I just replaced my existing memory with a new Crucial Ballistix kit containing two 1 GB sticks of DDR500, PC4000 memory. This memory is also advertised at 3-4-4-8.
Am I correct in assuming that 3-4-4-8 means the following?
CAS Latency Time: 3
RAS to CAS Delay: 4
RAS # Precharge: 4
Cycle Time: 8
I am questioning this becauase the bios in my Abit mobo lists the following in the order shown:
CAS Latency Time: 3
ACT to Precharge Delay: 7
DRAM RAS # to CAS # Delay: 3
DRAM RAS # Precharge: 3
The numbers indicated above are the automatic SPD settings.
Since the the order and terminology used by the bios is apparently different from the "standard" notation, I want to be sure I am properly setting these parameters. I also want to verify that "Cycle Time" is the same as "ACT to Precharge Delay".
I am running a 250 MHz FSB. With my old memory I used a 5:4 ratio to prevent overclocking the memory. If I try overclocking the new memory with a 1:1 ratio, the machine eventually locks up. I suspect this is due to the faster SPD bios automatic settings and the 3-4-4-8 specified for the new memory. Before I start changing these setting I want to be sure I know what parameters I am really changing.
