I am still planning to tweak a couple of things, but I think changing my ram timing from 1T to 2T really helped sort it out.<br><br>
I am also considering a future drop of PLL voltage from 1.7 to 1.5 and staying around there to see if ivy likes the lower vcore there, which I have heard it does.
Well I think my board is dying.
I've been trying to get UEFI to work with my video card (7870 Myst, which should support it). After flashing numerous video bioses and never getting past a black screen/unlit keyboard when EFI Option Rom was enabled in BIOS, I decided to give up. I reset my CMOS due to black screen problem, but it isn't showing my integrated graphics anymore (the menu option for IGFX is gone). I also noticed it now detects my 16GB of RAM as 8GB, and even worse, my 2500K has a LOCKED multiplier (won't let me set above 33, I was stable at 45 +0.060 votes for 6 years). It won't boot with no external video card (red light by the slot), and with it, the IGFX options in BIOS are gone.
I verified all sticks of RAM I have are functioning one-at-a-time (besides, it would be odd for 2 sticks to just die). But if all four are in, the red MemTest light comes on. The RAM also shows up in the SPD checker.
Not sure what to do. I have a P8Z68 Gen3 non-Pro. It sucks because it's not like they sell LGA1155 boards these days to replace it, even though my RAM and CPU are probably fine.
So now I went from 4.5Ghz and 16GB of RAM, to 3.3Ghz and 8GB. I even tried reflashing the current BIOS just in case, but that didn't help anything either. If anyone has ran into this problem and found a solution, I'd like to hear it.
