i7 4770K overclocking help or educate

I am able to overclock my 4770k "on all cores to 4.2" so I decided to overclock "per core"
I am able to overclock 3 cores to 5.0 and one to 4.2.

My question is in monitoring my core speed in CPU-Z it only reads 4.2MHZ when 3 other cores are 5.0 mhz. Any ideas?
also my voltage is "1.28"
cpu cache ratio is "auto"
Xmp is set "2400"

I dont really think I have a 5.0 mhz 4770k but this is interesting

Any help or educating me on what is happening would be great

Please do the following.


Clear CMOS

In bios set mode of OC to XMP profile.

Multiplier to 42 (you only need to set it in the top rank)

Now wonder over to Digi+ and set LLC to 4

VCore to offset mode
+
0.02

Set your SATA mode if running RAID.

Leave all else on auto.

F10 to save and enter to boot to OS.

Thanks HiVizMan,
I know your very knowledgeable if I could pick your brain with two questions
question about your reply if I would like to try for a high overclock should i only increase the multiplier only?
second question is I am using the formula 6 "ez plug" hopping to add power or performance to my classified gtx 780 any thoughts or info on using the ez plug

if you want to plug it in then do so, it does not harm it.

Ask away.


First question, to increase frequency yes you use the Multiplier only on this platform. You can change BCLK but there is little point beyond fine tuning.

Second question, if your PSU can accommodate the connectors then use them. Not going to make any radical difference to a single card but it will not harm.

So awesome that you guys can overclock your components without worriying about shortening its lives. Once before I had the overclocked machine, used to love it! Now I'm always looking for a longer life span of my components.

Depends on what kind of computer user you are. If your a gamer who wants to play the latest and greatest games at max then your most likely gonna overclock but your also gonna be swapping out parts quite regularly so it really doesn't matter about lifespan beyond 2 or 3 years.

How many decades are you wanting to keep your system for?

OC is in many cases part of the product when you buy an Intel CPU with the K at the end of the model number.
