Hello, everyone. This is my first time posting here, but I have read the overclocking stickies, and I have read tutorials from various other overclocking websites/forums. To sum up my problem, I can get 3.1 GHz completely stable with good temperatures running Orthos for several hours, but when I try and bump up to 3.2Ghz (my original OC goal), the system freezes when I open a program from Windows.
About my PC:
Abit Fatal1ty SLI edition Mobo
Patriot PC6400 DDR2 800 4GB Ram
Intel Core2Duo 6750 Processor (currently running at 3.1GHz OC, default 2.66, Voltage at default, 1.35VCore)
EVGA 8800GTX, not OC (waiting on my HR-03 Plus VGA Cooler)
2 SATA Maxtor 250GB Hard drives
As I said, when I try and run at 3.2 GHz, my comp freezes when I open a program. At first, I thought I needed to give the processor more VCore, so I bumped it up to 1.375 V, but that is not the case.
What could be a possible problem with trying for the 3.2GHz? Is it my RAM? Currently, I am not overclocking my RAM or deviding it. My Mobo will not let me use my own ratios... for some reason it is locked, and I do not understand why.
Do I need to overclock my RAM? Or am I stuck at 3.1GHz? I am fine with 3.1GHz, but I'd liked to go a little bit further with the good temps I am getting.
It can go much higher.
First of all, u need to check how hot your computer is running @ to see where the bottleneck is. 2x degree to 40 degree is acceptable for the CPU. 4x degree acceptable for motherboard temp.
3.6GHz is no problem for that CPU.
RAM, depends your setting but I'm running mine @ 2.2V.
Ratio @ 8 which is default
Run CPU @ 444 and DDR800 will be 1066 and add RAM V so that it becomes stable. It'll depend on how hot your RAM is. It is important. Get a corsair fan for RAM. 4G ram may have bad ventilation hence high temperature and bad OC.
Display card is no problem.
If still no sucessful, bring down the ratio so that RAM runs at lower speed. Remember to set you latency.
I do not know what case you are using now, but with the case I recommended, you should be fine with 4G ram or else I don't find air ventilation good with Mid tower cases. I still think 2G ram is better as it won't pack the heat. Remember, heat is your largest enemy when oc
