View Full Version : New Motherboard and PC100
12-09-2000, 01:31 PM
I am going to build a new system the motherboard I am looking at is ASUS A7V with a Athlon T-bird 1Ghz, the motherboard has a 200Mhz front side bus. I am planning on using my 265MB of PC100 which I already have. My question is will the RAM be a bottleneck, will the bus be a 200Mhz, or will it have to be set at 100Mhz? Will DDR SDRAM at PC200 greatly improve performance? Thanks in advance!!

To run PC 100 you'll have to set it at 100 MHz, with 256MB I don't think you'd see a signifigant bottleneck. Not sure about the DDR option, but if it were me I'd wait a year or so until it's proven, and not still in the trial stages.
Soon as I come up with all the answers...they change the questions!!

This is a common misunderstanding with the athlon bus speed...the bus is actually just 100 mhz, although some mobos allow you to run it at host clock plus 33 mhz...the 200 refers to the fact that the memory bus is accessed on the rising and falling portion of the clock cycle: twice 100 is 200...you can use what you have now, you might even be able to run it at 133 if your board has that setting...my pc100 ran at 133 although I had to change the latency from 2 to 3...
