Still thinking about a potential driver issue... Because the default adapter always stays at 99% load while the two others go down, then up, than down... like that. Anybody mining on ubuntu 12.04? If so, what driver version are you using?

you might think it's driver but i'm calling Power on this one, either drawing though the PCIe or just right on out of the Kingwing !

your PSU says 1000W right? you know a KingWing isn't going to Run 1000W - you are running 3x cards and a mobo, and a HD?

cya later KingWing, likely the draw on the Pcie is too much , also does it outright just freeze sometimes?

if so that's power , its happened to me , how i actually tested it was to turn my vacume on , it acted like it was drivers , but its a power draw issue.

that's my best guess,

pull one card out and see if it still does it , (or have you done that already? )

so just run two , see what happens.

I returned the KingWing today, I'm getting another one and once it's received, I will then post the results. I am thinking PC Power & Cooling Silencer MK 3 1200w. ~~Not sure if it's worth going with the corsair ax1200wi... it's 40$ more. Still thinking about it. hendo420 also told me about the XFX ProSeries, which I am considering too.~~ Found the corsair ax1200wi for 300$ on NCIX, I'm getting this one. As of now, this rig is not mining until I receive the new psu. Also, I wasn't using powered risers since the motherboard was 3way Crossfire ready, but in my next attempt I will have all cards on powered risers.

That IS a heat problem. If you're reaching that high on stock clocks, then you can't push those cards any further and need some better cooling.

Why would the default adapter work flawlessly then? It is not any cooler than the other 2. I've run those cards to 90+ celcius without seeing throttling on my other rig... But I am looking into trying to have better cooling, I know they are a little hot. I've reapplied thermal paste and removed their plastic cases, which helped them get a couple of degrees.

Thx for your insights!
