If it's been overclocked for so long, the VRMs might be damaged. Even though my overclocking isn't extreme, these GPUs aren't usually built to handle heavy overclocking. I've only begun overclocking recently, mostly sticking to stock performance. Now that the device is nearing the end of its lifespan and I'm not concerned about its fate, I've been testing its limits. If that's the situation, I'd increase the power limit as much as possible and experiment with adding voltage. You might still get some extra power without artifacts. Go slow—don't risk damaging it—but setting the power limit high signals to the GPU that it can draw more, not necessarily more immediately, but when needed. Worth a shot, and you already know what happens if it fails.

If thats the case then I would up the power limit as high as you can go and try adding some voltage. You may well still be able to get some non artifact extra power. GO SLOW, you don't want to just cook the thing, but setting the power limit to its highest level just tells the GPU it can draw more, it doesn't necessarily feed it more, only what it needs.
Worth a try, and you already know what happens when it doesn't work.
Just gave it a shot, turned up power limit to the max and voltage to +13mV, and it caused artifacting, but a completely different kind. Normally when it was happening before it was causing different colored dots to flash on screen, but now it's causing pixelated squares to flash at me all over the screen in addition to the dots. Here's what the monitor looked like while under load.

Squares is worse. Yeah I think stock is it, don't mess with it.

Squares is worse. I think the stock version is better, don't mess with it.
It looks like voltage was definitely the issue there, setting everything at stock and increasing the power limit seems to be working just fine.
Power limits only make sense if the GPU needs extra power, like during overclocking.
I've noticed many people using 290X's and various "Southern Island" cards, and they're seeing better results after swapping their heat sinks. Think about trying it—this could raise temperatures more efficiently and provide extra space for overclocking. You've got nothing to lose.
