Hi,

I've just upgrade to an i5-4670K with the intention of OC'ing.

I'd like you opinions on if it's worth it. I'm asking as my stock settings of 3.4GHz (Turbo 3.8GHz) returns a score of 10300 on 3D Mark Basic and if I OC using MSI OC Genie 4 to 4.2GHz that score only Rises 10650. Is the extra 10 degrees in temperature worth such a minimal increase? Or am I looking at this all wrong?

Or is it simply that I need to OverClock using the BIOS as that will show better results?

I am new to OC'ing and have read quite a lot of info but still don't seem to understand fully. I apologise!

Any help or opinions will be appreciated.

This is my set-up:
i5-4670K w/ Phanteks PH-TC14PE Cooler
MSI MPower MAX
Kingston DDR3 8GB 1333MHz
Gigabyte HD7950 WF3 OC (Stock @ 1000/1250)
Corsair HX850 PSU
Seagate Barracuda 1TB HDD

Firstly overclocking with software is garbage. Overclock through the BIOS only.

That's a pretty good cooler you should be able to hit 4.4 with reasonably temps.

I have a 4670k at 4.2 and it's running pretty well. I get Low-mid 70s running prime95 and during games it only hits in the mid 50s. Mind you I'm not the most hardcore overclocker either

For temperatures I get worried if it's constantly pushing past 85 and upwards. If you're in the 70's then you don't need to worry this chip can take that.

Ok, thanks for the advice, I'll give it a shot. One thing I'd like to check is the voltage. Is there a ratio, a certain amount I should up the voltage by for each 50MHz increase? Or doesn't it work like that? Just got to try and error my way?

Finally to what's the best way/software to test the OverClock? I have Intel XTU and 3D Mark. Would either of these suffice or would you recommend something else?

I'm not going to explain this very well but this is what I did for 4.2.

I actually used the turbo to 4.2 setting in my bios to set some of the basic changes it does so that you cpu can overclock, you can change some of the things it does yourself but seeing I'm still going to control the important stuff, I figure this is more convenient.

Set the multiplier to 42 and the cache ratio 39 (its been suggested ti keep this 3 away from the clock ratio). I set my voltage to 1.2 cache voltage the same and input voltage to 1.9

Test with prime95 or AIDA64 or intelburntest. I usually use prime 95 and select the one that does most heat. If it crashes quickly then bump your main voltage up 0.01 until it gets stable. When its stable run it for a few hours and make sure that it's stable and temperatures are acceptable
