Now elevated to level 2 tech support.

 

Typical level1 support. They ask seemingly silly questions to weed out the similarly silly users.

My level1 response was thankfully a bit more switched on and asked for screenshots and which driver versions it changed.

Given that this has happened before, it's not really a matter of Nvidia understanding the problem. It's getting the message through their army of support minions to the guy/girl who hits the compile button on the driver. In which case the "shotgun" approach of creating many support tickets and said person even accidentally seeing and fixing it increases our chances of getting this crap sorted.

To be honest, I REALLY hope AMD gets Polaris into laptops ASAP. Because Mobile G-Sync will be revealed to be the complete BS that it is, regular VESA Adaptive Sync.

 

Anyone else having problems with the latest nvidia drivers?
I'm not sure they are the cause of my issues but they were the latest changes I made to the PC.
Yesterday I got a BSOD while working on the PC like any other day. Upon rebooting I kept getting BSODs, it was stuck in a loop. Safe mode would not work nor would Windows recovery.
The BSOD error is always different, I must have seen 7 or 8 of them by now.
I can not boot into Windows in any way I have tried. I also tried a bootable USB drive with linux just to recover my data but to no avail...

Any guesses on what it can be? My spec is as follows (P771DM-G):
-6700K
-980m gtx (When I restarted after the first BSOD I was getting TONS of artefacts, but after restarting once more it has not happened again)
-2 x 8GB Kingston Hyper X 2400Mhz (ran memtest with no errors, tried one stick at a time and no change)
-Crucial MX200 m.2 SSD (boot drive with windows and software)
-WD Black 750GB 2.5'' HDD (storage)

I suspect it's something to do with the SSD but what might of caused it?

 

I would suspect a RAM issue (ruled out by you), CPU or motherboard. Also cannot rule out GPU as driver was the last thing updated and could have failed. I use driver version 362.00 as newer version does not support G-SYNC and some suggest that newer drivers can cause GPU failure.

 

I just ordered a 770-DM-G from Xotic, so I can't wait to try it out. Just a few quick questions while I (im)patiently wait:

1. I've seen others mention service manuals for Sager/Clevo laptops. Where can I get the service manual for my model? Google and forum search aren't turning up any links.
2. Can somewhat lay out the simple pro/con of UEFI vs. BIOS?
3. I have mine configured with a single NVMe 950 Pro and a 1 TB HDD. What's the best combination of settings and software (e.g., BIOS or UEFI? Sammy Magician?)? The manual gives conflicting info. First, it says that IRST does not support M.2 PCIe SSD's. Then several sentences later it says "note that if your system has a single PCIe M.2 SSD then a second reboot will not be required" when installing IRST. ????


Thanks!

 

From googling a bit I think nvidias 364.72 drivers are to blame

 

I have been advised to wait for the next driver update for this known bug :/ by the Level 2 tech support, who funnily enough was the same helpful tech support rep at Level 1.

So will wait and see.

 

So I dont think it's an SSD issue. Ive tried putting another HDD in and install windows 10 thru a usb drive but I get an immediate BSOD after post

 

Even with only one stick of ram and a new hdd with windows installed (from another pc) i get the immediate BSOD.
Now it's been pretty consistent with the error, it's always the PAGE FAULT IN NON PAGED AREA

Is my system bricked?

 

Google would suggest a RAM fault.

 

I ran memtest for hours with 0 errors!
There's various counts of bricking or issues with the new 364,72 drivers.
Some people say to boot into safe mode and fully remove the driver but I cant even hoot into recovery

 

Have you tried this :
Sign Out of Windows , Once you are at the login scree with the password prompt or the screen where the power buttons are visible, click on the power button at the bottom right -> Now before you click restart, HOLD SHIFT and then click restart.

