How can i find default advanced memory timings for my ram?

The detection worked fine. Unless the DIMM has EPP profiles, the timings in the SPD are just conservative timings for standard voltages, etc. This post should help you sort things out:

The board officially only supports DDR2 800 so the detection by the mobo was correct. The board read the SPD for the maximum supported speed. You can set it to PC8000 speeds but you will have to change the FSB:MEM ratio in the BIOS. You can either overclock the FSB which will increase the RAM speed, or you can change the divider, either way the mobo is right. Back to your question, CPU-Z will give you a few settings, not all. What do you mean by advanced timings? There are 20-30 timings embedded in memory, DFI is the only board I know of that you can actually get access to all those options.

So what is your question?

You sound like a lawyer attempting to defend a guilty motherboard.

The timings i'm looking for are as follows and these are how the bios has them set.

Trrd 4
Trc 30
Twr 6
Twtr 10
Tref 7.8uS

Cpuz does tell me trc is 30 but none of the rest.

Your RAM is rated for 5-5-5-15 at 500MHz. the numbers refer to CL-tRCD-tRP-tRAS. These are the standard manufacturer advertised settings, everything else is up in the air. TRC is not listed as a rated speed, that one you have to find on your own and refers to Row Cycle time. Trrd is another non rated speed setting and refers to Row to Row delay. Twr is another non rated speed setting and refers to Write recovery time. Twtr is yet another non rated speed setting and refers to Write to Read delay. Tref is, again, not rated and refers to Refresh Period . All the settings you gave us refer to non standard timings. Non standard meaning that manufacturers don't advertise their settings so there is no "correct" setting. These settings you have to fiddle with until you get a balance of stability and speed that you are happy with.

CPU-z is meant to give you a high level overview of your main 5 memory settings. I use A64 tweaker to tweak the rest from windows, otherwise I dig into the BIOS and just try each setting until I find something that works.

It depends on what you tweak. Boosting voltage too high could/will void your warranty. Changing timings should just lead to an unbootable system in the worst case -- no damage to the system or RAM.

Much thanks.
