** AMD R290X NOW AVAILABLE & OVERCLOCKING REVIEW!! **
- Thread starter Gibbo
- Start date
Permabanned
Gibbo bit shame o well cards just came out so will be some interesting stuff going off with it 
1000mhz with 1.2 would be perfect for standard cooler and drop temperatures by 10c i bet.
Orangey Whining ?? I used to have 6x80mm fans running at 12v on daily basics for like a year
Now i got Asus headset with noise cancellation this will help. Love it flip the switch and dont give a crap about anything haha

Just to confirm something you pointed out already, presumably if you flash the ASUS bios on any other 290X you basically have the same card because they are all reference anyway?
Yes.

**UNDER-VOLTING**
Guys it seems the current drivers / BIOS have protection built in so the card won't allow you to under-volt it by any usable amount unfortunately.
Anything below 1225mv seems to trigger protection meaning it won't load to windows desktop until you do a full power off and on.
However going from 1250mv down to 1225mv has reduced temperature by 5c under-load with no ill-effect on stability at stock speeds with the card still set at +50 power with 1000Mhz core speed always.
If this protection gets removed by later drivers/BIOS the card in theory should be able to run fine around 1150-1200mv which should be good for a good 10c+ reduction in temps over stock. Seems you can get them to run pretty cool.
Infact its turning out to be quite a fun card for the tweaker/overclocker.
Sounds like it should OC well on stock volts.
What sort of OCs have you got up to with the voltage tweak cards?
1250MHz seems the peak for the core.
6800MHz for the RAM.
On absolute best.
Most seem to do 1175-1200 and 6400 happily, need a good card to get the extreme levels.

Gibbo, was your benching done on Air and what volts did you put through the card?
Caporegime
17.5-25% overclocking headroom on the core is good and is about the same as 7970, give or take.
Stock cooler and MK26, which is air. 1410mv is max, stock is 1250mv, I used max.

Thumbs up for the ground work

Guru3d running the "leak" story too;

Good to get the OCUK name out there
Caporegime
Thanks.
Caporegime
I bet most will run 1.1v at stock or a little more, reduce power consumption and heat.
Caporegime
Doubt it. 1.2v-1.225v minimum, if they're low asic cards as i expect.
Caporegime
Early GPU's you might be right.

Edit: moving question to a more relevant thread.

Will a i5 2500k bottleneck a 290x?