 

Other than the bios I cant boot into anything, certainly not any login screens or safe mode

 

can you create a windows recovery USB using another computer and then set your bios to boot from USB first: http://windows.microsoft.com/en-us/windows-8/create-usb-recovery-drive

 

Have you tried using a single ram in other slots ? Especially the slots on the opposite side of the ones that youre usually using.

 

I was trying to but now it doesnt even post

 

At this point either try a nvram reset by taking out all batteries including bios battery [very finicky, can break part of the holder if not careful enough] and power plug for like 10min
or
just send it in if its still under warranty. <- safe route

 

Just tried that. Now it doesnt even POST, i only get a black screen when turning on


I also tried that with the CMOS battery to no avail.
Yeah I actually already had sent it to the shop for warranty but ended up going back for it as they would only start working on it next monday and I had to get some work stuff out of the hard drive

 

but it still posts when u put it in the old slot ?

 

No. Stopped posting.
Wtf is going on?! I'm gonna send it for warranty but it sucks.
I had a Clevo 10 years ago with a 7800GTX and it had issue after issue. I sweared I would never get another one but the P771DM looked like such a sweet machine. It's just riddled with problems like my old one. First a blown speaker, now this.
I'm just praying I dont lose any data as my latest backup is about one month old :cry:

 

You tried accessing the data from your PC ?

 

No, the particular data I needed to access was in my ssd. And it's a M.2 drive which I dont have a compatible laptop or adapter for.
Maybe I'll try getting it out tomorrow with a friend

 

It does only seem broken on the P75X models, though I can't speak for the P6 whatsoever.

Firstly congrats!! You're going to love your new laptop! How long do you have to wait? Be sure to add your system specs to your signature so we can all see the power house you now have,

1. The service manual is around here and there. Here's a one such here and there.

2. The long and the short of it is that BIOS is an old system and had limitations, they were hacked around with; the OS would load different system level things but UEFI was designed so these limitations wouldn't have to have creative solutions anymore. Things could be more integrated on a system level, features could be added and everything would be simpler to facing to the OS. Google will give you a much more detailed description if you're interested in the differences and the reasons why but there's nothing particularly fancy about its implementation on the P770DM-G.
Use the UEFI mode, the only action it requires on your part is making sure your boot drive uses GPT rather than MBR. It will come configured this way anyway provided you're having any modern OS installed. The only real con I can think of with UEFI is that it isn't always as compatible booting from older hardware. For day to day use there's no question, UEFI is the way to go.

3. I have mine configured with a single NVMe 950 Pro and a 1 TB HDD. What's the best combination of settings and software (e.g., BIOS or UEFI? Sammy Magician?)? The manual gives conflicting info. First, it says that IRST does not support M.2 PCIe SSD's. Then several sentences later it says "note that if your system has a single PCIe M.2 SSD then a second reboot will not be required" when installing IRST. ????

Well there's very little in terms of settings and software required. Install Samsung Magician, this will give you full access to configuring your 950 Pro, though again very little is needed in terms of configuring. There's no need for over-provisioning, but it will show drive health and allow you to enable RAPID mode which will use system RAM on occasion to increase speed in certain situations. It's a good thing and there's no need to be concerned about having less system RAM available either.
Install IRST if you like, as mentioned it won't see the 950 Pro, it's rather bland in terms of features.
The quote from the user manual is saying
If you don't have any drives that IRST will see then you won't need a second reboot.
IRST effectively loads additional system drivers for drives it can be used with. In order to load these drivers it must reboot. If there is only a single M.2 drive there is no need to reboot as there are no drives for IRST to attach these drivers to. Hopefully that's at least a bit clearer than the manual.

 

One of the best parts of getting a new system. Thanks for placing your order with us, feel free to reach out to me directly if you have any questions.

Also, if you need service manuals,drivers, or anything else, our tech support can help with that as well.

