TDR/Framerate issues since RoS

Hello friends and fellow Boxers!

Michael G. Here with need of dire help! When RoS was released I began to experience drops in Framerate and random screen freezes (hitting windows key would reset the box that froze).
Recently I began to get TDR errors leaving me on the dark for 5 seconds while my GPU reset . Which is very scary since I multibox on hardcore. This has happened inside of rifts, in town, even salvaging at the blacksmith.
Here is my setup:
Toshiba 32 inch television (I use the HDMI port)
Asus z87 deluxe mobo
Intel i7 4770k -4.2ghz 10mb cache (liquid cooled)
EVGA GTX780 - 3gb (runs at 45 degrees or less)
18 gigs of ram
I use 2 Solid State Drives; 1 has windows/all aplications..the 2nd one is strictly for Diablo 3
Corsair 650watt single rail PSU. (I heard having multiple rails isn't good)

Now for the troubleshooting Ive done:
I've check the bottlenecks and nothing is anywhere near 50%
Ive lowered the settings to performance on EVERYTHING
-nvidia controls lowers to performance over quality
-ditched Aero windows and unchecked very box
-diablo 3 runs low everything, unchecked vsync etc.
-admin tools>power options>display (off)
-I've tried older drivers and newer drivers. Tried to uninstall 3D nvidia drivers even the HD audio drivers
-re-installed OS/updated all drivers
-ran multiple memtests -came back ok-
-did a motherboard BIOS flash and came back OK
-diablo is using all processors in all windows
--I used windows mode full screen
-went into REGEDIT and change the DWORD to "0" and also changed it to "10" after "0" didn't work.
.....after doing all of that it still happened

So I tried to take off window mode full screen and play on full screen with a 1600x900 resolution instead of 1920x1250
I don't play with stacked screens. I play with one ontop and 3below it in smaller boxesi was playing for 6 hours and no problems(record for me)
The TDR issue went away, the FPS would still drop from 50 to 38 now and then.but NOW an even worse issue happens! My screen turns black, then the fans on the GPU/chassis/PSU turn on full blast(I can hear it) and my computer crashes. It will restart automatically and say windows was not shutdown properly.
It has happened twice. The first time happened in town while moving to the blacksmith from the rift portal
The second time was in the middle of a rift boss fight... Luckily I lived since it was on normal

... Is my monitor too big? Should I try to play on one of my 24" or 28"?
I'm stumped..

Disclaimer: I will not be held accountable for any damage that may occur to your hardware from increasing voltages. However, many people, including myself, increase voltages beyond the default settings, and while 99% of people have no issues, I'm sure there are 1% of people who burn up their hardware.

I'm stumped..

Have you tried to bump up the voltage on the GPUs (through MSI Afterburner or other third-party tools) or even bump up the voltage on your North Bridge in your BIOS? It's been some time since I had to mess with this, but I'm almost positive that the North Bridge handles part of the voltage delivery to the GPUs (outside of what the PCIe 8/6-pin connectors handle from the PSU).

North Bridge voltage in your BIOS is likely going to be named "PCH Voltage" and you might want to give it a slight bump. It's default is probably something like 1.05v, and you can most likely, and safely, try anything up to 1.10v and still be just fine.

When I moved from 2-way SLI to 3-way SLI with my GTX 580s I experienced the black screen crash with the fans ramping up quite often until I increased my PCH voltage -- It seemed the GPUs just wanted more juice and the motherboard wasn't giving it to them. I've since upgraded my setup, but I also use EVGA 780Tis, and every once in awhile I can get them to bluescreen the system, but I don't get any TDR crashes anymore unless I'm purposely doing something I shouldn't be.

Ok I will try to increase voltage when I get home from dinner with wife!
EDIT:
Would getting a higher watt/amp/voltage PSU make the process of increasing the voltage Safer???

No. The only thing a new PSU would fix would be any voltage instability (including undervoltage).

And I would change the voltage through the motherboard bios ? I am new to overclocking

Voltage of what? The GPU or the North Bridge? Here's what I said in my first reply:

Have you tried to bump up the voltage on the GPUs (through MSI Afterburner or other third-party tools) or

bump up the voltage on your North Bridge in your BIOS?

Also, if this GPU came from EVGA overclocked, then you should drop the speeds back to factory default in order to see if that's the issue.

I'm not sure what north bridge is. It did not come overclocked.
I'm on my way home now and will try all the suggestions thank you

I'm not sure what north bridge is.

It doesn't matter if you know what the North Bridge is or isn't... the voltage for it is listed in your BIOS as "PCH" and it helps feed PCIe slots with voltage. Not PCH VRM, not PCH PLL, not PCH VLX... just PCH Voltage. This is all the information you need to know in order to increase the voltage a bit -- Again, I would suggest trying 1.10v. If the voltage is already at 1.10v or higher, then you may not want to touch it.

But adjusting the voltage in the BIOS wasn't my only suggestion... I also suggested to download a third-party program (I'd recommend MSI Afterburner) and bump the voltage on your GPU a few notches.

My original reply contains all of this information.

Ok I went into x79-deluxe mobo and the PCH voltage was default minimum running at 1.100... I bumped it up to 1.1875 (it said the max was 1.700 ..
I also bumped the gpu voltage up +12.5mV (which was the minimum allowed)

Should I lower my memory clock and gpu clock too?

In your original post you list your motherboard as a Z87, but now you say X79. X79 and Z87 are two entirely different motherboards with two entirely different chipsets. I'll assume you actually have a Z87 motherboard since a 4770K doesn't fit into an X79 motherboard.

Should I lower my memory clock and gpu clock too?

Not yet. If you change several things at once and it fixes it, you'll never know what the cause was. Now you just have to play the game and see if you can get it to crash again. If it does, then you might try yet another bump in voltage on both the PCH and GPU -- You're generally safe if you stay within spec and below maximum limits (assuming thermals are fine). I probably wouldn't go higher than what you've just set the PCH to, or more than 2-3 "notches" on the GPU; because if a little extra juice isn't going to fix the issue then it's probably something else altogether.

Do you have a GPU tab in your BIOS? It would be a sub-option under the TPU tab. If you do, then that might be causing the issue, but I honestly don't know what that option in the BIOS is for... but it might be worth bumping the voltage there a bit under Function -- Although, I don't even know why those extra options are there. /shrug

You SHOULD NOT adjust the VCCSA.
