Hello everyone, several days now im trying to Overclock my system on E8400 at 4Ghz but no luck.. I can have it stable easy at 3,6 or 3,7.. My specs :
OS: Windows 7
CPU: Intel Core 2 Duo E8400
Motherboard: GIGABYTE GA-EP35-DS3L
CPU Cooler: Thermaltake Frio
So i have read lots of threads last days.. I managed to get to 410x9 FSB , 1.32vcore ,Ram multiplier x2 on 820fsb and default settings on timings and NB-FSB volts .. only +0.3 to dram to match 2.1 of corsair recommended . My temps are sweet 51 C maxtemp on 8hour prime95
After i try 420x9 my Mobo posts but wont boot to windows.. i aslo notched NB to +0.2 and FSB to +0.2 , vcore to 1.38 and loosen timings on ram ( 5-7-7-24-68) but still nothing.. i get a blue screen when windows start to boot..
Am i missing something ? Im not realy experienced in Overclocking but seems like my ram is refusing to work at this FSB even though its rated for 1066 which means i dont push then i guess.. Any help appreciated.
Thanks in advance
