The timings are the 3-6-6-10 group. There are others in newer mobos, but these would do for now. To "loosen" them means to increase them. Here's a draw as to what each timing represents to find them easier in the BIOS.



The idea is to set the group to 3-6-6-10 BEFORE upping the FSB. The memory has to be "relaxed" before pushing it higher. It's like throwing ballast overboard before accelerating.

If it's not enough up the ram voltage to 2.9V, but only if with the loosed timings it still doesn't work.

So basically i have to lower the timings before I increase the FSB? is that correct?

Not quite, you have to "loosen" them <=> to increase them.

Ex. 2-3-3-5 unstable OC could give a 3-6-6-10 stable OC

For the record:

Loosening = increasing values (like from 2-3-3-6 to 3-5-5-8)

Thightening = decreasing values (like from 3-5-5-8 to 2-3-3-6)

Loosening means your ram has to do less work at the frequency it's set at
Thightening mean more work at the same frequency.

So in theory you can loosen timings to allow an increased frequency

That seems really wierd, shouldnt it be the other way around??


oh and btw: i set the timings higher the other day and it wouldnt even fire up. I had to take a stick out (was using 2x256Mb sticks) reset the timings, then put it back in. why is that?

FYI: i cant remember the timings. I think it was something like 9-3-3-5 or something like that

That'll work

And if it was 9-3-3-5 it really would'nt work, because a 9 CAS is of the chart for most rams.

Look mate, you could be making some research before OCing. We can give you some pointers, but you should know that there is all the difference in the world between 9-6-6-3 and 3-6-6-9.

If you download a program called CPUz (free) and look at the second page (mem timings) we see what's the CAS, tRD, tRCD, and tRF. With them we can see what there's to be done.

Im actually reading that link from tlan at the moment, explaining timings. And as far as the CPUz shot goes, thats going to be a few weeks. I didnt get the ram on friday as i had hoped, and now i have to wait 3 weeks coz my mate is selling me his car real cheap, and that comes first as far as i m concerned. But as soon as i get the ram, ill take the screeny and post it.
