I just recently purchased and installed an Intel Northwood Pentium 4 Socket 478 P4 3.06 GHz 533 Mhz 845 Chipset Upgrade to my old Dell Dimension 2400. It was properly installed, along with reinstallation of the heat sink and fan.
Upon starting up the system, I get 6 beeps and Diagnostic Lights show A, C green and B, D are amber - the diagnostic pattern from Dell indicates:
"Memory modules are detected, but a memory configuration or compatibility error exists." and their solution is:
"1 - Ensure that no special memory module/memory connector placement requirements exist.
2 - Verify that the memory modules that you are installing are compatible with your computer.
3 - If the problem persists, see "Contacting Dell" in your Owner's Manual."
I have the original PC3200U-25330 512mb ddr-4000mhz-cl2.5 sticks from the factory installed. I tried to reinstall them one at a time, but to no avail - still the same 6 beeps and Diagnostic Lights.
Do the RAM sticks need to be compatible with the new processor or am I missing something?
