Great one

ethylene(С2H4)?

yes, R1150 (C2H4) 99,99 pure in second stage ..and some more improvment on the XV and evaporator arhitecture ( my own design)to hold much more load than regular used in cascade before , also first stage it use TEV(thermostatich exp valve) not cap tube

Great!!! How much your Cascade costs?

i don´t make units for sale! i don´t know prices , i build this cascade for bench , not just showing low temp thermometer than many builders did.

like i said this cascade use something that other don´t use ...it can hold really load , also DeltaT is very small ( evap base vs chip internal temp)

my K-Typ measure temp directly from evap base witch is have internal hole so reading are very accuraty that you see on the pic. -103`C at ~1.7vgpu , the integrated cascade thermometer measure the suction(top evap) witch is -110 load!

Also a great score without external PWM! GTX260 is suddenly popular!

nice job

thanks , at 1.7+ vgpu ocp will trigger ...so think 1.7v is max that this vrm can do without blew up:D

my card like volts but also is an mediocre gpu , not an golden one

General comment... it's crazy how after all these years, most cards are still "finding" MHz not seen before...or only seen on external PWM.
