Thread: UD3R + Crossfire problems




  1. #1

    Default UD3R + Crossfire problems

    Just bought 2x hd 5770 and tried to install them but they wont fit properly.

    Attachment 2838

    1. I tried using slot 1 and 3 which worked but the first card was over 100C after some testing and I didn't get any good results. Tried FFXIV benchmark and went from 2200 points with 4870 to 2300 with dual hd 5770, probably due to the overheating.

    2. I would like to use slot 2 and 4 but the PSU is to fat, I can't even fit the card there.

    The optimal result would be to use 2 and 3,5 (the pci slot)....

    Any suggestions how to fix this?
    I thought about the following:
    * Change gpu cooler to something smaller
    * Get some kind of riser card?
    * get a thinner PSU?
    * change case :(

    theres no real fix other than set the psu up outside of the case at the back or buy a case where the psu sits at the top,other option would be to trade both 5770's in for one single 5870 card which should give you the same scores as 2 5770's,if you did change your case maksure it has enough room below the mb and extra slots at the back to fiit dual slot gpu inside esp when using the lowest pci-e slot,if i were you i would set up the psu outside the case temprorary and use slot 2/4

    Yeah well I guess the easiest solution would be to change for a hd 5870 just a few more bucks. Just sent the store an email and asked if I oculd exchange them for a Sapphire Radeon HD5870 Vapor-X HDMI DisplayPort Dual-DVI 1GB

    Is the H50 set to intake or exhust? Why would the 1st card heat more the the 2nd?
    Are you sure they were working as crossfired?

    First card would always be hotter as it is the main card, and it's near the NB and above the second card.

    You could either switch to a single card as mentioned above, or as you mentioned buy an aftermarket thinner cooler for one or both of the cards.

    Chike: my h50 is set to intake then a noctua fan on top as exhaust. Reason why the first card was so damn hot was probably because the fan didn't have any room, it was almost touching the card in slot 3.

    I ran the same benchmark with a single card and got 2400 points so that was better than in crossfire and it just went up to 70C instead of 100C.

    I check out some third party coolers but they are humongous or watercooled and I don't want to start a watercooling project just for the VGA cards :)

    you need to space the cards out more like this but your psu being bottom mounted is stopping you

    <object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/TXwIF0S8Gzc?fs=1&amp;hl=en_GB"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/TXwIF0S8Gzc?fs=1&amp;hl=en_GB" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>

    + some gpu benching software wont recognize crossfire,cinebench wont see two cards either,you should see 50% even 90% in some games improvement with 2 cards as those models scale well in xfire,do you have fraps? tested with that in games?

    I don't doubt that the improvement would be good but if I can't use it due to space problems then it wont help me :P I tried it in a game that I play daily and it worked but I noticed some stuttering, probably because of the overheating.

    I have to say that I think the Mb placement of the pci-e slots is kinda stupid, the only way you can use 3 way SLI which they advertise on the box is if you have 3 very thin cards/water cooled and not have a bottom mounted PSU. Most of the cards nowadays takes 2 slots and is actively cooled with fans, and that wouldn't work on the ud3r even with a bigger case/top mounted psu.

    Can you add a fan blowing into the inner space somewhere in your case? If so that would be great and probably help a lot, maybe a 120MM mounted near the front CD/DVD drive bay area blowing straight between them and out the rear of the case.

    Have you tried using only one card? Just to make sure it is the spacing that cause the heat and not the case ventilation.
