Memory Ratios... I ain't worked this out yet Tags: CPUs Memory RDRAM Overclocking Last response: July 14, 2002 2:11 PM in Overclocking Share Stiffler July 14, 2002 10:36:36 AM Ok I was wondering how Memory ratios work ? I reecently overclocked a PC for a friend without knowning what the mem ratio's did... so I just ignored it Its running PC800 RDRAM at 115FSB But what does this mean the memory is running at and how do you work it out ? Tim I can call you Betty, and Betty when you call me... You can call me Al More about : memory ratios worked camieabz July 14, 2002 2:11:13 PM Right. Can't remember all the lingo, but it's kinda like this... FSB = 100. P4 = quad bandwidth = 400 Dual channel = 800 Least I think so. Therefore: 133FSB = 533FSB = 1066 memory. On DDR systems: 100FSB = 200MHz DDR = PC1600 133 = 266 = PC2100 150 = 300 = PC2400 166 = 333 = PC2700 The PC number equals MB/s tranfer rate. I just know I'm going to get flak for not explaining it correctly, but hopefully you'll get the jist. <b><font color=blue>~ What do you mean "It isn't working!"...Now where's my sonic screwdriver? ~ </font color=blue></b> Can't find your answer ?
