well my RAMs are already 2400mhz and CAS10. i was just testing to see if they are stable with my OCed cpu. and seems they are not right now.

its currently running on 1.65v. can i tighten its timings by increasing the voltage.? maybe 1.75v or higher. i wanna reach CAS9

Maybe, but if your RAM is stable at stock CPU settings, then it's not a RAM issue. It's an IMC issue

then i will change back to my stock settings and tighten my timings first. then re-do my OC and try to stabilize it

I'm confused because in this thread they suggest to raise to +0.15 ? Auto is unstable ? that is the problem! Right now I have +0.15 SA and auto for digital and analog, my ram though is only set to 1600 mhz as of right now, and i'm stable, i'm not sure changing the 0.15 will change much. Since lowering to 1600 mhz Ive been more stable than ever, i'm a little disappointed 1866 is a bit to aggressive even with 0.15+, but ill have to stick with 1600 mhz for now.

That's kinda crazy. Are you validating this with benchmarks? Cinebench r15, Maxxmem, x264 bench, etc

This is what I have been trying to tell him.

@Jedson Adding that to system agent (SA) was just to see if it was an issue. If it didn't help, turn it back to auto as it is most likely not the problem in your case. As I mentioned, it would most likely not help but worth a look at.

As for performance. Core is the best and 1600 ram is fine with good timings. If you can get your 1600 to cas 7 and + 1 multi, you would see more gains than just going to 1866 with softer times in the 10's.

Okay am I harming anything by leaving System agent to 0.15 + ? I have not noticed any increase in temperatures. Stability feels a bit improved actually. I followed SIN's guide because I have gigabyte. He reccomends to set it there. I'm going to follow his advice because he knows a lot about gigabyte boards. I followed his template overclock.

Im still not sure about which one to go with. low cas low Mhz or high mhz high cas

and whats the safe zone for ram voltages. currently im running them at 1.67v

That's the problem with this forum. If you do a search in thus very forum you will get totally different answers. I've been yelled at for recommended lower timings, and that rated speeds will give better performance.

Normally lower cas means ram will be faster. Higher MHz more performance, but if you have high cas it won't be fast.
