GTX 1080 FE slow speed for multiple sha1 hashes
#1
I am running a GTX 1080 Founders Editiion with a +200 Mhz overclock on multiple sha1 hashes.

Can anyone share their speed for doing a similar task?  I ask because I thought this would be faster than the number that I am seeing.  I get close to 1.4 billion hashes per second.

Some numbers from hashcat follow:

Speed.Dev.#1...:  1370.6 MH/s (3105.81ms)
HWMon.Dev.#1...: Temp: 56c Fan: 75% Util:100% Core:2088Mhz Mem:4513Mhz Lanes:16

Are my clocks correct?  Core looks okay, but is Mem?

Some additional notes:
I am running headless with Ubuntu 14 using xdm (per the guide on the wiki how-to) and executed hashcat with the "-w 4" option.
When I run, "./hashcat64.bin --benchmark" with a +200 Mhz overclock, I get close to 9.3 billion hashes per second (this appears to be normal).
My next test will be to run hashcat against a single sha1 hash to see if I get close to 9.4 billion hashes per second.

*Edit*

I have confirmed that for a single hash the speed is correct.  It clocks in at around 9.3 billion hashes per second.
