Acer Aspire 3 A315-21-95KF RAM not running at full speed

Hello all! I have an Acer Aspire 3 which I use as a general purpose laptop (web browsing, light gaming, remote desktop, etc.) and I have noticed recently that the ram speed is reported as running at a lower speed than it is rated for. The memory is in its factory configuration, with a single stick of ram in the machine, a 2400mhz 2gb Hynix stick of memory with 4gb more of Micron ram soldered to the board for a total of 6gb of memory. I noticed recently in task manager that the ram was reported as running at 800mhz which seemed odd considering the stick was rated at 2400mhz. CPU Z reported the same information, so I decided to boot into a live linux USB and run "dmidecode --type 17"  to see if it was an issue with windows or something else. The ram speeds are reported at half since these are DDR (double data rate) dimms and I noticed that the speed is rated properly at 1200mhz (2400mhz actual speed), but for some reason there is a line called "configured memory speed" reading 800mhz (1600mhz is the real speed). This makes it seem like the ram is downclocked, however, I do not see any way to remedy this in the bios. I tried updating the bios as well since the laptop was running an older version but nothing changed. Is there anything that I can do to let the ram run at full speed or am I stuck with these lower ram speeds? Attached, you will find images from task manager and linux. Any help would be greatly appreciated. Thank you and kind regards

    Every new update from Windows 10 slows my Aspire E11 down to the level of a crippled snail. Now it's virtually unusable. Any suggestions before I bin it and get a Dell?

    Hello, has anyone found helpful or corrective information for this problem? I have a relatively new Aspire A315-21-62U1 experiencing the same problem. ddr4 ram stuck at 800mhz single channel. information obtained using cpuz & task manager. A little more information I also have an Aspire A317-32 which displays the ram information correctly at 2400mhz dual channel.
