| Why does my PC3200 ram only run at 266Mhz? My motherboard can support 400MHz DDR and I imagine a P4 2.0Ghz processor could handle a higher speed. |

PC3200 Ram, should be running at 200Mhz dual pumped or effective (400Mhz) your bios will show it as 200Mhz. So if you Bios is telling you its running at 266Mhz that means you have it over clocked to the effective speeds of (533Mhz) PC3500 Ram.
Hope this is enlightening.

| if you have a Celeron processor, your RAM will be that slow. Even if your motherboard and your RAM can handle higher speeds, it will still run at 266 Mhz because your processor is cheap |

| Could you provide a source for that information because you formulate it rather clumsily. |

well, the Dell site says this:
Quote: *original Dutch text below
DDR333 works at a speed of 266 Mhz with a Celeron or Pentium 4 2.2 Ghz or lower processors and at a speed of 333 Mhz with Pentium 4 2.4 Ghz or higher processors.
(DDR333 werkt met een snelheid van 266 MHz bij Celeron-processors en Pentium 4-processor van 2,20 GHz, en met een snelheid van 333 MHz bij Pentium 4-processors van 2,40 GHz en hoger. )
Intel's older processors use a different system for handling with the RAM, so it's slower.

Yeah, but it doesn't depend on the CPU being a Celeron like you made it sound, a Celeron 2.4Ghz should handle DDR333 fine. My Celeron Mobile 1.4Ghz (comparable to 2.4+Ghz P4) for example supports up to 400MHz RAM speeds.

Of course, Celeron Mobile is different.
I kind of made it sound like the problem is Celeron, cuz i have a Celeron myself and i hate it |
