Gtx 770 Vram OC help (artifacting)

So i bought a 2nd hand leadtek gtx 770, and i tried OCing it's Vram to 3800mhz, after a bit of unigine heaven my display crashed with some red block artifacts

 

Is it normal for a gtx 770 to not be able to push 3800mhz on vram? And is it normal for artifacting to happen when it can't?

 

Edit: also, does anyone know any good VRAM testing apps?

Correct, if the OC is on the edge of not being stable like that, artifacting can happen.  If pushed a little further it will just crash.

 

I'd just use it without an OC.  You're not getting a huge bump in performance with one even if you somehow get it to run at 3800.

Not all cards are equal, cards with Samsung GDDR5 VRAMs are known to overclock significantly higher than Hynix or others. I personally dont bother with VRAM overclocking as your overclock might be stable until the very last second you kill one of the vram chips.

I'm really just doing this to test and make sure this card doesn't die on my like my last one did. Do you happen to know any good VRAM testing programs?

I'm also panning on using it stock, but for the first 2 days i want to have it overclocked to make sure that this card isn't on it's last leg

OCing it may just make it's leg the last one.  Now how I'd stress test an old GPU.  You can't know when it is on it's last leg, and pushing it hard can break it where regular usage wasn't going to.

 

Besides, just because it may handle an OC for a couple days doesn't guarantee anything at all.

Can you explain how you'd test old GPUs then?
