Crucial Ballistix 2x1GB timings

[nWoVance]

alright guys im a n00b at overclocking memory, so i need your help on timings if you wouldent mind guys/girls

i dont want to destroy my lovely new ram because my knowledge is subsequently insufficient.

basically when you guys go "my ram is 4-4-4-12"

im confused as to which timings you guys/girls are referring too, theres seems to be alot of different options on my motherboard as to which i dont understand.

heres a picture i took with my phone lol to let you guys/girls take a look at.

From the forum's sticky:

CAS (Column Address Strobe or Column Address Select) - is the number of clock cycles (or Ticks, denoted with T) between the issuance of the READ command and when the data arrives at the data bus. Memory can be visualized as a table of cell locations and the CAS delay is invoked every time the column changes, which is more often than row changing.

tRP (RAS Precharge Delay) - is the speed or length of time that it takes DRAM to terminate one row access and start another. In simpler terms, it means switching memory banks.

tRCD (RAS (Row Access Strobe) to CAS delay) - As it says it's the time between RAS and CAS access, ie. the delay between when a memory bank is activated to when a read/write command is sent to that bank. Picture an Excel spreadsheet with a number across the top and along the left side. They numbers down the left side represent the Rows and the numbers across the top represent the Columns. The time it would take you, for example, to move down to Row 20 and across to Column 20 is RAS to CAS.

tRAS (Active to Precharge or Active Precharge Delay) - controls the length of the delay between the activation and precharge commands ---- basically how long after activation can the access cycle be started again. This influences row activation time which is taken into account when memory has hit the last column in a specific row, or when an entirely different memory location is requested.

thanks very much resoluteK, now before i decide to indulge in tampering with my timings
i'd like to know if i need to tamper with any of the other "many" timings.
and erm since were on the subject im having confusion with my new ram and cpu
it seems "since" i have installed my new ram it doesnt seem to let me overclock my CPU
the overclock option is still there but when i go to overclock it says CPU,PCI 33.33mhz
now before it just said my CPU 323x9 and i could basically fiddle with this easily to overclock i dont understand how to overclock anymore, or even if its possible.

thanks very much for your help.
ps vance.

I'm not familiar with your motherboard and its bios settings, but there is often an overarching overclocking option that adjusts between default, auto, and manual overclocking. Make sure this is on manual.

By the way, I recommend setting your ram settings to auto until your determine your max cpu and fsb overclock. Then determine the fastest ram settings that are stable at your max fsb.

yes its a shame but i have actually checked every single bios setting on my motherboard and it seems it is randomly allowing me to overclock and sometimes not i set my ram to 233/533mhz and it let me overclock again but after i rebooting the option disappeared again lol maybe my bios needs updating i'll give it a check
