Hello all, new poster....
So, I'm no overclocker by any means, however I would like to get a decently stable setup for gaming. Recently got 2 980Ti Kingpins running in SLI on a RVE, and found that out of the box, the cards are unstable in everything. BF4, Project Cars, 3DMark, etc. It would crash the driver with the infamous get_device_hung. I assume this is a Vdroop issue. So I started running PX to take a look, and added additional voltage + 55Mhz on the clock and +100Mhz power target 133% on the stock BIOS position. OC Bios will give me 150% power target, which I don't think I need.

Boosts to 1481 stable in all games and benchmarks but will always throttle down to 1430 or so upon hitting 60+ C. I don't mind the throttling so much, and I'd be happy to run these cards at 1430 all day long in SLI so long as they remain stable. I know these cards are already overclocked out of the box, and I know what you will all say, that I wasted money on KPE cards, but honestly, it's my money and I like the looks. I've ordered the waterblocks and parts to put them in a loop, in order to keep temps down, but my main reason for posting here, is can I flash these cards with a moderate OC so that I will never have to use PrecisionX or other software to keep them stable? I hate stuff running in the background and just want a rock solid stable gaming and video editing platform. Before I risk flashing the cards, will a BIOS with a slight bump in voltage keep my cards running without DX crashes?

ASIC on card 1 is 83.1%
ASIC on card 2 is 83.3%

I'm using a decent power supply (EVGA Platinum P2 1200) and I found I was drawing close to 1100 watts on the OC BIOS and 155% power target. I've checked the Kingpin cooling forums for an answer but have not found anything other than people relying on PrecisionX to overvolt the card. Seems almost a necessity. I want to be able to run stable and not run benchmarks all the time as I have no need. I want good performance but already getting that at 1440p and 1480 clocks. Just tired of having crashes as soon as I disable PrecisionX.

Please realize, I know already that these cards are meant for LN2 and serious benchmarking, and wasted on a noob like me, but I like the cards and know they will do way more than I'm inclined to do at this time. (and they fit my build theme)

So anyhow, will a modded BIOS yield me stability without having to use external software?

Thanks for your time


Hey bud... well the first thing you need to master is the voltage control on that card.. I think you need software that will be able to address the voltage controller. Precision-X may do this and may be all you need but I really don't know. By default I think your GPU is voltage locked until you open it up.

To answer your question, yes I think a MOD BIOS could help but in your case it will be a combination of a mod BIOS, an O/C app and possibly other separate software that will allow you to unlock voltage.

I wish I could help more, not an EVGA guy here...

...but what I do know is :

(1) You better be getting more than 1500Mhz BOOST *STABLE* for the price you paid for those cards (and yea, you totally did waste your money but you know that tongue.gif ). Overclock each GPU one at a time to learn it's limits. Having the same ASIC% is nice but that doesn't mean both cards will overclock the same...

(2) Once you get a water block installed the cards will perform a lot better. You will definitely see a difference and right now putting a GM200 under water is ideal. You can run this 24/7 unlike LN2...If either is an overclocking 'dud' you want to know this NOW before you slap a block on.

Thanks for the reply, and it is as I expected. Surely I will overclock them more if able, but temps are creeping up considerably. One funny thing I noticed, with 85mV added, at 1481 boost I would reach temps in the mid 80's, however pushing them to 1550 or thereabouts actually decreased my temps by 10c on one card and 5c on another. Perhaps the voltage is actually being utilized at the higher clocks and not wasted as heat. I'm still running these on air/stock coolers.

However found another somewhat "hidden" feature included in the cards, and that is the dip switches that supply additional 25mV to any setting in hardware, and decided to disable PX+reboot and try some games for stability. So far so good, no crashes, and no additional overclocking on the OC BIOS position. So the cards are boosting in SLI at 1430 with decent temps (mid 60c) and are stable. Firestrike is yielding *ok scores at this "stock" frequency of 1430Mhz of 24,478 and Unigine Valley benchmark at extreme settings/1440p are stable. This is without an external overclock or additional voltage modifier, so the 24/7 setup is good to go now I believe. I don't know if there is any throttling going on yet, but I'll run HW Monitor next time to see. (remember I'm trying to avoid running PX or AB for everyday computing)

Now when I want to actually overclock for benches I'll fire up PrecisionX and tweak the settings, hopefully I don't have to add additional voltage to reach 1500 core. Temps however are still holding me back and I will wait for them to be under water before I really push them.



Thanks for the tips, and for bearing with me as I am actually fairly new to overclocking. I wanted to build myself the best rig I could afford, and being that I'm in Afghanistan at the moment, I don't have the tools or resources at my disposal to be constantly tweaking stuff. I realized I should have gone with the Classifieds or maybe even vanilla reference cards, but what the heck. You only live once, and I "liked" the Kingpin cards. Couldn't pass up the fact they were actually available, and I ordered 2 of the 72%+ binned cards. I was happy to see they were actually 83 percenters. :-)

Thanks wasn't aware of the switches. Yah GM200 is screaming for a water block, it is a very hot GPU due to size. A custom fan curve and supplemental fans are needed to push these cards. Good luck!

IMO, I would sell those cards for whatever you can get for them (since they have a high ASIC) and just buy Gigabyte 980Ti G1s and get EK full cover blocks for them.

that's a k|ngp|n; made for LN2 benching. smile.gif

I wonder if anyone has been able to get their GTX970 Strix unlocked using this method. It seems I'm getting crashing if I use KBT then MBT with my bios... I'll see additional sliders in KBT, mod the bios, save, then use MBT to finish it off. Still locks up for me with no voltage bump...

This is for a BIOS unlock to reveal missing sliders that are needed to properly MOD the BIOS. It is not going to unlock voltage on a Strix unfortunately. They are locked @ 1.212v (horribly low) and I've heard there is some software that can be used to communicate with the voltage controller and increase the voltage until you reboot. You would have to search for that specific info.

Good luck

1,21 is not horribly low . more is not worth

Hi guys. I want to thanks all the people involved with thos project! Seriously it give my GPU a big boost and a stable OC!! Only thing that i am concerned a bout is the max boost voltage and my temps. Here is the BIOS i have been taking to flash into my card.

GIGABYTE WF3OC FB0/034E GTX 980 Ti WF3
GigabyteGTX980TiD_PFB0034e.zip 146k .zip file

It seems the voltage is way to hight because GPUZ shows my card is Perfcap by VRel and VOp. It is stuck at 1.243v. I want to know if someone can teach me to lower the max voltage used to OC my card at a reasonable temperature. As of now, i am get as high as 85C (which is locked in AB) at 100% fan speed while i play Crysis 3 at 4k. I just want it to be at max 1.21-1.22v.

Can anyone help please?
