So I got a cheap old dell optiplex gx280 sdt. It has an old single core processor in it. Its a celeron series 2.5ghz. I figured I could upgrade the CPU to something a little more modern. I'm finding conflicting results when trying to find my answer. I found the motherboard compatible with the case and it says you can use up to a pentium-D in it. http://www.amazon.co...SDT Motherboard. But when I looked other places people are saying it only supports up to pentium 4 processors with hyperthread. I wanted to use this processor because its fast and cheap and acording to this amazon link above it should be compatible. http://www.amazon.co...0?ie=UTF8&psc=1. If i can't use this CPU is this pentium 4 compatible? http://www.amazon.co..._?ie=UTF8&psc=1. I would love to be able to install the pentium-D in his computer. Its his first computer I'm fixing up for him for christmas. Any help is appreciated.

 

Best regards- Tim.

:welcome:   tim.h1995,

 

Trust the information from Dell above all else and they state P4 and Celeron D at the spec sheet here

 

Run the Intel® Processor Identification Utility Download for Windows tool here make a note of the PCG number for the processor (Platform Compatibility Guide)  04A is one such example, any potential CPU must have the same PCG code else it is not compatible with the MB and will not function.

So I would run this program on the gx280 to find the cpu pcg and then what do I do with that after I get it? Compair it to another cpu see if it matches? Also on a new cpu how would I find the PCG for it?

Correct and you should not purchase any new or used CPU that does not clearly state the PCG, a list of socket 775 CPUs here, this will give you an idea of what to look for once you have your full CPU details, you can also post them here and we will see what we can find.

Thank you very much. When I get back from church in a few hours I'll post my CPU details up if I'm still having trouble figuring it out. Once again thank you for your time and advice.

So I think I might have figured it out. I noticed a correlation between OEM and box numbers compared to info I found on the dell website about the original configuration part numbers (PROCESSOR, 80547, CELERON PRESCOTT DESKTOP SOCKET T, 325, E0). The string 80547 kept appearing in only a few select processors so if I'm correct this is his processor http://cpu-data.info...256&gr=-1&lng=1 and the Pentium 4 that is compatible is this one http://cpu-data.info...1MN&gr=-1&lng=1. I really hope I got this I spent hours looking at all the information I could and trying to find some correlation.

I found what I believe to be P8605 Prescott P4 Kit, 560, 3.60G, 800FSB, 1MB, Socket-T, E http://www.amazon.co...l pentium 4 560 http://cpu-data.info...41M&gr=-1&lng=1

 

I also found a M8965 Prescott P4 Kit, 570, 3.80G, 800FSB, 1MB, Socket-T, E0 http://cpu-data.info...21M&gr=-1&lng=1 the only thing is idk how easy it would be to return just because of the site that has it available http://www.txmicro.c...82U-p-4971.html or I found one on ebay http://www.ebay.com/...=item35de4272cd

The 570 from China after reading the description I would say  :no: and opt for the Intel Pentium 4 560 3.6 GHz processor ( BX80547PG3600E ) from Eagle_eye Electronics here

 

Benchmarks for the present and potential CPU here

 

Full CPU specs here and here you will note that the CPU codes change when they are "boxed" as opposed to OEM/Tray processors, the CPUs are the same but Intel does not provide the warranty for OEM CPUs the merchant that sells the processor on does, Intel explanation here

 

Be sure that you are 100% certain that any potential CPU that you may purchase is the correct one and that it comes fully working  from a reputable merchant.

 

Please disregard any other product, service or suggestions from any of the above links.

So when it says it draws 115 watts of power is that necessary to have? I fear that I may tax the PSU too much. I have a graphics card 1 HDD 1 DVD drive and the new CPU (when it comes in) on I believe 220 watt PSU.

An explanation courtesy of CPU World;

 

Thermal Design Power (TDP)

The Thermal Design Power (TDP) is the average maximum power a processor can dissipate while running commercially available software. TDP is primarily used as a guideline for manufacturers of thermal solutions (heatsinks/fans, etc) which tells them how much heat their solution should dissipate. TDP is not the maximum power the CPU may generate - there may be periods of time when the CPU dissipates more power than designed, in which case either the CPU temperature will rise closer to the maximum, or special CPU circuitry will activate and add idle cycles or reduce CPU frequency with the intent of reducing the amount of generated power.

TDP is usually 20% - 30% lower than the CPU maximum power dissipation.
