Anyone have a Overclocking Guide for 860k?

[tkvbeek]

Hi, I want to overclock my cpu but don't know what voltage I should run it at. Anyone got any ideas on what voltage to run my 860k at for overclocking? Im looking to get somewhere around 4.2 ghz. Thanks

Here are my specs -
AMD 860k
Gigabyte F2A78M-D3H (rev 4.0)
EVGA 600W PSU
EVGA GTX 750 ti
8gb Corsair Vengeance RAM

Basic overclocking with that CPU is done by increasing the CPU's clock multiplier. As you make incremental increases and test for stability and temp, it will eventually produce an unstable result. That is when you will need to increase the vcore (CPU voltage) in as small an increment as possible to regain stability. You may then be able to increase the multi more. I like to disable turbo mode before starting to OC along with C&Q and C1e.

Be sure you have a good aftermarket cooler before you begin. And don't take the vcore much above 1.5v (AMD recommended max). Remember... the lower the vcore, the longer the CPU longevity.

Is there any way that I should be testing it for stability? Or should I just log on and play around for a bit to see if it's alright? I'm very new to the whole overclocking deal but I'd like to figure it out.

Most folks use Prime95 and run it for 30 minutes to as long as over night. https://www.mersenne.org/download/
If it passes that, it is good. Myself, I'm not that fussy. I run Intel Burn Test http://www.majorgeeks.com/files/details/intelburntest.html
...for its default 10-pass run and if it passes, I'm happy. IBT will be quick and allow you to go back and make adjustments w/o spending all your time waiting for a long stress test to complete.

Another way to go is using AMD Overdrive: http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/over-drive
That lets you set your multi and voltage right in the program for testing w/o having to constantly boot to and from BIOS. It has a built-in stress test too. And you can watch temps in the form of thermal margins. TM reads the inverse of core temp. I.E. as TM decreases, core temp is increasing.

If you're not all that particular and your temps are OK, you can just skip the stress testing completely, and just run your most CPU-demanding game and see if it crashes or not.

Alright thanks, I'll work on that. I'll probably end up turning the cpu up without touching voltage first and see if itll run a game fine and all. Is that okay to do? And is there any other settings i need to worry about?

Increasing the CPI multi alone is fine. Once you get to an unstable result, then you can decide if you prefer to back off to the last stable result and live with that... or start raising the vcore to regain stability and repeat.

Increasing the FSB ratio will overclock all of the hardware on the motherboard, and this yields better results if one knows what they are doing.

1. Increase the FSB in increments of 4.
2. Test the computer after each increase.
3. DIMM, NB, and SB all need to have their voltage set to the recommended settings.
4. Keep in mind the DIMM's clock needs to be reduced since it will be increased by the FSB ratio.
5. Do not increase the FSB ratio and multiplier at the same time.

Yeah, I'll give that a look into, right now I'm only really concerned with the cpu but yeah, I'll check that out. This is my first time overclocking so I don't want anything too difficult quite yet.
