Faster Folding

[Superman53142]

I was screwing around with BIOS settings yesturday and discovered the following:

Going from CAS 3 to CAS 2 and enabling "Fast Read-Write Turn Around" for the RAM cut my BBAlphaVHT times by almost 5%. I was previously doing a frame in 3:30, now 3:20.

Enabling 4-bank interleave also seems to have some relationship with folding times but I don't have a number on it.

Woohoo! Too bad my memory won't do cas2 :(

Did you try it? Mine's the lowest quality you can buy and I got CAS 2.

I can also go to cas2 with my generic ram almost all ram will do cas2 even if its not supose to.

If I change it to cas2 it will not even POST. I've got Micron pc133 cl3 SDram running at 153Mhz. I don't think it ran cas2 at 133 either.

All depends by yours Fsb, supposed to have a mem module Pc133 Cas3, if you get a Fsb@100Mhz well your mem module works great at Cas2 coz the freq. is lower than the rated, but it's different if you have a Fsb@133Mhz or upper, in this case only the good module works @Cas2, or the module Pc133 or higher rated for Cas2.

That's great news! Tweakin' and seeing your times come down is very rewarding eh? :) Memory is one thing that I've always seemed to skimp on. I've settled for CAS3 for a while but when winter comes..and I'm stuck inside more often..I think it's gonna be upgrade time! FOLD ON!!

Both my RAM sticks (Apacer 128 MB and Veritech 256 MB) can do CAS2 at 144MHz, which I find quite impressive, knowing they are both 133Mhz modules. If I go higher, I have to set it to CAS3 though.
