HollidayGamer :
When I tried to upgrade my cpu from intel pentium 4 3.00 ghz to intel pentium dual-core 2.7 ghz I ran into a problem... When the dual-core cpu is in the computer automatically powers on when power supply is plugged in and the fan spins at highest setting. I tried to find a bios update with single-core cpu but mine seems to be up to date. I don't have a clue what to do. Thanks for the support
HollidayGamer,
The Dell Precision 390 was made with three, proprietary motherboards: 0DN075 (most common), 0GJ911, and 0MY510. These are all Socket LGA775 and support a variety of single, dual, and quad-core CPU's of 65nm lithography. These include Pentium 4 (1-core), Pentium D (2-core), Core2 Duo (2-core), Core2 Quad (4-core), Core2 Extreme X6800 (2-core), and Xeon X32xx-series (4-core).
If you have not been able to run a new CPU, check that it is within the proper series of 65nm lithography. There are a lot of tempting 45nm LGA 775 CPU's and these, which also support 1333 RAM will not work.
The fastest CPU's in Passmark benchmarks:
Core2 Quad Q6700 (2.66GHz)
Core2 Quad Q6700
Xeon X3230 (2.66GHz)
Xeon X3230
Xeon X3230
> and the lowest CPU performance are Pentium 4 and Pentium D which is essentially a pair of Pentium 4's.
My recommendation is either Core2 Quad 6700 or Xeon X3230, and leaning a bit towards the Xeon, though they're a bit less common.
RAM: Up to 8GB of DDR2 1066 ECC and non-ECC RAM. You'll find that the 4-ECC or non-ECC slots have the gap in the pins in a different location so that the type can't be changed. When buying memory, it's best to take the numbers off a module of working RAM and find the closest designation.
I upgraded a Precision 390 that was a gift and the results for a $125 total were very encouraging, making a system that runs current 3D CAD software and Adobe CS at acceptable levels.

My pending upgrade to this system is to add a PERC 6/i SAS /SATA RAID controller and 146GB and 300GB 15K SAS drives. These disk components were taken from a Precision T5500 (which is getting a 6GB/s LSI PERC H310) and should improve the disk performance substantially. In the T5500 (Xeon E5620, 1333RAM) the PERC 6/i and 15K drives, the Passmark disk score was 1208.
With careful shopping, the Precision 390 can be a good performing highly reliable system at a low cost.
Cheers,
