Default Do latencies affect overclocking capability ?

Simple as that, do they, or not ?

Not talking about frequency, just latencies (4-4-4-12 , 5-5-5-15, etc).

Thanks .

Yes. As you increase the frequency you'll have to increase the latency or it will be unstable.

What you mean by correct? If your RAM frequency isn't high, you can tight your timings more. Otherwise, that would only lead to unstable RAM.

Usually, the lower the latencies the higher you can overclock the ram.

You mean the Higher the timmings 5-5-5-15 can overclock over 1066 but 4-4-4-12 usually is around the 800mhz range and if you are lucky up to 900

So dont try to confuse the OP. the correct term is called relaxing or loosening the memory timmings when overclocking. that means going from "TIGHT" aka 4-4-4-12 to looser or relaxed of 5-5-5-15.

I got a question. Every time ive seen timings, theyve been 4-4-4-12, 5-5-5-15, 6-6-6-18. Is the last timing always the sum of the first 3?

No but yes I will look for the formula. They are related.

What the hell I had time and did it. The T'ras:
Quote:
The number of clock cycles required between a bank active command and issuing the precharge command. This is the time needed to internally refresh the row, and overlaps with TRCD. Typically approximately equal to the sum of the previous three numbers.
