i7 non k overclocking

[christian franca]

i'm overclocking my i7 4770 non k in my msi z97 mb, my goal is reach the cinebench score of the i7-4770k. atm my i7 is running at 4030 mhz and i can archieve 784 the k version run at 4400 mhz and get a score of 822.

so with that i made this proportion         4030(my actual frequency):784(my cinebench score)= X(supposed mhz to archieve k score): 822(cinebench k score)

i got 4225 mhz and that's the clock i have to archieve in my cpu 

have this any sense? please help before i burn my pc lol

You can try bumping up the base clock but it's not recommended. Any reason you need an oc apart from chasing numbers?

Also these cpu's are not meant to be oc'd and you lack a lot of fine tuning on a non k as you are basically forcing it to run at a higher speed so don't be surprised if it doesn't work. It can also damage your cpu or motherboard if temps, voltage,... get out of hand.

There are some issues with baseclock overclocking haswell processors on Z97 and Z87. Basically, in simple terms, the baseclock is tied to more than just processor speed. When you overclock the bclk you're also overclocking the memory, sata, and pcie (not 100% on pcie). This often will cause instabilities and problems in other parts of the system that were not initially intended to be messed with. For that reason, multiplier overclocking is the only really recommendable overclocking on intel cpus for many generations predating Skylake. Skylake is different, because the baseclock was unhooked from the rest of the system. Sadly for you and haswell, the bclk is still very much tied to the rest of the system on haswell.

Yea... don’t overclock via bclk. Most I would so is 101 or 102, and even if you get that to work, the gain is so negligible it wouldn’t be worth it.

Unless your BIOS has options to lock the clock of the other systems, you'll end up overclocking every other bus in the system (as @Founders mentioned). Last time I tried on Haswell (with a 4670k and a Z87 motherboard) I couldn't pass 104 base clock (so a 4% increase).

i where at 103.34 mhz bclk (4030mhz) for reach the theoretical 4225mhz of the cpu i have to reach 107.99mhz bclk

multiplier x39

check the math

That looks way over what’s possible to achieve on bclk oc. If you really want to play with oc try to get k series cpu and than oc as far as possible but safely.
