Hi all, although I am fairly tech literate I have just stated taking the OCing plunge. I currently have my AMD 6300 running at a stable 4.2 GHz. I have also just received a Kraken G10 to use with a Corsair H55 for my GPU (fun day ahead of me). My question is, does changing the bus speed on the modo make a difference anymore? Back in the 90's and early 2000's changing from 100MHz to say, 200, made a big difference. Still a thing? My mobo is an Asus M5A99X EVO R2.0 and my chipset is currently at 200 MHz. Can and will bumping it higher make a difference?

Erm, AMD is not something I'd overclock. It can be unstable and extremely hot. Intel is better for OC.

Got it. Thanks for the info. I'll stick to the usuals.

disagree... AMD can easily be overclocked. The FX chip is designed to be OCd (or else it would be locked like Intel does) Here are 2 guides but there are TONS more.

have fun, take it slow, and make sure you have a good cooler... and BUS speed is not typically used like it was. At least, not that I have seen while OCing my i5

When I did my OC'ing years back I made a huge list of FSB numbers and started plugging them in and seeing if the PC would post. If it posted then I would use OCCT to test temps and the stability of it. Once I found the max of the chip I then reduced the FSB a bit to help with the longevity of the chip.

Voltage increases might also be needed to attain a higher FSB. I found that often leaving the voltages in auto didnt work the best all the time.

I was also on a water cooled loop, with the CPU, NB/SB, and MOSFETS all cooled with water.

yeah, years ago you needed to... (you may need to now with AMD i dont know) but with Intel, I didnt touch FSB. its at 100. just upped the multiplier and voltage. 4.2Ghz 4670K @ 1.9v

Thanks for all of the replies guys. I actually used the UEFI Bios and let it do its auto thing for a start. The FSB was pushed by the board from 200 to 229 and the cpu multiplier went from 17 to 18.5. This gave me a 4.1 GHz on an AMD 6300 3.5 GHz stock. I tried to push it a bit further but got the big blueSOD when I upped the bus passed 230. Also, I upped the cpu multiplier to 19.5 (4.25 GHz) but it also crashed after about an hour or so. Can this be stabilized by upping the voltage? Voltage makes me nervous (electricity does in general) as it may fry a system. How high should I go safely? Core voltage is currently at 1.275. My board also set my DDR3 2133 to over 2400 with the TPU turned on. Pretty cool setup from ASUS. FYI, I have a H55 water cooler connected to my cpu.

This is kinda fun. Thanks again for your input. There is an overwhelming number of guides out there and it helps to get personnel suggestions.

Just read the guides from Static FX. They really helped with my voltage questions. Thanks FX. If anyone has any other suggestions, I'd love to hear them.

Also, the guides did not mention increasing voltage in relation to bus speed. Will a v increase help with a bus increase? Which v increase do I use?

there is no "releation" as every chip is different. Example, I am 100% stable at 4.2 with 1.9v yet I cant hit 4.4 without going over 2.25 ... where as I know a few people who are at 4.4 with 2.2 or lower volts.

Its a stability issue. If you can boot... run a stress test. If you crash, up the voltage. I do not know the MAX voltage so be carefult to research that first

Also be sure to check and see if you mobo is giving the correct voltage to your RAM. I have had a few boards under volt my ram in the past.
