Help me change RAM timings

post #1 of 2
Thread Starter 
To o/c further I need to loosen my RAM timings, but whenever i change anything with the timings in the BIOS the computer doesn't get to post, just beeps a whole lot. In my BIOS it's default at BY SPD and all the timings are AUTO, so I look at cpu-z so see what I should set it to.



Why is Cycle time (Tras) one option in cpu-z but two in my BIOS (cycle time and tras)? My BIOS has:

CAS# Latency
RAS# to CAS# Delay
RAS# Precharge
Precharge Delay (tRAS)
Command Rate
Cycle Time


Looser timings would be 5-5-5-15 right? So I set it to this based off what cpu-z says:

CAS# Latency 5
RAS# to CAS# Delay 5
RAS# Precharge 5
Precharge Delay (tRAS) 15
Command Rate 2T
Cycle Time 22

But it still doesn't get to post, just beeps. Am I changing these correctly? What am I doing wrong?

try setting your ram ratio to 2:3 so that the RAM is running closer to 400MHz and the timings will loosen
