@gpufreak - What are you using to cool this unit? I see the hoses so assume liquid. What is your setup? Hardware/etc.

You can see the current cool-rig in action at https://www.youtube.com/watch?v=hUtHhNO5Y3o

8x 7990, 8x FC-WB (Nickel), 9x 360 XTX, 27x Typhoon, 7.5L coolant.

I will be upgrading this set to: 14x 360 XTX, 42x Typhoon, 40-45L coolant so stay tuned Smile

may I ask what params you used? I'm only getting ~88% utilization for NTLM <sad_panda />

Hi epixoip, impressive speed, congrats!

Can you share bit more about your setup, drivers, (clock)settings, version of hashcat :-) ?

Wow. But that's just 50 seconds... are you able to cool it enough to keep that speed forever?

i have yet to get these cards over 72C! but that said, i do get asic hangs at 1200 Mhz at stock voltage. need to adjust the voltage a tick to make them stable.

Did you bump memory clock too or is that less important?

epixoip

12-30-2013, 05:53 AM
yeah in the benchmarks i did, i tested at a memory clock of 1375 since that is the 7970's default memory clock. not sure if you've seen those or not yet, but i posted a link on twitter.
