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.

What is NVram. I am asking because I have built 2 computers and have never heard this term before.

The 520 will error out with CPU's faster than 2.8ghz and say Incompatable processor. The GX620 does not have this issue.
You do need to update the bios however on the 620.

I tried to reset the CMOS as suggested in the manual - it didn't help.I still get the "Incompatible CPU detected" and @Press F1 to continue". Although after pressing F1 all seems to work fine.
My system: OptiPlex 520, Pentium D 820, BIOS v. A11

The 520 doesnt support pentium D 820 or 915 without the performance heatsink and fan. This is not going to change.

Thank you for your reply,
Does motherboard able to recognizance the type of fan and heatsink?
What do you think will be the real life performance difference between Pentium D 820 and Celeron D 326? Is it worth to buy a new heatsink and fan?
