PMDG MD-11 Desktop Crashes ---SOLVED

Recommended Posts

I posted a problem in the PMDG forum concerning the new MD-11. The problem concerned OOM and crashes to the desktop. The response was that I should enable the 3Gb switch which might solve the problem.There are now a number of people who are having the same problem. It would also appear that PMDG developed and optimized the aircraft using XP - that at least is the impression they give.The problem I have is Vista and FSX. Reading about use of the 3Gb switch I see a great deal of doubt on the part of users that this switch will solve OOM problems while using FSX - at least under Vista 32-bit.Now, my system is a high-end dual-core, 4Gb RAM system using a 8800 Ultra graphics card. As I said above, my OS is Vista 32-bit. PMDG stopped responding to the thread I posted so I don't know what (if anything) they might do to address this problem.Note: I run their B744 under Vista without problems.I'm not posting this message to cause users to not purchase the new MD-11. It is a fantastic product. But before you plunk down 80USD you might want to wait until there is a response from PMDG about this issue - other than use the 3Gb switch under Vista. Note: In my case I'm out more than 200USD as I also purchased the training materials. Right now I can't use the aircraft.Request this posting to be bumped until we get a response from PMDG.Frank

The fact that you have 4gb doesn't change anything.We are talking about virtual adress space here not physical RAM.So don't wait and do it,I am sure you won't regret it.Yves

Well, I didn't think it was possible but after I set the 3Gb switch I was able to access the aircraft without FSX crashing to the desktop. I haven't set up a proper flight yet but the system was stable while the aircraft was loaded.So, on to the learning curve for MD-11 systems.Thanks for your response.Frank

Frank for the record I can report that I am running the MD-11 under Vista 64 with zero problems. I've flown the MD-11 in the sim probably 6 hours so far.Since our hardware is so similar, one logical conclusion to draw would seem to indicate that it is a Vista 32 issue or some sort. ??I don't quite understand the thread title--which says the issue was solved--and yet I didn't read anything in this thread that said you solved it. ??RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT

>$120 for the MANUALS????? And what's so shocking???? Actually for 1400+ pages worth of documentation on quality paper, all the hard resin binders, color tabs, rings it sounds outright cheap. When I once attempted to purchase Beechcraft Hawker 800XP (biz jet) full set of documentation it was around $1300 over 10 years ago. These are not comics books you can get for $2.95.Michael J.http://img142.imageshack.us/img142/9320/apollo17vf7.jpg

If I'm going to buy real manuals, I will be sitting in a real plane. Last I knew this was a 'sim', and thats stretching it, to each his own I guess. :-)

Ah, ok I see. I didn't think just loading the aircraft successfully was "solved", I thought him completing a 1-2-3 hour flight would be "solved". :)As an aside, I know Frank Bass runs such a great AI environment, however the cost of that is memory usage. Perhaps this contributed to the crashes. ??RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT

The size of my AI environment may have contributed to the problem but I run the PMDG B744 with the same environment. I didn't change anything before or after enabling the 3Gb switch.For those who are having trouble finding the instructions for enabling the 3Gb switch - here you are:Enabling 3GB switch on Windows Vista

>Since our hardware is so similar, one logical conclusion to>draw would seem to indicate that it is a Vista 32 issue or>some sort. ??That seems to be the "general" consenus from a lot of folks I have spoken with. The OOM issue does not saeem to really affect 64-bit users. Unfortunately, I heard 64-bit brings with it some other issues that 32-bit users do not have to deal with. Not being a 64-bit user myself, I am unable to really elaborate on what those issues may be, but if I remember correctly, I think there are some issues with NAT and a few other things (I could be wrong here).I suspect the PMDG crew may have stopped responding because there is nothing on their end that they can do about it. It is not the fault of their aircraft so they really can't help out other than to recommend that one decrease simulator settings that increase the burden on virtual address space.

Heh, for a second I thought you were joking. But you're not. Oh my. Are they seriously charging an additional fee for the manuals?

Actually I skimmed the thread to see the state of bugs in the add-on, but I did notice your post about how a manual on fine quality paper is worth 120 bucks. So my question was sincere. They are charging extra for the manual? Whoa.And honestly, I thought you were being sarcastic about how the manual was worth it. I just sounded a bit absurd the way you phrased it.
