    Found a nice spike in performance from 1.07 they uploaded in December. They just put out 1.08 January 3 and I have to say, do not get this one; not only are temperatures and fans unchanged, the increased performance is now gone. Previously in the same scenarios on userbenchmark, was getting much higher 89.4 on graphics with the same Curve on MSI Afterburner (the usual that I play games with is overclocking a curve and flatlining at 1775 MHz). 1.06 I had 85.9 on graphics and now with 1.08 I am back to 86.7. These are multiple tests being run with slight variations but overall the same results.
    Key take away, I wish I could downgrade my bios to 1.07 but I don't really know how and I don't want to screw this up. Very disappointed that not only is max fans STILL not there, they crippled a perfectly viable BIOS that saw smoother gameplay in CoD Modern Warfare when I had 1.07. Why they did this? Don't know. Lenovo software engineers seem to be terrible at what they do.
    For reference, I have the i7-9750H + 2070MQ.

    Hey guys. Owner of an Y540 here with RTX 2060 85W. Does anybody here have vBios of Y740 with RTX 2060? I was curious as if the bios is 85W or 90W version. If it is the 90W then I will try to flash with it. Thanks
    The reason is I tried other vBios from other brand. Works fine but I cannot use it with dedicated graphic mode. The screen would be pitch black. Maybe vBios of Y740 can works fully.

    Curious if anyone with the RTX 2060 is scoring higher than this and if so, what their settings are. I realize I'm being bottlenecked by my 8GB RAM (Hard faults everytime in games) but I'm looking to upgrade to 16 soon

    Do you have a copy of the 1.07 BIOS file?

    Can you link me / host it somewhere? I would love to switch to it and test it out.

    Thank you!

    Here are mine if you are curious. The first one is through Afterburner OC Scan so the core clocks are all over the place. The second one is after I undervolt it since I noticed there is a power limit when running at 99% gpu in games anyway and ithe core clock is +260MHz. Both have +1100MHz memory clock.

    Undervolt: https://www.3dmark.com/3dm/42804584?

    Edit: Almost forgot, yeah runnig 16GB of RAM in dual channel

    P/S: Still curious about Y740 RTX 2060 vBios. Can anyone link me please?

    Thank you!

    What about going into bios and enabling the "roll back" option? And then flashing it?
