So, I order two 1080 ti, one a beast, I have not found its overclocking limit, it literally overclock to 2500ghz core and uses hardly any power, the other card won't run at 100 power target without freezing my system.
I had installed waterworks onto both cards, when I realised one was defective I refitted the reference cooling unit when to my horror I found that I had lost one small half of backplate which had the serial on it.

Long story short scan and evga refused my rma on a clearly defective card so I was forced to buy a third.

I now use the defective card as a dedicated physx card limited to 80 power target..

Sorry about that mate, but it is clearly stated in the terms and conditions that you have to send the card in the same condition it was when you got it out of the box. I understand it sucks to have lost a piece of backplate, but tbh it is also not EVGA's fault.

First, i highly doubt the one card runs at 2500mhz under load. If so, you have the best available golden card ever.

As for the backplate, you need to look for it. It has to be somewhere close by unless you threw parts away after putting the waterblocks on.

Edited your post and sendimg you a pm why.

First and foremost, all users should keep their own backplate. The loss of the serial number attached to the backplate will be the reason for denied warranties. You need to keep your own backplate and that isnt a hidden clause anywhere.

There is no way that card hit 2500 mhz, even if on LN2 at this point, sorry bud.
 
Did you mean 2050?

I don't run it 24/7 at 2500 as there is no point, gpuz shows no performance reason, I know it sounds unbelievable but it's true, I have it running at 2100 currently due to sli limited.

The card auto boosts to 2000 with a target of 120 and no other change.

I threw the backplate away with the water block box by mistake.

Well, I guess I have an overpriced physx card now, all I need is games that support it.

You can use GPUShark and snap I image of it and post it showing that the card is running @ 2500MHz.
I will make you an offer.

No I didn't actually.

Is there a chance you can retest and post the screenshots from GPU Shark?

This is as stable as I can see the 1080 Ti so far

is those insane overclocks stable in other things then gpu shark? As 2151 seems pretty impressive for the 1080ti

nice..............

  Bumped it up a little tonight. +260 now.
 
So Far I have got one Error;
02:10:39:WU02:FS01:0x21:Bad State detected... attempting to resume from last good checkpoint. Is your system overclocked?
If I get a second one I will put it back down to +250 @2151MHz
