Hi Guys, I'm having some trouble OCíng my 4690k on my z97-ud5h motherboard (hence the title). After a failed overclock the system wont recover (easily). It wil not enter the bios, lost its bootdrive and when i finaly can enter the bios after multiple reboots, no previously tested OC is stable. (loading its saved preset) Only when i take the PSU offgrid and do a full bios clear i can dial in my previously tested OC, The full 10h straight Prime95 small FFT stable. Its getting a pretty annoying and long process this way. Am i missing something? I tested this with multiple PSU's alongside my current one (Antec TP650 and Corsair CX600M), Different memsticks, remounts, latest bios. In short, i did a lot.. As i'm quite an experienced user/overclocker, please do get technical if you need to. My actual achieved stable OC sofar: 4690k @ 100,05 x 43 (4300Mhz) Kingston fury 2x 8gb Ram: 2133c11 Vcore: 1,215v Vrin: 1,9v vRing: 1,15v SA: +0,1v Vram: 1,65v Phase en Loadline: extreme perf Eist en C-states are off' Thank you in advance! PS, English is not my native language, sorry for any inconvenience.
