7970M on MSI GT683DXR (16f2)

Recommended Posts

Hi all.

I am commited to replace my 570m by a 7970m in a 683dxr,

I have seen a Dell card with vBIOS 015.021 (uefi)

As I have read I think it should work as long as my computer bios has uefi enabled also.

In my current BIOS i have the option:

Legacy USB Support: [Enabled]

Is this the right option? Or shall I flash my computer with an unlocked bios and enable uefi with another option?

Thanks.

You will need the unlocked BIOS. It adds the ability to boot from UEFI. you will also need a 5970m heatsink/and or dremel.

Fantastic!

So it should be as easy as:

1) Install the unlocked bios (16f2 or 693?)

2) change to boot from uefi

3) Buy the Dell 7970m 015.021 and the 7970m msi heatsink

Thanks again

Yep sound right.

Use 683 BIOS for your notebook.

If you buy the 7970m heatsink unmodified (so 5870m heatsink from previous MSI), you will need to use a dremel to cut off a couple corners of the heatsink.

Is not any 7970m msi heatsink out there that I can use without dremel?

Otherwise I might go for the 770m cause all would be easier and there would not be a huge performance impact I think.

Once installed the unlocked bios and changed to boot from uefi, would I be able to start the OS (Win7) without further modifications?

Actually, you can use the GX60 or GX70 heatsink. I forgot those came with the 7970m/8970m.

Yes.

Just ordered a Dell 7970m (vbios unknown) + msi heatsink.

I am booting from unlocked BIOS in legacy mode.

May I need to flash the vbios to disable enduro? Or just the 16f2 will ignore it since it doesn't support it?

The Dell should work out of the box. If it doesn't (clocks don't go to 3D) then you can flash the Clevo without Enduro.

Finally I received and installed the 7970M this week and is working perfectly fine in a GT683DXR (16F2). Just for recap:

- Dell cards with vBios 015.022 are plug and play when booting from legacy mode using the msi unlocked bios

- CPU throttle problems (Far Cry 3 for example) are solved using Throttlestop 4.0 and turning it on

- It may be obvious but a proper 7970M heatsink is needed (or a modded one)

- No x-bracket needed

- Scored P6337 in 3dmark11 using default clocks (AMD Radeon HD 7970M video card benchmark result - Intel Core i7-2670QM Processor,Micro-Star International Co., Ltd. MS-16F2) with latest beta drivers

Thanks all
