Motherboard Z87PRO Clock reset and the NGX

[Michael Moe 496]

hmm, For a while i have replaced my CR2032 5 or 6 times during my 5-10 minutes flying time and for now i have only seen this issue with the NGX 737-600?

 

This has been a rutine for a while

 

Any body else ?

Can you provide more detail? I'm not sure I follow what you mean by having replaced CR2032 5 or 6 times during 10 minutes of fly. I can only assume you are referring to the CMOS battery. Are you saying you pulled out the battery while the computer was on? What issues are you having?

If the BIOS/UEFI clock freezes up (which is a known issue with a range of recent Asus boards right now) it definitely will have adverse effects on our products. We use the BIOS's high precision clock to keep track of a lot of different things in our systems simulations. You'll see very odd things like fuel suddenly disappearing etc.

There is no way for a problem like this to only affect one NGX variant - they're all the same gauge dll.

When I start having issues with the clock, it is typically do to a bad OC. A clear CMOS resetting the BIOS fixes it. Are you OCing? Also, there has been quiet a few BIOS updates released. Are you up to date.

The UEFI BIOS clock freeze problem is a known issue with several Asus Motherboards at the moment, mostly their high performance "ROG" boards. Those affected by this remain hopeful that ASUS will find a solution but so far, they appear confused and over on their forum, are appealing to affected owners based in the USA to volunteer to send them boards to help them troubleshoot. I too am affected. A procedure published on the rog.asus website forum provides a quick fix to restart the clock, battery removal not being necessary. However the problem will randomly resurface, usually about two weeks later. Unfortunately the latest BIOS update fails to correct the issue, just gets the clock running for another two weeks or so.

 

Typical symptoms in the NGX if this happens in flight are a Master Caution Warning, total failure of AutoPilot (LNAV, VNAV, HDG SEL Auto Throttle etc) and pressurization failure. This with simulated failures set to OFF in the PMDG FMS options menu. One can continue flying by hand as the sim does not crash but it is frustrating.
