    Works fine on 2D mode with video, but even a second on 3D clocks i'm getting stripes. Is there any solution to this? Have tried to use RBE to set all clocks to 550mhz core and 500mhz mem, no luck. Have replaced thermal grease no change. would really appreciate any suggestions. Have reinstalled windows 7 64bit, no luck. Can't RMA bought the card as a replacement for the dead 8600m gt on ACER Aspire 5920.

    Sorry to hear that. Sounds like a dead GPU :(

    Slightly off-topic: I have a 4650 in my own 5920G and that has been running fine but temps have been increasing overall and the whole laptop is in dire need of a complete Thermal Grease overhaul. I installed the 4650 with the thermal pad supplied by mxm-upgrade.net, but since I have no more pads anymore, I was wondering whether there's any downside to using thermal paste instead. Care to give me your usual range of temps before the chip started dying?

    EDIT: About the downside, I'm referring to the loss of thermal conductivity due to having a thick layer of thermal paste because the die is thinner than the old 8600M GT...

    When the card was working, no load: ~50degreesC, with load: ~87degreesC, was working well for more than 6 months with copper mod thermal grease for GPU and thermal pads for memory. After the GSODs started I replaced pads with thermal grease; without load temps maybe slightly lower still ~50.

    I suspect one of my card's DDR3 modules has failed, shudnt it GSOD on 2D as well?

    A copper mod you say... Hmmm...

    EDIT: not necessarily. I have a dead 7600GS. It displays 2D with some mild corruption despite being completely unable to do any 3D. Just depends where on the card it fried.

    Grab this. It's a GPU-Z vBIOS dump: https://www.dropbox.com/s/kgwyu26gsye0vjj/Mobility_HD4650_RV730.bin

    You can mod that as well if you want to. I modded it to undervolt to 0.9V (instead of 1.1V) and max fan speed but never flashed :(.

    I too have had cards that would do 2D fine but the minute you fired up anything 3D, the video card would puke pixels all over the screen or GSOD on me.

    Sucks that it's a Mobility Radeon though. That makes it hard to swap out. :(

    Not here. All three of us here have the same card in our Acer 5920/5920G laptops from a manual upgrade. Yay removable MXM modules.
