    Nice! Did you use NvFlash or a programmer?

    I used nvflash. Mazed's VBIOS was signed, so it was very straightforward.

    Can anybody with experience tell me the difference between the 7730 and 7530 except for the size and higher quadro options? And is the bigger case beneficial at all for airflow and heat dissapation?
    Also how does it compare to the 5530 which looks also very attractive for someone looking for a new laptop.
    Apparently the 7730 is louder than the 5530 on max load. But the average noise is lower on the 7730 compared to the 5530. Can someone tell me how noisy the individual Dell laptops are (I got my information mostly from the tests on notebookreview.com). Maybe someone with Dell expertise can help me in my thread here:

    Thanks in advance for any infos.

    Well read so many pages except for the intro :rolleyes:. Thanks
    Since a few people purchased those systems now is there a comprehensive list of all the negatives of those laptops?

    I'm curious if you are seeing any throttling that you weren't before? Is the 7530 power throttling with this GPU? (GPU-Z "Sensors" tab "PerfCap reason" will reveal this if you leave it open during a benchmark or something.)

    I was definitely seeing Pwr throttling with the stock vBIOS; it hovered exactly where the power limit was defined: 65 W.

    The new vBIOS lets the GPU reach 75+ W of power draw, but like I said, I haven't done any detailed monitoring and benchmarking, yet.

    What that would tell us is if the decision to power limit the P3200 was a technical or a marketing decision.

    Indeed, I was also wondering if maybe attaching a 240W adapter would let the P3200 with 7730 vBIOS perform a little bit better (assuming that there really is a sort-of good reason that Dell decided to limit the power in the 7530).

    It would be an awfully odd "marketing decision" considering that Dell hasn't even disclosed that there is a difference between the P3200 in the two different systems...

    Calling it a 'difference' is putting it mildly; there's a 35% (or 26%, depending on which is your baseline) difference in the power limits.

    I never got the reason for that, from the outset. The GPU runs at a balmy 60 °C under transcoding load (ffmpeg nvenc_h264), and perhaps 3-5° warmer under an intense gaming load (AC Odyssey, Kingdom Come: Deliverance).

    There is plenty of thermal headroom for more power, and perhaps a little more voltage.

    Since I have Shadow of the Tomb Raider, AC Odyssey, 3DMark, Cinebench, and ffmpeg, I'll run all these over the weekend and prepare a detailed report. I'll see if I've got any other games that have built-in benchmarks (since there's little statistical point in running through games/benches without repeatable results).

    If any of you have suggestions for benches (ideally graphics-focused), please let me know.
