Help needed with CPU overclocking

[fluffeeey]

hello, im very new to overclocking just got a hyper evo 212 for my i5 760.

 

I managed to overclock to @3.62GHz with a voltage offset of 0,0625 and memory to 1378MHz (stock 1333mhz)

Temps were good, never exceeding over 50 degrees celsius

 

I tried to go for 4GHz, but all i got when i tried to boot up was Preparing automatic repair. I upped the voltage, even downclocking my memory to 1036mhz because I saw it was running at 1.77 Volts.

 

Nothing worked though for me, tried 3.8 and that didn't work either. My question is if a 3.6GHz overclock with a voltage offset of 0,00625 is any good? And if i could improve it, as my temps were good. I got a p7h55/usb3 ASUS motherboard

Thanks in advance

You should never overclock two things at once. Did you try slowing going to 4.0 or did you just straight to 4.0 and fail

Depends on what the stock voltage was, .00625 is pretty low really, idk if you got that right. Try setting the voltage to manual and locked, and set around 1.3v for an i5 760 on a 212 EVO. DDR3 is fine to run at 1.77, although it's on the high side, remember to increase the IMC's voltage too.

As I increase the BLCK frequency, the RAM increases as well. I went for 3.62GHZ, went fine. Then tried 4.0, failed. Backed down to 3.8 and failed again even though I increased the offset to 0.125.

You're right. I meant 0,0625. I'd rather not set the voltage to manual as it's locked then and the CPU will run hotter and draw more power. I've read that when you use a offset the voltage can still dynamically change, I think. What does the IMC voltage do though?

Running the CPU at a fixed voltage really isn't bad, the CPU will only switch the transistors when it has work to do generally. But it's fine to use an offset, however for extreme or heavy overclocking it isn't that suitable, use CPUz to get an idea of what thr load voltage is and keep upping it until you hit a thermal or power limit. the IMC is the integrated memory controller, its the part of the CPU the RAM speaks to, as you push higher memory OCs that too will need to go up, a good voltage for that is 1.175 usually, but I push 1.2 through my kaby lake chip. There are other things to consider too but they're not important for a 4GHz chip running on LGA 1156
