I want to take advantage of the last of the P-IV selloff and get the fastest chip I can to put in my old server. It's a Dell 400sc with a 2.26 GHz, 478 northwood, 875P chipset. I have PC3200 memory, so I think that a 800 MHz FSB will work --- But how do you know if the CPU will work? Voltage is the primary concerm. Does the chip set the voltage on the motherboard or do I have to set it manualy. I have the high capacity heatsink so the dissapation should be OK.
The manual says the box can take a 478 pin processor up to 3.2 GHz so I assume that is a prescott chip.
I think I found some info that may help you out some:
1. What processors does my system support?
The PowerEdge 400SC supports a single processor and been tested, validated and manufactured in these configurations:
Intel Celeron Processor at speeds of 2.0 and 2.4Ghz, 400MHz Front Side Bus (FSB), 128KB cache
Intel Pentium 4 (Northwood) Processor at the speed of 2.26Ghz, 533MHz FSB, 512KB cache
Intel Pentium 4 (Northwood) Processor at speeds of 2.0Ghz, 2.4Ghz, 2.8GHz and 3.4GHz, 800MHz FSB, 512KB cache
Intel Pentium 4 (Prescott) Processor at the speed of 3.4Ghz, 800MHz FSB, 512KB and 1Mb cache.
These processors fit into the Intel "Socket N", 478 pin, ZIFF processor socket.
Thanks ... Neat chart ... I called Dell, they no longer have the upgrade kits.
Maybe you can help me better understand what I am doing, before I blow something up ... Does this mean that any prescott processor, 3.0E for instance could be used? I am still confused as to what exactly can you 'plug in'. How does the voltage get set for the chip? I can't seem to find anything in the manual that talks about setting cpu chip voltage.
I already have on order from ebay Dell's bigger heatsink and fan assembly so ... Which chip should be the better preformer, northwood or prescott? They both now go for around $85 so it's not price that counts, I just want the most I can get from the old girl.
