Which Memory for DELL 2.8 800 FSB???

[Jhoulihan]

I just bought a Dell server (400SC) with a P4 2.8/800FSB processor for a great price. I currently have PC2100 DDR Ram chips made by Crucial and I'm wondering if they will work in my new Dell.

The new one comes with 128MB DDR, ECC, 333MHz RAM.

Should I buy another 512MB of DDR, ECC, 333MHz RAM?

Or

Should I install my current 512MB PC2100 DDR Crucial chip along with the new computer's 128 MB chip?

I really know nothing about the current memory technology but I am very interested in getting fast performance and Hyperthreading which is the only reason I upgraded to the new Dell. I probably won't be overclocking.

Any help or suggestions are appreciated.

Thanks,

Jerry H.

I'd swap the 333Mhz for 512 MB PC3200 or PC3500
