FSX: OOM even with high specs?

[marcrg24]

Hi all.

i'm trying to get my fsx to run with three monitors. it can run two perfectly, but as soon as i undock a window and put it onto my third monitor, the game crashes and gives me an out of memory error. i have ran tests, my Ram usage is only 5GB out of 8gb when i add the third screen and then it crashes. i did notice that my cpu usage flew up to 100% just as it crashes. i have a theory. i am running windows 7 64bit and i keep on getting a pop up message saying i have unsupported hardware, meaning that my cpu is not made for windows 7. could this be my problem? on my old pc it could run three monitors just fine but was too laggy for me so i built my own pc. i know for sure that specs aren't an issue (graphics settings aren't even at highest) but i'm guessing it's my OS
my specs:
i5 7600k cpu
asus dual gtx 1070 8gb gpu
8gb ddr4 ram
asus z270-k motherboard
8502 fully modular psu
1tb of hdd

can anyone help me with this??
any help would be much appreciated
many thanks
kind regards

i believe windows 7 only supports upto the 6th gen intels (6xxx)? which explains the windows warning.
If youre using 100% of the cpu, i believe there is a reference to hyperthreading issues floating around in the news feed somewhere, try going into bios and turning it off? if it works, then you know its that issue.
check that your swapfile is large enough for graphics dumps! graphics cards use their ram, then your system ram, then start dumping to swapfile. I know a lot of people try turning off or severely restricting the swapfile to force system ram use, but it can cause lag/crash issues.

I have an i5 and hyper threading isn't supported for my cpu, what shall I do??

i read somewhere that super sampling can cause issues when you move to 3 screens, try turning it off?

cannot suggest anything else 🙁 sorry

I'm currently trying to edit my windows registry to see if that would work, idk why it would but oh well. I'll try your suggestion now and if not thanks for your idea anyway, you've been really helpful

Hey Marc, I've been flying FSX Gold and now SE since it came out in the beginning. I think the OOM issue you are having is just the 32 bit limitation inherent to FSX. Despite having a 64 bit processor and OS, FSX is a 32 bit application which can only utilize roughly 4GB of memory. If you have scenery addons, aircraft (like the PMDG 737) along with sliders cranked way up, OOM's will result. FSX is a never ending game of give and take to satisfy our need for the eye candy, performance, and what the program is actually capable of. I use an old E4400 C2D to run mine and it's now time for an upgrade (looking at Ryzen) when this happens I will likely ditch FSX altogether and go to either Xplane 11 or Prepar3d V4. Both of which do not suffer from the limitations of my old friend, FSX. (They will also utilize multiple cores much better as well).

Chris.

Hi Chris.
Thanks for your response
I actually found a fix myself literally a couple of days ago by using nvidias surround setting in the drivers and I managed to get it all working perfectly, and I can tell you it looks amazing!

I hope your upgrade goes well
