I have 2 6+2(8) pin and 2 6pin to 8 pin converter for my PSU question is

[StaticStrength]

Should I use 6+2pin or 2 6 to 8 pin to power my RX 480 if i want to OC.

never use the converters unless you have to, in this case I personally think you definitely should not use the converters.

The thing is currently I have RX 480 Strix and it does fail even at 1360 MHz @1175 voltage, which shouldn't be happening unless I have a really REALLY bad luck. Also is there a way to stop GPU Tweak II to stop 3d OCing? I have 750 80+ Bronze PSU which has 744 W on 12V+ rail.

does your power supply have 2 different cables for pcie? are you already using two different cable to power one card? or are you using a single cable with two heads? also I know you have 744 w on 12v+ rail, how much amperage (A) on it?

I have 2 6+2=8pin cables, currently using 6+2 on my RX480. Amperage on 12+ is 62A.

This is the 6+2pin that i'm talking about. I have minimum 2 of these i think. Not really sure if i have more than 2.

if I'm looking at the asus website right, there are 1 8 head and 1 6 head plugs to power your card.
you should use both of the cables available from psu.
one cable with the 6+2 head on the 8 head and a different cable for the 6 head.

Nope AMD RX 480 Strix has only 1 8 pin slot.

well in that case with one cable you are looking at you already did all you that you can do.
your card just won't oc like you expected. you lost the graphic card oc lottery.
converters won't help.

If i really lost it that means I lost it really bad bc, pretty much everyone was able to OC min of 1350 with stock voltage which is 1150.

 

[Darthutos]

at this point only thing to consider (which is far out there that I don't recommend) buy a new more powerful more efficient power supply?
nota bene I seriously do not recommend this approach and you may waste a lot of money for the same result.

I need to buy a new PSU for my brothers computer anyway, I'm planning on 850 Watt in case of if I want to CF it. Also gonna buy Seasonic M2, it's still 80+ bronze but it has better capacitors etc compared to my Thermaltake SmartPower.

^^ exactly.
Doubt a new PSU will make a difference. ASUS strix is advertised at 1330 mhz in OC mode. If the card runs stable at that speed you got what you paid for. Overclocking is never guaranteed.
