OCTANE BENCHMARK: Submit performance scores for your rig!

[Seekerfinder]

I set path term power to 1 - this may be the reason.

Sneaky hobbits... so you did. I was looking at the CR only. When you have a moment I would appreciate seeing your path term power 0 score for a more accurate comparison.

Cheers,

Default value of path term power is 0.3 (I assume Bulwerk had this value). Then the score is 41.6 ms/s.

That makes much more sense. Thanks Smicha.

Its like a GPU arms race here! I love it! Gotta say thanks to Smicha and Glimpse for all the input during the research phase of this build.
Also have to thank the guys at Maingear that built this monster and made sure it would not burn its self out. If you want to know more about the build look here http://render.otoy.com/forum/viewtopic.php?f=9&t=43992

Aaaaarrrrgraaaraaarararaaarraaaraaaarrrghh ! That is outerspace joy!
btw: That is +63% compared AC when looking at one Z... and WC can have 4 of those arrrrgraaaraaarararaaarraaaraaaarrrghh !

45-50% is what watercooling gives on 4 cards compared to aircooling (not talking about raisers with more space between cards).

I can clock my strix to 1300mhz and 7000 on memory which gives about 45%-60% speedup depending on aircooled settings. And this is done under 40C on gpus. Once you get watercooled machine you'll never want to go to AC

One Titan Z on Air [However, this is just the beginning - ultimately looking for more than 7 times these scores via WolfPackAlphaCanisLupus1 where all processors - both GPU processors (14) and CPUs (2) - will be swimming in cold water.

2.16 has improved the GTX980's times a bit. All test have CR at 1 and PTP at 1 respectively.

DL - about 33 Ms/sec
PT - about 15.5 Ms/sec
PMC - about 5.06 Ms/sec

7xGTX780TI - no overclocking - air cooled

DL - 168.47 Ms/sec
PT - 136.86 Ms/sec

PathTerm = 1 and Coherent Ratio = 1.
