Hi all,

my pc spec:
AM2 X2 3600+, Biostar TA690G (Bios R69AM605.BST), GSkill F2-6400CL4-2GBPK

Yesterday i mange to oc my X2 3600+ brisbane to 9.5x290 = 2.75GHZ with 1.35v, orthos stable for 6 hours, passed 3dmark06, OCCT and dual superpi, HTT set to 600MHZ or 3x, RAM SPEED is below 800MHZ cause i use 533MHZ in bios...
Everything are working fine.

But today when i start my pc, it show me some weird sympton...
this msg appear in CMOS --> "warning!! your system running safe mode. please setup CPU host clock"

when i press F1 to continue, window can load but the processor speed was back to 1.9GHZ.

when i restart it and check in bios, the CPU FSB show in bios still is 290MHZ... after reboot
msg --> "warning!! your system running safe mode. please setup CPU host clock" still appear in CMOS
and when load into window, it still show 1.9GHZ and CPUZ show 200x9.5.

then i have to reset bios to default by using load optimise default;
msg --> "warning!! your system running safe mode. please setup CPU host clock" disappear from CMOS when boot; and i have to set FSB, 200, 220, 250, 270, 290 and restart for few times to get my window load at 2.75GHZ.... crazy...

i'm not sure where was wrong.... izzit coz by bios version?
help...

Here is mine:

AMD Athlon 64 X2 3600+ Brisbane @ 3002Mhz
BIOSTAR TA690G-AM2
GSKILL F2-6400CL4D-2GBPK @ 1000Mhz 5-5-5-15
COOLERMASTER GeminII

Passed OCCT, 3DMark06, and dual SuperPI 32M

Bro, the memory divider for TA690 very senitive.
always kena safe mode if playing too much memory timing in Bios and limit our overcloking.

as usual, try find out the max FSB of ur mobo, highest achievable speed for RAM, and then only max proc speed...
i had tested my RAM can do 1100Mhz 5-5-5-15 with 2.1v, had passed dual memtest 1200%, dual superPI 32M, 3DMark and OCCT.
i believe my brisbane's OC result still can improre...

want to ask u guys especially for those whoes is using Biostar TA690G mobo...
do ur mobo have psu compatible issue??
thanks
