GX740 vbios help

Hey guys,

I've been having some serious heating problems with my 5870m when it comes to playing Dota 2. It runs at 90+C which it has never done before, and it was all after I updated my vBios to 31.

Ive been trying to find the old 23 bios but no luck on finding links.

I was looking at this thread but megaupload is well you know.....

If anyone has there vbios and wouldn't mind sending it to me or uploading it somewhere I would greatly appreciate it.

I also noticed at full load it runs at 1.15V even though when I run RBE on the flash I used it shows 1.05V @ 700/1000. I've flashed it 3 times already and it still stays at 1.15V also when I download the vBios with GPU-Z and open that with RBE it shows 1.05V


Kinda odd.....

Just a quick question, if you got this from your video card could you tell me what ATI drivers you use? I'm trying to fix my heating issue and it seems that a certain combination of drivers / bios fixed that. Right now I'm looking at someone who said 027 vbios and 10.11 ati drivers.

Anyways thanks for the post ill use that for now see what happens. I remember when I first had this laptop it had idle temps at 35-40.

 

I don't have that card, I just happened to have a copy of this VBIOS.
If you have heat issues you should clean the fins of your heatsink and maybe repaste your system. A VBIOS change won't help, unless it changes the core voltage.

 

Yeah I'm going to be doing a repaste later this week and clean out the copper cooler. The vbios was because for some reason my 031 wont let change voltage from 1.15 to 1.05 no matter how many times I edit it with RBE and flash.

Anyways thanks to your link and that website from your 6970m post ill also be buying some laptoplifts.

 

Try to reset your CCC Overdrive profile to default. There is a button at the Overdrive tab in CCC. The clockspeeds and their voltage is saved in this XML file and sometimes the vBIOS values are just overriden by them.
Try it.
My 1727 barebone (X7811) with all it's mods idles at 100/[email protected] at 40°C. On Furmark IMO it reached 80°C (700/[email protected]).

You are right, the latest vBIOS seems to be less stable (vRAM timings?).
IMHO I'm using a modded 23's too. I'd uploaded my ModPack.
But there isn't a "cooler" vBIOS out there. It's just a thing of core/voltage, as svl7 said.

 

Yeah, I already did a re paste and cleaned out my stuff and now it idles about 40 with 100/100 @ 0.9 but ill try to lower the voltage if it is stable for my application usage.

Tyvm for your modpack.
