Optiplex 7020 MT, CPU upgrade?

Jump to solution

 Hello, 

I have been given a Dell Optiplex 7020 Mini Tower free of charge and was wondering if there's any way I could possibly upgrade the i3 processor to an i5/i7. I am planning on using this PC for some gaming this Summer (I'm not talking massive gaming just something that can run a vary of games that require i5 processors), I do have a graphics card etc to go with it and able to get more RAM. I do have money to spend If I did need to buy parts. I have since have been using a Macbook Pro and have missed gaming. I am aware this type of PC is mainly used for office work etc but just wanted to know if it was possible and what i'd need to go out and buy to make it run better.

Here are the specs:

Windows 7 Professional

Dell Optiplex 7020 Mini Tower

Processor: Intel(R) Core(TM) i3-4150 CPU @ 3.50GHz

RAM: 4.00 GB

64 -bit operating system

I have attached photos of the motherboard:35358097_2357023900990645_2314314613161721856_n.jpg35628606_2357023927657309_2901145688555388928_n.jpg

Thank you.

Hi tiger_pearl,

The 7020 has an Intel Q87 Express Chipset which supports the following CPUs:

http://www.cpu-upgrade.com/mb-Intel_(chipsets)/Q87.html

The highest specification of CPU that Dell validated with the 7020 was the i7-4790 so anything from the above list should be ok. One thing to check though, is the heatsink. There are two versions, one rated at 65W and one at 95W. If you are using one of the higher rated CPUs you will need the 95W version. I can't tell from the photos which version you have but there should be a label on it with the part number. G8CNY is the 95W version, whilst X3JDD is the part number of the 65W version.

If you are going to upgrade the CPU, make sure that the BIOS is up to date beforehand.

Thank you so much for replying so quickly back to me, I am planning to go for one of the i7's preferably the intel core i7-4770k or any of the other 4770's. I was just wondering what type of heat sink should i buy, is any type of 95W heat sink okay? As you can tell i'm extremely new to this and i'm going to start to need talking graphics cards soon as I still don't own one

 

Thanks

The heatsink might have to be the Dell one, I'm not sure if a 3rd party one would fit properly. 

As far as graphics cards go, the AMD Radeon R5 240 and AMD Radeon R7 250 were the only two models that shipped with the 7020. However, you'll be able to get something newer and better than them but I'm not really the best person to advise on that.

Thanks

Thank you for getting back so quickly, sorry for the late reply, I sorted out the right heatsink 95W and bought an i7-4790 and just put it all together today. When I tried to turn on the computer, the power button was flashing orange, taking a few seconds in between each few flashes. 

Thanks a lot

Sorry to hear you're having issues. Does the system still work if you put the old CPU back in? 

The power button should be flashing in sequence to indicate the possible cause of the error:

What is the code the you are seeing?

If you could let me know, thanks.

Hello I had the same issue upgrading Optiplex 3060 MFF from I5 to 8700T. Amber light appears. Should I have to wait unitl new processor installs? Is there a settled time it would take until computer starts?

Thank you

Alasdair I have a 7020 sff running a core i3, 4th gen. What problems would I face upgrading to the core i7. The 7020 did have an i7 variant, were the motherboards the same?

4770K would require the Optional 365W power supply.

Dell OPTIPLEX XE2 9020 7020 3020

Precision T1700 T20

DPN 7VK45 T1M43

365W

This is a Proprietary 8 Pin instead of 24 pin Power supply.

Or you get a MODDIY Adapter and you can use an EVGA 700B1 power supply.

Theres even a guy who modified a power supply to work.

I have the ability to do this but I'm not willing to invest the time and effort.

https://raphtec.wordpress.com/projects/dell-poweredge-t20-atx-power-supply-adapter/


MODDIY CAB359 cable or equivalent.

This is not however supported by Dell.

Someone has already tried this and it works.

http://en.community.dell.com/support-forums/desktop/f/3515/p/19986195/21009213

 

 

EVGA Super nova 700B1 or 750B1 works fine.
