Overclocking G3258 Help

[hccard]

After a lot of research and seeking help on the forums, I finally was able to start testing the overclocking waters. I've been messing around with it for the last few hours, I've read some guides (notably this one: watched some videos, but I still have a few questions. My components are as follows:

 

-Gigabyte B85-DS3H-A Motherboard

-Pentium G3258 CPU

-Hyper 212 EVO CPU Cooler

 

At the moment, I've got the g3258 running at 4.2GHz, but the settings concerning my voltages appear to be high, and if I try to take any of them down just a little bit, I get blue screens while stress testing using Prime95. I can boot at 4.4GHz, but it quickly crashes under stress. My Uncore (AKA Ring Bus or Cache) Ratio is set at 3.50GHz. My CPU VRIN Voltage is at 1.900V, CPU Vcore Voltage is at 1.30v, and the CPU Ring (AKA Uncore or Cache) Voltage is at 1.149V (which appears to be the limit for my motherboard). Temps are fine under load. Those are the only settings in my BIOS that I've modified. Does anyone have any suggestions or tips as to how I may continue to push the Clock Ratio on my CPU with turning up the voltage seriously high? Or is it that I just got a bad chip, or that the Ring Voltage limit on my motherboard is holding me back? Or should I just be happy with my current configuration? In this video:

, the guy is using the same motherboard and recommends setting the Uncore Ratio to 100MHz below the Core Ratio. Is it possible to increase the frequency of my core by raising the Uncore ratio? All the guides I read seem to suggest keeping it at the stock ratio...

 

Another odd thing to add, I downloaded Gigabyte's EasyTune program, which is supposed to provide an "auto tuned" overclock and for some reason it set the Core Frequency to 4.0GHz, but undervolted the CPU VCore Voltage to under 1V. It also raised the CPU Ring Voltage to 1.149V (as high as it'll go), but I was unable to tell what the Ratio had been set to. I would like to note however that my system was able to boot with this config, but almost immediately crashed once loading the desktop.

Here is my G3258 at 4.5GHz with auto voltage. No blue screen and temps are 'ok' with a cheap Siedon (same price as a EVO).

 

-edit- and im sure i could manually lower the voltage for better temps....js

That's a pretty decent chip. I had a similar post today about my friends g3258. He was getting 4.3ghz at 1.3v completely stable, 4.4 at the same voltage would crash on boot.

A 1.2ghz overclock is really good. I would say leave it where it is

4.3ghz at 1.3v is losing the silicon lottery...I know my chip is at 1.275 @ 4.2 on the stock cooler

 

 

(most chips can get 4.5ghz @ 1.3)

Oops. I was told otherwise yesterday...

I updated the OP to hopefully provide some better insight.
