Nvidia GTX 900 cards custom bios (upon request ) - Page 76

So has anyone undervolted their cards to get the most performance out of the cards while keeping temps low?

That's always kind of the goal if you have a specific target clock in mind, run it at the lowest possible voltage that you can. But if you want to run the highest possible clock, you keep pushing, and that usually means adding more voltage.

Well said! That's basically everyone's dream: high performance, low volt, low heat, and quiet. Like you said though, higher clocks usually require more voltage.

It sounds like the best thing for you, vmirjamali, might be to just leave the voltage stock and see how far you can push the frequency on the stock volts.

yea I'll have to give that a try. Do you guys use afterburner to do the initial testing or straight to bios tweaking each time?

I use a custom bios and precision x. I have a base overclock set up in the bios that I use daily, and if I need more power, I bump it up with pcx.

Core clock 1519mhz & 3.8ghz memory clock & 1.28v (up to 1.3v ) & 370W TDP & boost off

you can start pushing the clock farther to find the max stable clock for that card.. you can use 1.3v on that card since the VRM have active cooling ..

keep in mind the software will report 1.26-1.27v max while the card pull more than this..

My GPU is still downclocking to 540MHz core after gaming for a while. The only thing increased is mem (from 7600 to 8000), but I don't see how could it make the core to downclock. Higher core (1530 or so) either makes it downclock or driver crash. I guess I just have a really ****ty card as far as core overclocking goes. May I request the BIOS adjusted to have 1480 base core and 1.20v (up to 1.3v)? I figured that since I play CPU-bound games more often than not, having the card work at its limits is not necessary for me at all times, so I don't have to have it running at higher voltage. Thank you. I can also take suggestions, if anyone has any.

Can someone take my oc'd bios from mr. dark and get rid of the fan boost on it? Want to see what temps are like without the 400+ rpm fan boost.

My original bios fan settings were great. bios_970msi_mavi.zip 273k .zip file

540mhz ? Never seen a card throttle to 540mhz even if the TDP usage over 120% !

check the voltage/TDP usage under load and report back! .. I can made a new bios for you but we need to know the reason for your problem now .

Here you go!

2 bios there..

1.23v bios have the stock fan curve and the other one have lazy fan curve thumb.gif

Is it dipping to 540mhz because it's not under load, or is it actually throttling. There's a huge difference between a place in the game that's not stressing it at all, and in a spot in the game where it's being stressed, and STILL dropping core clock.

If you want to lock in the boost clock, use KBoost in Precision X.....if it still does it then, then you'll know your card has issues.

help!!!!


im on a friends pc right now... i flashed bios, hit yes and yes to confirm, then rebooted without going to display adapter to re-enable the driver first by accident, and now all i get is my monitor cycling through colors it wont even load up my mobo bios...


am i screwed?
