Memory latency & CPUID Question

[new2IT]

I bought some ram that is advertised to run at 4-4-4-12, but I'm not sure what my timings are set to. The PC is an older gateway so I can't change the timings, the bios doesn't even show what they are so I'm using CPUID.

I'm seeing 2 different sets of timings from CPUID; under Timings I have this:

DRAM Frequency - 333MHz
FSB: DRM - 3:5
CAS# Latency (CL) - 5.0 clocks
RAS# to CAS# Delay (tRCD) - 5 clocks
RAS# Precharge (tRP) - 5 clocks
Cycle Time (tRAS) - 12 clocks
Bank Cycle Time (tRC) - 21 clocks

But then under the SPD tab I have these readings for both slot 1 and slot 3:

Frequency - 333MHz
CAS# Latency - 4.0
RAS# to CAS# - 4
RAS# Precharge - 4
tRAS - 12
tRC - 20

So are my timings 5-5-5-12 or 4-4-4-12? Why are there 2 different timing readings on CPUID?

if i recall correctly...

memory tab is the current speed
spd tab just shows the timing table
the timing table speeds are like preset settings for RAM
like the preset setting you have for games, low, medium, high, very high etc...

manufactures have these preset timings so they can get a bigger piece of the market
because not every motherboard can run the RAM at its optimal speeds

If I understand you correctly, basically you are saying the SPD tab is essentially saying what the RAM is capable of, but the memory tab is telling you what your timings are currently set to.

Thanks, I was confused which one to go by.
