Watercooling might improve overclocking, but I doubt it.
What are you using to overclock? catalyst? Trixx? MSI afterburner? Try using MSI or Trixx. If you know how to flash a bios switch over to sapphire's Tri-x bios, but I'm not sure how capable the DCUii is with bios switching considering it's not a reference card; I know the Tri-x has room for a custom bios. There's some risks involved with flashing a bios, so take time and learn how to do it properly.
What are your VRM1 &2 temps? Gpu-Z shows vrm temps assuming your text isn't overscaled. Your core temp might not be an issue but vrm 1 might, in which case watercooling would benefit your overclocking.
I get a stable 1150/1500 OC with my Tri-x with a +75 mv and +25% power increase. I haven't at all played around with my overclocks, but getting it that high was a breeze for my card.
No-go with Afterburner either, guys. If I slide the memory clock over to even 1400, it immediately crashes the card when I hit apply and my screen goes black. I have waited for 5-10 minutes to make sure it isn't just a weird driver crash, but nothing... My only option is a hard-reboot.
In gpu-z i have vrm 1 and 2 temps of 28 and 31, respectively, at idle, and 81 and 67 at full load, at 1050/1350 (stock for this card).
All-in-all I'm just gonna stick with it despite the weirdness. My plan is to put my chip and card in a Hadron Hydro, with a small EK res/D5, a 240mm radiator, and blocks on gpu/cpu. I have heard conflicting reports of the 290x fitting, but I'm sure it would with a bit of finicking.
I wish just once I could get a golden-anything though. I have a corsair vengeance memory set I rma'd 2 times in a row for some sort of defect (1600 mhz 1.5v 2 x 4gb, not anything crazy, and the set they sent me for the first RMA did the same thing, but only with one of the sticks of DDR), I had a bad OCZ ModXtreme 750watt I had to replace because OCZ insisted nothing was wrong with it, I originally went against you fella's better judgment and bought a MSI Gaming 290x and it hits 87c in FarCry 3 with no overclock (returned and replaced with this card that wont take a 50mhz memory overclock), and my 3570k crashes with 4.4 ghz @ 1.32v @ 60-ish celcius after 20 minutes of prime95.
