Memory 'timing' query

  CurlyWhirly 22:46 17 Aug 2005

A friend in work has just bought a second hand PC and she is running Windows XP.
She has 224 mb RAM in an ASUS CUSL2-M motherboard click here

According to the specs in the link above the bus architecture can run at 3 different speeds, namely, 66/100/133 MHz Front Side Bus.

According to Everest:

Memory bank 1: 128 mb of 133 mhz SDRAM
Memory bank 2: 32 mb of 66 mhz SDRAM
Memory bank 3: 64 mb of 100 mhz SDRAM

Would I be right in thinking that her memory only runs at the speed of the slowest RAM module i.e. 66 mhz?

If so should I advise her to ditch the RAM in banks 2 and 3 and buy another RAM module of 128 mb rated at 133 mhz?

I have *never* heard of a motherboard having 3 different sizes AND speeds!

Thanks VoG™.
Yes I forgot to mention that she has onboard graphics!

Yes you are right the processor is only 850 mhz but she would like to increase the RAM size but perhaps not now when I tell her that SDRAM isn't cheap!
I thought that as it's old architecture that the price would drop like what happens with other PC technology like graphics cards?

Thanks for the link gudgulf.
I will ask her which memory size she wishes to buy ;0)

Thanks for the advice - I will bear that in mind.
