Hi guys. So i decided to unlock my gpu bios. So i went to GPUz and i exported my bios and unlocked it after that. So here is the tricky part , when i try to flash the bios it says something like "Hierarchy mismatch" and it cancels everything. So how ca I solve this? Any help is much appreciated

I know but isn't it possible to do it with the 690 , I mean if you can't do a simple bios flash what can you do?
I have no interest in GPU boost 2.0 I want the 150% power target and 1150-1200mhz boost (When I unlock it it says max boost speed 1203mhz which would be really nice if it can really happen).

i believe that is what boost 2.0 does. it gives the card the ability to work at higher MHz since it dynamically reads the current load and thermal overhead giving you that extra MHz. what do you use to see your speed info. the newer 7xx series cards boost beyond what you set msi AB or precision x because of the boost 2.0. read some gtx 760 reviews where they overclock.
to manually set limits and things you would probably need to learn about hex editors and load up your bios into that and spend some time learning. I do it with my AMD card but it is not for the faint of heart and if you do not have a dual bios card you can brick your card and warranties are voided upon flashing of the bios, fyi. the link i sent are the only info i have seen on others doing the work of bios modding.

Yea I know what gpu boost does I'm not that much of a noob. I want to do the bios flash because my card can't OC for s**t and I'm playing crysis 3 with dowsampling from 1440p to 1080p and if I oc my card more then 50mhz on the core it crashes the drivers after 10 seconds in the game and resets to default. It's not overheating or anything with my custom fan curve It can't get to 70C. Thats really annoying because i see people with 100+ mhz OC that run stable and I got a crap card.

my 690 runs crysis 3 at 2560x1440 at a minimum of 44fps and avg of 50-60. I want it to not drop under 50. Don't get me wrong I'm very happy with the 690 but I would like to get a bit more from it. Note that i only use fxaa , but who uses MSAA on 1440p?

even on a 4k screen the msaa or txaa still has the benefits of really making some textures sharper from what i have read. I overclock everything in my system just so you know. I even pushed a reference gtx 560 into the top10 using 3dmark
is your memory overclocked at all. if it is you can try turning that down and that may give you a little more headroom for your GPU. It does not do much but sometimes it will give you a little more.

Another thing i learned from overclocking for days straight is that there is a real fine line between best core speeds and best fps in actual games. I know you can automatically go to some of the most difficult areas in crysis 3 through a console command and the best bet for you may be to just sit around for an entire day (like I do) and just keep tweaking and seeing what happens in game.

maybe find a good GPU OC then start moving up on the GDDR MHZ and see what it does for ingame playing. when you stop seeing an improvement ingame then stop there and use the rest for core clock.

I have not observed your precision x monitoring graphs so I do not know if you are staying pegged at your power limit or not. I am pretty sure that all throttling starts at 70C so maybe while you are playing cank that fan up a little more to make sure you stay in the 60'sC
I am going to keep looking for a way to manually modify your power limit to see if maybe you can get to that 400watt power usage rating

you obviosly like the super high end equipment and appreciate what it gives you so this article may be of interest to you it will not help your current situation but it is awesome to see this stuff coming around
tri-titan on a 4k screen @ 60Hz. this is the first of teh 60Hz monitors.

My goal is 80mhz more on the core and 90 mhz on the memory, I can do 50mhz core and 90 memory easy and my fan is cranked up alot as soon as i hit 55C it's set to go to 75% and at 65 it's at 90 so temps are not a problem for me. I read yesterday that one guy fixed his problem by setting his voltage to be at the constant max when under load but gpu voltages scare me since I broke my first gaming gpu (a gtx 460) with overvolting. I know that you can't really OV the 600 series but I'm still scared to crank that voltage manually.

The article is great. I'm really happy to see the 4k monitor, maybe when the 800 series comes out a quad SLI gtx 880 pared with that monitor would be a really awesome experience. Although the monitor is really expensive hope the prices drop till then and I have the money for the rig and the monitor. I've seen a guy playing in 4k with 3x titans and performance was really bad 30-38fps, I really can't play with fps in the 30's.

in theory we could have gamed at 30fps since the other 4k monitors were only 30Hz but yes 60fps is a much improved experience. I expect everything to come down in price very quickly. Hell 1440p monitors are getting in the $300's now.

