I have:
Motherboard: MSI 760GM-P34
Processor: AMD FX-6300 Vishera 3.5GHz (4.1GHz Turbo)
Cooling: asetek 510LC CPU Cooler
Ram: Major Brand 8GB (2 x 4GB) DDR3 1600 (PC3 12800) Desktop Memory
(not sure if ram matters here)
Power Supply: GENERIC PS-132-103 800W 80 PLUS Certified Power Supply

I have overclocked before but not when it comes to upping the voltage and I know I need to.
I am trying to get to around 4600mhz but anything pass 4300 my windows won't boot up. I tried upping the voltage to 1.4, turbo off, and then my bios wouldn't boot, I had to take out the battery and put it back to reset to default config so it will boot.

I read somewhere about upping my ram frequency, that may be my issue, and I have no clue what to do for that. After all this im very scared to tinker without advice from some more experienced overclockers. Please, if someone can offer any advice as to what im doing wrong, please do so. Thanks a lot and yes, I know none of you here will be held responsible for whatever may happen.

Currently I have my cpu overclocked to 4300mhz, turbo is off, voltage is on auto, and all else is default. I am worried it's unstable because the voltage may be low set as auto.
Bottom line is, I shouldn't be trying to overclock when I really don't know wtf I am doing. So please, help.

The first thing to know about overclocking is that identical processors yield different results. Your overclock won't be the same as someone else's even if you have exactly the same processor.

The reason that Windows is failing to boot is either due to voltage or the PSU. Have you tried to set your overclock and leave the voltage on auto? You wouldn't want to keep it that way, but it will give you an idea of how much voltage the processor needs, and you can gradually decrease it from there. When your computer becomes unstable, you know that you've gone too far and need to increase the voltage. It's a tedious job, but it gets you the best result.

Your PSU may also be the source of the problem, given that it's a generic brand. I'm quite sceptical about the 800W claim as generic PSUs tend to bloat their numbers in order to look good. How many +12V rails does it have and how much ampere? This should be printed on the PSU itself.

My advice is to first look at the voltage.

Well, I read good reviews on the power supply so I think it's fine but i'll check it later. The problem with voltage is that MSI bios is kinda weird to me. When changing the voltage from auto, I have to use +/-. When pressing the + it's taken off auto and it starts at 1.000. Im not sure what the auto is at because it just says auto. I doubt auto is at 1.000 because I don't think windows would boot with that voltage and clock speed. What about the northbridge voltage and the memory frequency though? Also the OC genie lite on the msi bios auto overclocks for you but when I enable that, windows won't boot up again, freezes at startup.

Wouldn't windows freeze or give me a blue screen because the voltage is too low? It's freezing when I have the voltage at 1.400. I guess I could try like 1.200 or something but like I said, Im scared now because of all the reseting I have been doing, don't want to fry my new computer.

I am kind of thinking now it might be my msi board. I read everywhere that it has a tendency to overheat vrm. My processor has a good cooling unit but my board is all stock stuff, nothing too great keeping it cool other than the top and front fan in my tower.

The board in bios says for voltage that red means it's unsafe and not recommended voltage but it doesn't turn red untill 1.500 so I don't understand why 1.4 isn't working.

Well, my comp just restarted on it's own while watching a simple youtube video. I installed open hardware monitor and speedfan trying to see what my voltage is on my cpu. I didn't do or change anything at all in either of these programs, I was using them for monitor purposes only so I don't think they were the issue. Pretty sure it's because my voltage is too low.

If you leave the voltage at auto you should be able to view it in the BIOS or with a Windows application such as HWMonitor or CPU-Z, although the BIOS will be more accurate. I'd say that a 4.6Ghz overclock on your processor will need around 1.45V. The maximum core voltage is probably around 1.5V which is why you get those warnings. You could go further providing that your cooler is up to the job. Increasing the voltage won't damage your CPU, but the heat from higher voltages will.

There should be no need to change the RAM timings or any voltage other than the CPU core. You can increase the base clock but this also overclocks other components, such as the PCIe lanes, so it's not recommended.

Given that Windows freezes on start-up, I don't think that overheating is a problem. Your rig hasn't been pushed hard enough for a good length of time for heat to build up.

Overclocking is full of trial and error and you won't always get the result you want. If you're worried about damaging your components then stick with a more modest overclock at a lower voltage.

