Performance breack down 70%

[Sondero]

I don´t have  a 32GB Modul which i can test, and before i order one, i will be sure if i really need it.
And perhabs i will install a 3rd+4th Card in 2 or 3 month, so i have to update to 64GB? 

I also tried "-O" but as you wrote, it doesn´t push the performance for TrueCrypt,...
I looked on at my command,...the "-w 3" was still in my command line, i only forget to post it in the code here in my post

Both card´s are no-founder-Edition (1x Gigabyte Phoenix with 3x fans, 1x Zotac with 2 fans).
The card temperature was round about 40° the room temperature ~20°. The Cards are in an old open Rig like the Ethereum-Mining PC. Amazon-Link to the case

I opend the Task-Manager -> Recource-Monitor   ...but couldn´t detect much action on the SSD ;-/

edit://

actual it runs since ~1h with this datas:

• 480kh/s and 500kh/s
  
• 72° and 67° (Room temperatur ~22°)
  
• CPU usage 2%
  
• RAM 2GB of 16GB in Use
  
• SSD no use
  

so at the moment everything will looks ok,...i have no idea why or at what time the "problem" starts.....the next 2 days i will not be at home, but i hope i runs and will control it via TeamViewer
