Nist5 Power Efficiency

[bensam123]

So I'm a miner and hopped on the nist5 bandwagon. I'm not sure who came up with the power numbers, but they appear to be wrong. Using a kill-a-watt meter my power usage has increased. One of my systems I have the meter hooked up to has 5x r9-280s. x11 - ~910w, x13 - ~910w, x15 - ~905w, nist5 - ~980w. I'm using the same clocks and power settings across all of those.

I'm currently using the sgminer build from the icebergcoin thread and getting around 12mhs per card on nist5. Is this what other people are getting?

the low power efficiency was a "feature" of the old amd drivers where the hashrate on groestl was pretty bad.
If you were trying to put an iceberg near a gpu farm running nist5, he would melt very fast

Yes I finally got my lazy ass to test out the power consumption and I can confirm on my end that Nist5 use more power than x11 and x15. I think I'm going to stop mining nist15 now.

4 x 280x on x11/x13 - roughly between 610 - 640 watts  ( using pcCoolers's mod version )
4 x 280x on nist5     - roughly between 720 - 735 watts  ( using talkcoin-miner from iceberg thread )

[SpeedDemon13]

Only thing I see that is power efficient is the ratio of hashrate per watt, but otherwise it runs hotter/higher wattage than X11,X13,X15, Hefty-1 and other algos.

My post from other threads

6 Days straight so far, no issues here. X11mod

280x > 270 > 270 > 270



Sapphire 280X w/ Stilt BIOS Dual-X Windows 8.1 x64, 14.6 Drivers @ 1150 mV using TRIXX. My card is stubborn so that's why it's only hashing at that rate. And yes I think I'm using sgminer version from the first post, I don't remember

First values are the 280x

"intensity" : "18,17,17,17",
"thread-concurrency" : "8192,6401,6401,6401",
"lookup-gap" : "2",
"gpu-threads" : "2",
"worksize" : "256,128,128,128",
"expiry" : "1",
"queue" : "1",
"gpu-engine" : "1120,1120,1120,1110",
"gpu-memclock" : "1500,1500,1500,1500",

Here is NIST5

I'm pulling 585 Watts, reading via my Kill-A-Watt. I'm pulling less power on NIST5 than X11, and my configs are the same. My Kill-A-Watt doesn't lie

I always though nist5 have lower energy usage then the rest. Did you increase the clock or something?

[Fioravante]

What voltage you got on the core? That may be the reason.

I also can confirm NIST5 uses both more wattage and more amperage in my readings. My temperatures were also slightly higher. I would see a gain of 60-85 watt per 4 card rig. All of my rigs are undervolted through BIOS mod so that shouldn't have been a factor in my readings. I may get 150 Mh/s total with NIST5 but I don't think many of the coins are worth it quite yet to switch algorithms.

Same here. About 5-8% more.
