here's my question
if i have two of those and a third one that has 2 connectors is it possible to tri-fire? single -> double <- single
where i'll be using the double as the main one (and since ati is not like nvidia which requires both connectors to be used)
How many cards do you have now?

you could get the longer crossfire bridge's like the ones that came with my mobo. that way you would be able to connect it easier with it being off center.

Basically if you use the standard bridge that comes with the Card it might not have complete contact at both ends, or it might not be a complete connection. I can't think of how I could describe it better than basically like having a loose fitting pair of socks. Constantly having to pull them up. In this case constantly having to fiddle with the connector.

I decided to add some mem sinks to my XFX 5770 as it doesn't like the mem to be over 1300 really.

Was going to buy the copper ones with the round bars but decided I could make larger and just as light ones for AUD$2 with a bit of work and the following is what happened.



They were vut by hand with a mini hacksaw so a little sanding was required, also by hand



This is what decided to donate it's life to improve my XFX



I couldn't leave them at their full length but I didn't want to loose the cooling effect so a little idea became a reality



And now because of how the MEM chips are arranged on the card I had to alter the design slighty for 2 of them



For those that were wondering why I had to use 2 different designs



And for the finished result, though not the best picture to show them




I'm still yet to test their performance fully as am going to wait until I hit the 1 million folding points until I start benching again.

Should hit that target in a week so shortly after that I will post the results

Hey since I'm starting to overclock my system now. I planned on doing it with my XFX 5770 XXX too. I got two of then in crossfirex.

So my question. What is the best way and how do you overclock them with it ?
I thought about something like 900/1350-1400

I had the same issue as you. You have two cards with 1 Connector slot, and one with 2 connectors? Well I have the same. I've put them in this order. Single, Dual, Single. But I couldn't still trifire. See the image, if you still don't understand.

Just installed a Hyper 212+ cooler on my Phenom 965 and it dropped the temps nearly 10c at idle and about 8c drop at load. So, I'm really stable and cool at 3.8Ghz now.

Installed some additional fans in my case to try and cool down my 2x5770 vapors but it was no help at all. Looks like nothing is going to cool them down. I ended up having to do a bios flash and force the voltages down to .95 on both cards, which dropped the temps considerably, but forced me to under-clock them a good bit. They won't do 850 core at .95 volts or even at 1.0 but, they are sitting at 800 core with no issues. I haven't tried anything like 820 or 840 yet, so that's on my agenda tomorrow. If I can keep my volts at .95 and get around 820-840 on the core then I'll see if I can take the memory up a bit to at least make up enough to put me back at stock power. Doing this also lets me turn all the fans in my case down to low so it makes for a very quiet system.

i took a few pics to show what i was talking about with the crossfire bridges. first pick is how i have it set up, second is how it could be set up, and the third shows the difference in lengths. sorry for the poor quality pick. cell phone camera. it would be very difficult to hook up the short bridge crooked. i didn't want to push it.

@Freakn-nice job on the heatsinks. let us know how it performs.
