Simply because the bandwidth is greater with PC1066 and you do not need as much memory. Straight from Dell's mouth.

Dell's mouth is wrong. The amount of memory you need is independent of the memory speed. If the application doesn't fit, then you basically run at the speed the hard drive can swap, which is much slower than even PC100 SDRAM! There are very few people for which 1.5GB would be a problem. Most people probably wouldn't see a speedup with more than 256MB of RAM. If someone really needs RAM, then buy the Precision 530 Workstation which will take 4GB (as well as dual, hyperthreaded Xeon processors!)

I'm glad you noticed this is what Dell said and not me. I did call and this was the answer Dell gave me. As far as I'm concerned, who needs 1.5Gb of memory? 

Few people indeed. I run some CAD applications and have never used more than about 400MB. I've got 512MB on those systems. If somebody truely does have a program that needs 2GB, then they would be MUCH better off with a 8200 than an 8250, no matter what Dell says!

(I take it somebody disagrees with me because of the 1-* vote. :-()

Talmy,

Some of us have our star givers receivers turned off!!!    :)

I didn't like the idea of the stars either, but haven't given up yet.

You probably received the 1 star because you posted a response that had very little to do with my original question.

I wanted to know why the 8250 only supports 1.5 GB of PC1066 while it can take 2.0 GB of PC800.

You responded with comments about who needs that much memory ... which was not relevant.  Sorry.

Thank you anyway for the input.

 

Not to be a jerk, but does this really matter??

Oh and about the 1+ GB of memory. Now you say you dont need that much. But in the future you will think it ist enough. Like HD's back then 500 MB was a lot, now 80 GB isnt enough.

Thank you for the response.

So ... can one conclude that PC800 uses less power and creates less heat?

Please advise.

 

1)  Dell Dimension 8250's are configured with 250-Watt power supplies.  They do not have enough power to run 2GB of PC1066 RDRAM and provide platform stability.

2)  Dell Dimension 8250's do not provide good thermal management...  Not enough case fans to dissipate the heat generated from 2GB of PC1066 RDRAM.
