I realize this is probably way more information then you need but what I am mainly looking at now is the Memory Frequency at 367.0 MHz. I realize its double data rate so the speed is actually at 734.0 MHz. Now the CPU is very fast like you said it's 3.30 GHz. I ran memtest 86, the ram had no errors.


I try running Prime95 but it stops and it can not complete. I am sure this means that I have an unstable system? :heink:  I might be doing something wrong, if i am please let me know.


Last questions


Overclocking is great but why does your ram have to be so slow? I actual have DDR2 Corsair Dominator PC2-8500C5 1066 MHz.


Is there a way I can overclock my CPU and still get the same speed of 1066 MHz on my ram. Again Thank you from your time and effort in helping me, really thank you

You forgot to cover the heat aspect. Have you checked your temps?

First thing, are you still running at stock voltage? If so, you can increase the core voltage safely to 1.45 volts as long as the temps stay below 70 C.

Set your RAM voltage to factory recommended levels, probably around 2.1 volts or so.

Just overclocking RAM, especially on a Core2 system, gets you little more than an increase in instability.

When you are running Prime95, what fails? If small fft's is failing , look at CPU settings. If large fft's or blend is failing look at memory settings.
