Can't seem to get past 1.216v on this card.

 

Enabled the dip switches but to no avail.

Tried several ABX editions but voltage is always stuck at +0.200.

 

Ideas?

 

Drivers, skill? :)

I tried the 2.10 MOA edition and it gives 1.6v but doesn't apply it.

Used a multimeter to confirm.

 

Does all the switches have to be at the ON position?

Did you switched to LN2 BIOS ?

I didn't have lightning X version , but it should be same as 1.5GB. First double switch from right should boost vGPU and vMem 0.1 Volt, try them. Did you measure voltage with multimeter under gpu load ? Turn all switches On but don't stay on full load for long time.

 

Southerner switch (near PCI-E slot) is for cold-bug , I don't think that should be necessary to be On. (Num 1 = on : -80C , Num 1+2 = on : -180C)

There is an LN² bios on the card, but I get the CB at -75°.

 

I can use the same bios as on the 1.5GB version?
