I only use Win7. That's something i run into at the beginning of my bios "exploration", trying several bioses with different subvendors. I use either the stock or your V2 SC version for the last 3 months or so (although i'll move on to another titan bios which i like)...

OMG, just realized it's been a month... Still waiting for the V3 SC version, it's not only because of the higher default freq, it's the subvendor as well, i do a lot of testing/comparisons between stock and svl7's bios (obviously svl7's wins as the freq goes higher) and i hate to have to reinstall the drivers every time i go back and forth (i own an EVGA SC). Gimme, gimme, gimme!!!

Hey svl7 , any news on the SC V3 edition? (oh yeah, i am ready for it!!!) Thanks in advance!

Thanks svl7 ! I'll wait for the version which is based on the SC. Once is out i will try it to death, i'd love to fine tune the Titan to run as cool and as silent possible when running games that are not demanding at all.

The figures you posted are theoretical. You think in practice that 8 and 6 pin can't provide any more juice? What limits them? The 6/8pin wires themselves? Think about it... Unfortunately i am not able to measure the consumption of the vga alone, i can only measure the the consumption of the whole system and find the relative difference. Not an accurate methodology, works way better for the cpu alone,. Still if you think backwards and take for granted that the absolute limit is the 300W (which i disagree with unless there is a hardware limiter at 300W in the card itself, which again if there is i haven't hit it) then something is very wrong about the TDP readings. If you think that's the case then do the following experiment: 1)Flash your card with the stock bios 2)Set the power to 106% (265W), run an app that does NOT power throttle the card (you might want to set the gpu offset to -100), run it until your gpu temperature is stabilized then check the max TDP reading (lets say that is 95% which translates to 240W) 3)Flash your card with the TI bios 4)Leave the power to 100% (350W), run the same app until your gpu temperature is stabilized then check the max TDP reading. 5)If the actual max reported TDPs are close and both BELOW 265W then chances are the readings are fine. If for instance you got 69% max TDP with the TI bios then that translates to 241.5W which agrees with the reading you got with the stock bios, it's almost dead on so readings look fine. Now If for instance TI bios reports 80% which translates to 280W then you can't trust the readings. My personal experience is that the readings are close (EDIT: except on idle, with the stock bios 2 out of my three Titans were reporting idle power which doesn't make any sense and this i can easily check with a wattometer and compare my system idle with and without the card by using the igpu), but you can try and find it out yourself if you like.

@svl7 Remember this? Well, received the replacement of the replacement of my original Titan (lol, long story short, the #3 Titan). Using your bios (SC V2) this one starts at 1.175V no matter what (and 928Mhz gpu freq as usual). The default max boost and voltage for this card with the stock bios is 1019Mhz at 1.15V. I still don't get it...is the starting/base voltage of your bios independent from the quality of each GPU itself (i.e always 1.137V no matter what) or does each individual GPU dictates the starting/lowest voltage depending on the quality of the chip?

@rage fuury Hey...the prob was not the fact that it was boosting lower than my first one and with higher voltage, that was expected since every chip is different. The issue was that using svl7's SC bios i was not able to set card at 1.137V like with my first one which is odd since it's like the card didn't "honor" the bios...strange but it's already RMA'd anyway, i am getting the (2nd) replacement today... I have seen peak reported TDP at 96% (1163Mhz, 1.1212V, +250 mem, #1 Titan) using the TI bios running Sleeping Dogs loops. The 96% in TI bios translates to 336W peak. I have also seen peek reported TDP at 98% running 3dMark13 Firestrike 1st test loops (don't have the gpu/mem/voltage figures handy at the moment, #2 Titan for sure) which translates to a whooping 343W peak. While i can never be sure because of the lack of precision of my measurements, my killowatt readings seemed to follow the increment of the power consumption/TDP. When it was hitting +340W it almost reminded me my GTX580 at 950Μhz and 1.15V (all other setup exactly the same as then) so i'd say that these figures are not very far from reality. IMHO of course and in my experience...

Hmmm, i'll uninstall/clean install the driver for starters just to see what happens... Like i wrote, not a real prob, just a little bit strange that the card doesn't "honor" the bios settings...

