    PLE has completely removed the reference 6800 cards from their website now, I wonder if they intend on filling existing orders or whether I'll be getting a refund.

    I just want a card dammit.

    cyberporn is the most unoptimised game of the decade so i doubt they even knew they did it.

    I don't think that's it, RT enabled titles were making nvidia cards look shit all by themselves years before AMD stepped up to the plate with their own solution.

    Unoptimised is the most overused and misunderstood term of the decade.

    Just a reminder. CDPR have been down and dirty with Nvidia for a long time...

    Nvidia don't care if it hurts their performance, as long as the competition is hurt even more. They are Dogs!

    My block on the way for reference 6800. Will let you know but I doubt it'll arrive this year

    I hope so - I am relying on procuring a reference 6800 XT to fit in my NCase M1! Hopefully there will be decent stock early next year, at the moment these cards just don't exist.

    My ID cooling 120mm thin fans have arrived. I am hoping I can slip these underneath the 6800 in my ncase.

    Eventually I want to go to 2x240mm rads and a water block on the 6800 in the ncase.

    Anyone having issues with a 6800 crashing in an NCase?

    I got a feeling it has to do with airflow. Even with the side case off. Either that or my PSU is struggling.
    I've now fitted 2 x 120mm fans intaking from the bottom, but I only have 1 free fan header.

    Really need a V6 vented panel for these cards.. unfortunately all sold out.

    What do you have for a PSU? Logging temperatures will show if they are getting out of hand.

    Fan splitter will take care of your lack of headers.

    I've been using FanControl and it works really great

    I have a massive Corsair 450w SFX driving a 5950x, 64GB ram and a 6800.. So I am probably close to maxing that out.
    Yes, I need a fan splitter, my motherboard sysfan header doesn't fit the fan connector, but the FAN header does.

    The 120mm slims help, because the graphic card fans weren't powerful enough to actually suck air into the case, particularly with a 2 slot card, the fans are too far away from the case. The exhaust heat from the card would just hit the side wall and circulate around.

    Well a 5950x can pull 250w+ with a heavy load and generous PBO limits and the 6800 has a 250w TDP so yeah that's where I would start looking...

    Yeah 450w on a 5950x & a 6800, you're well over the rating and should probably stop using it until you get a new PSU. It's putting to much stress on the PSU and it'll could fry it. PSUs are usually under rated by at least 100w but even then your well outside of it's efficiency range.

    Don't mess around with your power supplies guys, over rate them by at least 30% of your full load, preferably 50%. The single most important thing is your PSU, if you load it down to much and it goes pop, they usually take everything out.

    As a general rule most power supplies are at there peak efficiency around 40 - 60% load so for a 450w you'd be looking at around 200 - 250w load max to keep it efficient.

    That's a good point, not just frying your PSU, but taking out all the expensive bits. Think of all the magic smoke you'd be letting escape. It's criminal.

    Hence why even though I have an 850w PSU atm, I'm moving to a 1200w once it arrives. I don't even trust an older 850w with my 3080, 5900x, 64gb, and nvme x4 drive. Need to be over specced, not under.
