G'day all, I can deal with the nuts and bolts of a computer,but my knowledge of some of the theory is sadly lacking.So perhaps some kind soul out there can clue me up on the following.I am currently running an AMD 2200+ CPU with 266 FSB.I also have 256 DDR 2100 memory rated at 266. I want to upgrade my CPU to something like an AMD 2600+ which has 333 FSB.Does that mean I have to change my memory as well.what would be the effects of running 333 FSB with 266 memory. Any guidance would be much appreciated.
You wouldn't get the full speed from your processor running the 266 DDR(PC 2100) memory. It was so much easier when there was only SDRAM PC100 and PC133. Now they have changed the naming convention for DDR RAM, using bandwidth instead of speed as the numbers. Here's how I understand it. There are four speeds of memory PC1600, PC2100, PC2700 and now PC3200.
PC1600 if your CPU is 200 FSB.
PC2100 if your CPU is 266 FSB.
PC2700 if your CPU is 333 FSB.
PC3200 if your CPU is 400 FSB.
To get your CPU to run at those speeds, your motherboard has to support that FSB.
Someone correct me if I'm wrong. And don't ask me about Pentium chips, I'm confused enough. :-(
Thank you for your responses.Jester2K II,my Mobo is an MSI KT4V and will support CPU's up to 2800 xp+,and 333 FSB.I suppose I ought to go up to DDR2700,but it seems expensive to do this.I was hoping I could get away with a faster CPU and current Ram settings,Oh well!! Regards Tony
