One of you guys with artifact / scan line issues should really try running with some form of enhanced cooling and see if that helps. Even if said "enhanced cooling" is just putting a box fan behind the monitor, removing the back plastic cover, or just cranking up the AC in your room.

I have a feeling it will help both more stable overclocks, and less "burn in".




Speaking of which, I've been thinking of the "burn in" people keep mentioning, and as I've mentioned before, it just doesn't make any sense... but then I realized that's because it's not burn in, it just looks similar. It likely has more to do with the controller board than the panel itself.

At any rate, despite my finding that my 680L was far more capable of overclocking this panel than my 560Ti, I still haven't been getting artifacts, scan lines, crashes, or "burn in" like effects, aside from a single frame with a tiny artifact when my room was really hot. In general I try to keep my room fairly cool. So... do the speculative math yourselves, and give my theory a shot.

If it turns out the PCB just needs better cooling, there are some self-adhering 5 and 2mm tall heatsinks you can pick up on frozencpu and xoxide for dirt cheap to fix the issue for good wink.gif

Just took a quick measurement of the exhaust vents on my overclocked x-star (settings shown in above post). As I said, room temp is 69 degrees F. The exhausts range from 81F to 100F. There is definitely some localized heat buildup going on in there.

If anyone is brave enough to crack their panel open and run it overclocked with the back off, some temps of the actual components compared to ambient could be real useful.

You should try checking the temperature before oc and after oc with the same time gap, to see the difference.

Couple of questions...

If I don't watch movies on my computer except YouTube, do I need to worry about the 24fps multiplier for smoothness?

Is there any application that will keep my monitor at 60hz when at the desktop, only bumping it to 120hz when gaming? I went back and forth between 60, 96, 120 Hz and I really can't tell much difference with my mouse cursor. Maybe it's my eyes, I'm not sure. I was so concerned I ran that Pixel Clock Utility to make sure the boxes lit up smoothly to verify I was really running at the specified Hz.

Those with overclocked monitors, are you using Vsync? Are you using D3DOverrider to force Triple Buffers with VSync in DirectX games?

Thanks!

The thing with the 'burn in' effect I am seeing with my monitor is that I can also see some flickering on the right side of the panel that has the burn in look.
It seems this happens only when I overclock it.

Good idea, setting it to 60hz now, lets give it a few min and see.

Not as far as I know, sorry. As for the movies, if you're running at 60, 96, or 120 as you stated, all of those values are already multiples.

That reminds me though, what's that little utility I keep seeing people post screens of with all the big grey boxes than light up in sequence to test refresh rate and pixel response times? I can't seem to find it. I guess I'm retarded.

That sort of supports my theory that the "burn in" isn't really burn it at all, and is in reality a manifestation of an unstable overclock at the controller PCB level. Can you try improving your cooling with a box fan, removal of the rear plastic cover, some heatsinks, stronger AC, etc?

Ok, the room ambient is now a few degrees cooler at 67 (AC in my building isn't working, so I just have to live with the flux) but still fairly close.

The exhausts now range from 78 to 94 degrees. Interestingly, the hottest point is no longer in the same spot (previous hot point was near the center, it is now at the right side).

You can see the timestamp of the posts yourself, so draw conclusions from this as you will. (it's been about an hour for anyone reading this late)

It is the display: http://en.wikipedia.org/wiki/Image_persistence
Nothing to do with the control pcb.
And cooling the display controler would not really help with overclocking.

Hey guys, I'm having trouble with overclocking.

I'm running a GTX560ti 448 with 314.22 drivers.

When I try to apply the NVIDIA Pixel Clock Patcher, all the limits are found and I apply the patch. I then restart my PC but my resolution has reverted to 800x600 and I can't find my Nvidia Control Panel. I have to unpatch and restart for my drivers to appear.
