Hello all I have not overclocked anything for years so I am a bit out of touch with this sort of thing but I have been having some performance trouble with my ram. What I am aiming for is a stable clock that will provide me with the best performance.

I am having a lot of ram related lag and I was hoping I could get some help to remedy the situation. I have 2x4gb ripsaws 1866 currently running at 1600mhz. I am not sure what to set the manual settings at beyond 9-10-9-28

All of my cooling is stock at the moment and I don't want anything that is going to run hot, just something stable that will utilize my ram better.

Here are the options listed in my bios:
CAS Latency:
RAS to CAS Delay:
RAS PRE Time:
RAS ACT Time:
Read to PRE Time:
RAS to RAS Delay:
Write to Read Delay:
CAS Write Latency:
Write Recovery Time:
REF Cycle Time:
Row Cycle Time:
Read to Write Delay:
Write to Read Delay(DD):
Write to Write Timing:
Read to Read Timing:
Refresh Rate:
Command Rate:

Thank you for those who took the time to read this and even more-so those that took the time to reply.
I will post my results in order to help with others that end up with this combo in the future.

What model CPU and mobo? There's a sticky for setting up 1600 sticks here:

http://www.gskill.us/forum/showthread.php?t=7688

though for your 1866 sticks...at 1600 will prob want the timings at 8-8-8-24 2N, and that will depend on if your CPU can run at 1600

Mobo: Crosshair V Formula http://www.newegg.com/Product/Produc...82E16813131735
AMD Phenom II x4 955 http://www.newegg.com/Product/Produc...82E16819103808

So do you mean I only need to change the timings to 8-8-8-24 and 2N and leave everything else on auto? Also would you mind specifying? I am unfamiliar with the abbreviation 2N.

CAS Latency:8
RAS to CAS Delay:8
RAS PRE Time:8
RAS ACT Time:24
Read to PRE Time:auto
RAS to RAS Delay:auto
Write to Read Delay:auto
CAS Write Latency:auto
Write Recovery Time:auto
REF Cycle Time:auto
Row Cycle Time:auto
Read to Write Delay:auto
Write to Read Delay(DD):auto
Write to Write Timing:auto
Read to Read Timing:auto
Refresh Rate:auto
Command Rate:2N?

Is this correct?

[Tradesman]

From here, it'll depend on if you can get the 955 to run 1600 in a stable state, normally would want a min of a 965 rev C for 1600

[ajilejay]

So if it locks up then take it down to 1333 with the same timing??

*Edit*: Crashed @1666 so I set it @1333 at 8-8-8-24 1N is that correct?

[Tradesman]

See how it goes at 1333/CL8 if stable then you're good...however since you bought the 1866 sticks will prob want the best performance you can get, so could try 1333 at 7-7-7-21 for a boost

[ajilejay]

OK testing it @7/21

[Tradesman]

May check back later tonight if I find wireless somewhere twixt here and Phoenix, otherwise will be back in the AM

[ajilejay]

Seems to be stable

[Tradesman]

Glad to hear it, Enjoy!

[ajilejay]

Yeah thanks for the help, just curious will I be able to run @ 1866 when AMD's bulldozer is released?

[GSKILL TECH]

Yes, no problem at all.

Thank you
