My System Specs

Default Corsair vengeance timings/frequency

OK, now that I have overclocked my CPU I am on to my RAM. I can honestly say I haven't played with ram much before other than forcing proper speeds/timings etc. I have 2x4gb vengeance rated for 9-9-9-24 @1600mhz using 1.5volts. I am going to be leaving it at 1.5volts, but it is being reported as 1.524v by HWmonitor and CPU-Z.

So far I have set it to vengeance 1866 speeds and to my surprise it worked without issue...9-10-9-27 @1866. I then tried to even it up an 9-9-9-27 and it wouldn't even post.

My question is, which of the timings have a bigger impact on performance (obviously frequency is the biggest impact, but I have already done that and don't think I will get higher without pushing voltage)? Also, it is currently running a command rate of 2T (rated for that stock as well)...is command rate worth tweaking to 1t at the potential sacrifice of other timings/frequency, or just leave it where its at? Would it be worth increasing timings more to say 10-10-10-30 and see if I can get more mhz out of them?

Thanks for you help.

Out of curiousity when you upped the frequency did you use a setting or the blk? frequency?

blk at stock. Changed the multiplier (or ratio...forget the exact term).
