Question about RAM Speeds

post #1 of 5
Thread Starter 
Hi experts,

Anyone know why the RAM speeds are different? They are the same model and I can't find anything in the BIOS that sets RAM speeds different for different ram slots

That's the Serial Presence Detect (SPD) information from the RAM.

These are what the RAM reports it can do.... this is NOT what the RAM is actually set to. If you plug in RAM and didn't touch any settings, the motherboard would default to one of these configurations.

To see your RAM configuration, go to the "RAM" tab. The RAM timing, voltage, and timings are always the same for all modules.

Oh I see,
just found it weird because they are both basically the same part no. but the max bandwidth is different

Anyway my NB frequency fluctuates between 800.1 and 3200.5. Is that normal?

You didn't list the type of system you are using.

Basically, there is no more North Bridge. That value is probably the system or CPU base clock. This value changes if the CPU is set to lower clock speeds to save power when not in heavy use.
