I recently put together a new computer with a Gigabyte motherboard (400FSB, VIA KT600 chipset, DDR400) and put in 512MB of PC3200 Kingston Ram. I read that using this setup its capable of up to 3.2GB/s but normally around the high 2’s. When I ran a Memory Bandwidth Benchmark using SiSoftware Sandra I got just over 2.1GB/s. When I first ran up the computer I also has a 256MB chip of PC2100 Ram, and found out that it would slow my 3200 ram down this the slower 2100 speed ram. I have since removed it to see if I could get the approx figures that Sandra said I should get with the KT600 chipset and DDR400 ram. But no luck. Does anyone know if that’s normal for a 400FSB with DDR400 and AMD Athlon XP 2600+ Barton. Any another thing, what is the main advantage of really fast RAM, does it help the CPU?
