I have a problem while benching Hynix MFR on LN2 tonight.
Like in post #151 mentioned max on air was around 1710MHz.

I tested with ghetto LN2 RAM pot and temps tested were between -50 and -140?C.
Absolute maximum validation reached is 1748MHz

The most curious thing is, that 1743MHz is 8M and 32M stable.

I tested many things, different BCLK and multipliers, voltages and so on... exact 1745MHz was the end in all combinations.
Tested voltages:
VRAM: 1,75 to 2,1V
VSA: +0,1 to +0,4
IOD: +0,1 to +0,3
IOA: +0,1 to +0,3
PCH1.05: 1.05V to 1.4V
PCH1.5: 1,4V to 1,6V

Do somebody have an advice for me?
I also tried despaired straight the 4000MHz OC profile with 4200 timing preset from Nick - same wall.


Thanks a lot!

if u load the preset , should be fine


1. use cpu ratio x8 , cache ratio x8

2. use internal graphic

3. system agent 0,4 , ioa 0.25 , iod 0.3

4. vcore 1.3 , cache 1.3

5. pch 1.05 ==> 1.3

6. pch 1.5 ==> 1.15

7. internal graphic voltage 1.35

it should be easy to do 3600 at least , unless ur cpu imc has problem.
