That would be *very* surprising.

Radeon VIIs do not achieve 3.5 TFlops in homes. They throttle due to heat well before then. I don't see how a Pro model works around this problem.

I finally had time to look at this. You think setting up a wireless card should be easy? Think again. After wasting a few hours, I've given up. I'll probably end up retiring the mobo instead.

I also doubt you get double the TFlops for only 50 watts. Plus, you may have to lower the clock rate to deal with the heat.

I have 2 mobos doing this. My first plan of attack is to try configuring the Asrock h110mitx/ac wireless card to provide internet access instead of the NIC. Fingers crossed.

Ken,

Judging from these flags -DMM_CHAIN=2u -DMM2_CHAIN=3u the exponent is near the upper limits of that FFT length. Our gpuowl defaults may be too aggressive.

Assuming you saved the...

I checked the source for 25.9 and it spits out 3 values. I suspect it has been that way since version 18. I'll check if you'd like.

Does the Haswell PSU have spare 6-pin PCIE plugs? It might make more sense to get a 6-pin to 8-pin converter rather than making the one 8-pin cable drive two GPUs with splitters.

sclk4 = 1547 MHz
sclk3 = 1373 MHz.

At 1200 MCLK, running 2 gpuowl instances I get effective iteration times of 570 and 606 microseconds for a 5M FFT. You can convert that into GHz-days/day.
