Windows can't tell what type of memory you have, so no. What CPU / FSB are you running with that board?

 

Thank you for the answer. My CPU is an Intel P4 1.80A Northwood, FSB400.

If the FSB of your CPU is 400 For Intel and 100 MHz for AMD, the memory speed supports only DDR 266.

If the FSB of your CPU is 533 For Intel and 133/166 MHz for AMD, the memory speed supports DDR 266/333

If the FSB of your CPU is 800 MHz for Intel and 200 MHz for AMD, the memory speed supports DDR 333/400

You'll have to underclock the memory from DDR400 to DDR266.

And how many modules do you have installed and please tell me the bios settings you have set as well.

 

I currently have two modules XXXXXXX 256Mb DDR333

 

Bios settings are:

Dram clock: 333 MHz

Cas latency: 2,5T

Dram RAS Active time: 6T

Dram RAS Precharge time: 3T

Dram RAS to CAS delay: 3T

 

While CPU clock is 100MHz (1.8Ghz 100x18)

 

I'd like to replace them with a module Corsair CMX512-3200C2PRO

 

You'll have to underclock the memory from DDR400 to DDR266.

 

:eek: I didn't know that!

The two modules that I'm using now are correctly recognized as DDR333 and bios Dram clock setting is 333MHz (400MHz is also available in manual settings).

Does it mean that my bios values are not true? :(:

So those FSB/frequency rules were only for MB's that can only run memory in sync, right?

Does it mean that CMX512-3200C2PRO could work at 400Mhz on my system (with right manual settings)? Or will it work anyway as a DDR266?
