CPU : Sempron 2800+
MOtherboard : Biostar Tforce 6100
RAM : Corsair Value Select 512MB
VGA : MOtherboard build in Geforce6200 TC
Sound : Onboard ALC655
Hardisk : Maxtor 80G (IDE)
CDROM : LG 52XCDRW
PowerSupply : Cheap 480W attached with casing (no truepower)

All overclock are default voltage
I tried to increase volage to 1.5V can acheive 363*8
Voltage to 1.65V only 365*8
For 350*8 I dont have sp2004 so use 3Dmark and superpi and winavi to check stability
Its mean sempron not sensitive with voltage

I want to ask the power supply serious influnce to overclock?

2T can reach how much?

hehe dun kacau other ppl topic pls
anyway dun expect so much from corsair vs series la, i had enuf bad experience wif them

Oh ya..I hv always been wondering..
Which is older? 6600 or 6800?

Dual channel already fast speed enought, your comp have a excellent combination except the RAM, sometime no meaning to spend for a little bit performance increase.
May I to know how many second for your system running in SuperPi 1M?

There's no FSB anymore in A64 system. I'm a bit vague in my previous statement about the external clock. In yr statement :
According to the setup above, 2.4GHz with 6 x 400 is impossible to outperform 2.56GHz @ 320X8. It is because the 2.56GHz system has higher CPU clock and RAM speed than the 2.4GHz counterpart.

External clock can boost performance only if u hv a fix multiplier, let's say 6x. 6x 400 of course will be faster than 6x320, However, 6x400 wont be faster than 10x300.

the low superPI score of magiara system is due to slow RAM (185MHz only), but not the CPU. I believe if he is able to make 2.5-4-4-8 @ 233MHz, the superPI result will be a lot faster

Anyway, may i know where u bought this BIOSTAR? 

fed it with more voltage ?

higher ram fsb gives better result
