It depends on your motherboard.
It likely uses either DDR or DDR2 memory, and the speeds that are supported vary by the make and model of your motherboard.
It doesn't support more than 4gb of RAM.
The Pentium 4 currently ranges from 1.3 GHz to 3.8 GHz.
The fastest "classic" Pentium is clocked at 200 Mhz. The fastest Pentium with MMX extension is clocked at 300 Mhz. The fastest Pentium II is clocked at 400 Mhz. The fastest Pentium III is clocked at 1.4 Ghz. The fastest Pentium 4 is clocked at 3.8 Ghz. The fastest Pentium D is clocked at 3.7 Ghz. The fastest Pentium M is clocked at 2.26 Ghz. The fastest Pentium Dual-Core is clocked at 2.5 Ghz.
Some motherboards will have the ability to overclock the FSB (Front Side Bus) and make the processor run faster. Many do not, however, and thus the Pentium III can only be run at it's rated speed.
The 3.2 GHz processor is slightly better. Please note that all 3.2 GHz Pentium 4s support Hyperthreading, so the 3.2 GHz isn't in any way disadvantaged.
No, in most cases, the Intel Pentium 2.4 outperforms the AMD Sempron 2500+
Processor: Intel Pentium 4 1.3 GHz or AMD Athlon XP 1500
All CPUs branded "Pentium 4" are single-cored.
Yes, it can support Pentium 4 2.60 Ghz microprocessors.
Intel Pentium 4 refers to a single core running at 2.0 ghz of processing power while a core 2 duo running at 2.0 ghz means 2 separate cores each runnin at 2.0 ghz giving you a total of 4.0 ghz of processing power
Yes.
Socket 478
it seems celeron is better unless Pentium has 2 cores
