Hi,
I have a Z68ap-d3 rev 2.0, i5 2500k, 8GB Ripjaw 2133Mhz cas 13.
Using the latest award bios 'FD' my memory (F3-17000CL11D) x2 4gb sticks will run at 1600Mhz only, overclocking is fine at 1600mhz (down to timings 7-8-7-20 1T) @1.6v. As soon as I try use 1800Mhz/ 2133Mhz (at loose timings, i get no post). (XMP profiles 1 or 2 also don't post)
I then updated the bios to the beta U9 UEFi bios and both XMP profiles work correctly for 2133mhz and manual settings at 2133mhz.
I don't want to keep the UEFI bios though as the vdroop for the VCore is huge and there is no load line settings. with the award bios i can OC to 4.6 with low voltage, using the UEFI bios I have vdroop of 0.2v and an unstable over clock.
I have re flashed back to award bios and i'm running the memory at 1600Mhz, could i have some support regarding this issue please, it seems like a bios issue to me, i would like to run Award bios with memory going above 1600mhz or my XMP profiles to work or UEFI bios with some sort of load line setting to limit the Vdroop.
Note i have taken the cmos battery out and power lead overnight, this doesnt solve the issue.
Another issue I find is artifacts on the screen when booting into windows with Award bios (overclock is 100% OCCT and Prime stable), i turn my monitor off and then back on then the artifacts are gone until the next reboot..... With the UEFI bios i get no artifacts.
Thanks