Like I said though, setting my voltage at 1.4 or even higher makes me have to reset my bios to default because it won't boot the bios. I haven't tried lower than 1.4 really... maybe it would work, I don't know but I set to 4100mhz overclock and the auto voltage reads as 1.2375 acording to amd overdrive and core temp software.

4.1Ghz at 1.2375V sounds about right. Most of the time the CPU uses more voltage than it requires, so you could go down to 1.22V or 1.2V. My i5 2500k is 4.2Ghz and 1.2V, but like I said, results will vary.

Going to 4.1Ghz isn't a huge overclock, so you could leave the voltage on auto and be done with it. It's definitely worth your while to get it lower as the temperature will also decrease. Providing that you stick close to or below 70C at full load, you should be fine.

So should I just start upping the clock speed and up the voltage little by little? I am thinking 4400mhz should work at around 1.3 voltage. What do you think?

ok, now im at 4400mhz and 1.3000 volts. Booted up just fine with 1.3000 volts but now I did something different. I disabled Cool and Quiet because I read that it lowers voltage and all this mombo jumbo, basicly it's not for overclocking.

Im sitting at 20c while idle and it seems to go to 40c while playing the game "Smite" Core Temp is showing me that the load is spread pretty good among the cores. nearing 100% load but not quite.

I think I might be bottle necked at this point because of my video card. What do you think? I also have it overclocked but through amd overdrive only because it only has the stock cooler. My frame rate doesn't seem to be going up in State of Decay, stays at around 25-30fps when I was overclocked at 4100mhz and im at 4400mhz. Maybe it's just that 300mhz isn't a big deal but atleast it seems to stay at those frames now. The game use to drop randomly when a lot of stuff would go on but now it never goes below 25fps. What do you think, new video card? any suggestions? not looking to spend 500 bucks.

4.4Ghz at 1.3V sounds good to me, so I'd stick with that. You can gradually decrease the voltage to get lower temperatures, but if you're getting 20C at idle and 40C at load there isn't much point. You still have around 40C headroom.

What GPU do you currently have?

I assume you are talking about my video card? Now I put the xfx r7770 in and im working on overclocking it right now with afterburner and heaven benchmarking. it's running at a stable core clock of 1135mhz. 1145 gave me a bluescreen so I need to up the voltage to get higher. it runs at about 63c temp. I can't really find a solid answer on a safe temp for it. Have any ideas?

You were right though, the r7770 is so much better than the old R7 250. The r7 250 says it's 2gig and the r7770 is 1gig, I don't understand what these numbers are. I assumed the 2gig was better but clearly I was wrong.

Thanks for the tip on changing my video card though, much appreciated.

scratch my previous post. My video card at 1135mhz core clock worked fine in heaven benchmark but anything over the default 1095mhz makes me get a blue screen in the game "State of Decay" not sure what's up with that. Don't use crappy Heaven benchmarking I guess... Use State of Decay :p.

I read up some more on the card and apperently it comes overclocked and 100% stable. Any more than the overclocked 1095mhz will require more voltage and it already has more voltage than the standard issue so the voltage is locked. Theres ways to use 3rd party programs to unlock this but it isn't safe and im happy at my 45-50fps max graphic State of Decay.

Edit: Sorry man. I thought you were the other guy who suggested I switch to my other video card in a different post, lol, very sorry.

Lol, no probs.

The major gains with 2GB are the ability to game across multiple monitors and the increased post-processing capabilities, which is really all about anti-aliasing. Nearly every card these days includes 2GB as standard, and for those that don't, the price difference is usually small enough to justify the extra cash. When I bought my 7850, I had my eye on the 1GB version, but the 2GB was an extra £5 ($10 ish) so that was a no-brainer.

Temperatures around 60C are absolutely fine. I believe that GPUs are much most tolerant to heat than CPUs.

Most GPUs come factory-overclocked. I did up the clock speed on mine with MSI Afterburner but it didn't give me a single extra FPS, so I left it at stock speed to keep the temperature down. The whole 60-FPS-PC-master-race thing is a bit of a joke. I play most of my games at 40-45 FPS at top quality and they're smooth as butter. Trying to achieve an average 60 FPS at top quality in all games will take one hell of a rig. In the case of crappy console ports *cough* GTA IV *cough* it can't be done no matter what you have.
