Anyway, ok. We will start from there. Set everything how it is to the guide (first page) as much as you can. Only things that are different is that PLL Overvoltage should be enabled, turbo ratio 42, and vcore to 1.20. Boot up and tell me what you get.
1 thing I need to know though, what is your desired OC?
Ok. I followed your instructions on the first page and i get 1.264 vcore @ 4.2ghz. When i manually set the voltage to 1.200, i get 1.160 @ 4.2ghz.
Ok, a few things I need to know from you!
1. What is your desired OC?
2. What is your max vcore?
3. What cooling do you have?
4. Are you willing to be patient? I only help those who want to be helped and patience is key!

Second I am in need of some help with my OC mainly because of my MB which is a Biostar TZ77XE3. I am trying for a 4.5GHz OC which I can get stable with two different setups in the bios, first way is using fixed mode for the Vcore and having it set at 1.270V but in order for this to work I have to disable the CPU Vcore Loadline. Because if I leave it enabled I have to use 1.340V to have it run stable, also while I was doing all of my testing starting from stock settings up to the 4.5GHz I seen that in fixed mode while lets say set to 4.2GHz with the Vcore set to 1.200V it would show that voltage until I ran the test then it would drop to 1.152V through out the testing. But if I then turned off the Vcore Loadline it would stay at what I put it at.
The next setting that I could get to run stable was in offset mode at + 0.100V with the fixed set at 1.250V factory default and Loadline enabled. Which would get me at 1.340V max.
All my testing was done with Intel burn, prime 95, and aida 64 while using core temps, cpu-z, and cpuid for monitering tools.
Through all of the testing my temps never went past 73C max even at 1.340V.
So if anyone could please help me out with this I would greatlly appreciate it, and this is my first time overclocking so sorry for being a noobie here but there is not alot of info out there on OC with biostar MB.
I can help you to a limit. I have personally never bought a Biostar mobo but I'm guessing you have the essential overclocking features. First things first:
1. Set LLC to Ultra High (75%)
2. Set vcore to manual 1.25000
3. Set multi to 42 (4.2GHz)
4. Set RAM to 1333 9-9-9-24 2T
5. Only use prime95, CPU-Z, and CoreTemp. (I don't like the other programs so just limit yourself to these for now)
