Hi there,
 
I bought the EVGA GTX 780 Classified a few months back, and can't seem to get any program to turn off the LEDs on the side of it.
 
Neither the program posted here on the EVGA forums last year, or Nvidia experience works when I try to turn them off.
 
Now, those LEDs are *REALLY* bright, and my PC is in my bedroom and doesn't get turned off at night as it's got various scheduled systems that run overnight (I'm a games developer). The damned thing lights up my whole room!
 
So, how do I turn them off?
 
I mean, there's no way an engineer at EVGA would design and produce a £400+ gfx card where you _COULDNT_ turn them off. That'd be such appalling design that they should be sacked for it. So they must be able to be turned off some how. I just can't find out how!
 
Please help!
 
Thanks.

They don't turn off.  This has been posted many times and there is no way to do it.  Best you can do it take some tape and cover them or use a darker colored marker to darken them.  The LEDs are actually diagnostic in that they each are an indicator for a particular voltage point on the PCB.  I posted this a few weeks ago and I can dig it up, but if you do a quick search you should be able to find.  If one of the LEDs was not lit, that means there is a problem with something on the card. [edit]  I believe the post I am talking about was in regards to a 770 Classified but same LED configuration as the 780.

Also, the LEDs are meant for Ln2 cooling, according to K|ngp|n. The reason is when the nitrogen is giving off smoke, you need to be able to see if they are lit up. If a light goes out, there is a problem. I understand that may be frustrating, but you did buy a card that is specifically geared toward people that want to use Ln2 or Dry Ice cooling.

They have also stated many many times, over and over, that they will not make a way to turn them off.

Well, its not really "smoke" that the LN2 is giving off though, it is vapor as the liquid nitrogen "boils" and changes phase from liquid to gas.  But I think we know what you meant, but as being a dorky nerd, I felt the need to clarify

Tape those suckers up if they bother you, not worth your time and
effort writing a complaint that will achieve nothing.
As stated above, they have a specific purpose.

The problem is that the intended purpose for those LEDs isn't documented on seller product pages, or on the box, or really anywhere other than extreme overclocking sites. Checking specs and reviews on the common review sites - they don't talk of using it for LN2 cooling (whatever that is). Now, to all the hardcore minority on these forums, sure, it may be common knowledge, but to most of the consumers it really isn't common knowledge at all. Most consumers are going to look at specs and prices and the most common review sites.
 
The fact is that I spent a large sum of money on a card that doesn't support a basic feature like turning off the LEDs. In the 21st century of gfx cards, that's shoddy. Turning round and saying "Oh well it's your fault because you bought a card that has a 'feature' for an undocumented use that's only word of mouth knowledge between a minority amount of users" just isn't good enough.
 
I'm still intending to write to EVGA's lead engineer and head of marketing, and yes, nothing may come of it, but if it means in the future they stop and think for a minute about the capabilities of the feature set they're implementing, then it was worth it.
 
Would I take a refund for this card if it was available to me? Yes absolutely, and I'd buy an alternate card.

I am going good to mention one very important thing. I don't want you thinking I am trying to be a jerk or a worse. You say the card isn't advertised as being used for LN2... Or at least not anywhere that you have seen. Correct? Right next to the power connectors is a tiny white switch. The switch to the left is connected to another Green Led on the back of the card. That led is labeled "Normal". Now, switch it to the right. The led switches to one that is Red and Labeled "LN2".... That in and of itself Is more than enough advertising to prove this card is meant for extreme overclockers, as "Normal" cards rarely have that option.

My point is, I just Google Classified GTX 780 and came up with three of the first ten review talking about extreme overclocking for this card. I am not saying it is easy to find, because the review is how the card comes from the factory, but it mentions the availability of the LN2 pots and extreme overclocking. What very few articles covers is the LEDs and their purpose.

When you email them, or snail mail, expect the response that you bought a card meant for enthusiasts. Not too many people want to spend 450-500 dollars just for the specs, but because they researched everything about it and specifically wanted that card for its intended purpose.

The classifieds have been around for years, and the LEDs have been on at least most, if not all, models of the classified. The standard PCB doesn't have them though.

That's just some thoughts. Sorry you aren't happy with your card as is. You could probably sell it for a good price and get the 780Ti at little to no extra cost, and those don't have the LEDs on the side.
