Overclocking Issues

[Dransk]

Hello forum Iwould like some help with my system here are specs:

Cpu- pentium g3258 clocked at 4.344 GHZ

Cooler- Deepcool Captain 240

Storage-120g ssd,2 tb hard drive, 1 tb harddrive

motherboard- msi sli krait edition

Gpu- galaxy gtx 770

Ram- 8 gb

power supply- corsair cx600m

case- deepcool tesseract sw

2 sp120's case fans

The issue i have is when i overclock my cpu (Pentium G3258) above exactly 4.2Ghz then my system will not boot, Im not sure if it is voltage or something please help me. Here are some screenshots of my bios:

How are you overclocking? BLCK or Multiplier?

I am overclocking through BLCK

This will alter other things like your Ram speeds etc so if you have no idea how to overclock several things at once without providing them all with voltage increases your motherboard, ram and so on will fail to boot.

Sorry i mean multiplier but even when i go up to 4.223 it will fail to boot

Possible your CPU needs more VCORE Voltage.

Your voltage is still set to auto, and it's awfully low for 4.2 GHz. My G3258 needed a little over 1.2v (if I recall correctly) to hit 4.2. Your vCore, by comparison, is only 1.064v. I'd bump the voltage up, no question about it. If it doesn't boot at 4.2 GHz with a vCore of 1.064, try bumping it up in .025v increments until it's booted, running and stable.

Thank you I will try that however, I am not sure how to change the voltage of my CPU on the krait bios settings. Can you please help, it was a lot easier on this gigabyte board I used once

It's pretty simple in that BIOS. See where it says "CPU Core Voltage"? Click on "Auto" and change it to "Override", then enter the voltage you want to use in there. I recommend bumping it to 1.1v, then going in .025v increments from there to get yourself stable. If you're oh-so-close to stability at a given voltage, particularly as you climb north of 1.2v, you can try playing with the VCCIN, system agent and I/O voltages a bit--we'll cross that bridge when you come to it.

 

Another thing you can do to help early on is to go back up to your CPU multiplier, and in a box below that, you should see "CPU Cache Ratio", or something similar. Setting it to 33 could buy you a little added stability while you test, then bring it up from there.

 

The "safe" max voltage for Haswell chips is 1.3v, but if your load temperatures are staying well below 80C, you could conceivably push as high as 1.4v at risk of degrading your CPU over time.

Thank you aisle9 I will try that when I get to my pc. I like your profile image as well
