Help me w/ these mysterious BIOS settings

[Oni]

I know that these settings have something to do w/ the memory timings, but I'm not sure what. I'm currently running an Asus A7V266-E RAID.

The first setting is:

DDR_1T/2T_ITEM
--1T CMD
--2T CMD
--AUTO MODE

The second setting is:

DRAM 4K/8K PAGE ENABLE
--AUTO
--4K Page Enable
--8K Page Enable

If somebody could tell me what these do, and how they affect RAM timings, I'd be truely greatful.

I believe that the first setting changes the CAS setting for your RAM. 2T = CAS 2

The second setting though.... I have no clue.

i agree with JigPu and i think the second may has something to do with the page closing policy described here (http://www.rojakpot.com/Speed_Demonz/BIOS_Guide/BIOS_Guide_02g.htm).

Can you tell me where exactly on the page?

Oni, the 1st option is otherwise known as the command rate. it decides whether the Dram commands are issued with a wait state of 2 cycles or 1. 1 offers a decent bump in performance, but is a hard setting to run. a lot of ram (like my crucuial) cant handle 1T command.

the other has something to do with the size of the Data blocks (maybe:confused: ) that are moved in and out. all boardds have similar settings, i just always leave mine on auto:D

Ok, thx!