 

Managed to download my user folder into an external HDD (or at least it's in progress, knock on wood **).
What a load off! I was getting very worried. But apparently the SSD seems to work fine.
In the meanwhile my system completely stopped posting. I fear it's totally bricked.
I still think it's because of the new 364.72 drivers, but I'm not figuring out how can they **** up a system so badly. I'm guessing my 980m needs to be replaced

 

not surprising, see this post (click on the spoiler within)

I went back to driver 362.00 just to be on the safe side.

 

The firmware and drivers have a look of hooks into some very base parts of the chip. The risk of that is poor drivers can cause more serious harm to the chip than ever before.

 

359.06 \o/ to me it feels like all newer updates just give better VR support and some game optimizations.

 

I agree. What pisses me off is that I never update to the latest drivers this quickly. But with the last ones I was distracted and let Geforce experience start downloading it

 

Perfect! Thanks so much for the reply, and all my questions are answered (for now ). I'll keep the service manual for reference, and I'll go with UEFI with Sammy Magician (I'll skip IRST...no need for it based on your reply).

I'll probably get my laptop in about 2-3 weeks. I'm literally in Phase 0 out of 7 I haven't upgraded anything in years (kids and all kinda stopped that), so I'm very anxious to get it. I check the status about 5 times a day, even though I know it only makes it harder.

Thanks again,

 

@CEUOTC @myx @Prema - to save be trawling thorugh the other threads, is anyone aware of P775 owners with this same G-Sync issue. As mentioned previously Nvidia have been working on the problem for a while now but we have P775 running 364.72 and G-Sync works without any issues at all. Thanks.

EDIT - has it only been reported on P751 systems?

 

If it helps I have a 770dm and am running prema vbios v2 and the latest Nvidia drivers with no issues. Gsync still working.

With drivers following 362.00 only p751dm-g model has lost gsync.

I have many reports of g-sync being gone in all driver after 362.03.
I think it effects certain screen model on P7 as well as P6 but not P8:

http://forum.notebookreview.com/thr...os-and-970m-oc-question.790428/#post-10237199

 

@Prema - ok thanks. We have (only) had a handful of customers report issues i.e. a very small percentage, so either it's not a widespread issue, most people are running on the stock drivers or most people aren't reporting it to us. We started speaking to Nvidia quite a while ago and our contacts are eager to understand and fix the issue. Seems to only affect our 15" chassis customers and......

 

Yes, it maybe only the 15" LG screens in P75 & P65...I'll ask around...

 

Yup, that's what we were hypothesising as well.

 

Still have gsync after installing 364.72. but I failed to update nvidia 3d vision. any idea why? or is this only for 3d panels?

 

@jpsm it is only happening on the P75x models, as per your signature you have a 775 model.

 

That part of the driver may not have been updated, it is for 3d vision displays.

 

@XMG I assume my system is a P750DM-G.

 

OK, got confirmation that the screen that lost g-sync regardless of system is the LG LP156WF6-SPB1

Clevo is also directly pushing NVIDIA to fix it and waiting for a new driver...

 

364.72 has other issues anyway.. better to switch back to 362.00 and wait until new driver release, and then at least you have G-Sync while waiting

 

So, once I get my laptop I should be fine to update to 362.00 as long as it does NOT have that monitor, right?

 

As I read it, that is the latest version that works with that screen.

 

My bad...I didn't type that out well. I meant that since the 364.72 version is buggy for other reasons, the best option is 362.00 as long as you don't have that specific affected monitor (for those that have that affected monitor, the best option is version 354). Thanks for catching that

 

Aye. 362.00 is what I am using atm.

 

What's wrong with 362 with that monitor (the 15inch)? Drivers after 362 cause gsync loss on those 15.6" LG's, but 362 is fine

 

Just to note for the record that I too have lost G-Sync since updating the drivers. Bit of a rant here, but this situation totally sucks. Wonder if many less visible features have been lost as a result of driver updates that broke them?

Nvidia must know its drivers are broken and it must know why. But why no fix?

Edited to add: installed 362.00 and sure enough, G-Sync is back.

 

362.00 is one of those golden drivers
