Re: Upgrade cpu optiplex gx 520

VlaDJ,

Thank you for using the Dell Community Forum.

The OptiPlex™ GX520 system supports the Intel® Pentium® 4 (Prescott) 5xx series and Pentium 4 Celeron® 3xx series processors.
Beginning March 17, 2006, the GX520 also supports the Intel Pentium D (Smithfield) 8xx series processors.

Re: Upgrade cpu optiplex gx 520

Maybe it will work if you upgrade the BIOS version.
 
Anyway, you will need a better heatsink. Your computer has a mainstream heatsink, and you need a performance heatsink.
 
Pentium 524, 531, 630, 640, 650 and all Celeron D: mainstream heatsink
Pentium 660, 670 and all Pentium D: performance heatsink (with heatpipes)

You may try to reset the nvram:

When I upgraded my GX620 from a 521 to 920 I did not need to change the heatsink. It doesn't overheat either.

Re: Upgrade cpu optiplex gx 520

Hydralisk00222,
 
I'm glad to know that it worked fine because I have an Optiplex GX620 mini-tower with a Pentium 4 630 (3.0Ghz FSB 800Mhz 2Mb L2).
 
Btw...
 
1. Is your GX620 a mini-tower?
 
2. Does your GX620 have a mainstream heatsink (like the picture below) or a performance heatsink (with a internal heatpipe)?
 
 
3. Did you get a "incompatible processor" warning?
 
Thanks.

Re: Upgrade cpu optiplex gx 520

I tried installing a P4 531 into my GX520 which previously was working fine with a P4 521. It gave me a "processor not supported" message which doesn't make since to me since they are pretty much the same CPU with a 200 MHz speed difference. Any suggestions on how to get it to accept the new CPU?

Re: Upgrade cpu optiplex gx 520

Hi I have a Dell GX520 sff...My cpu was a 2.6GHZ....I have now upgraded to a Intel Pentium P4 661 Processor 3.60GHz 800FSB cpu / Part Number HH80552PG1042M CPU Speed 3.6GHz Package Type LGA775 L2 Cache 2 MB I updated the system bios. Then i have the same problem. My pc works fine with it,except on start-up it askes to use F1 or F2 keys because of imcompatability...but after pressing F1 it starts into windows and works fine. I have tryed reseting the NVram , but this seems to make no difference. Any suggestions please ??
