Hello
If you have built your own machine or upgraded the ram in a current machine, you should check your memory speed.
Often, people will install high end, high speed memory not knowing that it has to be configured in your computer. The result is that the computer will run at a noticeably slower speed and you never know it. With software like MSFS, this can result in lower performance.
For instance, say you have an AMD chip and installed DDR4 3600 DRAM. The computer will not run at DDR 3600 and will default to a much lower setting such as DDR 2100. Checking is easy.
Enter task manager by right clicking the windows button on the bottom left of your screen and selecting Task Manager. Click the performance Tab, then click on the memory box on the left. on the right side look at Speed. It should match your memory speed.
If the speed number is lower than you expect, google how to set the profile for your motherboard. Common names used for the memory profile are XMP, X.M.P, XMS, X.M.S, and D.O.C.P.
It’s easy to do but be sure to follow directions, especially if you are not used to working in the BIOS. Do not change anything you are not familiar with.
After making the change, exit/save and the machine will re-boot. If your setting had been wrong, you will see a speed increase right away during windows boot.
Sometimes the default profile does not work and the machine will reboot again with the default settings. In these cases you have to enter the frequency, voltage, and timing settings manually. More google is needed for this. In Most cases though, the setting is all that is needed.
It should be noted that doing this is not always beneficial. Sometimes the CPU can become too hot, and it’s better to have higher clock speed than memory speed.
In addition, higher ram clocks stability are handled by ram voltage, vccsa voltage and vccio voltage.
For example: with an i9 9900k 5.0ghz and 32gb ddr4 4266mhz i have stability with 1.25v vcore, 1.5v ram voltage, and both 1.35v in vccsa and vccio. Below those values msfs CTD.
I could swear I had my setup sorted out correctly. Must have lost it during a BIOS update.
RAM speed changed from 2133 to 3000. Thanks for the free system upgrade
Wow, I checked and I was coming in at 2100. I followed your instructions and now I am at what my memory is supposed to be, 3200. Thanks for the information.
I just upgraded my ram yesterday. I saw it was not running at 3200 and know I need to change it. First things first, writing an image of my 256gb SSD so I can upgrade to a 1TB SSD.
Even at the lower speed, with 32gb instead of 16gb the system booted faster.
I have an i9-10900K, 32GB (4 x 8GB) 4000mhz Corsair Vengeance, Radeon 5600XT, but if I turn on the XMP, MSFS crashes randomly… sometimes I can make a 4hrs flight, while sometimes I can’t make a 4mins. flight, because it crashes. If I keep the XMP off, never crashes. Any suggestions?
Yes, when this happens you typically have to increase the memory voltage a tad. Google xmp crashing and you should find how to change the setting for your bios.
