    Have you 150w psu? I too think the cpu could be the culprit. Does anybody else experience shutdown with the i7 720?
    @svl7: What do you think?

    nope, people experience shutdowns with both PSU with the same spec. mine is 720 by the way.

    svl7 is using 920 so he's in the clean

    I did upgrade 6970, the fan at maximum,

    temperature:
    GPU: 60° (idle)
    CPU: 37/38° (core 1,2,3,4)

    Alienware M15x EC:
    Temp 0: 90°
    Temp 1: 44
    Temp 2: 44
    Temp 3: 41

    Repaste the GPU and check whether the heatsink is making proper contact with the die, also check out the backplate / heatpipe mod.



    Hmm, I dunno... there's only one thing that I can think of which could have an influence (when looking at the CPU), but that's all speculating.
    The 720qm comes with 6M cache, the 620m with only 4M, that's not much compared to the 8M of the 920xm. The less cache, the more the CPU needs to access the RAM, which increases workload of the bus. At the same time, the faster GPU uses the bus a lot more than any card which was regularly available with the M15x, this might lead that a component which is responsible for the bus overheats or whatever.
    As I said, that's only wild guessing, I don't know the detailed specs of the M15x, but the bus certainly was never designed for such a traffic. Finding out whether the CPU is responsible for the crashes is only possible by checking what happens when there's an XM in the system.

    nice explanation svl7, may be that's the final answer to the solution. can other forumers confirm on this ? meaning those with 920/940 and 6970/6990 combo have shutdown issues. examples of this is at around less than 15 minutes, shutdown occurs when playing games, temperature never reaches above 90.

    Thank you svl7! That makes sense! Someone on a french forum asked dell about the 6970 and M15X, the technician answered that the card's frequency bus was too high for the motherboard.

    Svl7 ,

    I need some guidence in here or anyone could help me to check if this is going to be ok or no:

    I want to upgrade my M15x , it is the first release that came with BIOS A01 and I happend to be one of the people in disaster of the Failed A03 BIOS , sent it to "Dell U.K" since I live in Saudi Arabia and they replaced the Motherboard and that was like almost a year and a half now.

    Now I have BIOS A09
    Processor :i7-Q720.
    8 GB RAM @BUS 1333.
    GTX 260m.
    Fatcory shipped PSU (150 Watt)
    6 Cells Battery.

    I want to upgrade to either AMD 6970m or 6990m , But I went through all of this thread and I've seen many people having problem with Shutdowns and most of the people having this issue are "720Q" users, no one "that i've seen yet " with 920xm or 940xm having this issue.

    I really want to go for the best out there which is "I can say 6990m".

    What should I really have to put into my consideration, Will I get shutdowns with my current 720Q Processor or I have to upgrade to 920/940 xm?Will I get more heat that I need to do something more than applying thermal paste? What about HDMI+Audio over DP ?Do I need to flash vBios for the 6990m or 6970m to work with My M15x.

    Is there any big difference between the 6970m and 6990m in terms of modern graphic processing and games ?

    Is this 920xm Processor ok ?Shipping by EMS Intel Mobile CPU Core i7-920XM Extreme 8M Turbo 3.2GHz In Tray | eBay

    Is this 6990m ok ? ATI Mobility Radeon? HD 6990m GPU MXM 3.0 Type B | eBay

    Is this ok 6970m ok ? ATI Mobility Radeon™ HD 6970m GPU MXM 3.0 Type B

    If you guys having any of the above components for selling, please pm me.

    I've read the 154 pages (ouch!) and listed people having shutdowns (like described by Hel20es post 1533). Here's a summary:
    -darth voldemort cpu i7 720
    -kaizenmx cpu i7 740
    -MrValle cpus i5 430 and i7 840
    -Hel20es cpu i7 720
    -Kumquatwrath cpu i7 620
    -Ninefingers cpu i7 820
    -Myself cpu i7 720

    nice find and thanks for your hard work flo, yup that should prove my point. there are no 920/940 in the shutdown list.
