GPU Tweak shows the same thing. However like I said before, this is without a heavy and varying load.

While gaming, the lowest I have seen the voltage drop by is 80mv.

In that way, the screenshot you see (which was set by 'force constant voltage' in AB), is almost never seen while gaming due to vdroop. The voltage is usually between 1.22 to 1.25.

If there was a way to consistently achieve 1.277v while gaming on this card I would be very happy... I think Matrix cards can adjust vdroop, but AFIK DC2T's cannot.

Anyone that has a 280X DirectCU II TOP can you tell me what drivers you are using and whether you have any issues or not? I'm on the latest drivers and still get the odd glitch in League of Legends as well as the thing where whatever is displayed on my monitors will move down vertically for like a split second then go back to normal.

I'm using beta 9.5 for almost 3 weeks now, I haven't had any issues thumb.gif I don't play League of Legends so can't comment on that.

I've had issues with almost all drivers I've tried. Fresh install of Windows too.

Question to MSI 280X owners. Is the card voltage locked, and if that's the case is there a BIOS around that can unlock voltage control? I 've ordered one but if i can't undervolt it i'm going to have to cancel the order.

i had MSI 280X i can tell you it's not locked. it can go to 1300, the default voltage is 1156 in my card. i haven't try to undervolt it... and i don't know why you want to do that, but i can assure you the card is not voltage locked.

look for the bios in here, and match this with your card later, if the last digit is still 331 (or 3XX) instead 435 then you need to update the bios, take it from HERE or you can go to official MSI forum to ask one, either way you will get the same BIOS, i DO try both bios and compare though, it is the same bios.
