RAM Questions


I have two options for a server but I am not sure about the notation.

One option is 32 x 2 GB @ a list price of $ 3,519.

Option Two is 16 x 4 GB @ a list price of $ 4,820.


What does the 32 and 16 signify?

Usually that means how many sticks of memory it is: 32 sticks of 2GB each or 16 sticks of 4GB each.

I assume that means you're talking about some very expensive motherboard with sockets for 32 sticks of ram. (Two or four sockets is typical in a workstation, eight in a server. Thirty two is impressive).

Leaving half the ram sockets empty would give you more flexibility to upgrade later (when you decide 64GB isn't enough). But that option costs more now.

4GB ram sticks are harder to cool than 2GB, so maybe that will limit the speed you can choose. But 32 sticks have more capacitance than 16 sticks, so maybe that will limit the speed.

I don't even know what memory nor motherboard technology you're talking about, so I can't give any better than the above vague answer with wrong/generic terminology.

I just looked up a random (not lowest cost) ram choice from NewEgg
(2 x 4GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
for $250
If you were talking about the same memory technology (240-Pin DDR2 800) then your 16x4 choice should be just eight times as much or $2000.
Since you're quoting over double that, it's either a more advanced memory technology or a rip off.

Or did I misunderstand what price you're quoting? Based on the thread title and info I assumed that was a price for ram. But maybe its for a whole server. I really don't have even a sense of scale for what you're trying to buy, other than 64GB of ram.

It would be more useful if you posted a link to exactly what you're looking at, rather than phrases you don't understand from the ad.