Got my SC Titan replacement on Monday (RMAd for clicking/ticking fan noise) and noticed something interesting... My "original" SC boosted at 1058Mhz using 1.15V, the replacement boosts at 1045Mhz at 1.162V. Nothing strange so far, different cards boost at different freqs and voltages. The strange thing is that with my "original" Titan and the TI bios i had full voltage control all the way from 1.137V (default value at 928Mhz) to 1.212V. With the replacement card and the same bios i can't set the voltage at anything less than 1.162V and 1.162V is the default value for the same 928Mhz. Still i can set it anywhere from 1.162V to 1.212V. Strange though, i thought the 1.137V was kind of "universal" base voltage in this bios...i uninstalled/installed the Precision... I don't remember uninstalling/installing the drivers though but i can't see how this would fix it since i was going back and forth from the stock bios to TI in my first Titan without having reinstall the drivers. I just missed running the card at 928Mhz and 1.137V in not demanding games (like F1 2012 maxed) and keep the card cool and quiet. The Auto-fan in version 2 works great guys...

I have spent hours and hours testing, benching, gaming at every possible freq/voltage/fan combination using this bios, i have kept tons of AB/Precision charts/graphs and i have never experienced any kind of throttling with this or any other high-TDP modded bios. The only throttling you should ever get (with this or any other modded bios) is because of the low temp target/high temps if you forget to increase your fan rpms and/or forget to increase the temp target (which by default is 80C). Apart from that which is 101% normal you should not get any throttling. For instance I spent about 2 hours yesterday playing Metro 2033 (every setting at max), 1 hour Farcry 3 (every setting at max, including MSAAx8) and half an hour Crysis 3 (every setting at max except AA which was SMAAx4) at 1150Mhz/1.175V. Power target to 100% (=350W), temp target 90C. Even with temps around 81-84C - as expected - i didn't get a single step of throttling (kept the Precision graphs) and i am mentioning this because i have read all over the net that we should keep the Titans below 80C no matter what the temp target is. I doubt it, has never happened to my card anyway. Just my 2 cents...

Thanks again Brian, you are right. Testing the new drivers as we speak, they are fine (Farcry 3, Metro LL etc). Yeah, the new Precision is what i use right now, still can't store the voltage per profile but no problem, i can set it manually in 3 seconds. Just for the record, AB beta 10 still can't change the voltage in TI bios, i am mentioning it just in case somebody think that the new version works.

Thank you Brian, no reason for me NOT using the TI bios then!!! Another question, anybody tried the new official Nvidia drivers with the TI bios's? Also the Afterburner 3.0.0 beta 10 is out (new Precision too but i prefer AB's interface for some reason), anybody has tried it with the TI bios? Thanks!

I don't think that's possible, 13Mhz steps are predefined.But i spent some time to "map" the frequency/steps so i don't have to guess every time, this is for the SC TI version so here goes, might be useful for someone: gpu offset actual gpu freq +0 928Mhz +13 941Mhz +26 954Mhz +39 967Mhz +52 980Mhz +65 993Mhz +78 1006Mhz +92 1019Mhz +105 1032Mhz +118 1045Mhz +131 1058Mhz +144 1071Mhz +157 1084Mhz +170 1097Mhz +183 1110Mhz +196 1124Mhz +209 1137Mhz +222 1150Mhz +235 1163Mhz +248 1176Mhz +261 1189Mhz +274 1202Mhz +287 1215Mhz (didn't care for any higher frequency that's why my list stops at 1215Mhz)Also these are all the voltage steps available in the TI SC version 1.137V 1.150V 1.162V 1.175V 1.187V 1.200V 1.212V

Yeap, tested the 2nd (latest) version of the SC TI bios, the auto-fan works fine now, nice one svl7... EDIT: silly question but i just have to...is there any way for a company/dealer to find out what bios is installed in a card if the card is "dead"? (meaning the card doesn't post, no signal, doesn't get recognized by any system in any PCI-E slot and so forth). Just trying to "calculate" the future risk for an 1K card just in case something goes wrong (yes, i hate Murphy's law, lol)

Something is bothering me with all the no-throttle bios's which have higher max TDP than the stock very limited 275W one. I have many cases that the maximum reported TDP reaches and exceeds the 90%, that's 315W. I wonder how safe is this for the card, meaning the pcb, vrms etc, not the gpu chip since the max voltage is 1.212V and i can control the temp to be around 80C. But for instance running the Sleeping Dogs and feeding the card with 1.212V i actually got 96%, that's 336W. 1.187V gave me 315W (90%), 1.175V gave me 305W (87%) and so forth...

Hey @EC51 , still waiting for somebody else to confirm (or not) the AB/voltage issue. I'll never be 101% sure until somebody else try it and post back although my system is 101% fine, i installed/uninstalled several times the AB and the driver (i always do this after a vbios flash just in case, just to be on the safe side). Had the same impression about these progs, thought they were actually almost the same with different skins...interesting...

