I need GTX 570 information and BIOS help please!

post #1 of 4
Thread Starter 
Hey guys,

I need some help. I have a PNY GTX 570 XLR8 Enthusiast Edition card and I have unlocked voltage control with MSI Afterburner but now I'm hitting a wall @ 880 MHz. I can get 880 MHz with 1.025v but even if I go up to 1.088v I can't hit 900 MHz. It might just be the cards wall or it might be due to the fan being locked at 85%.

So I need some help from you (the OCN NVIDIA card overlooking community) on 2 matters. The first part is easy. I just want to know what is the very highest I should go on voltage. I don't mean the highest that you can go with LN2 either lol. I mean the highest "safe" voltage to go with stock cooling. The highest that I can go and most likely won't fry the card.

The second part is a little more difficult (probably not for most of you but it is for me). I am a computer and electronics engineer but my focus is in hardware, not software. So I am not confident with my ability to modify and flash my BIOS on the card to unlock the fan speed to 100%. So what I would like from you is, to take my stock BIOS and modify only the fan speed part of it so that I raise the fan to 100%.

I guess that there is a third part to this too. I also would appreciate it if someone could help me flash the BIOS on my card as I hear its not the most straight forward process.

Any and all help that you guys can offer would be greatly appreciated. I tried asking in the GTX 500 series club but I was told to ask here as I might be able to get more help this way. Hopefully they were right. I'd like to do this ASAP as my card isn't getting hot just now but I'd like to keep it as cool as possible and I already have my other 3 GTX 480's running at 100% fan speed all the time because my 2 computers are 24/7 folding machines. Hell, the noise isn't an issue because I have 2 dealt fans at 100% too so I don't even hear my graphics cards. I have even been thinking about upgrading to the 250 CFM delta fans up from my current 150 CFM fans I have now lol. I'm literally partially deaf and its getting worst every year to the point that I need hearing aides so to make a long story... Well, not quite as long (I know I tend to ramble on and I'm sorry for that guys), the noise doesn't bother me.

I know how, but I do not think you should try any more voltage on air. What are your temps at your highest stable clock?

You can flash the bios, unlock the fan speed to 100%, and unlock the voltage to go even higher than what AB allows in unofficial mode.

Unfortunately, I have only done this 1 time, and I am at work on my laptop. I cannot post a tutorial that is 100% accurate, but let me try to remote and redo my steps. I will edit this post in a sec.

I flashed my bios in dos though. You should be able to flash it in Windows now. I would still flash it in dos though myself because it is safer.

EDIT: My Magic Packet is not waking up the sig rig today.

Try this guide.

It has everything I did and is an awesomly done tutorial.

EDIT2: Are you trying to hit 900 with a memory oc in place? Try it at stock to see if you can get the core/shadder stable. Try to oc memory afterward if you get it to hold. My best guess without knowing temps is that the thermals are holding you back. Maybe 100% fan will get you there, but it will sound like a turbine!

first you need to extract your bios or just download it from here: http://www.techpowerup.com/vgabios/i...ace=&memSize=0

use nibitor v6.00 which came out last month i think, not the older version
open up the bios with nibitor and go to temperatures.... where you see the fan intervals modify it however you wish (can mod the min and max fan speed: ex. max 100% min 30% etc)
http://downloads.guru3d.com/NVIDIA-B...load-2599.html

Save your bios. Use nvflash to flash it to your card(s).
Download nvflash and it's accompanying files and put it into your c directory. Open up command prompt with admin rights.
http://www.techpowerup.com/downloads/2005/mirrors.php this is the correct version that works out of dos... sorry
Enter: cd/ to get to your c directory. [edited command]
Enter: "nvflash"
Keep pressing enter until it goes back to the original C: string
Enter: nvflash --protectoff (just in case there is a copyright restriction)
Enter: nvflash -4 -5 -6 nameofyourbios.rom and hit enter (rename your bios to anything.rom)
press enter a couple of times until it give you confirmation of sucess

If you are force flashing a mismatched bios then you need to enter in a different command... if you need it i'll give it to you, just post back. BTW there are also different comands for multiple cards

I'm away from the house but wanted to respond to both of you. Thanks for the Info and I will come back here when I get home amd address the questions. Thanks again and be back here soon.


Edit: OK so to address some of your questions, I am not trying to bring the voltage above what MSI Afterburner allows. In fact, it's way beneath what they allow. I just want to know what should be the highest safe Voltage to use. Usually the highest that AB allows is the highest safe that Nvidia recommends but it doesn't seem that way to me in this case as Afterburner is letting me take it all the way up to 1.1v and I only have it at 1.025v now. Is the 1.1V the actual safe recommended voltage? I haven't been able to find any info on this anywhere.

I haven't tried to OC anything but the shaders (and the core too since they are locked together). So right now I am at 880 MHz core/ 1760 MHz Shaders/ 1900 MHz Memory @ 1.025v with 85% fan speed. I am overclocking for folding so memory overclocks don't help at all and in fact can sometimes hinder folding as it can increase temps more.

I am going to try both of your suggestions for flashing the BIOS but I think that I will try badatgames18's first as that is the way that I flashed an old GPU before but had forgotten the process. +1 rep to both of you for your help and suggestions and if you can come back and comment on this post then that would be great.
