Nvidia re-disables GTX 900M overclocking with latest drivers

[HEXUS]

The company had previously re-enabled overclocking in February after community outrage.

Haha they just can't make up their mind!!!!

Disabled by lock bit? So it's only disabled if notebook OEM sets it so in the BIOS at the factory?

Nice way to shift the blame ;-)

Sounds like they're trying to limit overclocking to notebooks with thermal designs that would actually SURVIVE overclocking. Most designs are already thermally constrained and will throttle under even normal use (as the designed decided to trade off performance for compactness and weight). With the notebook OEM ultimately responsible for both the thermal solution used, AND the warranty of the machine, having the abll be in their court makes the most sense.

It's not fair to lock down those who DO have one of the massive desktop-replacement notebooks that can handle overclocking with aplomb. But it's also a really bad idea to leave overclocking enabled on designs that can't handle it. It's not just a 'you might get lots of instability and crashing' issue, but you could literally cause physical damage to the notebook. Nvidia and AMD both have been hit by hardware failures arising from solder cracking in the GPU interposer due to thermal shocks, and that's with stock clocks. Overclockging and/or overvolting could damage chips that are fully in-spec.

You make valid arguments, we have contacted Nvidia to get a more detailed response about how this works. If it's model or vendor specific, which ones will be locked down and which will not, etc. We will post a detailed response when we get it.

Here's an official response from Nvidia:

"There was a small software regression that caused this and it is now being fixed, we’re sorry for the inconvenience and updated driver will be available next week. In the meantime, if you’re using OC features on your notebook then hold off updating the driver or rollback until the new one arrives."

Released early this morning - 353.00 hotfix, and the only thing on the changelog was a note saying they fixed exactly what was in Tarinder's post.

to be fair, you don't get a laptop if you want to overclock...
