Crossfired 480's yesterday, Tri-Fire Now? - Page 2

post #11 of 21

So earlier today I decided to go nuts and buy a 3rd RX480. They estimated around 130-150 wattage per card so i figured i could pull 3 of them off without buying a new power supply (750W). I'm too lazy to have to redo cable management so this seemed like a fun test and a time to answer a question that was never asked.

I had some crossfire/trifire issue and 3dmark only used one card. I had to go back to work so i just left the computer idling all day and hoped my house would still be there. It was surprisingly considering the cars idle at 40-45C with the room at 74F

Turned out CCC disabled crossfire so i just re-enabled it and good to go. I ran 3dmark while paying attention to wattage and temps and the max my cards drew EACH was 131 watts. I took a printscreen but lost it during the 3dmark screenshots i was taking for results. Tempatures between all the cards was between 70-80C. Mainly staying in the lower 70's surprisingly. (All stock/automatic settings)

Firestrike Ultra Results:
http://www.3dmark.com/3dm/12832894
SCORE: 6,689
TL;DR: Better then 980s in SLI, 20% faster then 980s in SLI?

Pricing (Micro Center Pricing, Cheapest cards I can find of those types)
3x RX480 - $749

Games that played great no problems with Crossfire and now Trifire in 4K: GTA V, Overwatch, Hearts Of Iron IV
Now gotta install my H115 and some other goodies. Should I even try to Quadfire next? also sorry, no fire.

might as well, just make sure you bump up your PSU if your system starts shutting off with a 4th card tongue.gif

I'd be curious to see your frame times & such from tri & quad fire. As you can tell, my last bout of tri-GPUs(3x gk110) caused me much frustration, and even a slight touch of buyer's remorse for like the first time ever in my life.

I've since redid my rig with a 1080 because of the MB failure on the audio. Rather not take another risk with 480's. They are great cards but i personally had a bad experience that i can't directly prove it was the 480's. But my motherboards audio went out shortly after the 3 way crossfire benchmark. The performance was amazing though.

it's highly probable the PSU had a stroke as well. Even if it didn't hit max wattage & all that jazz.

Wow that really sucks. I'm assuming you just bought the Rampage V10. What board did you have before that? Rampage Extreme V?

This looks like fun! Imagine if multiple GPUs always worked! 3 480 cards vs 1 1080 lol.

How is the middle card getting any air?
post #20 of 21
Thanks for the benchmarks, I've been planning on running 480s in Tri-Fire, but my 980Tis didn't sell fast enough on eBay so I missed out on the initial release, I'm saving up for three when they become readily available now. I'll be purchasing a Wasabi Mango UHD490 here shortly, did you see full utilization of the third card at 4K?
