It's my virgin post on Overclock.net and also my first time overclocking a machine, (let alone building a machine). I own an z87 MPower fitted w/ i5-4670k & H100i
There's not much buzz for this motherboard series in the local forums I regularly visit (at least I haven't come across one yet) so don't mind me dropping by here.
I've read the MSI guides, a couple of generic Haswell guides, tips and comments from all over and while some are confusing, I've come to an understanding to modify values of the CPU Core Multiplier and the Vcore.
So here's the thing:
I've come to a point where I'm able to get 4.6GHz using 1.24V. Tests using AIDA64 and IETU for about 8 hours showed this was stable & temps were fine at 60+ full load, however there were two random instances where I ended up with BSOD while gaming on BF3 on ultra. I increased the Vcore to 1.25V and there hasn't been any BSOD since.
However, I want to keep the Vcore at 1.24V and use it for 24/7 operations while I explore higher clock speeds.
That's when I turned to VCCIN, Ring Ratio & Ring Voltage. Previously they were on auto, so I pumped in exact values as those from core with VCCIN at 1.8V. When I ran AIDA64, my screen suddenly froze several minutes in and the only way was to hard reset.
I thought I should increase VCCIN to 1.9V and so I did, but it made no difference. Should I be pumping this higher or am I doing something wrong here?
By the way, I left the CPU Core Ratio & Vcore on "Auto" although I did input the numbers. Is that the right way or I'm supposed to change to another mode? Why I ask is because sometimes for Vcore especially, I see that on HWMonitor it doesn't reflect 1.240V but probably 1.230+V.
