ASUS M5A99FX PRO with FX-8350

I am relatively inexperienced when it comes to overclocking and was hoping someone could help me figure out a correct overclock for my new ASUS M5A99FX PRO R2.0 motherboard with an AMD FX-8350. I also bought 16 GB of G.Skill F3-2133C9D-16GXH Ripjaws X Series (2x8gb) DDR3 which I have seen multiple posts saying it has to be manually set and I am not really sure how to properly do that as well.

Any help would be appreciated with tips, settings, frequencies, etc. I don't want to push the processor too hard, maybe from 4.0 to 4.4 or so, but I do want to get the RAM to 2133mhz O.C. at the advertised timings if possible, so I need to know what settings I need to adjust for the CPU/RAM within the bios.

Thanks!

Daniel

The FX-8350 is unlocked so overclocking is relatively easy. It already runs at 4GHz stock so I would just raise the multiplier a few notches, disabling any features such as C1E. I like to leave turbo on a few hundred MHz higher but that's up to you.
The listed memory has been tested to run at 9-11-11-31 2N @ 1.6v so I'd keep it around that.

The guide that I used to assist my overclocking, also keep in mind, with some FX setups like mine, the only way to get quad memory at 1600mhz or higher was to set the CPU/NB voltage WAY low and match the CPU/NB frequency with the RAM frequency.

As a sidenote, FX 8350's IMC should only handle 1600mhz ram in Quad channel. You can run a higher frequency with 2 sticks but 1600 will be your max with 4. You may be able to achieve more by manually overclocking the RAM but I doubt it. Have you checked your bios to see where your motherboard sets the RAM frequency?

I only bought 2 sticks of the G.Skill ram, 2x8GB for 16gb, so I am hoping I can get it up to 2133 mhz?

Thanks for all of the replies everyone, I could use some additional information like what all settings/features I need to disable and what I need to set the frequencies at

If you have 2 sticks you should be good to run at that frequency (Sorry didn't notice that in your original post). Read those guides and they'll walk you through what settings to have turned off. Typically all power saving options should be disabled, along with Turbo core, PCI spread spectrum.

I had someone told me they get better results upping the bus speed instead of the multiplier, which do you suggest? I also have to manually OC and set the RAM, so I am not sure which would be the best route and do not know much about doing the RAM either.

I didn't consider overclocking my 8350 easy, even though it is unlocked that simply means it will be overclockable to a higher frequency. For instance Intel's i5 3570 is overclockable, just not as high as the 3570k.

As far as your question is concerned it all depends on your cpu, some people have had better luck upping the bus, other just the multiplier, for myself it took only the multiplier because my RAM wouldn't run above 1600mhz, and once the FSB is upped it is upping the RAM freq., and NB freq.

I would follow the general guide for overclocking the 8350 and if you have issues you can try a different combination.

I have a 8350 on a crosshair v formula z. I purchased 2133 patriot black mamba dual channel. I simply set them 2133 in bios and changed timing(11-11-11-30) and it had no issues completely reliable. The right ram will overclock well. The corsair 1866 ram I originally got would not go past 1600 reliable. Depends on the ram. bus overclock is what I plan on doing, then the ram might have to be detuned a little for stability.