I always bump my voltage up a little if needed. i think since the 5xx series they have had safe voltage control on cards. I would try a little extra voltage if it would help (it almost always does).

in that 4k link i watched that whole 45+ minute video and they were actually getting some pretty good fps. they were saying that they had to use alpha drivers so I expect things to improve allot on that front but we wil see. It is nice seeing the 386 bit memory interface being maxed out by single screen resolution already tho. I have watched 3 different 4k screens now in person and even when the programming is of a little girl dancing through the flowering field (which is awkward to watch in public) it is just mesmerizing in its depth and colr reproduction. I swear it looks better on tv than in real life. single blades of grass with dew on them are just amazing. hopefully those types of rigs come down in price .

Yea it would be amazing to play next gen titles on 4k with everything cranked up with 60fps. Imagine how games like Battlefield 4, Crysis 3 and the witcher 3 would look. As for voltage I'll try getting it to it's highest and se what happens but still I wont keep it oc all the time just if I get under 60fps in 1440p which for now happens only in crysis . I didn't realize that the 690 was so powerfull, at first I thought that I'll be lucky to get 20-30 fps in crysis 3 instead I got a min of 44.

Just took a look at the voltage and I see it goes to just 1150mV but the card under stress test normally runs at 1174mV so if I set it to 1150 will it help at all? I mean if i set it to 1150 i wont drop under it and will still boost to 1174, right?

if it did not it would be a driver issue so yes it still should. we all know computers tho so without actually play testing it with heaven benchmark or something it is always a mystery till it is tried. what i would consider doing it going up to 1185 or something. but I do know that kepler is dynamically controlling all watts and volts determined by thermals so I do not know how much changing voltage will do.

the problem with the above is that keplers are voltage locked and there is only one way that I have discovered to fix that.
this will void your warranty and you will get another 100MHz or so.

I have not read that whole post and i would recommend that you do before trying this. I have done my own bios editing and it is risky and I have bricked my card before. I had to use the integrated graphics and reload the original bios to fix things but I have always recovered(soft bricking). It is a really tough call and only one you can make.

Yes thats the unlocked bios but my card won't allow me to flash my bios and i can't do 1185 without flashing the bios manually I can do 1150 and the card is soposed to run 1174 so I don't have much hope of doing nothing until i flash the bios. Another thing is that GPU-Z doesn't allow me to save the bios from gpu 2 to a rom file, it says that it can't read bios from that gpu.

I don't know how to use a hex editor since I've never used it before , but the judging from the nubers they are the same thing. So if I dl and unlock them what difference would it make? It still probably won't let me flash them. One more thing, on the 600 series is gpu 2 the master gpu? Because on the older 500 series it was gpu 1.

in all my reading so far I have not come across which is the master GPU. I still have many tabs open i will see if I had missed that.

as far as a hex editor you would not have to know what you are looking at so much as you would just want to compare numbers.

above is a free hex editor and I think it is always a good idea to see what these things look like so you get a better idea of how it works and what they do just for a broader sence of how things a functioning

the link below is a tutorial of sorts that shows a manual bios editting for my series of cards. this link taught me allot and I have read it probably 100 times to just a basic understanding of things
http://translate.google.by/translate?sl=ru&tl=en&prev=_t&hl=ru&ie=UTF-8&eotf=1&u=http://people.overclockers.ru/test2013/17506/Upravlyaem_napryazheniem_videokart_AMD_HD_7_serii_cherez_redaktirovanie_BIOS

if you downloaded them then edited them you should be able flash them.
if you have tried to flash them and it did not work have you used the-unlockbios command. so cards have an extra layer of flash protection that has to be undone first.

So as I am writing I am thinking how to find out which GPU is the primary. I would turn on vsync and run a heaven benchmark which i would think you can run over 60fps. in this scenario if you run hwifo64 you will probably see that one GPU is taking more of the load than the other and I would surmise that the more heavily used GPU is the primary.

Just tried a game that doesn't use SLI and gpu 2 was used only. In game usually GPU 1 clock's a bit higher than gpu 2 but is seems that gpu 2 i primary since it's used by the game that doesn't support SLI. So now what I dl the 2 bios files unlock them, flash gpu 2 first I suppose then gpu 1 with the unlocked bios and thats it? I used a command that must remove the protection the first time i tried this but didn't do anything.

Just tried the same with the DL bios. Still gives me an error.

Tried other commands now I get a different error.

UPDATE:
I read a forum where a guy had a similar problem and he fixed by following these instructions someone posted.
Two methods to force a flash:
nvflash -p -u -2 Insert ROM NAME.rom

Nvflash -e

then DO NOT REBOOT but then enter the command...

nvflash -p -u -f Insert ROM NAME.rom


I don't know whether they will work or not, I just copied info I found at xtreme.

These were performed on NVflash 4.42

He had this problem on a 6800 GT. That was a 8 year old post so will it work for me?
