Hi guys! I've been working on my website, and the most recent addition to it is the RAM timings knowledge base.

I am asking the community to please review this page and add their input on missing (or inaccurate) info.

Here's the link: http://alexanderhuzar.angelfire.com/files/ram_timings.htm

(Sorry for the ads. I can't afford hosting at this time...:shrug:)

It's a rather weak one. I've got a better article and going to improve it further, but it's not in English :D
Can't find time to translate it.

Disappearing posts? I could swear I replied a couple days ago... ehh...whatever...

Anyway...what I'm trying to get at is that I need people's help to complete this chart, maybe add some more timings to the list, and etc. Basically I need a peer review. If you know something I don't, please don't keep it to yourself!

looks like a good start, but remember that when your doing this there are timings that have the same name that minght not do the same thing on all chipsets

and u should add a refrence for setting them since some should be the sum of others + an offset

I've tried to find all the aliases for each timing before publishing the chart. Lemme know if you notice something that I didn't...
and u should add a refrence for setting them since some should be the sum of others + an offsetI have documented the formulas for tRAS and tRC. The Command Rate also has a "formula" but it's more of a rule or a physical limitation of the chipset rather than a limitation of the DIMM itself.

Anyway...if you know of any more formulas or rules, lemme know and I'll add em to the chart!

What I'm still missing:

tREF expanded description?
tRRD detailed description?
tWRWR detailed description?
