    I remember hearing something about that before.... Whats the reason for throttling?? I thought the LC had power draw rated of 345w vs 295w on air cooled models. Suprised the drivers can tell difference in GPUs after BIOS flash.

    There must be a flag somewere.

    I tried loads of drivers and the inicial drivers were ok with that. Later something changed on the drivers and the moment it tries to boost it starts to trottle.

    Vega is a great card, well tunned it will hit 1080ti performance . Be aware that some games dont like HBCC on.

    Yea, did some googling and came away with drivers 19.4.1 is where the issues starts. Couldnt find anyone testing if lastest drivers still caused issue since now we are at 20.5.1.

    Feel like people are slowly going to other cards and now that we have new cards due out later this year people are not pushing Vega cards as much

    Your right still a great card, it keeps up with (5700,5700XT)(2060S,2070) most other mid range cards and its going on 3 yrs in August. Thats why I'm water cooling it to maybe get a another year or so out of it before she retired to my son's rig.

    Waterblock Update: Looped Superposition for 15min

    GPU- High-38c Avg. 36c
    HBM-High- 39c Avg. 38c
    Hot Spot- High 80c Avg. 74c

    P6- 1655mhz @ 1095mv
    P7-1732mhz @ 1180mv
    HBM- 1135mhz @ 1050mv

    Timespy-8,312
    FireStrike-27,047
    FirestrikeUltra-6,394

    Will have to see if I can push it higher. Doubt P7@1750mhz is there but will see how high.

    Why would a fan curve matter on water?

    Update:

    1732mhz seemed to be max card will run...1745 runs but seems unstable... bumped it down to 1712mhz on P7 card still hits 1700mhz in game/benching. What I have noticed now is that HBM can scale up because of temps.
    Was able to push 1200mhz on HBM but at that speed is was hitching. Test it now to see sweet spot.

    To reach more than that you need to registry hack p7 at 1,25v with power play tables.
    And increase power limit too to 200% plus

    The limit on any vega non lc is 1.2v per bios, You have a huge diference from core tempo to hot spot, is your vega molded or unmolded?

    If unmolded be carefull because the cooler can be of the core.

    Yeah... I was reading that people were saying you could mess with Pwr tables and get it to 1250mv but no luck here.. guessing BIOS hard locked. But even raise PL to 150% didnt get me any high stable clocks. I can get 1750mhz on P7 but it driver crashing pretty quick. Guessing I just have an average GPU core.... 1732mhz its top I can get to run stable, but I bumped it down 20mhz to be safe. As far as HBM like I said it will run at 1200mhz but at that speed is was hitching/shuddering. I drop it to 1175mhz and no issues.


    GPU is unmolded. Max air temps were 65c GPU, 68c HBM, and 98c Hot spot. So seeing max 38/39/80 on water is much better. That 80c only happened for once in the run I'd say 99% time Hot spot was 74c or lower.
