That won't work! Only Rev 1.2 7970m's are compatible with the HM-Series AND you should follow this thread: http://forum.notebookreview.com/threads/guide-blind-flashing-amd-7970m-modded-vbios-for-clevo-p1xxhm-laptops.688656/ Gesendet von meinem LG-H955 mit Tapatalk

Dunno why Premamod BIOS interferes with your 7970m. Didn't had the Problem at all. If you don't mind having the XMG-Logo you can grab it from here!

You can get a free sample of pressure film from: http://www.sensorprod.com/index.php Choose the ultra low variant. Then you can make sure, if your heat sink is still warped.

Why don't you throw in a GTX 970m/980m?

Basically you have two (three) choices: - Go with the 7970m (Rev 1.2) and follow this guide: [GUIDE] - Blind-Flashing AMD 7970M modded vBIOS for Clevo P1xxHM Laptops | NotebookReview - Go with the 680m/K5000m with proper Nvidia Heatsink and .inf-modded Drivers - Go with another 580m/6990m IMO the first choice would be the best bang for the buck but can be tricky due to the Blind-Flash procedure. The second choice should work right out of the box with inf-modded Drivers (LaptopVideo2Go: Drivers), but is more expensive. And the last one...... hm!

The 680m is good but expensive and you need the Nvidia compatible heat sink for it. You can try the K5000m instead. Why are you stating the 7970m Rev 1.2 wouldn't work on yours?

The 6990m is equal to a GTX 580m. Why don't you go for a 7970m? Would be the best bang for the buck! Edit: Sorry my device is acting weird somehow. Didn't saw the replies. As Khenglisch stated only the Rev 1.2 will work - it's the first production run. 1.1 the second where compatibility was neglected. So if you get your hands on a 7970m Rev 1.2 you get a totally new experience in performance! :thumbsup:

Go for the PremaMod! Should do you no harm!

So does this mean that even soldering it onto the mobo wouldn't work?

Low power mobile SLI variant.... That was personally designed for Mr. Fox to tinker with!

As far as I know the GTX 780m is not compatible with the X7200; may be with a Special mod from Prema but I doubt that. Found anything in the Forums about that. If the 675mx has a vbios for the P150EM/170EM on it, then I could probably use it in the HM machine.

That's good news. I will consider that. Is your 7970m still for sale? If yes, would you please send me a PM for Details? I Need a 7970m Rev. 1.2 for upgrading my P170HM.

@louis1978uk [Forsale] Clevo Hd7970m 2gb (purchased@eurocom 10/22/14. NEW Unfortunately I am not able to PM you. I think I haven't reached my 5 Posts yet! :-) Can you please PM me regarding your 7970m which is still for sale hopefully? Is it Rev 1.2, as I plan to upgrade my P170HM. Thank you in advance!

I have the same issue. Same Notebook (P570WM3 - 120hz LCD), same Graphic Cards, VBios: 80.04.92.00.02, MoBo Rev. 2.1. How did you solve that? Prema meant that actually it is only manageable by doing a MoBo Hardware-Mod, but I am not familiar with this, nor is my Notebook under warranty anymore. Any assistance would be great; I just don't want to use them as paperweight! :-(
