hello guys,
this is my first post and also my first attempt to overclock my system. before that below is my system spec
,
CPU - Intel Core 2 duo E6320 (1.86Ghz) - running on Vista Ultimate
Motherboard - Gigabyte GA-945GCMX-S2 (rev 6.6) - support 1333FSB
RAM - 1Ghz Apacer DDR2 667mhz
GPU - Gigabyte Nvidia 8600GT 256MB (Overclock to 660/820Mhz)
Hardisk - 250GB Sata Samsung
Cpu Cooler - Stock Cooler
PSU - 500W Telcom power Supply
so here is the problem:-
1) i was able to push my cpu to 2.45Ghz (350 FSB - Run on orthos for 3 hour without problem) at stock Vcore (1.325v at bios but it seem diffrent on cpu-z) and increase the DIMM Voltage +0.1V. Memory:Cpu set to 1:1, but when i increase the FSB to 360, orthos test only last for 1 min before crash... i tried to increase the Vcore to 1.4-1.5 also still crash on orthos.. i even tried to increase the FSB voltage (+0.1V) and Dimm Voltage (2.2V) but still cannot stable at this fsb... i do not know what wrong and FYI my idle temp is 40-43c and max load on Orthos is about 60c.. please advise
2) secondly, it seem that this motherboard has pci-e frequency set to auto, SYC and ASYC. for the overclock above, i let it at Auto, but ive read somewhere that we have to set PCIE to 100mhz (Which is ASYC option on bios) but when i set it to ASYC, the bios will reset itself to default value (which it will back to 1.86ghz (266x7)) - i dont know whats wrong with this...
3) please help and advise me what bottle neck my system - my 3dmark06 score is just 4726-4950..
4) is this because of the motherboard fsb limitation or what- if i set fsb above 380, the bios will reset to default value...
thanks for your help...
