settings for 2500 K at 5.2Ghz

[stephanisk]

Let me introduce myself. I am not new to overclocking but pushing this 2500K to over 5 ghz stable is being a little challenge.

My system:
i5 2500 K
GA z68 ud7 b3 bios f11a


My cooling system consists of one TEC chiller, my waterloop only for cpu runs at -8 degrees and is powered by a seperate meanwell power supply, so temps are not the problem for the moment

My ram, graphic cards, and hdd and aqauero are all watercooled on ambient temperature

Now my question?

Does anyone have settings for an overclock at 5.2 ghz :

My settings for a stable 5.0 ghz are:

- Multi steps load line at level 6
- Vcore at 1.475 now
- Qpi VTT voltage (1.050 normal) now set to 1.22
- System Agent Voltage (0.925 normal) now set to 0.925
- pch core (1.050 normal ) now set to 1.10
- cpu pll ( 1.800 normal ) now set to 1.9
- dram voltage at 1.68 ( for mushkin ram at stock 1.65 1600mhz @ 1866 9 9 9 27

Anyone has working settings of Vcore for a 5.2 speed, i can make it boot with vcore 1.56 but running prime after few minutes crashes

Thanks for all help

hey, 5 ghz i hit, no problem it is above 5 it gets really messy, my temps at 5 under load dont come over 50 degrees, at 1.6 vcore i come to 72 degrees or something, but it still crashes while i think vcore is enough it is the other voltage that cause the problem i guess, that is why i ask here.

but thanks, i watch the video, always cool to see it hit over 5 ghz

Hey, nobody has tried a 5.2 oc on a 2500k, i can not believe it ))

im gonna guess less than 5% of 2500k's will hit 5.1ghz at 1.475v core under full load. your gonna have to be way higher, like 1.55v to get that high. not all 2500k's will do 5.2ghz no matter how much voltage and cooling and uber nice motherboard you have. maybe 60% of them can. whats the bin on your chip? you can look it up and get an idea of how far you might be able to push it. like 2000 of them are of the 2 bin codes that hit 5.8-6.0ghz.

-Hi thx for your reply :

I am still trying to get a stable clock. I have already tried at 1.7 vcore and it remains crashing. I can always boot to windows even at 5.5 GHz but prime crashes after 5 minutes. 5.4 boots to windows on 1.56 vcore.

I am wondering if it is not another voltage that cant keep up and that it ia not vcore that ia the bottleneck? Anybody has an idea on this?

Current settings that maintain stable for about 7 minutes in prime
Multi steps load line at level 7
- Vcore at 1.590 now
- Qpi VTT voltage (1.050 normal) now set to 1.38
- System Agent Voltage (0.925 normal) now set to 0.985
- pch core (1.050 normal ) now set to 1.16
- cpu pll ( 1.800 normal ) now set to 1.96
- dram voltage at 1.68 ( for mushkin ram at stock 1.65 1600mhz

there is such a thing as too much vcore. having the qpivtt above 1.22 is not going to help. return your ram to stock 1333mhz clocks.

what does hwmonitor say your voltage is when under load in prime? use intel burn test set to maximum stress level to quickly test your chip. prime you can use for 12 hours after you can get the the 30min intel burn test.
