I figured now is as good a time as any to start testing. I spent the day testing 4 of my better blocks against the DD Maze 4.
Test Bench:
Epox 8K7A
XP1700+ @ 1500+ speed 1.55Vcore
VIA 2600 pump
Cheapo Multi meter with Type K thermocouplers. 1 mounted under CPU and one for water temp.
Small heater core with Delta 120mm fan at 5Volts.
CPUBurn running K7Burn for 1.5 hours per block. 1/2 hour warm up and 1 hour of manual temp logging taking an average for the end result.
Water temp was 24C for all blocks.
Yes the test system sucks but got to start somewhere. Better test bench under construction.
