MSI GX740 with 5870 1gb ddr5

Only possible with vBIOS-Flash. AMD GPU Tool makes no changes at the voltage. Till now, it's seems there is no soft-mod for volt-changing.

First, automtic Powerplay as on desktop cards isn't implemented alright. Really stupid
I still have to switch via CCC-profiles or Win7-energy settings.
The vBIOS of MSI GX740 or X7811 have only 2 Clocksettings. "Power" and "Energy Saving". Asus G73 has 4 clocksettings and the card e.g. switch to an extra UVD (Avivo) setting while playing videos or youtube automatically. This would also be fine for us, because at 200/250 hires videos (1080) are stocking. OK, not really a problem
I've been using RBE 1.25 to change the vBIOS and Winflash for flashing. You could also flash with Atiflash via USB-Bootstick or so. There is also a tutorial at techpowerup.

But the Clevo is maybe a little bit different. So be patient!
The original vBIOS of GX740 (same as X7811) you can find here.
You have to set the voltage manually.

thanks @tilla.

I am totally comfotable flashing VBIOS, I will use ati flash. People have been using the Clevo and MSI Vbios on the G73 with success so I dont think I will have any problems the other way.
I am currently using amdgpu tool but the fact it doesnt lower voltage is really frustrating. I get about 30mins on battery with the clevo which is rediculous!

I may just look at undervolting like you have to .95v at stock settings. Did you notice if this has improved your battery life at all? Only thing is my card happily clocks to 900/1100 so by lowe the standard voltage will eliminate my overclock.

Thanks for the link to the VBIOS. I will download it and take a look at yours compared to my clevo

So guys, is it i5 or i7 CPU? Because i see videos and reviews with i7, but where i wanted to order, and even on their site ( MSI Europe ? Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more ) it says i5

[GroundhogDK]

The Gx740 sold in Northern Europe is i5.

[Zeux]

Indeed, I'm swede and mine came with an i5 but it's more than enough anyways.

[tenorx]

Aha, so i have to take the i5 one. How much will it affect the performance?

Editing my old post. GX640 Bios will not work on 740. See below.

[Ghola]

Did you use the CD method or USB to flash?

[kosti]

CD. Took like 5 minutes including time to burn the CD.

!!!!!ALERT!!!!

I Just got word from Warner that the GX640 VBIOS will not work on the GX740!!! Don't do it! I was confused because the original MSI thread said that it's for both models. Here are his words:

GX640 VBIOS cannot be used on GX740 because it will kill GX740.

Sincerely,
Warner

Hope nobody bricked their 740!
