Who just said the DC2T was voltage locked Oo ?
I highly doubt that because I used AB and my GPU only crashed at 1250MHz / 1800MHz and was fine @ 1200MHz / 1800 MHz. I would be very surpised if it could pull those clocks off with stock voltages (I didn't do any proper testing though, just FurMark).

And why would EK, out of all these 280X cards, chose to make waterblocks for the DC2T if it was voltage locked ? That simply wouldn't make sense.


Edit: what's this "unofficial OC" I've seen come up several times in the last ten pages ?

I currently own one

The DC2T is unlocked up to 1.3V. And it also works with MSI AB.

However, the temps are not as low as you say. Maybe it's my ambient temperature inside the case (31-33C in idle), but during a BF3 session it goes up to 75C with the fan at 45% (while the motherboard temp sensors says 47C).

In the same case (HAF 922) I have a 2500k @ 4.5GHz with 1.32V and it goes as high as 60-62C.

if you want 1250-1300mhz and 1850mhz oc you should have gone for the matrix -p instead of dcuii top , most of them can do it. and keep the card under 70 with stock cooler.

While we are on the topic of OC
what would you guys consider a "safe" 24/7 OC for a 280x which you plan on keeping ... lets say 2 years ?

Alright so the Asus DC2T 280X is indeed voltage locked on AfterBurner (at least it is on the latest version although it looks otherwise). Here are a couple screenshots showing that the Voltage didn't change although I set it higher in AB:




But this actually makes me happy because that means I've got a pretty good card and will probably be able to fully benefit from putting it under water thumb.gif
edit: unless there is no way of unlocking the voltage :'(
