Memory overclocking question?

[RLX7]

I have 2 128MB Premier system sticks of PC-133 CAS2 and I've heard about this 1-1-1 thing and 2-2-2 thing. What's the deal, and how do i set this? I have a KT7 and a Duron 650@900. What exactly does this do anyway? Thanks!

there is no such thing as 1-1-1 timing not that i have heard of

there is 2-2-2 timing though

these timing allows more memory bandwith which helps when u have a fast system

But how do you change this in BIOS?

Pull out your Abit Manual It will help you a little. Go into your bios under advanced chipset i beleave and find Sdram cycle length and set it to 2 then go to dram bank interleave and set to 4.then depending on your ram set dram timing mine is set to turbo but only good ram will run at cas2 turbo. good luck

I'm curious as to hat the 2-2-2 actually means. Thanks for the info on the BIOS man. I'll try it and let you all know. Does doing this help benchmarks in sandra?

Yes! Especially the 4-way interleave. You might want to uprgrade your bios to the latest beta (wz01), since it fixed some problems with these settings (normal, fast, turbo), when running cas2.

RLX7,
i to have been searching for the awnser to the ram timeing question, i too have an abit socket-a board and ram that suports 2-2-2. unfortunaly, no one seems to realy know, they just tell you to turn up everything with the bios. from what i understand it seems to be that dynamic ram is made of columns and rows of infmation, data is accessed from the column and then must be refreshed throught the row. in this situatuion you have a cas(column address strobe) latency and a ras(row address strobe) precharge time, i belive there is also a ras to cas delay.
what i just decribed i found about two weeks ago in various articals on the net that i found with google serch. i am by no means an electrical enginer and could be wrong on any of it; i just wanted to thow out what i have heard to get the disscsion flowing.
