The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the Dell OptiPlex 3020 SFF doesn't have one. This is not a problem if there is on-board DisplayPort. Based on the multitasking test, the desktop guaranteed smooth processing regardless of the large number of operations running simultaneously.I also performed Futuremark’s PCMark 8 benchmark on my review unit. The Dell OptiPlex 3020 SFF comes with eight USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. Unfortunately, this model doesn't come with a USB 3.1 port. If you need a faster connection for your peripherals, like external Solid State Drive, you will need to choose another model. Video ports
See Dell Knowledge Base article How to Diagnose and Resolve Common Memory Issues on a Dell Desktop Computer.Thanks for this, I followed your instructions and am now writing this from my multi-boot W10/MXLinux/ISO boot etc….they all work! Also, the Dell Optiplex 3020 supports some dedicated graphics cards as well. You can get the desktop with an AMD RADEON HD 7570 GPU which has a dedicated VRAM of 1 GB. If you can troubleshoot, narrow down the issue by removing the memory modules one by one to determine which module failed. Consequently, the performance of the Optiplex 3020 is decent, especially for a 4 thgeneration computer. Therefore, I’ll rate the Dell Optiplex 3020 a seven for its processor performance. Dell Optiplex 3020 Memory (RAM) Performance Review
If you can troubleshoot, narrow down the issue by removing the memory modules one by one on to determine which module failed. You can alsocombineconfigurations to validate the appropriate combination.Due to its budget-friendly price, the Optiplex 3020 is an efficient entry-level computer for small and medium-sized businesses. Having said that, let’s proceed to the main discussion. Dell Optiplex 3020 Design, Dimension & Weight Review Below the DisplayPort is a blue section that houses the VGA connector. Next, below the VGA connector, there are 3 rows of USB ports.

Dell OptiPlex computers have a long history of integrated diagnostic indicators that provide important insight when a computer failsthe Power On Self-Test ( POST). These indicators can be audible beeps, power buttons that display different states and colors, specific diagnosticLEDs, or a combination ofthese.To prove its multitasking ability, my review unit performed multiple tasks simultaneously. The multiple tasks running on the desktop included web browsing, video conferencing, and working on several spreadsheets. USFF chassis was released separately and resembles the OptiPlex 9xx case and a maximum of 8 GB RAM due to 2 DIMM slots. Based on the outcome of the Crystaldiskmark test, the Dell Optiplex 3020 recorded a sequential read speed of 1251.21 MBps. Also, the desktop recorded a sequential write speed of 2302.58 MBps. Paul, I tried to do a fresh install but Windows setup would not install on my M.2 SSD drive as it was set as GPT. However, the desktop can play less graphics-intensive games at low settings. I played Minecraft at high settings and 1080p resolution, the game recorded a frame rate of 150 fps.
To upgrade the GPU of OptiPlex 7040 SFF, a low-power, low-profile graphics card must be used. Currently, the most reasonable GPU option is AMD's Radeon RX 6400 low profile. Dell offers the Optiplex 3020 in three innovative form factors. The availability of several form factors enables users to choose the size that perfectly suits their workspace. Furthermore, the Dell Optiplex 3020 has an optical disc drive. Finally, the desktop has an impressive number of USB ports that you can use to connect external storage devices.
If you can troubleshoot, narrow down the issue by reseating the PCI cards, and removing them one by one to determine which card failed. Additionally, the Core i5 processor has a base frequency of 3.20 GHz and a boost frequency of 3.60 GHz. I put my test model to a Geekbench 3 benchmark to determine its processor performance. If the fault continues, remove any graphics cards and retest with a working monitor and video cable. I’m still working through the list in a hope that I find a suitable solution but one post (Alvin03/02/2022) I couldn’t work out, he installed Win 10 20H2 (over the previously installed Win 10 21H2). What is Win 10 20H2, a version of windows, if so is this worth a try? In addition to the various types of diagnostics LEDs, there are several audible beep codes across all the models of these computers.
