Finally got my bios mod (G1 Gaming F51 modded to MUMOD v1.1) and happy with the results, rocking at 1551/8000! specool.gif

Her you can find all of my "default" oc (1531/7000) and extra oc benchmarks: smile.gif

http://www.overclock.net/t/1544574/gigabyte-gtx-9xx-g1-gaming-h2o-air-bios-tweaking/2260

Took me a lot of time to do all these stability tests, still need to intensively test in gaming (if I could only find all of the time to dedicate) tongue.gif

Btw:
whaddya think? I'm fine at 1551/8000? Does it make any sense to continue with the mem oc (hynix on my 980)?
Talking about the mem oc cause the gpu, won't increase any score (in most of the benchmarks I've tested) on the higher (1571) gpu oc.
We're getting pretty much of its (architecture) limits?

I've noticed a definite improvement in gaming FPS when upping my Memory Clock by +250 for a total of 8000 MHz but never bothered trying anything higher. I find that raising my Core Clock gives me more performance increase than the Memory Clock so I focus mainly on how high I can get my Core Clock without wasting my TDP limit on my Memory Clock. Let me know what you find. I'd be interested in seeing your results. I've had my Core Clock as high as 1620 MHz with a modded VBIOS but I only did that for a few benchmarks before I reflashed back to stock. I get really good FPS in every game running at 1500 MHz Core and 8000 MHz Memory. Right now I have SLI disabled and still average 175 FPS in BF3 with all video settings at their maximum.

Is there any mods that one can do to the 980 to remove some of the power saving in Maxwell? Like to the bios or the board itself? I have been getting some slight stutter in every game I've played and have tried just about everything in the book. I have read about the Maxwell based GPU power savings and stuttering possibly due to it.

There is always a way!

Read this to learn how to do the flash. The video is short and on point.
http://www.overclock.net/t/1573308/nvidia-gtx-900-cards-custom-bios-upon-request

And read this to learn how to mod your BIOS:
http://www.overclock.net/t/1522651/disable-boost-and-bake-in-max-game-stable-clocks-for-maxwell


My 980 @ 1500/8100Mhz is such an improvement over stock clocks. Best modification of my rig hands down was the BIOS (Flashed BIOS>Delidded CPU) tongue.gif.
GPU also runs 1500Mhz constantly under any 3D load which helps stop the stuttering. (clocking from say 1000 to1300Mhz makes a tad of stutter)


I'm assuming you OC your CPU too.
You can disable SpeedStepping while enabling C-States to force a constant clock speed but still scale the voltage according to load. (at idle I'm at 4.5Ghz with 0.000v)
Forcing a clock like this helps quite a bit when the CPU load fluctuates alot. (gaming)

I wouldn't recommend running your video board with the clocks locked at max all of the time. This VBIOS looks promising but I haven't personally tried it yet:

The Power Limits and Voltage have been increased and easily adjusted to your liking using MSI Afterburner.

What's wrong with that BIOS? Why would you need something different?

Here is a thread where you can ask to have your BIOS modded: http://www.overclock.net/t/1573308/nvidia-gtx-900-cards-custom-bios-upon-request
