I moved this post because I modified the BIOS (sorry about that). I ended up checking out Dante's tweaks and think through his help we've isolated the Super Throttle Bug! I was able to get a couple of successful runs in 4K without seeing the issue!
As you know I've been keeping the 980Ti BIOS' in "BETA" until the STB issue was resolved, which I thought would require a new BIOS from Gigabyte but in fact a solution was found. Thanks Dante for this tip. We know it had to do with voltage and there was CLUE here the whole time that now makes sense.. We noticed that with GM200 the voltage defined in the BIOS is actually one step lower than what you would actually see under load. For example, V5BETA is configured for 1.262v in the BIOS but actual voltage under load will be 1.268v (the next voltage tick). We thought it was strange but didn't think too much more about it. Well finally the adjustment to the upper voltage sliders that corrects the STB is also ONE VOLTAGE TICK off so there is the correlation of the voltages.
This means folks that this BIOS is possibly a MUMOD candidate if all tests well UPDATE:V5BETA AIR BIOS
for Gigabyte GTX 980Ti G1
V5BETA_DP_AIR_1.268v.zip 152k .zip file
This is the F4, DP BIOS
What's new in this version?
is identical to V4BETAF4 with the exception of the 2nd voltage slider
, upper VOLTAGE TABLE
and MAXIMUM VOLTAGE
✿► Maximum voltage has been increased to 1.268v
(1.262v in BIOS). V4BETAF4 is 1.237v
✿► Super Throttle Bug squashedGOALS OF THIS TEST
Since many of you are looking for more overclocking headroom
(some of you even trying the H2O BIOS on AIR, NOT recommended
) I wanted to provide a version of this BIOS that may
allow some additional overclock headroom but still be a viable AIR BIOS (knowing that GM200 is a BIG and HOT GPU).
The voltage for the AIR BIOS V4BETAF4 is 1.237v. The voltage for the H2O BIOS is 1.281v. This new V5BETA lands right in the middle with 1.268v.
(1) To verify if
the additional voltage provides any additional overclocking headroom
(2) To monitor and compare
temperatures from V4BETAF4 to V5BETA
As always, BOTH Power% and Voltage sliders in your fav overclocking app MUST be maxxed out for overclocking.
a custom fan curve is mandatory, STOCK isn't good enough for a MOD BIOS
WHO can flash this BIOS directly?A.>
This is an F4 BIOS. It is compatible with Gigabyte GTX 980Ti G1's with an F3 or F4 BIOS. It is also the DP BIOS (vs the DD BIOS). You MUST have the DP BIOS active to flash this directly.Q.>
HOW can I test if my 980Ti G1 is an F10 card and/or I have the DD BIOS active?A.>
Just extract YOUR BIOS and open 2 copies of maxwell BIOS tweaker side by side one with this BIOS and the other with yours. Copy ALL settings from ALL TABS identically. Triple check! Use TAB and ARROW KEYS to adjust the values more easily.
