DELL Optiplex 9020 SFF High Performance Desktop Computer, Intel Core i7-4790 up to 4.0GHz, 16GB RAM, 480GB SSD, Windows 10 Pro, USB WiFi Adapter, (Renewed)’]

got 2 units with i7 4770 processors not i7 4790 but they backed up purchase
They sent me i7 4790s and over phone walked me thru downloading to both units latest Dell bios and Management Engine components Installer as well… 4790 came up with 4Ghz speed from 3.6G… and temp is stable at average 40Call seems good so ordered a 3rd Dell Optiplex 9020 from them, should be here next week per their tech support…Note: need to go into Bios with F2 and set enable performance to Boost on and multi speed on… and in Windows Power Options set to High Performance, at hi and low to100%… hope that may help someone else using i7 to get processors running at multiplier of 40.. Note the i7 4770 will boost to multiplier of 39, so is about 3.9G but temp is good 20C higher average, ie about 50-60c and hi temp limits speed down under loads… so using the 4790 I think is better choice.. runs and is stable under heavy loads highest temps I observed were in low 50C, I do heavy work with videos and need lowest cost per computer with at least 4G speeds, all 4 cores running, with 2 hyper threads each core… Will give update later if can do so, am 80 years old and still going strong, thankfully, and it is because of God’s help I am sure..11/3/2020 updatehave ordered and received a 3rd unit… all are working well at 4Ghz in my applications… need to be aware of settup noted above to see and set up correctly to work well at 4Ghz, and redu the silicon to keep heat down if that is an issue… Very satisfied customer!!

Impressive *
First off, let me say that before I even got started I opened the computer to see how many RAM slots there were. There were 4 and 2 were empty. I had 2 DDR3 8gig sticks from a broken computer that I then added to this machine, so unfortunately I can’t speak for the performance straight out of the box. Hence the “*” in the title and the 4 star rating. After starting this computer up, I am really impressed! It is really fast and has no trouble streaming from my Xbox one in the bedroom. I played Red Dead Redemption 2 for hours without any problems.

A tale of two vendors
I first ordered the Dell 9020 from a vendor that was not very good. Not my choice. I just went to the main Amazon page and clicked on Add to My Cart. That computer started to crash frequently; at one point crashing every 10 minutes. I talked to the service department, and they suggested two fixes: download a new OS and test one RAM card at a time. Neither worked, so I returned the computer.I then ordered the Dell 9020 from Blair Technology. What a change! Better packaged, better instructions, cleaner, and the computer worked just fine. The DVD drive was not operational, but I called Blair and they sent another drive. No fuss. That drive is now working fine.If you are going to order re-furbished, I suggest that you look into the vendor carefully. Look at their return policy and guarantees. Look up the company on the internet. I should have done that with the first vendor. The price of the Blair version was about $10 more, but avoiding the many hours that I spent testing and re-testing the first computer is worth much more than $10.I am now a happy owner of a Dell 9020.

Great Value
The computer is very fast and has lots of options. I had an issue with Microsoft updates and I called the seller’s Customer Support number. The Customer Service tech was very patient and knowledgeable in trying to help me with my issue. It was no fault of the computer but they were happy to help me work through a solution. I would not hesitate to purchase another computer from this company.

Fast but does not have the capability to upgrade to Windows 11 and soon Microsoft will not be updating windows 10

Best value, best service, best seller.

Better price better quality
