Hi everyone,
 
I've had my 1080Ti FTW3 Hybrid for a few years and have noticed in the last month a decline in feasible memory overclock via PXOC 1.0.6.
 
I used to run all day long with slider at +655 MHz, with clock +38, Voltage +100, and Power/GPU Targets set to max. Now I have to reduce memory to about +500MHz to remain ok. I've had a read around and have seen the restorative healing magic that can occur with thermal paste reapplication and have thought to do the same, but can I first ask a few questions?
 
1) Does this affect warranty? I can be careful but if I am risking the warranty by being clumsy then I'd prefer to explore RMA.
2) Is there any official guide for this task?
3) Is this even an RMA-able concern? It's still outperforming the card specs so in theory is ok but I'm an engineer and I know that changes in system performance without explanation are where things tend to go wrong.
 
thanks for your time reading,

It will not affect the warranty as long as no end user damage is caused.

The memory has thermal pads on them, and typically they don’t dry out all that quick, so the lowering clock may well be degradation over time.

If you want to try replacing the thermal pads and thermal paste, there are hundreds of videos on YouTube and steps outlined in articles, but there is no official guide from EVGA for this task, as far as I know.

Since you would be refreshing everything, I would suggest picking up a cheap soft bristle tooth brush and some isopropyl alcohol to assist with the process. The soft bristle tooth brush can help really get all of the old paste off without causing damage to components.

When you reapply the thermal paste, make sure you spread the thermal material in very thin layer across the entire die, so that every tiny spot is covered before reassembly. I use the edge of a credit card to get a good consistent spread and it hasn’t failed me yet.

Thanks for the guidance, much appreciated. I'll check out the videos. 
 
I remain interested to know if I'm truly in RMA territory, but perhaps an inspection of the undershroud environment and a removal of dust etc. might be the answer I need. Still, I'm not 100% happy about taking a screwdriver to high end card that's still under warranty (I extended with EVGA at purchase).

Your options, as strange as it sounds, is an hour of taking the card apart and cleaning it, or sending it back to EVGA and waiting up to 2 weeks to get a card back.

If you paid for the advanced RMA, you may be able to use this card you have until tragedy replacement arrives, dependent on your location.

Honestly, taking the card apart is really easy. The only part that is usually the scary moment for me is disconnecting the LED and fan cables because I am clumsy and feel like I will drop everything.

If you want to speak with support about you options, you can reach them through phone or email. The email is support@evga.com

As luck would have it after five years my 6700k (and possibly my motherboard?) has just died so it's time to get the wallet out and build a new system - makes me wonder if there was an underlying issue somewhere else that was causing the crash. I'll come back in the coming weeks/months and update so that others in similar position may get help.

An 'underlying' issue such as your PSU?  Also, your GPU may be be perfectly fine. With recent updates to Windows and drivers, I've also had to lower my GPU memory clock a bit. Games like Division 2 would randomly crash to desktop with +600 on the memory and were perfectly fine at +550. Quite a few folks do not know this, but drivers can also change the memory sub-timings which can of course affect stability. Also retired EE here.

Much as HeavyHemi described, one thing to keep in mind is that overclock stability can fluctuate over time due to different driver versions.  It's not a bad idea to run a couple benchmarks every few months at your overclock settings at the time to get a snapshot of your performance for comparison.  Because different driver trees are sometimes more stable or more aggressive towards performance, this can affect your overall overclock (but might actually improve performance!).
 
Don't overlook long-term performance changes due to all the drivers, windows updates, and other software changes.  At the same time, don't forget to check if your performance has actually improved over time, even with lower clock speeds.

Possible yes, PSU is EVGA 850 P2, and is only three years old. I have a second PSU, but (confession time) I can't for the life of me remember if it was functional - I think it was, and I bought the EVGA one to increase headroom from 650 to 850W. I tested with it and got same result.
 
First new PC bits on the way, update to follow.

P.S. good to see I've got some good heads on this thread (all the EE's) thanks for your input, very valued for myself and others who may land here via google.

Hi everyone, 
 
Just to update, turns out that both CPU and motherboard were faulty (!). I've ran the card in an interim PC at previous PXOC settings and have not had any problem which is fairly interesting. Card is back on song.

How did you confirm the CPU and motherboard were bad? As I intimated earlier, simply a power supply dropping voltage under load can to this.

I bought another identical motherboard and a budget CPU (i3-6300), did some swapsies and soon discovered the bad news.

Not really sure why you'd do that if you were going to update the entire system. That's another GPU right there.

Ebay my friend. Second hand mobo and CPU, so £160 total. If the i7-6700k was ok then it's worth more than that, and I could still then sell the rest of the bits. Sadly it's not ok so it looks like I have a PC that I can give to my folks (imagine, basic cpu with Kraken X61 and Z170 Gaming 7 mobo running two m2 drives....all being used for web browsing...)
