I am currently looking for a new pc and I was compiling a system on the Dell Website when I encountered the following prices:

2.048 MB 667 MHz Dual Channel DDR2 SDRAM [2 x 1.024] [inbegrepen in de prijs]
3072MB 667MHz Dual Channel DDR2 SDRAM [2x1024/2x512] [meerprijs € 70,00 of € 3/maand-1]
4.096 MB 667 MHz Dual Channel DDR2 SDRAM [4 x 1.024] [meerprijs € 140,00 of € 6/maand-1]
2.048 MB 800 MHz Dual Channel DDR2 SDRAM [2 x 1.024] [meerprijs € 80,00 of € 3/maand-1]
3072MB 800MHz Dual Channel DDR2 SDRAM [2x1024/2x512] [meerprijs € 150,01 of € 7/maand-1]
4096MB 800MHz Dual Channel DDR2 SDRAM [1x1024] [meerprijs € 300,00 of € 13/maand-1]

The memory on the first line is included, the prices next to the other lines are what one pays as surplus should one choose these options. I am not really familiar with harware prices but am I correct that prices are really high? For example if you look at the difference between line 1 and 3 you can see that 2x1024, 667MHz costs €140. I believe I can find 2x2048 for the same amount of money or am I missing something here?

Also, on a related note, Is the difference between 4x1024 substantional in comparison to 2x2048?

Thanks in advance

Are you kidding? Well of course it is more expensive. Let me kindly remind where you are.....you are on the DELL Website, buying from DELL.
But then you are paying Dell to install it, and guarentee it.

2x2gig or 1x4gig. For enthusiasts, fewer sticks mean fewer problems with overclocking. It can be very tough to overclock or even get fast/low latency memory to run at it's advertised timings when using 4 modules.

Using only 2 modules stills leaves room for later upgrades.

Just get what you need now (2GB) and if you want more go to Crucial and get it up to 75% cheaper.

It's true. As much as I like Dell, their "upgrade" prices can go through the roof. You're better off to take the best deal going at the time and then purchase your upgrades elsewhere.

Don't forget to checkout Outlet.Dell.Com

They is where I buy all my Dull Laptops.
Much cheaper.
