**[Official]]** ASRock z87 OC Formula + (M) Thread

[loopy83]

Hey all together...

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!
Andi
