BioStar TF7025 Bios mem config

post #1 of 6
Thread Starter 
Was doing my homework and reading the manual b/4 purchase. The adjustments to memory in Bios look a little wierd and out-of-sequence. Made a list of the parameters listed in order. Need help in ascertaining the meaning of some, since only the tech variables are listed.
TwTr 1, 2, 3 command rate?
Trfc 75, 105, 137.5, 195, 327.5 ns bank timing?
Twr 3, 4, 5, 6 ?
Trtp 2, 3 ?
Trc 11-26 total cycle?
Trcd 3, 4, 5, 6 OK
Trrd 2, 3, 4, 5 ?
Trp 3, 4, 5, 6 OK
Tras 5 to 18 OK
One of these is CAS not sure which. Need help deciphering the rest.
Thanx

Check out this article. It helped me out a bit. On page 2 are definitions of some of the acronyms.

Stelth, hopefully I can help you answer your question.

Tcl, Trcd, Trp, and Tras are the most important ones to adjust, unfortuantly I could not find CAS(Tcl) in the TF7025-M2 Manual. So I'm a little confused to why it's not listed in there. So for example, my memory is 2.5-3-3-6. So that would be a CAS(Tcl)of 2.5, Trcd of 3, a Trp of 3 and a Tras of 6. The rest of the settings you could probably keep at auto.

Tcl, Trcd, Trp, Tras and TwTr are explained at this link: http://icrontic.com/articles/a64_overclocking_theory, do a CTRL+F for "Memory Timings".

Hope this helps
