I overclocked my CPU to 3.8ghz and thought I would stress test. I overclocked using these instructions considering I don't know much about over clocking.
AMD FX-6300 overclock settings on stock cooler @ …: http://youtu.be/MsOCEeJ5ZYQ
I used prime95 to stress test and noticed my CPU cores was not holding the max clock speed. They bounced from max of 3.8ghz down to 3.2ghz. I thought the CPU should stay maxed out during this test?

Best solution
FSB (front side buss) is what he refers to. That is usually 800MHz. Your CPU uses that at a particular multiplier. So does the RAM. He changed the FSB from 200 to 217, changing the RAM speed, aswell as the cpu speed. If your RAM is already at max stable speed of 1600, 1736 will most likely be unstable. Best bet is to leave FSB at 200 and just to raise the CPU multiplier under the turbo settings. This will allow the CPU to run at lower clock speeds when not needed, and ramp up to OC speeds when CPU usage is needed, without affecting other components like RAM etc.
Word of caution. OC with a stock cooler is never recommended, stock coolers are designed to cool a CPU at stock speeds, and that's about it. To really OC a 6300, you need a CPU cooler capable of cooling potential greater than the 95w of your CPU. CM Hyper212 Plus or EVO is capable of 180w cooling capacity, which is more than enough to see your 6300 up to 4.4-4.5GHz, or 1.216v I believe it to be.
I'm sorry, but your psu is the next best thing to a boat anchor. Max output on each rail is 18A, 430w max, so continuous is more like 360-370w @12v+. The 3.3 and 5v are huge @ 34 and 36A. Considering the price of the unit, the only way to make a profit would be to use uber-cheap components and under cut every quality corner possible. It's not even capable of meeting 80+ efficiency standards. It's no wonder you are seeing 11.6v readings.
As far as the throttling, likely that was caused by over heating the CPU, which will try and throttle back at first to cut voltage (higher voltage=higher heat) and failing that will just shut down.

Thanks for input on overclocked method. I'll change that. Yeah I was worried about the powers supply. Saw it on list of PSU to avoid somewhere on the net. I keep a good eye on CPU temps. I haven't ever been in too high of a team zone so far. I have a everCool buffalo heat pipe cooler for CPU. Idles at 30c and never gets over 50c range when gaming.

I've still been keeping an eye on voltages while under load. checking HWmonitor after playing bf4 this morning showed a min on 12v to be 11.7v. The 5v min was 4.9v and the 3.3v min was 3.1v. My temps aren't an issue , at least I don't think. not using stock cpu cooler, have a evercool buffalo cooler. not the best but works much better than the amd one that came with cpu. so are these signs that the crappy brand psu just isn't up to powering my setup?

What was max vcore when running 3.8? If it wasn't temps, then your CPU could have been starved for voltage. Should have been @ 1.1ishdamric said:

lol yeah starting to get the picture that the psu is garbage. I know very little about them. figured they gave me a good one for what i wanted to build..Guess not. after looking around the net i see that its not a quality psu. guess it will be next upgrade. single rail better than dual rail and if so why?

Generally go for single rail, especially on low to medium wattage PSUs. High wattage multi-rail is fine if you really know what you are doing and set up each rail's load correctly. There are plenty of good PSUs out there, but there are way more junk PSUs. Just beware, and be sure to ask around about a specific PSU before you make your next purchase.

I would be disabling all power saving options in the bios. CPU spread spectrum and a few other things I would be changing. I jsut cant remember the names. ill post back when i get into my bios
I have the same CPU. and I do notice when I run the stress tests. it jumps between the turbo and base clocks if I dont disable the turbo. is that what's happening? is it dropping below 3.5ghz? or is it going 4.1... down to 3.5 ?
