Well, since fitting that 12VHPWR cable, my GPU seems happy for now Dave. No further shutdowns since my last post here at any rate. Of course, that doesn't help you much, especially since you've replaced your connector. Sorry I can't offer anything more encouraging. Thanks, Nick

Ah, glad to hear you seem to have found the cause too Dave. Your 4080 will be 2-3 cm's wider than my 4070 I believe, so can quite see how the power connecter could impinge on the side panel. I wonder if a few dabs of dielectric grease would help in your case too?

Hello Dave, Just dropped in to find out how you're faring with this issue, and with a small update from my end, and realised I overlooked your last post. Sorry about that. No, it's a Gigabyte MB I've got, as well as the GPU. For me the issue seemed to be increasing in frequency, and I was also able to reproduce it fairly consistent by stress testing the GPU. Typically after just a few minutes at 100% utilization (just over 200 watts in my case) the dreaded black screen with fans going to max would result. I experimented with undervolting too, but this didn't resolve the issue. Being a bit reluctant to go through the hassle of a RTM and not being too confident it would even resolve the situation, I decided to replace the power cable instead. This was based on some comments I read somewhere and 'only' set me back £18 (though I really thing something like this should have been included with the GPU itself). Although I'm hesitant to jinx things, this does seem to have fixed the issue. I've been able to run the GPU at max for over and hour on a few occasions and it's remained stable. For info, this is the replacement cable I purchased and it's a much neater solution than the NVIDIA adaptor going into for my PSU cable. 12VHPWR Cable | 600W PCIe 5.0 Power Adapter Cable (corsair.com) When the cable arrived, the box also contained a little sachet of dielectric grease which may also have helped. Anyway, will let you know if I'm celebrating too soon. I'll also stick with the undervolt for now too, at it reduces power usage by around 30-40W and seems pretty stable. Cheers, Nick

Unfortunately I haven't been able to diagnose or resolve the issue yet @regis9. It's very sporadic, sometimes the PC will run GPU-intensive software like MSFS happily all day and on other days, the lockup will occur at least once in the space of an hour. I had a little hunch it had something to do with the fan controller side of the software rather than a hardware fault (in general, I'd say Gigabyte's software is pretty diabolical) but I've been away from home a fair bit with the day job recently, so this has limited the amount of time I've been able to spend tinkering with my sim PC. Hoping I'll have a bit more time at the end of the month to investigate properly.

Thanks for confirming Dave. Yes, I've found a few other discussion relating to this issue such as this one. New RTX 4070 Ti will stop displaying and go full fan speed out of nowhere. HELP : r/gigabyte (reddit.com) I haven't contacted support yet, but an RMA may be on the card. However, I am going to experiment with undervolting the card beforehand.

Hello Dave, I'm having exactly the same issue with my 4070 GPU: fans run up to full speed and the video display is lost forcing a hard restart. (Resetting the GPU with Ctrl + Shift + Start + B doesn't work.) No apparent pattern as to when it happens, sometimes when the card isn't under load, although on other occasions it will happen when running MSFS or other games. Anyway, as you'll have discovered, it's rather annoying! Mine is a Gigagbyte GeForce RTX 4070 GAMING OC 12GB which was purchased around 6 months ago. I'm curious if Gigabyte is the manufacturer in your case too? For what it's worth, I've tried replugging/changing power cables, updating drivers, and most recently updating the GPU bios. Not sure yet if the latter will make any difference but we'll see. Cheers, Nick

Just a little note to let everyone know that we've just released the v1.2 update for the Comanche. 🙂 To install version 1.2, please click the "Comanche Check For Updates MSFS" shortcut in the "A2A Simulations" folder in the Windows start menu. Thanks Nick - A2A Simulations

Yes, just to confirm that we are aware of a bug where a sudden, huge spike in engine torque can, very, very, very occasionally flip the entire plane the plane in the air when using the starter or when towing (the prop is actually rotated a bit when you attach the tow bar, so it doesn't make contact with it). This has resulted in one or two funny moments on livestreams, and we would like to particularly apologise to any VR simmers who have been traumatized as a result. 😁 It's been hard to reproduce, but should be fixed with the first Comanche update which we'll get out as soon as we can. Thanks, Nick - A2A Simulations

If I click the link in iTunes, it just takes me back to the "iTunes Preview" browser page with the "this app is only available on the App Store for iOS devices" message. I guess it knows I'm trying to download it on a PC or Mac which won't run the software. Perhaps the app store download restrictions have changed recently? Nick

Are you accessing iTunes via an iPad Jean-Luc? I can't seem to download the app using iTunes on Windows or even on my MacBook. Nick

Hmm! "This app is only available on the App Store for iOS devices." How very - Appley! Nick

Thanks Jean-Luc, I'll give that suggestion a try. Bert - thanks for your post too! Regards, Nick

I understand from this topic that one of the advantages of the RXP GNS products is that the aviation database ("worldwide.bin" file) can be updated with the corresponding file from the Garmin GTN trainer (which will just need to be renamed). However, a recent change to the GTN trainer means that these files are no longer compatible (i.e. they can't simply be interchanged any more) and I'm unable to find any download links for previous versions of the GTN trainer. Therefore, I was just wondering if anyone still has a copy of the most recent version of the GTN trainer which does include a compatible aviation database? If so, would it be possible to share just the relevant *.bin file (something similar to "006-d0170-00.bin"), to avoid hosting a large download? Thanks, Nick P.S. I have already updated the GNS "bmap.bin" file with the corresponding file from the current GTN trainer.

Thomas, I can recommend Scan (though I haven't specifically bought Saitek stuff from them). They do the ProFlight rudder pedals for around 90 quid at the moment, and the yoke for about £116. However, looks like no stock until next month. Delivery would be about a tenner by the looks of it. Nick

Pe11e - just wanted to make you aware that leaving "high-resolution 3-D virtual cockpit" un-ticked will cause visual artefacts (enlarged LCD digits) on the radio stacks in the A2A Skyhawk, Cherokee and Skylane. It will also tend to cause some issues with cockpit lighting. Cheers, Nick
