CPU upgrade for Compaq SR1220NX Desktop


Here are the CPU specs that will help you find a new CPU for your desktop:

Socket 478 for Intel P4 Williamette and Northwood processors

  • Supports Intel Pentium 4 processor up to 2.8 GHz
  • Supports Intel Celeron processor up to 3.06 GHz (Prescott based Celeron with 533MHz FSB)

CPU upgrade for Compaq SR1220NX Desktop Computer


Hi
The specs for this machine state that it is a motherboard with
"Socket 478 for Intel P4 Williamette and Northwood processors
Supports Intel Pentium 4 processor up to 2.8 GHz
Supports Intel Celeron processor up to 3.06 GHz (Prescott based Celeron with 533MHz FSB)"
In other words, any CPU that is not socket 478 ( a fairly old socket now) will not even fit on the board. You do not mention your current CPU so you need to compare it with the spec above to see if you can improve it. It is an old machine/motherboard, so your money might be better going towards a motherboard or system box upgrade.
Cheers

I have an Intel Celeron D 2.26GHz Socket 478 256 k /FSB 533. Is it possible to replace the Pentium 4 1.6GHz in the Vectra with the Celeron. If so what steps would I take and will I have any XP COA...


You need to check with the motherboard maker. A manual would tell you and you might be able to get the info online if you search for the above model number, find the manufacturer and look up the specs. It needs to have the same socket(form factor) and support the bus speed of the new one.
Replacing a CPU is straightforward but non trivial.

Motherboard ID Motherboard Name Compaq Evo


as long as it is a socket 478 processor which narrows it down to P4 or celeron ( P4 being better and faster ) it should be fine.
Obviously it will state what processors it can handle in the computer manual so if you find the manual it should state in there.
I dont think it will handle more then a 3ghz P4

Cpu upgrade


To upgrade the cpu, you will still need to use the same type of cpu. A socket 478 motherboard will not work with a socket 775 processor. The pin configuration is different.

CPU Upgrade-Which Sockel?


Here is some information may be useful to you. Intel processors Socket 1 169 pins 486 SX/DX Socket 2 238 pins 486 SX/DX/DX2 Socket 3 237 pins 486 SX/DX/DX2/DX4 Socket 6 235 pins 486 DX4 Socket 4 273 pins Pentium 60 en 66MHz Socket 5 320 pins Pentium 75 t/m 200MHz Socket 7 321 pins Pentium, AMD K6/K6-2/K6-3, Cyrix M1/M2 Socket 8 387 pins Pentium Pro 150 - 200MHz Slot 1 242 pins PII, PIII en Celeron Slot 2 330 pins PII Xeon en P III Xeon Socket 370 370 pins PIII, Celeron, Cyrix III Socket 423/478 423/478 pins Pentium4 Socket 603 603 pins Pentium4 Xeon PAC418 418 pins Intel Itanium PAC611 611 pins Intel Itanium 2 AMD processors Slot A 242 pins Athlon Socket A 453 pins Athlon, Athlon XP, Athlon MP and Duron Socket 754 754 pins AMD Athlon 64 Socket 940 940 pins AMD Opteron Conclusion: You can not upgrade beacuse Armada M700 has a pentium III processor with 370 pins. So the Socket 478 pinned pentium is not suitable. Advise: Try to exchange it with a new laptop or buy a used laptop for suitabl configuration

Are all P4 478pin cpu's compatible with the P4mm2 motherboard?


Just in case your pins are only bent you can straighten them out as long as you are careful. Take a mechanical pencil without lead (.5 works ok but .7 may be easier to use) and ground it by touching it to your power supply. Then work the CPU pin slowly into the pencil and slowly bend the pin up. If you?re patient and careful you can usually straighten out any pins that have been bent. You didn?t stat which version motherboard you had. On the P4VMM2 (V1.3) motherboard the manual states that the motherboard will automatically determine the CPU clock and system buss frequency and makes the appropriate changes. The manuals only references a front-side buss limitation of 400 MHz, however, a FAQ from the manufactures support site says the V1.x motherboard?s CPU is limited as follows: - Pentium 4 400Mhz FSB (256K/512K L2 cache) CPU ? 2.6GHz - Celeron 400Mhz FSB (128K L2 cache) CPU ? 2.6GHz I would stick with the FAQ recommendations if you have to purchase a new processor, that or contact the support line to verify. Make sure you point out the FAQ on their site since they will probably just refer you to the manuals specs.
