g770 xp amd driver

[noone42]

Hello 2 all

I am VERY satisfied with my new lenovo g770 except one thing!

All drivers i needed for Windows XP Pro SP3 are there and working fine.

But i can't get my AMD HD6650M getting to work in XP! (HD6650M is running great in Win 7)

Problem might be the switching between the onboard (or better incpu ) Intel HD3000 graphics ( HD3000 works fine in XP )

and the extern AMD HD6650M. Did someone else has this problem and find a solution?

( I tried patching other drivers to proper ven 1002 dev 6741 subsys 397617aa but no success )

Any help is really appreciated!

Thank you very much

Hi and welcome to the forum!

To the best of my knowledge, Win XP doesn't support graphics card switching. I suggest to consider upgrading to Win 7.

Hi there and thanks for your reply.

As i wrote this card runs fine in Win 7

I multiboot 6 OS + memtest on my G770 and i need this card to work also under XP. ( If possible)

But thanks for the hint that XP maybe dosent support any GFX switching. I try to check this out.

Any other good advice is still very welcome.

Thanks!

XP definitely doesn't support switchable graphics.

You'll have to set the BIOS to either discrete or integrated.

Hello again

On my G770 Bios i only can select between UMA ( integrated Intel GFX ) and switchable.

So i cant force discrete to use by default i guess(??) Maybe i need a bios update ( or unlock  ??)

Looks like XP really cant switch GFX for performance / accu lifetime

Same problem with NVIDIA GFX cards useing OPTIMUS tech in XP / VISTA

Thanks for all your help!

G770 is still a great buy!
