Hi,Seem to be getting random ctd within FSX - anybody else experienced 'The instruction at "0x7c809783" referenced memory at "0x19c36f0c". The memory could not be "written".'System is AMD 4800x2 running at 2.7Ghz, 2.00gb ram with 3070 set for virtual memory.Any ideas?CheersMike

As I recall, setting your own pagefile size in the performance settings vs setting it as "system managed" has caused problems w/i FS9 for many and has caused similar error messages. So I can see it happening in FSX too. I don't know why as many "experts" (geeks) recommend setting (tweaking) your own pagefile size rather than having the system manage it. In your case, I think 3070 is way too high for your VM setting and you may want to do some further tweaking.Best regards,Jim
