CPU compatible with Optiplex 390

Yes, I found that too, but I was wondering if i7 will also work if it is a Sandy Bridge CPU, or Dell bios is so picky that I can only put specific CPU's.

Hi Chan.Y.Park,

The supported processors, according to the tech specs, are 

Intel® Core™ i5 Quad Core; Intel® Core™ i3 Dual Core; Intel® Pentium® Dual Core; Intel® Celeron® Dual Core

But what about Intel G2020? I tryed and is not working. On the internet I found that it must support also ivybridge.

Hi Catalin Popa,

That processor is not listed by Intel as compatible with the H61 chipset.

This is very strange because I have another computer with a gigabyte motherboard (GA-H61MA-D3V) and this one support G2020. It is not the same chipset?

What if you put an Intel core i3 Dual core and all you can see is two cpu processors and not 4 ?

I have INTEL XEON E5-2670 2.6GHZ 20MB CACHE CPU do you know if it will work with Dell OptiPlex 390?

Thank you for your help . Paul.

Unfortunately not.

@kevinmasb check your bios settings for hyper threading , (i3 has 2 Cores x 2 threads = 4vCore)

@soroka69 is working with E3-1240 Sandy Bridge (v1) (4Cx4Ht = 8vC at 3.3Ghz)

Question: What is the best processor supported by this system?

No answers really to this question yet? Where is the CPU support list?! Cmon! Let's get it done!

Where's Speedstep when you need him? ;)

To the guy who asked about putting in the i3 and only seeing two cores:

Is Hyper Threading turned on in the BIOS?

E5-2670  FCLGA2011 is a non starter. Socket is not the only requirement. Onboard voltage regulators also count. Ivy bridge is the last cpu on the LGA 1155 socket. Processors for LGA 1155 and LGA 1156 sockets are not compatible with each other since they have different socket notches. This is also why Xeons don't work.

The Spec doesn't mention ANY I7 working.

The 2130 says 2 cores 4 threads FC LGA 1155 

Definitely DOES NOT SAY Ivy Bridge 22 nm

Core i7-3770 SR0PK 3.4 GHz Quad-Core 

Socket LGA1155 CPU will work.

So sandy Bridge is likely a non starter.
