Well, the gf recently got me a brand new shiny graphics card, and I realized my old AMD Athlon 64 just wasn't cutting it. So, I jumped on the E5200 + MSI G31M3-L V2 deal from Fry's for $79.99 a week ago.
I certainly must say, there are a lot more to tweak now, and after spending a good amount of the long weekend going over this forum and many other sources, I have done the following:
1) BSEL mod -> 1.35V
2) Upgraded to Arctic Cooling Freezer 7 Pro
3) Did the unthinkable... went to 4.0GHz rock solid stable with 1.35V!
Now, all other things aside, my greatest question right now is:
How am I able to do this with a CPU whose original VID was 1.250V, which is rather high? I know from what I've read, the "sought after" e5200's are the ones with the 1.1xxV VID's as they would ensure higher FSB at acceptable voltages. But, here is my story...
When I first fired up my e5200/VID 1.250V, I tried 3.0GHz just for fun as the crappy MSI G31M3-L V2 had no CPU voltage adjustment options. The thing booted, and I played Fallout3 for almost 4 hours. Next day, I thought, what the hell... I booted up to 3.5GHz and played a few more hours of Fallout3. At that point, I realized something was amiss because given the high VID of 1.250, I wasn't expecting much out of my e5200.
Just to make sure I wasn't going out of my mind, I tried 4.0 GHz (320x12.5) at stock VID of 1.250. Damn system didn't boot then. Good, not dreaming.
So, after reading about the BSEL voltage mod, I of course had to try just one more time with 1.350V. Unbelievably, not only did it boot up at 4.0GHz, but it went right into WinXP and I ran 3DMark2006 3 times. Then, I played Fallout3 for about 5 hours.
Needless to say, I'm shocked... stumped really. I wasn't even expecting my little e5200 with 1.250V VID to hit 3.5GHz, much less 4.0GHz... and only at 1.350V! Is this a fluke, or did I just simply get lucky??
As always, many thanks in advance and look forward to your feedback.
