Dct 0, Dct 1, or Both, Ram timing

post #1 of 8
Thread Starter 
Just got new ram and had to fix up the timing, This bios is different to me for ram timing. For the timing option there is DCT0, DCT1, or Both. All of them let you manually change the ram timing but no clue what the differences are or if it's affecting anything. Currently on Both. Had to adjust tRAS / tRC.

EDIT:

Ok, i have 2 black slots, 2 blue slots. I'm guessing:
Black = DCT0
Blue = DCT1

I have to use the Blue slots due to cpu cooler so i'm guessing just change DCT1 timing?
Please correct me.

you are right, but could be
blue....DCT0
black...DCT1 smile.gif

Change one of them and check with CPU-Z if its OK

Thank you very much. Rept for both.
1 more quick question.
Mobo detected ram @ 9-9-9-28 37tRC
Changed it to what it should be 9-9-9-24 34tRC
So, all i had to change was tRAS and tRC. Is it okay to just leave the rest of them on auto since they are correct 9-9-9? Sorry ram timing is probably my least understanding thing.

Check the RAM sticker for timings and voltage.
If you really want to change something you should do 8-8-8-24 32, but you may need to raise your RAM voltage

Right, i changed it to 9-9-9-24 34 as that is what they are supposed to be. Motherboard detected them as 9-9-9-28 37 though. So they are what they should be now. The question is, is it fine to leave everything else on auto that was already the correct timing. As in i only needed to change tRAS / tRC so everything is still on auto.
