OC Ram to 1600 = higher clocks

I have purchased 12gb of adata gaming series ram
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and like all ram they need to be set to the specific timing in bios so i changed the memory frequency to 1600 from 1333. At 1333 the cas latency is at 9-9-9-24 but when i OC to 1600 the cas latency became 9-11-11-29 (using cpu-z)which is slower than its specific timing. Do I have to set each timing individually in bios? if so then how?..because all the memory dram settings can be confusing.

Also what does increasing the memory frequency from 1333mhz to 1600mhz...will it make a difference if i did? Performance wise..cause at stock 1333 and 9-9-9-24 cas already should I even bother OC it to 1600???

The RAM link you listed is for a 8 GB. RAM kit, not 12 GB. If you are mixing RAM even of the same part number you could have issues. Be sure to run Memtest 86+.

Performance wise you're talking ~ 1% system performance by OC'ing to 1600 Mhz. Many mobos default to slower RAM timings when all DIMM slots are used because more time is required for the memory controller to access all DIMMs. You may not be able to overide the BIOS settings - all you can do is try.

It's also worth noting that with DDR3 RAM which is much faster than DDR2/DDR and has wider bandwidth, timing latencies have very little influence on memory performance unlike with DDR2/DDR so don't be concerned with 9-11-11-29 if that's the best you can do as it probably makes less than .5 % difference in performance.

yea its 8gb but i already have 4gb in my pc sorry i didnt mention it...so i shouldnt care if its at 9-9-9-24 at 1333mhz...thats pretty fast already right?
