2019 15" Lenovo Legion Y740 (RTX2060) [9th,6C,H] + RTX 3070 @ 32Gbps-TB3 (Mantiz Saturn Pro) + Win10 20H2
When you go into hwinfo what does your PCI link width show? Compare with this photo. If it 2x then you may have gotten unlucky with Lenovo.
Looking at your benchmark screen it does look like the dGPU is still installed. I wonder if that could be causing the problem. I just ran Heaven and got 4171.
@styl_magnus, I'm not en expert, but you might look at the node: where the nvidia card is connected (and start hwinfo when it is under load):
I also have a node where 2,5 is reported, I have no idea why are those many nodes and which are relevant:
(I'm not quite sure what is my speed)
@styl_magnus, your link speed ought to be higher. I'm not sure if this is the OPI issue described in the buyer's guide. When you disable the dGPU how are you doing that? In windows or are you disabling it from BIOS?
@zoltan_uszta, those were my settings as well. Extreme @ default 1600x900 windowed.
What is your device to host bandwidth? I think you can get it from CUDA-Z. I think you are looking good from what device manager shows.
Is your CPU throttling during the benchmark? Your PCH (laptop's TB3 controller) might be getting too hot.
@phila-delphia, tested with other games as well, and experience was better vs when playing AC Odyssey:
- CoD Modern Warfare (Multiplayer) - 60-70 fps, mostly high, RTX ON
- Mortal Shell - 60-70 fps, Ultra settings
- Witcher 3 - 50-60 fps Ultra Graphics (Hairworks Off) High Post Processing, 60-70 fps (can go up to 90fps depending on location) Very High Graphics (Hairworks Off) High Post Processing
Will continue testing with my other games and post results here
Thanks for your build!
Could you do a comparison between the 2060 dgpu and the 3070 dgpu?
I've been contemplating whether I should get the 3070 or not, I have a rtx2060 omen 15 which almost has the exact specs with your y740 so it would really help if I could get further results before finally coming up with a decision.
when I start Heaven, the device to host bandwidth showed falls back to 1000 MiB/S (and heaven will also show lower results, around 2300, I guess they share the bandwidth)
I don't see any CPU limit in throttlestop, I think I'm fine there
With 80 Mhz overclocking (GPU Clock showed 2175 Mhz) I get 3500 points, it is still not 4000 (do you have a higher GPU Clock maybe?):
