Issues with overclocking Haswell i5 4670k with MSI Z87 G45, help please!

post #1 of 4
Thread Starter 
So after recently purchasing an MSI Geforce GTX 1070 (upgrading from a GTX 760) and obtaining a Acer 27" 165hz G-Sync Monitor I have noticed some issues with hitting max fps in some of my games. The monitor is 1440p but even so In games like Dota 2 and Overwatch I am struggling to keep top fps in either game. Overwatch my fps stays around 80ish on average while Dota it stays between 100-120 but I'm a bit surprised especially in Dota that I'm not able to get 165. I've been using the built in OC Genie to overclock my i5 4670k to 4ghz and that gave it a noticeable boost but I'd like to bump it up a bit more. I know they are capable of much higher, on average being 4.5ghz. Since I'm pretty confident my CPU is limiting my fps in my games I figure if I can get a little more juice out of it I'll be golden for another year or two until I maybe replace the mobo/cpu/case/ram. Here is my build.




Intel Core i5-4670K 3.4GHz Quad-Core Processor

Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler

MSI Z87-G45 Gaming ATX LGA1150 Motherboard



G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory
$69.99

G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory

MSI GeForce GTX 1070 8GB Video Card


Samsung 840 EVO 500GB 2.5" Solid State Drive


Cooler Master HAF 922 ATX Mid Tower Case


EVGA 850W 80+ Gold Certified Fully-Modular ATX Power Supply


Acer XB271HU bmiprz 27.0" 165Hz Monitor


Asus PB258Q 25.0" 60Hz Monitor







I tried following some guides on here and on youtube for my exact mobo/cpu combination but every time I bump it higher than 4.0 I get a blue screen or a couple times as it started to reboot it said the OC failed immediately at a black screen. I was able to obtain 4.0 without OC Genie just fine but 4.2-4.4 I barely ever made it into Windows.

Help me!

When you go above 4.2GHz dont use OC genie as it usually overehootrd the needed CPU voltage or it doesn't provide enough voltage to be stable.

Did you try increasing the CPU voltage when aiming for 4.5GHz? Maybe you did not put enough CPU voltage. Maybe try something around 1.25-1.35v @ 4.5GHz.

Thanks for responding. Sorry I didnt clarify, I did not use OC genie when i was trying to overclock besides when i was originally using the preset 4ghz. I dont even think it lets me change things off it, its more of a full preset for easy 4ghz OC. I tried upping the voltage but not as much as you suggested. Is it safe to run it at 1.35v? Would you suggest me setting it at that first, making sure it works, and then slowly lowering the voltage until it crashes to test where i should keep it? If i can get 4.4-4.5 Id be happy, right now with the genie OC at 4GHZ it idles around 40C and when gaming it only gets up to 62c so it should be good for more OC I would think.

Also, I don't think I'm running the newest bios. Will that make a major impact? I"ve seen some say yes and some say no. So far the easy 4ghz OC has treated me well with great temperatures.
