i5 2500k p67 overclocking :: vcore problem

post #1 of 3
Thread Starter 
Hello all,

soo i felt it about time to oc my 2500k recently after having it for a while. Too start with i just wanted to do a basic oc of the multiplier & see how my system would handle it (mainly for temps). I have a gigabyte p67x ud3 b3 mobo with non uefi bios flashed to F9.

Pretty much i just dropped 42 into the multiplier & turned off turbo boost. My vcore is in auto so it sets its to 1.320 & the eist setting means in idle my multiplier sits at 16 so its not going full on all the time which is kind of what i wanted & my vcore sits at 1.044 in idle.

My problem is that when i use hwmonitor & cpuz while running prime95 stress test under 100% load the vcore shown in hwm & cpuz doesn't move above 1.052 which i know is too low hence prime95 never gets past 15-20mins. Temps all seem fine to start with but i just cant get my head round why my vcore isn't hitting 1.320 like it should be. I mean which setting is stopping this or is this normal. I can send screenshots if needed>>

Any help would be much appreciated.

for a novice overclock, the only setting you should change is the multiplier, do not mess with any voltages. I would say you should be able to get anywhere between 4.0 and 4.4 without changing the voltage. DO NOT DISABLE Turbo Boost as your PC needs the turbo boost to feed more voltage to your CPU when under load. If anything, leave turbo boost enabled and set the turbo boost voltage to .005 or something. This is usually the first Voltage setting to start raising when overclocking. Raising your multiplier and your turbo boost voltage should make it pretty easy to hit around 4.6 without needing to start messing with other settings.

Ok, but the way i understood my bios settings for turbo boost is that i can set predetermined multipliers depending on the amount of cores being used

e.g. my base cpu clock ratio is 33 // turbo boost is enabled. 4-core is set to 34 // 3-core is set to 35 // 2-core is set to 36 // 1 core is set to 37 // thus turbo boost will increase my multiplier as my cpu usage increases. I also have settings for turbo power limit (watts) & core current limit (amps) which are set at 95 & 97 respectively. This is my standard cpu setup without any playing about.

Where are you getting this turbo boost voltage from because i don't have anything like that in my bios. Like i said before, i'm not changing any voltages. my vcore seems to change dynamically depending on how much i change the multiplier. This makes sense as it is set to auto at the moment.
