Memory problem

docphi · 08-January-04, 08:56 PM

Guys, I have a Micronics c400 motherboard. I can upgrade the memory in two of the three memory slots and the board works fine. If I fill the third RAM slot, the board slows down to a crawl. They are three identical RAMs I bought at the same time. Any help would be appreciated. Thanks!

Probably because the Intel 440BX chipset on that board can't handle that much ram (768MB Max) and it sets the cas to 3-4-4-8 with three dimms. It's not like more ram is going to help a system that old very much anyway.

Thanks for the reply! I should have specified that they are 256MB chips. So it's maxed at 768MB as per board specs.

What exactly do you mean by "cas"?

Thanks again!

It means Column Address Strobe...

Basicaly it means how many clock cycles it takes to process Data in the memory.

CAS comes in 3 flavors:

CAS 2= clock cycles= fastest
CAS 2.5= 2.5clock cycles=medium
CAS 3= 3 clock cycles=slowest

Only top of the line Memory like Mushkin or Corsair use CAS2, that is why it costs do much money

HERE is a link with a Tutorial w/Audio...It explains ALL the details of memory...better grab a Beer and enjoy!

Thanks guys! Looks like I need to upgrade to a newer system. Not that I'm complaining!
