Hello , somebody who can help me ? Sometimes it no display and got sound 'beep' like no ram plug in . But i off and turn on again it can run My Pc Spec is like below :
Abit KN9 Ultra Motherboard
Athlon64 3500+ processor (AM2 Socket)
Kingston 1GB DDRII 667MHZ Ram x2 (Run Dual Channel )
MSI 8600GT OC Edition
Cooler Master extreme power 430w power supply
Asus DVD-RW Sata Drive
Seagate 160gb sata HDD
Seagate 80gb ide HDD

My BIOS setting like that :
My bios setting is like that
FSB = 252MHZ
Multiplier = x11
pcie clock =100MHZ
cpu core voltage =1.550V
Ram voltage = 1.90v
HT speed = 3x
cpu cool and quiet control = disabled

DRAM setting is 667MHZ
cas latency =5 clocks
TRCD=5 clocks
Trp =5 clocks
Tras=15 clocks
Trc = 19 clocks
Trfc0 for dimm1= 127.5 ns
Trfc1 for dimm2=127.5 ns
Trfc2 for dimm3=127.5 ns
Trfc3 for dimm4=127.5 ns
command rate = 1T

After that i got one question , i use this bios setting previously can overclock to 256MHz X11 (2816MHZ ) , but now cannot reach again if my ram plug dual channel , but can boot if i use 1 ram only !
This is my question , Thank for all the people can help me !

Thank for suggestion from dblooi , i use stock cooler only , Normal use like download movie and watch movie the cpu temp reach between 50c and 57c !!

Maybe i will change other powerful cooler later , but my big problem is i lower down the memory divider to 533 or 400 , it directly no display and not any beep sound come out ! If change command rate or trfc also like that !!!
Got any suggestion again thanks......

Hello , somebody can guide how to oc more higher for my spec :

Below is my pc specification:
Abit KN9 Ultra Motherboard
Athlon64 3500+ processor (AM2 Socket)
Kingston 1GB DDRII 667MHZ Ram x2 (Run Dual Channel )
MSI 8600GT OC Edition
Cooler Master extreme power 430w power supply
Asus DVD-RW Sata Drive
Seagate 160gb sata HDD
Seagate 80gb ide HDD
AMD Stock Cooler


Now my bios setting is like that :
FSB = 252MHZ (2772MHZ)
Multiplier = x11
pcie clock =100MHZ
cpu core voltage =1.575V
Ram voltage = 1.95v
HT speed = 4x
cpu cool and quiet control = disabled

DRAM setting is 667MHZ
cas latency =5 clocks
TRCD=5 clocks
Trp =5 clocks
Tras=15 clocks
Trc = 21 clocks
Trfc0 for dimm1= 195 ns
Trfc1 for dimm2= 195 ns
Trfc2 for dimm3= 195 ns
Trfc3 for dimm4= 195 ns
command rate = 1T

Previously , i can overclock to FSB=256MHZ (2816MHZ) before 1 week , But now directly no display and no beep sound again . So i force to downclock to 252MHZ .
Can expert recommend some ram timing , voltage setting to push back my speed back to 2816MHZ . Thanks

Thank the advice given by alive88 , but i thing is my cheaper ram problem , if i use 2.0v vdimm , my pc start to lagging , maybe my ram not having the cooler ! I now using the program download from abit website to determine my pc temp , it will show dangerous voltage given for ram if i set vdimm to 2.0v . The vdimm limit given is 1.98v , if i set 2.0v must exceed 1.98v when running the pc , so it will start lagging when vdimm exceed 1.98v . How can i settle this problem , can give me some suggestion . Thank !!!

After that i got one question , now my cpu clock is 2816MHZ , but when i play game (Unreal Tournament ), cpu usage maintain 100% and cpu temp between 60c ~65c . I play not reach half and hour will BSOD (Begining of dump memory ) , i dont know is ram voltage problem or other reason caused BSOD ....
Every sifu can give me some suggestion ! Thanks !

I dont know what software to use to testing it ?
But i have one software named ( Hot CPU Tester ) , please give advice , thanks !!!!
