Sajin,

Last night, I tried playing Tomb Raider and the performance was phenomenal with SMAA - was hitting 70 FPS @ 5160x2560 with everything maxed out and was using close to 4GB of VRAM!

The only thing was that my top card is usually the hottest card and it went to around 85C after a while. The BIOS1.rom that I used has a power target of 150%. I used a MAX of 110% to get my perfectly stable OC of 1176Mhz across all 4 Titan SCs.

The issue with that, of course, is a 110% power target automatically sets a temp target of 83C which is quite low.

My first question is, is there a way to de-link the power target and temp target so that I can set the temp "max" to say, 90C? This is because once the card hit 83C, it throttled! The other three Titans were below 80C and so they didn't throttle even once. When the temps are below 83C, there is NO throttling which is great. Yet, once that temp limit is reached, it does throttle.

The second question is, is there a way to get the same BIOS (100% fan, 1202Mhz boost, 1.212V) with a lower max power target? Say 115% or even 120%? This way, it would allow the temp target to be around 95C (106% = 95C w/ stock BIOS).

Please help!

I think it is about time that EVGA releases a "official" modded bios with no throttling, higher power target, higher wattage and what ever else has been changed.

Of course that would likely violate EVGA and Nvidia's warranty agreement. Not going to happen folks. Nvidia has started locking down their GPU's more tightly since the 500 series. Yes, it's a bummer for those who like skirting with releasing the 'magic smoke' from their GPU's. It's purely a profit driven move from a profit making corp. Where they decide to draw the line is where customer dissatisfaction reduces profit. I think with the way these have been apparently flying off the shelves, they have made the calculation. It has been ever thus. I'm sure there will be some minor tweaking with the drivers for throttling issues...maybe even a BIOS rev to tweak power states. But don't expect a Nvidia approved unlocked BIOS.

I have been on 17 different bioses, 14 edited myself, several before finding naennons bios trying to fix my severe throttling.

On my stock bios, my SC titan throttled horribly to near stock on several benchmarks, and on parts of far cry 3, despite being on water with backplate, and temps never above 35C.  Not what I paid for.  Editing the power limits on my own bios, was nearly useless, as the card ignored the original buggy bios, hence it ignored the changes.

Naennons bios has something different which allows the cards to actually follow the set power limits in the bios, ie his bios works as intended instead of being bugged like most.

The card has a hard limit of 300W, beyond that it will throttle no matter what.  Naennons bios set default power at 260W (first throttling point) and max at 300W (no point in setting higher than 300W as that is hard max).  This resolved 90% of my throttling (my card is leaky and power hungry) but most cards it resolved all throttling in normal benchmarks.  I had to alter Naennons default power to 285W to stop all throttling using common 3dmark benchmarks/games on mine.  Now only if go above 285W will I start to get throttling, no sensible 3D benchmark or current game have I seen throttling now.

Also I altered the 1398 max boost down to 1202.  But that was unnecessary, the 1398 max boost is ignored anyways since boost table only goes to 1202, but it bothered my OCD.  Interestingly, my stock bios had 1254 for boost limit.  Only other change is I reset base/boost clock to my stock SC settings.

My SC titan is now rock stable at 1202 core boost limit, all I really did was use naennons bios to fix power bug, so the card will actually follow the bios set limits.  

But it isnt without issues, although minor, and I have 2 options.

Option 1) I can use my edit of naennons bios and card works great, 100% stable in many loops now of several 3dmark benches, and gaming far cry3 etc.., no throttling at all,  only down side is my boost will always be to 1202core in everything with more than 20% load on cpu with 1.21v (any game or 3d bench).  (it is 1.21v that is issue, but that seems to be the default or it is the default with this buggy bios).

Option 2) I can use same bios, with P0 and P2 volts changed to 1.87v (or whatever I want), and mhz set to whatever I want.  But to do so, have to always run precision X, and hit default mhz and hit reset apply on voltage, and then have it always running.  Because otherwise the bios setting are IGNORED by the card...not a huge deal, but kinda funny I have to use software to tell the stupid card to follow what I set in bios.

Bottom line, nvidia, driver fixes aside, better release a non buggy bios in future that we can flash to.  Though I am now happy with my card...just not the bios.

I have successfully pulled over the 300w hard max using BIOS1 without throttling.

Depending upon how you've modified your power control, 123% is about 300 watts.

Here is the link to "Basha's bios" lol http://www.overclock.net/...n-owners-club/5500_100

Please let us know how it goes. I will be using the same and will share how these work. 
+1 for your persistence Basha and of course thanks to Naennon for sharing. 
I find it comically amusing when people get miserly about not sharing their tweaked bios, even if they aren't the original author.  

Well, I flashed the "baasha.rom" BIOS and the only difference is that the Power Target is 120% and not 150%.

I am now stable @ 1176Mhz and +300 Mem across all 4 Titan SCs.

There are a couple of issues though.

Even before I flashed the new "baasha.rom" BIOS, I tried de-linking the Power Target and Temp Target as Sajin suggested. The moment I did that, the cards started throttling in various games.

I then tried going back to the "linked" state and even then, there was throttling on the cards. I have no idea why/how this happened. Usually, there was no throttling until the temp target was reached. After I tried de-linking, it started throttling at ~ 70C which is ridiculous.

So, I went ahead and flashed to the "baasha.rom" BIOS. I also reinstalled the 314.21 Beta drivers just to be sure (did a clean install, Driver Fusion etc.). For the most part, there was no throttling. I left it in the linked state since the temp target now was 87C since the max Power Target is 120%.

Yet, after a while of gaming, the cards started to throttle again!

For instance, in BF3, I would play for about 15 minutes when all 4 cards are at 1176Mhz. Then, the cards throttle and go to 876Mhz, or 9XXMhz. I would have to Alt+Tab and then get back into the game and then everything is back to 1176Mhz. Then, after about 30 minutes, the throttling starts again, only to repeat the Alt+Tab cycle to get back the 1176Mhz.

So at times, I'm playing at 9XXMhz @ 1.212V which is ridiculous and what's worse is that the cards throttle.

I am really ticked off about this. Everything was working great @ 1176Mhz until I clicked that stupid "link" feature. Everything went to hell in a hand basket the moment I did that. I am now on the WHQL drivers (314.22) and the issue remains. I even uninstalled EVGA PrecisionX before the WHQL driver install to see if that would rectify the issue. No bite.

Can someone please help?!?!?! I really want to just have my "old" 1176Mhz OC with no throttling back!
