Ok, I read this:
http://www.tomshardware.com/answers/id-1832520/asus-m5a99fx-pro-amd-8350-skill-ripjaws-1866.html

Pretty much my issue. I am trying to overclock to a simple 4.4 for now. Works fine if I keep ram/memory on auto and not force 1866 and timing....but i'm worried about timing being an issue while gaming, it is showing 11 cas latency. as soon as I retry this oc and add the ram changes it goes to a system check and doesnt wanna go to windows.
I did do
1 enabling DOCP in the BIOS pick 1866 and then raise the DRAM voltage...same
2 Auto fill all and raised the CPU-NB Voltage +0.1V to give the CPU memory controller a boost

I do have an extra set of G.skill Ripjaws X Series DDR3 1600 (PC3 12800) 8-8-8-24
wILL THIS ONE WORK BETTER W/ MY MOBO THEN THE 1866 SNIPER?


Case- NZXT Phantom w/ 3x200mm 2x140mm 3x120mm fans
Mobo- m5a99fx pro r2.0
Ram- G.SKILL Sniper Series 16GB DDR3 1866 9-10-9-28
CPU- FX-8350 cooled with H80i with Noctua NF-F12 fans
GPU- EVGA GTX 780 FTW 980MHz x2 SLI
PSU- EVGA SuperNOVA 1000 G2 80 PLUS GOLD Certified 1000W

Hey custom, so sorry I haven't been online all day and didn't see your message or post, but if you figured it all out I'm glad you broke through with it, great job!!! I've never actually touched my RAM when overclocking all that much though. The most I've done is make sure that it's performing at the speed advertised. I've never spent time going into the timings so I don't think I would've been of much help to you. Sorry, if I would've seen your post I would've researched it too and tried to find you a solution. Besides, solving a...


With that clock speed at that voltage and temperature you should have quite a bit of headroom to overclock it even further. You can be patient and bump it up a step at a time (increase clock and give it more voltage if it fails) until you reach around 1.45-1.5v or just plug and chug big numbers and work backwards, although working up slowly will show you clearly the limits of your card when bumping up voltage doesn't help or when temps get too high. And I actually set my NB to auto because I never really looked into it, didn't want to mess with the board too much. So, sorry, but I'm not much help there. Good luck with it and, as always, let me know if you need someone to think to :)
 
Just to update....... I installed the 300rpm Noctua's and have it stable (I hope) at 4.7ghz but I had to bump the volts on cpu up a bit and tweak a couple of other things in bios. it, at first, passed for a little and then then started to error. I adjusted cpu and ram volts and i might of adjusted nb too. can't remember....I will post pics of bios when i'm done for others in need of help looking at this. Been running prime for a while now with temps averaging 53 and peaked at 62 degrees. CPU-z says 1.48v but I can't remember exactly what I set it too in bios.
