Thats about all you can do without doing a hardware mod. Really the bios wasnt needed since you can get the extra voltage without it. 1.200 stock, 1.212v by clicking the extra volt option on the gpu tuner software. 1300mhz+ is really good.

I actually did all my bios modding and flashing for my 660 using kbt 1.25, but I wasn't sure if it was compatible with the 700 series so I downloaded 1.27 but the interface was much more confusing than 1.25 with all the power options, so I went ahead and let Cyclops unlock my voltage and power for me since I didn't want to risk screwing up the bios.

Kbt reports my voltage at 1.212 and power at 300.

I went ahead and downloaded MSI AB 3 beta 19 (was using the latest final version prior to this, I think it was 2.3.1) and now my voltage can be scaled to 1.212 thumb.gif (actually, it won't let me set my voltage to anything in between, it's either default voltage or straight to 1.212v.

However, my power limit is still stuck at 111%. It won't let me go up to 150%. Any ideas?

if he did your bios like i do them  you are probably at 140% power limit. he probably did it in the bios so you dont have to adjust it.

Oh yeah, I completely forgot about that. doh.gif

I just checked the bios again and indeed both the "Def (mW)" and "Max (mW)" are set to 300,000. (I'm assuming Def means default).

But then what happens when I adjust the power limit in AB from 100 to 111? It does nothing?

at 100% you are already at 300w so its pointless to adjust it. as it will do nothing.

Got it, thanks. smile.gif

One more question, on the OSD if the power draw says 90%, does that mean 90% of the original ~200W or 90% of the new 300W limit?

Actually I think its still 90% of the old limit and when it uses more than the original max, it just keeps reading higher. When I mod my bios the percentage never changes from what original was except it will climb higher.

I base that opinion on my experience with high voltage. Say stock bios I think my real max voltage before it throttled was 1.400v, well modding the bios but still leaving the power target at 110% (max on asus at least) I still throttled, it wasnt until I went higher in percentage that the voltage wouldnt throttle.

Honestly modding the power target will not do anything for you unless your maxing out the stock limit with the voltage you already have. Thats my experience on 2 gtx770's and 2 gtx670s.


edit:

I think the only exception MIGHT be is you mess with the middle number and not the peak one. Still though, unless your maxing the stock power target, there isnt a need for more. Currently I am on 1.33v on the stock bios and peak around 90% on bf4 BUT each gpu core will pull a different amount so someone else might need a modded bios for even 1.25v

in this case it is the new number as the tdp default value has been changed so it reads what the default value is and calculates based off that number. i never increase the power limit without the tdp and always increase the default value as i dont want to leave it to a oc software to apply the voltage lift.

This was as far as I could get without BIOS mod.






Anything thing more that +50 on GPU clock crashes and the max memory clock I went was +793MHz but it was a little unstable. so I dropped it down to +746
