That is not possible without hard modding - I have no idea how to do it, but it is absolutely possible to do it - you will however need some EXTREME cooling solution better than standard.

Perhaps its your DX that is broken somehow or even windows itself (not unheard of)!
try this: Go to your Metro Last Light installation folder, redist folder, inside you have several folders, one of them is DirectX, open it and run DXSETUP.exe, if this doesn't fix your issue, one of two things: Gordan is right and your card was unstable at those clocks and somehow your software reported higher clocks than your card really had (not unheard of again) OR its your windows installation that its broken and you will need to re-install it!
I suspect its the DX, do it and report back! thumb.gif

By soldering a resistance to the back of the card, it will void your warranty and perhaps kill your card in the long run as the 780Ti has a very weak power section, unless you go for lower voltage but its always a gamble! I talked with doctakedooty and with the help of Ftw420, i will work on a parallel resistance in a dip-switch (when i find the time that is)!
That way you can set the voltage before gaming and after just switch back to the default voltage! smile.gif

Luck and silicon ageing most likely.

You never gathered conclusive evidence the setup was not generating errors, and it is statistically possible you were just lucky in the first place. Ambient temperature also plays a factor, and if you had a UPS with logging, you might refer to that to establish if the cleanliness of power going into your computer has changed.

Software and driver updates can also have an effect - more optimised software can cause a higher load on the hardware which can cause instability, especially on systems that weren't tested under maximum repeatably genera table loads (hence why I mentioned OCCT and CudaMiner).

Finally - silicon does age. Intel, for example, pre-age their silicon to ensure there are no nasty surprises later. Even so, on most chips tuned to the absolute limit of their stability and run under high load 24/7 for a few years a stability degradation can be measured; they can start requiring higher voltage, lower temperature, or lower clock speeds to remain stable.

Hey, does the below scores seems fine for my machine, currently running with a i7-4770k @ 4200, 2666Mhz ram (16GB), Raid 0 OCZ Vertex 4 256 x 2 SSD, EVGA GeForce GTX 780 Ti Superclocked ACX 3GB

Don't suppose you have a link to where it is posted in this monster thread? I saw it before but forgot to save it redface.gif. I now have my card out of the loop and would like to go ahead w/ the vmod.



As for Asus RMAs, the RMA of my Z9PE-D8 WS was one of the most painless RMAs I have. Besides OCZ I have never had a better quicker experience.
