Hi 8pack,

I have a 980 HOF, i pushed it to max on air, but the card maybe locked by firmware, i can bench 1550/2100+ with 1.21v on gpu (controled with dmm), default vgpu 1.25v. I have better stability with lower voltage.

Adding more voltage (over 1.25v) result crash, i do not wan't to push the vgpu over 1.38v, just unlock that limit on power, bios edit change nothing.

Just for benching on air (maybe water, but not now)

Do you have any information for a futur public update? Or simple solution can help me?

Thanks
 
On air full fan 55° on bench (firestrike/extreme/ultra), waterblock can help me?
Maybe the gpu don't pass 50° but it's not a big difference.

I don't understand, asus/evga/gigabyte/msi, many good 980 over 1600 on air and over 1700 on water but no HOF.

What is the difference with the stock bios and 9A bios? Just unlock voltage?

Sorry, 9A is on the name of the bios, 9A = bios A2.
Mine can do 1550 with 1.195v (check with dmm) and some times 1566 but adding voltage cause crash.

Can you share the A2 or A2-1 bios just for check difference?
I checked on many forum and no one bench on air over 1600.
 
New test today with multiple bios modded by me, and always the same story, need waterblock and XOC bios for more.

And after many search, no one can pass 1600 on air with 980 HOF.
On water, found just one, but the waterblock are very rare.
 
I understand that, i send mail to galax for bios and tool and no response.
On water, maybe i can make better oc but little gain.

XOC tools is just NVVDD with more options?
You cannot share bios, but can you show me on email screenshots of that bios?

Today if i can, i make other test with modified bios.
Another question, on the card, under backplate, i have the 3 little switch, this is for ocp nvp unlock?
