    And actually, if you connected the Rift S via thunderbolt by itself it would probably work. In the nvidia control panel you'll see that the video card actually handles the thunderbolt connection. I had a bunch of other crap connected to the dock, including another display so I'm betting the problem was not enough bandwidth. If it doesn't then no big deal, it's only a $7 cable or whatever for DP to thunderbolt. The oculus software was picking it up as a DP connection.

    I’ll definitely have to try that out then. Gotta put my trusty Oculus rift up for grabs so I can upgrade. And I just pulled the trigger on an Omen 17 RTX 2080 / i9 9880h. There was a 10% off coupon that made it too good of a deal to pass up. And ironically cost $100 less than the Omen 15 with the same cpu and 2080 max-q. :eek:

    Hello, new to the forum. I just got an HP Omen 15-DC1054NR for testing, just wondering if anyone knows (if it's possible) how to access advanced firmware (BIOS) on these machines? For a gaming computer the BIOS on this model are very basic (no pun intended) :)
    If stock HP firmware doesn't allow for advanced functions,are there modded firmwares we can install on these models that would? I just updated the machine to the latest F16 firmware from HP's site. Only have a few days before the return window closes, so trying to do my research fast to help my decision.

    I believe this is the older 2018 model, i7-9750H, 16GB RAM, 1660TI/6GB.

    If anyone can offer any pointers or share some info I'd appreciate it!

    TIA

    Hi all,

    Thank you for the lots of input provided in this thread about the Omen.

    I got the I7 9750H RTX2080 17inch version, after repaste of the CPU with LM and the GPU with MX-4 it works great in thermals. Also the CPU is way less jumping in temps and not throttling in short peaks while fans haven’t ramp up yet. I upgraded to 32GB of RAM, first I got HyperX Impact 2666 CL15 sticks, but in Dual Channel they always crashed (was mentioned here earlier). Now with some random Crucial 2666 CL19 from amazon it’s working fine. Where I didn’t find information about, if there is a 2,5” connector included, when you buy the SSD-only version. It’s included in my SSD-only machine, including some dummy in the 2,5” bay.

    One thing I have issues with and need your knowledge guys: Power Limits

    I am using Throttlestop to apply -110mV undervolting (BIOS F.16). Intel XTU is not installed, XTUservice task is running in task manager.
    But I cannot adjust the PL1 power to a higher level when I use the standard profile in OMEN Command Center. It’s capped at 45W PL1 long term power on CPU only. When I load CPU with prime and GPU with FurMark it drops to 35W. I can adjust lower values though.
    In the FIVR window, the driver for “disable and lock turbo lower limits” is installed and it’s ticked.
    When I choose the performance profile in OMEN Command, I can adjust higher power limits. But the fan curve is really aggressive and I would prefer the standard one and run at 80°C instead of 70°C.
    Is there any way to get higher PL1 with standard profile? How do your configs with Throttlestop look like (or are you using Intel XTU?)?

    You don't need to use the "disable" pack, that's for machines like Dell that have ridiculously low limits. HP has let this gloriously run free. The service is there because OCC uses it but there's no harm in disabling it (I have to no effect).

    I gave up on XTU and switched to Throttlestop. Yes, XTU is pretty but damn is it weird, different versions don't run, conflict with Omen Command Center, won't install, it has a lot of overhead, and I really didn't like that the service is always running doing god-knows-what.
    Throttlestop fixed all my Omen problems, along with just a MX4 repaste. I can now run the i9 at a constant 90W, with the temperature stable in the 80s. It is still very spiky but that's just the nature of the beast.
    The three modes in Command Center don't change the fan ramp at all as far as I can tell. They just change the PL1 and PL2 limits, and Performance mode also seems to up the GPU performance in my case (it reaches higher frequencies playing the same game. It's probably also a power limit and not actual overclock). I just leave it in Performance mode all the time now, after the repaste it stays quiet while not gaming, and if I want it to stay silent during a videoconference or whatever I'll just put it in my Throttlestop gaming profile to limit CPU usage.
    I've written a lot on Reddit about why PL1 and PL2 limits aren't great for limiting CPU temperatures during gaming. If you want the links lemme know. The best way to control this machine is with two profiles in Throttlestop (you can make your quiet mode as well): One for max CPU for general use, and one for gaming that prevents CPU thermal throttle while gaming. This machine has shared heat pipes. When the GPU is idle the CPU can run at max. When the GPU is running at max, the CPU cannot without overheating. The power limits don't fix this because the thermal scenario is just too complicated with all those cores, and no way of knowing which game is however multithreaded. It handles 8 core loads of the same wattage much better than single, even a single core can turbo up to 4700 MHz with a 35W cap and will still hit the temp limit. So I don't even bother, just leave PL1 and PL2 at 90 W, and set the Turbo Ratio Limits at 38X for a gaming profile and the temperatures stay under 90 C.
    There are high and low limits burned in to the -H chips. You can't set PL1 below 35W. As described above it's still capable of overheating while gaming at that setting (sometimes). You can't exceed the full Turbo Ratio Limits of 41X for 8 cores (or the intermediate limits for 1-8 cores active). You can set it, but it won't take. How do I know this? With all set to 48X, and a -.100V undervolt it will bench all 8 cores at 4100 MHz at about 90W. With a -.125V undervolt it will bench all 8 cores at 4100 MHz and actually draw well below the 90W PL1 setting. This is interesting, because it means except for helping temperatures, undervolting below -.1 V doesn't increase theoretical performance in any way. Now I know what the -HK chip is really for (IF it can be cooled and powered, can run like the desktop chip).


