Microsoft Excel 365 HUGE Memory Leak (50 GB RAM)
Same here...
My PC: AMD 5900X + 64GB + RTX3080Ti + 3440x1440x60Hz + Windows 10 Pro + Excel 365
If Excel works normally, it consumes 150-500MB of RAM. When it starts to lag, it consumes 40+GB. Usually the image freezes for a while and the only solution is to save the sheet and reopen Excel.
For me, the problem has been present at least from June 2022... I tried to solve the problem with a clean installation of Windows 10, then Windows 11 (no comment), drivers update or outdate... then I screamed at my PC and threatened him with a hammer... 😉
I noticed that there is no problem if:
- using Excel 2010
- using Excel 365 with "Hardware Acceleration" disabled
(this option has been removed some time ago - big "thanks" to Microsoft)
tomoam2 My Excel lockup is also on an AMD/nVidia laptop. Lenovo Legion 5 Pro, AMD 5800H + nVidia 3070.
Clifton_Cline Hi again (everybody),
Did you try this one:

"Assign application to specific GPU
[...]To make Outlook to use a specific graphics card (i.e. use a basic driver so it disables hardware acceleration).
Open Graphics Settings
Windows 11
Start> Settings> System> Display> (section) Related Settings> GraphicsWindows 10
Start> Settings> System> Display> (section) Multiple displays> Graphics settings
Select: Desktop app
Use the Browse button to add Outlook.exe (you can use Process Explorer to find the path if it is running or right click on the shortcut and go to properties.)
After you’ve added Outlook, select it from the list and press the Options button to select your GPU.
Use the Power Saving GPU: Microsoft Basic Render Driver to turn off hardware acceleration like you used to be able to do an easier way."
Excel 365 works much worse than the 2010 version, but maybe this method will speed it up until the patch is released?
I don't understand why Microsoft can't just restore the Disable Hardware Acceleration option?!
- Yes the registry is set to 1.
I had set the card to High Performance for the Excel app. It crashed again this morning so I'll try the Power Saving mode now.- I was at Power Saving Mode... no luck, at High Performance is a little better (little = little little better)...
