I just recently upgraded the RAMM in my wife's PC from DDR2 533 PC-4200 to DDR2 800 PC-6400
Her PC has a Athlon x2 2.4 GHz CPU with a FSB of 2000 MHz
With the PC-4200 installed CPU-Z Reported:
Memory Timings:
DRAM Frequency - 200.9MHz
FSB - DRAM - CPU/5
CAS# Latency - 4
RAS# to CAS# - 4
RAS# Precharge – 4
Cycle Time – 12
Bank Cycle Time – 17
Command Rate – 1T
Since Installing the DDR2 800 it reports the following:
Memory Timings:
DRAM Frequency - 200.9MHz
FSB - DRAM - CPU/5
CAS# Latency - 5
RAS# to CAS# - 5
RAS# Precharge – 5
Cycle Time – 18
Bank Cycle Time – 24
Command Rate – 2T
Have I gained anything? I thought the lower the number the faster.
Under BIOS / DRAM Timings It was set to AUTO. I can change that to MaxMemClock (or something) and have the following options:
DDR 200
DDR 266
DDR 533
DDR 667
DDR 800
CPU-Z Timings Table Under the “SPD†Tab with the DDR2 800 installed
200 MHz 266MHz 400MHz
3.0 4.0 5.0
3 4 5
3 4 5
9 12 18
12 16 23
1.8V 1.8V 1.8V
I can lower the DRAM timings in BIOS and achieve the 3-3-3-9, but wouldn't that be only using half or less of the RAMM potential?
I'm trying to learn and before I posted here I have spent the afternoon Googleing this and that and trying to make since out of all of this. I was just hoping to improve her system some by installing faster RAMM.
Have I gained anything or should I do anything different?
Thank you for your Time,
