Galax 970 - custom bios to remove +37mv limit?

[PESolution]

Hi all,

As in the title, im hoping to remove the +37mv limit on my galax card, as although the memory can be overclocked like a beast (+570 before it starts to artifact), I can't get the core above +100 stable, which works out at 1464mhz.

This is the card I have for reference

Thanks in advance,

Why Galax limit their cards to 1.212V is beyond me when MSI and Gigabyte go to 1.275V at least. The voltage limitation is the key reason why most 970's are stuck at around the 1470MHz range.

I know people have been flashing other brands bios's, but i just want to know if this is compatible with galax cards too.. and hopefully there is a good and current guide to it..

Also - my card sticks on 1.200v no matter what i change in afterburner when monitoring on GPU-Z ...

Don't flash another brand bios to the Galax - it will brick it.

The 1.21v is a hard limit, custom bioses wont get it higher (I know, I've tried).

Extra voltage doesn't really gain anything on 970's anyway - maybe 10mhz if you're lucky.

i cant get 1.21, only 1.2

Try less voltage, believe it or not the 970 and 980 on air really generally dislike voltage, hence the limits in place.

Both my cars I tested I found upping the voltage really did very little, except generate more heat.

A great card will hit 1600MHz and a poor card 1400MHz, that's silicon lottery.

I can't even drop the voltage Gibbo.. literally nothign happens when i change from 0 to the maximum of +37 on afterburner it just sits locked on 1.2000v on gpu-z

compare this to the above screenshot and you will see no difference :s

I wouldn't worry about is - 0.01v isn't going to make any diff to your overclock.

Its nit the 0.01v, its more the fact it doesnt go up or diwn when i change in afterburner plus or minus 37

 

[stooeh]

Even with custom BIOS I can't get my core above 1.212v (inno3d)

 

[PESolution]

But does it go lower when u reduce it in afterburner?

No - it doesn't on the Galax cards - there is no way of externally controlling the voltages via software.

Strangely enough I found that adding extra voltage increased the clock of my card.

For example with no voltage touching it would boost to say 1450. By changing the voltage to +84 or whatever it was, the card would then boost to 1500.

The voltage shown in MSI afterburner is incorrect. My card shows 1.275v but actually pulls 1.3v when measuring with a multi meter.

thanks for good relevant advice

Presumably there's no hardwise / bios way to change it?

The MSI cards seem to have a 1.275V limit but the Galax has 1.212V. I see no reason to limit the Galax other than to stop it reaching 1500MHz+ to prevent competing against future Nvidia cards I guess.

My ASIC Quality of this card is 64.7% - could this have a bearing on why it's such a bas overclocker? Given that I can't increase the voltage.. and ASIC quality being low meaning the gpu needs more voltage anyway to hit it's normal clocks?

Or am i misinterpreting ASIC quality?

It's doing nearly 1450mhz on the core - I wouldn't call that a bad overclocker! 2000mhz on the mem is also VERY good.

Probably find if you reduce the memory overclock you can increase the core overclock
