system underperforming

[flashmanandy]

Hi

my home built system appears to be underperforming in benchmarks and can feel a little sluggish at times
i was hoping that people could throw out some ideas for better performance


AMD ATHLON 6400 X2 black edition 3.2GHZ -Bus 200MHZ X16 -out of the box no OC- running at max 48degrees
ABIT AN52 V2 -520 chipset
4X1GB ocz 5-5-5-15 T2 PC2-6400 @2.1V dual channel
75GB WDraptor sata with 8Gb pagefile
2X500GB WD sata
1X250GB WD sata
8800gt 512MB
550W hIPER modular power supply
vista Home Premium 32bit-it sucks but was free-
system is 38degrees

My AN52 gave me hell from the day it arrived- it wouldnt boot 4x1gb until i changed the voltage to 2.1 and just doesnt want me to play with settings, it feels like a weak link. i also didnt have an 8pin atx and had to use a 4-8pin converter would this reduce my power to board?

The vista sp1 beta made a huge difference but it im still running slow

Sisoft Sandra has my processor comparing to a 6000 not a 6400 and 3dmark has my pc running 2000points below comparable systems

imagine i am an idiot and throw out all and every idea

thanks

Did you try it with just 2 RAM sticks?

thanks for reply
yes i tried with two ram sticks got 10775 3dmark score almost identical to 4sticks
kinda makes me laugh at having 4GB

Where is it slow? What are your separate 3dmark scores?
I get about 12,192 w/ everything overclocked.

What nvdia gpu driver are you using? did you install all the m/b drivers?

ok score 3dmark score 10741
sm2 5060
sm3 5045
cpu 2325

driver 7.15.11.6902 10-25-2007

all motherboard drivers are installed correctly and updated

when im using the system the CPU seems to be sluggish, things are slow and take longer mainly in windows. In games i dont notice it so much but every now and again theres a pause, just for a second then it resumes as normal.

sisoft sandra says my cpu is 15% below performance, C: reads at 58mb/s at 7m/s