    Some extra info: This machine doesn't run out of PCI lanes, I have 2 SSDs and 1 HD in it and they all work (and bench) fine. I don't own anything thunderbolt, so that would be my last concern; that if it is out of lanes, the TB3 port may not work or it may cut something else. I haven't seen anyone else post about this issue if you can really load it out fully without issues.
    I play a mix of new and old games. The demanding ones DO benefit from MAX fan setting--your repaste and undervolt will throw off the fan ramp. The only thing I use Command Center for these days.
    It doesn't breathe well, I removed the black plastic shield from the back panel that covers most of the inlet screen. This, with a cooling pad, helped my SSD temps a lot.
    I put some black tag board under the rear feet to keep the ejected air from blowing back underneath and moving rearwards (also to protect my aluminum USB hub behind the machine that was scorching from the blast). At a glance it looks like it shoots rearwards but looking at the inside of the bottom cover there's outlets on the bottom, as well.
    I'm using the F.22 BIOS, it doesn't have a Plundervolt fix and undervolting still works. F.24 is out but it just says something about "additional display panels." Like I trust them.
    I'm very interested in trying the 190W vBIOS mod but don't want to lose my miniDP port. I'll save that project for the next quarantine when it's out of warranty. Or when I finally buy a game that won't run at 4K, haven't found one yet!
    Oh, since you were interested in noise and fan ramp--SpeedShift with EPP 64 works great on mine, it can reach max but it idles down around 800 keeping it mostly silent for Windows work (until something excites it).

    Hi Guys
    I'm just wondering : is any one here have the OMEN 17 with 4K screen to share the info ? plz ! seems like it running 3D benchmark nearly 30 FPS less than my X7 V7 ,evenly O.C core ,memory clock and screen resolution (in 1080p NOT 4K) but almost 28 FPS less is strange ! may be the 8750H ,as i heard some one mentioned the 8750H running game worse than 7700HQ ! any input will be appreciate.

    Hi All!,
    this is my little contribution to the community. I have a OMEN 17t, i7-9750H RTX 2080.
    I was thinking to install a 5TB hard disk to my laptop.
    "Technically" only is possible ot install up to 2TB of mechanical 2.5" HDD or 4TB-8TB os ssd. That means 7 to 9mm witdth as maximum. A mechanical 4TB or 5TB mechanical 2.5" is 15mm width so it is impossible...or not...XD. I finally achieve to install a 110 € external 5TB USB 2.5" into my HP :)
    You can see my photos...

    Will i be able to get 45watts on the cpu in gaming or will it be reduced to 35?

    I think that was your question? The Intel 45W rating comes from all 8 cores running at the base clock, which I think is 2.3. Games don't load all 8 cores at 100%, the actual load is dynamic between your CPU and GPU, so there's really no way to manage it other than with monitoring while gaming. I use a second monitor with Afterburner for this, but the 3.8 has worked magic for me. Watts don't also translate directly to a reported CPU temp, it depends how it's distributed. Some games run hotter than others on the CPU. I also haven't found a utility that reports GPU wattage; Afterburner will show the load and frequency from which you can infer but running at 4K Ultra the 2080 doesn't always max out on mine (probably because it's gsyncd to 60 Hz). Every system is unique.
    Mine runs games with the 3.8 limits. The power graph can show some spikes above 45W during loading times, but during play I've never seen a game that CPU intensive. They all seem to hover around 30 to 35.

    hwinfo has an OSD function that can output the GPU power. Enable it in the setting then it will send the reading to RTSS
