Are my memory timings optimal?

[discy]

I have a kingston valueram KVR1333D3N9K2/4G. Specifications here: http://www.valueram.com/datasheets/KVR1333D3N9K2_4G.pdf

I've overclocked my system and could only let the memory run at 1200MHZ or 1500MHZ. Since I have 1333 memory, I choose for 1200MHZ.

CPU-Z tells me I have the following memory timings:

DRAM Frequency: 600.0MHZ

FSBRAM: 2:8

CAS# Latency (CL): 8.0

RAS# to CAS# Delay (tRCD) 8.0

RAS# Precharge (tRP): 8.0

Cycle Time (tRAS): 22

Row Refresh Cycle Time (tRFC): 67

Command Rate (CR): 1T

Since i've never fiddled with the memory timings; I wonder if these are the optimal settings or which I should change in order to get better performance.

Only you know if they are the best you can acheive dude.

I've read some websites about memory timings but I have no idea with which setting I should start, which settings may influence others and what a common goal is to reach on budget memory.

Also I pressed a "mem-ok" button on my mainboard after installing the memory because it didn't boot. The mem-ok button makes sure a setting is used that works with all types of memory; i would like to know if my settings are obvisouly slower than they could be, and how to find out what they should be.
