    Hi, am new to the forum, did anyone find the model numbers for the IGZO 4k panel for the 7730 ?

    (I have search and scanned through 80% of the pages and so far cant find it)

    Thanks in advance

    Hey guys, do any of you guys know of a mobile workstation that has a Quadro p5200 mobile (not MAX-Q), so that we can get the BIOS of that graphics card and update the firmware on the 7730 p5200 to get more performance?

    Interesting idea but I think that's less likely to work than the P3200 vBIOS flash success that @Ionising_Radiation had. I was looking at the Eurocom Tornado F7 workstation specs this afternoon. It has a Quadro P5200 rated for full performance at 160W. That system ships with a 330W power supply. Laptops that I've seen with GeForce 1080 (not max-Q), which has similar specs to the Quadro P5200, all ship with power supplies in the 300W+ range. For reference, laptop 1080's pull 150W+ and the desktop cards pull 180W+. There hasn't been any architectural advancement in the GPU here to reduce the power requirement, these chips are all running Pascal 16nm, the same GP104 chip. I'm thinking that the P5200 just needs more power to run at full speed than the Precision's 240W power supply can provide (plus powering the rest of the system and the CPU at turbo speeds) and that's the main reason that the GPU is power-limited in this system. Possibly Dell played it a little more safe than they absolutely needed to (like with the 7530/P3200) and it could be possible to eek out 10% more performance, but there is definitely a numbers problem when it comes to power.

    Even if you can attach 330w PSU, won't the VRM on the DGFF just overheat?


    If it doesn't overheat and throttle down there's potential for permanent hardware damage.



    Seeing as the DGFF's mylar sheet covers everything except the core, VRAM, and some inductors led me to believe that the VRM isn't or just barely cooled.

    You have to also remember that Quadro cards even with their Max-P (normal TDP) variants are made with less TDP compared to their GTX counterparts even though the core is the same.

    The MSi on the other hand, they use GT73/5's MXM PCB which can actually handle 150+ (their 1080 is rated at 180 or 190w, with an external power cable). That's way more robust than DGFF.


    Plus, since DGFF outputs directly from the card itself and not through the motherboard, there might be some bios inconsistency.





    Rule of thumb when crossflashing is to make sure the cards are as close to one another as possible, which isn't the case here.

    According to NotebookCheck, the 4K panel is a Sharp LQ156D1.

    Furthermore, @Aaron44126 did mention the panel number here :)

    That is 7530 and he is asking about 7730...

    Someone could attach the Alienware 330W and see what happens. I suspect that the system wouldn't even try to utilize it.

    :facepalm:

    You're absolutely right. I guess we'd just have to ask Dell about the part number, then.

    Well at least you Dell Pres folks get a 240W power supply. We ZBook G5 folks have to slum with a 200W supply. :)

    EC limitation most probably.

    No more getting "free" performance, just be a good goy and buy the next gen laptops for a few % extra performance from (((us))) :^)

    Well, the Precisions have DGFF...

    Edit:

    @THX_Jedi, looking through Panelook, there are only two panels that satisfy the IGZO UHD requirement, from this search. Only Sharp panels are IGZO, so it's either the LQ173D1JW31 or the LQ173D1JW33.
