I might have a try on the OCF and see if it's the same behavior. But I think one of the sticks isn't as good as the other and/or doesn't like the lower temps as much. 15? that's PCH code iirc. Did you insulate the board like in the m8i subzero guide? I think that the pch and vrm don't like to be too cold and the board is so cramped it can be an issue.

Noxinite 200 Posted October 12, 2018 (edited) But only at above 2800C6? Would be very weird. Maybe it was a bclock issue? Edited October 12, 2018 by Noxinite Quote Share this post Link to post Share on other sites

Set Internal PLL Overvoltage to auto, when it's enabled some boards go right to code 15 Edit: from Raja "Just an FYI: Code 15 will also happen if memory is clocked too high for IMC to handle." and "Code 15 means IMC halted before DRAM training even started. Either DRAM is very badly unstable or IMC has an issue (could be IMC voltage needs changing also). Assuming no bent or poorly contacting pins in socket (sometimes CPU might need re-seating)" Edited October 13, 2018 by GtiJason 2 Quote Share this post Link to post Share on other sites

They just kept eating those volts and taking it. Funnily at lower bclock and higher ram divider it wouldn't pass the initial loop compared to passing with wazza at the shown settings. Wow, I don't remember the OCF going up that high on Vdimm! Maybe that's 2.3V + LLC? I need to get out this board again and play with it. 1 Quote Share this post Link to post Share on other sites

I need to get out this board again and play with it. Yeah, she goes to 2.4v without issue. My "test" kit of TridentX sammy hyko has run at 2.4v, and 2.37-38v many times. It needs high vdimm for 2720-2750c8-11-11 & 2933c9-12-12. Test kit because I ran em daily at 2v (2800c9) for over 2 years with little to no degradation edit: think Nox was referring to the Asus Impact vii I sent him, they go to 2.4v too. Also MSI XPower's did too Edited February 4 by GtiJason Quote Share this post Link to post Share on other sites
Noxinite 200 Posted February 4 The earlier posts by me are on Z97 OCF, and later posts are on the Impact. Both do >2.4V DRAM, but the Impact needs LN2 mode flipped for it. 1 Quote Share this post Link to post Share on other sites
