Overclocking I7 2600K Help

[Borsuk]

Hello

I search forum and internet to find answer for my problem but i couldnt find any solution, so please dont be angry at me if there is a answer i findnt found. There is alot of errors 404 after so many years passed

My Spec

i7 2600K

Termaltake Contact CPU Cooler + aditional 2 fans ( idling 38C on load about 60C)

MB: MSI P67A--DG65 B3 - i have ver 4,3 bios updated from MSI website from 2013

4x DDR3 kingstone HyperX 4GB 1333MHz

MSI GTX 1070

OCZ 750W power supply

It is old build with bootleneck but it still work fine. Right now i am using it on Genui OC 4,2 GH ( button OC on MB)

I try few guides and even Linus own clip with same board and CPU but i cant  set more then those 4,2GH. If i try set higher i cant start PC it stops after  IDE/SSD screens and reboot

I try 4,5 gh with ram set to 1600 and only ram voltage changed to 1,6408 ( dont have exacly 1,65 in options) like in Linus video and

it doesnt work. I tried lover clock speed but even 4,3GH doesnt work for me. I noticed that after fail reboot RAM speed goes back to 1333.

I watch people overclock this one to 5,1 even but i dont know what i am doing wrong and i ask for your  help and advices

 

Thank you all

You could have a silicon lottery dud, where no matter what you do you won't be able to get more out of it

Try 1.35v core voltage, "Low VDroop" LLC setting and 45x CPU ratio as a starting point.

 

Run stress tests, and increase VCore in 0.005v increments until you're stable or run out of thermal headroom.

First off, if you need this system, I'd reccomend not overclocking such a power hungry chip, many of these and similar boards (including my own) have blown up the VRM's.
2nd off, with manual OC'ing, you need to bump the core voltage a bit to achieve stability at and above 4 GHz. My 2500K was capable of no more than 4.45 GHz @ 1.35 V. YMMV.

 

5.1 is possible with a 2600K in sub-ambient with a ton of voltage. You're not going to hit that. For daily OC, I reccomend a max voltage of 1.35 V for both Ivy and Sandy chips.

 

RAM voltage will not affect CPU core speed. Set ram to 1333 MHz until you get the CPU core stable. There's more to DDR3 overclocking than speed and voltage.

I will listen to you guys and keep it on standard OC. I am planing to buy new CPU, MB and memory this or next year, but now it is bad time to buy enything. BTW as future proof do you think it is OK to use 9 years old power supply ( this OCZ) with new CPU and MB or it tis better to  buy new one?
