :)