Thank you sir! I'll try it over the weekend and post back.

Had a non-stop 8 hour OC/stability testing session yesterday with the SC version. Actually i was right, AB beta 9 can't change/set the voltage. No problem with the Precision although it's a shame it doesn't store the voltage setting in the profiles so i have to do it manually every time. Tried the Nvidia Inspector, not going to bother with it, not very handy interface. As expected, no throtle at all no matter the freq, voltage or what i run. Max TDP dunring the tests was 86% if i remember corectlly which translates to a whooping 301W. If this is your first no-throttle bios, watch the temps closely. It's one thing running the card at X frequency at 1.2V and seconds later to have the card running at way lower freq and voltage due to power throttling and another thing to have the card running continuously at these settings. This bios has 1.137V as a starting voltage. While i am not 101% done with testing it seems that my card could be stable at 1084Mhz with 1.137V which is a nice surprise since by default with the stock bios my card boosted to 1058Mhz with 1.15V. No probs at all with idling, downclocked to 2D freq/voltage every signle time as expected. I have a ton of graphs that show the behavior of this bios but i don't know if i should post them in this thread (don't want to mess it up with a bucket of charts) or better create a new one. Once again, nice work @svl7 , whenever you fix the auto-fan curve issue i am sure i'll be the first to download it. EDIT: actually just did a new record lol, max power during running loops 90%, 315W...nice one...

@Brian , ok just realized that you use the Precision X and i keep thinking about my MSI AB/voltage "prob" (quoted because i am not sure it's an actual issue, didn't have the time to play with it yesterday so it might just be a user error). Tell you what guys, i'll flash my Titan with the SC version again today and will test it thoroughly at the weekend. I'll experiment with it, keep graphs (or videos if i am allowed to post them in here) and post them here for everyone else to get the idea about the behavior. Direct comparison to the stock SC bios.

Talking about the stock auto-fan operation here. No it doesn't work like the stock bios, way lower rpms and very slow increasment when the temp climbs up. Again, i am talking ONLY about the auto-fan operation, not the custom curves.

Darn, you are right sir!!! I've read that, i just forgot it! Thank you! Don't worry though, the reason i got back to stock is the auto-fan operation. You see i have two "modes" operating this card (profiles actually). 1st profile is for the games that don't need OC at all (for instance F1 2012 with every setting maxed). For this i just leave the card as it is (max boost 1058Mhz by default), power target to the max value, temp target at around 85-88C and auto fan. 2nd profile is for the games that i need to OC (Crysis 3, Farcry 3 etc) to get the best out of them (AA lover here). In this case i always set manually the fan rpms at a fixed value (70-73%) and that's my 2nd profile. I can live with the performance-noise trade off in this case. I just didn't want to set the rpms manually to a fixed value for the first case and i don't feel like i bother making a custom profile curve at the time being... But i'll try it again for sure, being an ex-Fermi user (skipped the 6xx line) with this bios it feels more like "home" comparing to the Boost mambo jumbo...

Never mind, gave it a quick try so i am answering to myself. Flashed the SC version, so under full load it boosts at 928Mhz with 1.137V if i remember correctly. Then all i have to do is to just add the right gpu offset to get the wanted frequency under load. Very Fermi-style, i dig it, nice work. Flashed back the stock bios though, something is wrong with the way the Auto fan works. Also when i set +13mv (MSI Afterburner beta 9) the voltage remained 1.137V while i am pretty sure it should be 1.15V, played with OC and voltage only for a few minutes so don't quote me on this (i always reinstall both the driver and the AB after a flash no matter if it's needed or not, just in case). No throttling whatsoever (best way to test for me is 3dmark11 1st test, even at the stock boost i was getting throtle/downclocking), nice work, i'll give it a try again in the future for sure.

Hi, first post here, just yet another Titan owner who would love a bios that only increases the max TDP while everything else remains intact. So first of all i'd like to thank svl7 for his work and 5150 Joker who keeps giving useful infos and all the others that have posted feedback. Now, since i am not thrilled flashing bios's just to test them i have a few questions, just to be sure that this version is exactly what i need. I own an EVGA SC. My card -voltage-wise- behaves like this (all settings stock): [email protected] (idle) [email protected] [email protected] [email protected] (max boost out of the box without touching anything) If i flash the SC version of svl7's bios, will this behavior (freq/voltage) continue to be the same? I like the way it operates just as it is minus the throttling so i'd love to preserve this bahavior just minus the bloody TDP throttling. Also, in order to avoid throttling will i have to keep the temp under a specific temperature other than the temp target i select? Thanks in advance.
