RAM overclock questions

[Denbo1991]

Now, I dont overclock much, only from 2.4Ghz to 2.6Ghz on a 4600X2, but I have a couple questions for future reference.

1. I know what memory dividers do, but I'm not sure how to set them. I'm not quite sure what to look for in the BIOS. There is no specific option that lets me set memory dividers, or maybe I just cant find it. Ill try to get a screenshot of the BIOS if I can (btw, I'm assuming the print screen button doesn't work in the BIOS right?)

2. Is there a chart of RAM timings out there of all the possible/common numbers? I mean, my RAM is set at 4-4-4-12, but can they be 3-4-3-11? or does it have to go down to 3-3-3-9 or whatever? It probably depends on the RAM, but I just want to know if the timings are open, or are there set standards?

Here is a very useful tool that you can use to mix/match your CPU/Memory/HTT.

Sometimes if you look in the online PDF version of your motherboard's manual it'll list every BIOS option
though sometimes the list is incomplete.

Sometimes it doesn't say divider, it could be called multiplier, it could just ask you for the RAM frequency, etc.

The timings e.g. 5-5-5-13 or whatever are independently set from the frequency, though as the frequency
goes up usually there will come a point where you have to use larger numbers in some or all of the
timings to get it to work reliably. The exact frequency and timings that are best depend on your
particular RAM sticks, but you can get overall intuition / guidance from people who have somewhat
similar RAM.
