I have an fx-8350, gigabyte 990a-ud3p, and some gskill memory I can't remember exactly but it advertised 1866mhz. I'm in the process of overclocking my cpu.

If the cpu is at stock clocks and I bring the ram to 1866mhz instead of 1600 I run into problems like crashes. I currently have my cpu at 4.3ghz which brought my memory clock to 1720mhz and it works fine, but if I bring the clock up to 4.4ghz and 1760mhz then I get a worker failure in prime95 and a crash on startup with gta 5. Because of the problems at stock cpu clocks with memory frequency, I think the memory is the problem. But the intervals for system memory multiplier aren't precise enough to get to 1600. It's either way down low at 14xxmhz or too high at 17xx.

The memory manufacturer told someone on a forum that to get 1866mhz they need to add .05-.1v to nb, which I did and it didn't work. So what do I do... Overclock the cpu and have the memory clock really low, over clock the cpu and add more voltage to north bridge? I'm lost.
 
Solution
Look for EOCP or XMP in the BIOS and use it to set the DRAM to 1866 - if problems add + 0.05 to the DRAM voltage and set the CPU/NB voltage to 1.2

You mean return cpu clocks to stock and work with just ram? But when I overclock cpu it changes ram speed...

Just overclocking to 4.3 somehow gave me a pretty big performance boost in gta 5, and it wasn't placebo. It's a cheap CPU and I have a massive cooler so I don't see a problem. I didn't drop extra money on this cooler for nothing.

Oh as in the ratio, which is doing exactly what you're describing.

I also stream using the cpu because the built in AMD codec doesn't seem to work so extra cpu speed helps with that too. It's also just fun to tinker with this stuff... But don't worry, I'm very careful with over volting.
