Dell Computers picky about types of RAM?

Any P4 RDRAM system must take memory in pairs - its dual channel.

The 8250 has dual-channel memory access, it writes to two memory modules at the same time to double the memory access speed, more memory speed = more system performance

To do this the memory memory must be the same size per memory bank (2 modules) and all the memory must have the same speed (PC1066 RDRAM).

You can however use PC800 RDRAM but you lose system-performance this way!

I'm just wondering why are dells so picky about what type of RAM you purchase.  As you see in my sig, i have a dimension 8250 with RDRAM.  But if I upgrade my ram, why do i have to purchase Ram in doubles? So can you put in PC800 RDRAM into a PC1066 RDRAM comp? Thanks for replying. I appreciate it.

Thanks for responding.  I have another question.  Why can't i get RDRAM from Crucial or any other memory provider?  Am i making any sense here?   I'm confused of which maker to get ram from.  Thanks.

Crucial does not sell RDRAM as they do not have a license from Rambus to sell it.  Crucial is owned by Micron Technology, one of the largest manufacturers of memory.  They don't make RDRAM.

Kingston and Samsung are two of the leading sellers of RDRAM.  The links I provided to you, and provide here again, give you the EXACT Samsung modules for your computer that will work.  You should at least use the link to get the part number for the module you want.  

 I've gone to Googlegear.com and selected Samsung memory for specific Dell systems and provided the links. Googlegear has great prices. Remember to buy two matching sticks. If you don't want to buy them from Googlegear, you can use the part numbers to find them elsewhere. To find the proper RDRAM for your computer, click here.

Rick,

Thanks for replying.  I appreciate it.  I hope the on-going suit against Rambus is settled.  Again, thanks for repying.

I bought Samsung memory from memorysuppliers.com and it worked out great. The stock RDRAM used by Dell is made by NEC. Don't buy it from Dell because you can save 50-80 dollars if you buy it from somewhere else. Dells use a lot of Samsung components so I'm not surprised at all that Samsung memory works well in them. I think most computers these days use non-parity memory which I think is what I got.
