Hello there :)
I'm totally lame with HW, but decided to write here. I'm simply not sure if I get full preformance of my memory. So maybe sb would help me.
Here's the story:
I have Gigabyte K8NXP-SLi MB, Athlon64 3000+, and 1GB of RAM in Dual Channel mode: 2x Kingston HyperX 400MHz (KHX3200AK2) with 2-3-2-6 timings, all running on WinXP 64-bit edition. I decided to buy the memory as it achieved some nice points in PCMark test:

the configuration of the tested machine above is:
Gigabyte GA-K8NXP-9
Athlon 64 3500+ (Socket 939)
512MB Kingston HyperX DDR400 CL2 (KHX3200AK2/1G)
Windows XP SP2
nVidia ForceWare 66.93
PCMark 2004 (build 120)
Impressed with the points I thought it would be very nice to have such an effecient memory and then just buy X2 processor when prices drops.
But when i ran PCMark on my O/S (also tried win2k earlier with similar effects) I got around around 4100 Pts. Confused with it I decided to get into BIOS settings... I found that it has M.I.B 2 option which succesfully boosts the performance without ingering into settings, after applying i got 212 FSB instead of 200 and Memory Pts jumped to 4413... I decided to press on :). I found that my MB actually reads the RAM timings and for 200Mhz sets it like this: 2.5-3-3-8, so I decided to change them to: 2-3-2-6 which gave me just +30 pts... not much, i reached 4444 pts. but the os doesn't seem to be stable... blue screens etc. i decided to leave the default settings: 2.5-3-3-8.
I ended up with 4413 Pts which is quite below 5200 pts I read on the benchmark.pl site... Not sure why such a big difference... Could you help me to find out?
