    Proof here:

    [​IMG]

    I am using the Catalyst 11.8 Preview Drivers so the M8900 is listed as a 6970M (Hence it says "AMD Mobility Radeon 6900M Series").

    Also, this is with stock clocks with no warranty-breaking hardware modifications of any kind.

    You could PM Mano I'd guess. If Mano requires proof that M6600 is working properly on Dell OEM Drivers, I can verify exactly so via GPU-Z for you all. However, I think the M6600 is working properly as it should and your M4600's are having some driver or vBIOS problem that needs to be rectified.

    PS: If you are reading this as of today 07/30/2011, you will notice I don't have a single Dell Precision in my signature. I am doing a profile switching thing with a fellow NBR member who is currently lurking around with my signature. I really own a M6600 so bear with me here haha!

    Thanks mate. Can i guess your m6600 is running A03 bios and other m4600 without this problem is also running A03 bios?

    Those affected m4600 is running A04 bios. My is and here at Dell the fix in A04 bios state

    Fixes and Enhancements
    1. Reduces LCD panel flicker at low brightness settings.

    Based on my desktop experience of some AMD GPU, the GDDR5 vram when changing speed will cause display flicker. My guess is Dell just stop the GDDR5 vram from donwclocking to fix the panel flicker. All A04 m4600 GDDR5 is stuck at 900mhz... A lazy way i hope is not inert hardware fault and can be restored or else my m4600 will be send back.

    This is a major flaw! A killer to battery life and heat....

    Well I do not know if the M4600 and the M6600 uses the exact same BIOS files but yes my M6600 came shipped from the factory with A.03 Revision.

    PS: However my first M6600 had that problem you just highlighted but this new one doesn't so but the one I have now doesn't fail to downclock or anything! This is strange...

    sigh flash back to a03 bios, dont working here.
    my last try is a fresh install of win7 and see how it goes on.
    could be sound like a hardware problem in batches as u highlighted..

    I was going to try going back to A03, since I'm at A04.. But it sounds like that doesn't fix it.
