That's odd. Will take a look at that when I get the chance. Hard to test things for me though, don't have a system like yours. Neither a 880m. If I find time. Will need a dump of your bios either way. Not sure what you exactly mean.... what's the problem with HWiNFO and fan control? Nonsense. The 880m just has very little headroom by default. The voltage is set relatively low for the max default boost. It occured to me that some cards might not perform properly with the settings in the modified vbios, some might need more than one volt for 993MHz... Another issue is that many systems don't seem to be capable of running 993MHz sustained due to the temps. Re-pasting should be self-explanatory for anyone thinking about ocing, but I'm mentioning it again anyway. Nope, just that one version. That's incredibly odd to say the least. Seems like part of that issue got solved by changing secure boot related settings. As for overclocking, well that can easily be due changes made in the nvapi by nvidia. Then the oc tools need to be updated as well. But to be honest, I wouldn't be surprised if it simply was due to the crippled nvidia drivers. Many of you might not have noticed, but ever since like 304 the nvidia drivers have some serious issues. Not just performance related, but also when it comes to overclocking. And boost. Etc. It's there for a reason, hint hint. With the modified vbios your card runs effectively faster than with the stock version, therefore you have to expect higher temps. New thermal paste would be a first approach to this issue. Since Nvidia doesn't give a shit about this forum anyway I'd recommend everyone to file a driver bug report. They get read at least. The more the better. Instability might have happened because the voltage of the modified vbios was too low for your card. I however don't believe that you run 3 hours at full boost with the stock vbios while having lower temps, that's simply not possible, unless you increased the voltage when using the modified vbios.

For the driver installation see the post of @J95 above. About the white screen issue - that's just a matter of drivers. Nvidia still didn't fix that, I recommend you send them a bug report. The issue can be resolved by installing the drivers in the proper order, I got it working on my M15x with the 780m.

No. Unless you used liquid ultra or similar and smeared it all over the components Yeah, for me it sounds like a defective GPU. As I said, if you have the wrong vbios it should boot fine, but black screen only. Huh, that's odd. Another guy recently PMd me and seems to have a very similar issue... no idea what's the problem, really. Yeah, well, I was away. Ski tour Will be away again soon

I agree with Genetics, sounds like a hardware issue. The only thing you can check is whether the pins of the card are clean and not damaged or similar. The 7970m works with all vbios version in the M15x, except for the P1x0EM and MSI version, with those you only get a black screen. Bake again? Temps and time you baked it?

1 - read post nr. 1 2 - download tools 3 - follow instructions in post nr 1 Thank you, appreciate it. Already got what I needed from a different user.

I can't mod anything if I don't have a bios dump. And some additional information. E.g. a dump of this tool run in DOS.

Nice improvement! Also, don't use furmark if you want to have your card in a working condition.

Sorry for my absence in this thread, I'll try to catch up on things. I'm looking for a y410p / y510p serial nr, if anyone wants to help me please send a PM.

I doubt it will help, the 240W PSU is sufficient for your setup unless you would want to push it to the limits, which is not possible anyways. What's your system? I have a hunch that the default voltage of the vbios mod might be too low for some cards. Try a run with like 25-37mv more.

Try increasing the voltage of your card by like 25mv and run again.

I wouldn't know about the cooling since I never had an MSI, but I guess if you have proper die contact it will be possible to cool it well enough. 240W should be sufficient unless you head for benchmark world records. The vbios works on the msi board, that being said, MSI has sometimes some special stuff in their bios... if it doesn't perform properly then it might needs some adjustment for the MSIs.

That's odd... did it switch to 3d clocks? I'm not sure how the current driver handles battery mode, if it switches to 3d then it's possible that your system has a very strict current limit for the battery that would cause issues when the gpu switches to the 3d state in battery mode, at least with the modified vbios. Yes. 1 - Yes, since your system officially supports the 680m. 2 - Not sure what you mean... Restoring the vbios? Yeah, make a backup and then you can flash it back anytime. If you loose it... well, you'll find a copy of the vbios on the web. Or here, if you ask. If you're referring to the post two above this, then it's because your system run at stock and the other was overclocked. Right, I never uploaded a version for the Asus. Need a copy of your vbios for this. BIOS stuff is kinda off-topic here. Depends on the card... some might not be able to go much above the stock settings with the voltage set in the mod vbios. Also the new AWs are limited when it comes to overvolting. The mobo doesn't allow much more than the stock voltage. It simply won't provide the required power to the card. Nvidia has quite a mess with the more recent drivers. The newest one is certainly not recommendable imo. The suggested driver above is one that works pretty well, but of course it lacks support for the most recent games, so you might just want to try different drivers and find one that fits your needs best. Drivers. That would be my first guess. Try an older one, e.g. 327.23 if you want to bench.

60°C is a lot for idling, unless you live in a desert. Or wait, do you mean that's the max temp if you play games? That would be super low... If you really didn't change anything and didn't overclock... it almost seems like a hardware issue. But software is more likely to be causing things like this. Hardware failure would be very unlucky.

150€ for that setup? Someone must have been lucky... 750€ sounds fine for that kind of hardware, not too expensive imo. The first one, "CPU-->Thermal paste-->Copper shim-->Thermal paste-->Heat sink".

Yeah, that's kinda what I'd expect. Sorry... that's simply your motherboard limiting you. Dell really implemented some strict limits on all voltage rails I'm afraid. The card itself is capable of much more, I benched it at 1200MHz+ in my ancient M15x with not throttling at all...

Turn off secure boot, allow legacy boot, try again.

Hmm, maybe there's just not enough pressure between the die and the heatsink for this paste... not easy to fix though. You could bend the mounting clips up a bit... anything else would require a hardware modification. I'm not sure what a good temperature is for your system, but you certainly shouldn't be higher than with the stock paste. ICD is a more viscous paste, doesn't "bake out" as fast in my experience, but a fresh repaste with MX-4 and ICD always got me about the same results. Also the last time I was messing with a Clevo I used MX-4 as well and got good results.

That looks excellent to me. You did plug in the fan, right?

You say the temps are ok, how high are they actually? After gaming a while and during idle? It's odd that this behavior appears apparently out of nothing. You didn't update the drivers before this started happening? Or any other changes at the system? Do you overclock the GPU?

The black tape around the die is something certain vendors put their to prevent the thermal paste getting all over the tiny capacitors around the die, it doesn't have any other functionality and is not required. All you need for a proper re-paste is cleaning the die as well as the heatsink, apply a relatively small dot of paste on the middle of the die and then mount the heatsink. I don't have pics just now, but if you search the forum you'll find several repaste guides with pics I think.

Which notebook are you using?

MSI AB has its issues, I found that Nvidia inspectors follows the recent nvidia api most closely and therefore works best. The voltage workaround should still work with MSI AB though, it's just a matter of configuring it properly. However since with that workaround the voltage controller will be set to a different mode, you'll be at the set voltage all the time, even when idling.

If you post a screenshot of your device manager showing the hardware IDs of your GPU then I can mod you an inf file.

That's correct. But as I told you, I don't have a system to investigate myself and I won't spend time on this unless someone is seriously willing to mess with its board. Yes that's right. Actually ca 835MHz should work as well. After all it's called "OC edition" not "UC version". If you want to run at 700Mhz the stock vbios will do the job as well. As mentioned, that's software related. Did you do something to try and solve this? I.e. using a different driver, re-install the benchmark, using system restore etc.

That's not for sure, I have no idea how thick the copper layers in the board actually are. Also it's kinda impossible for me to tell you what is required to do when I don't have a mobo to look at.
