I don't know if any of you remember, but a while ago I was bitching about my how my Pentium Dual Core E2200 (basically a crippled Core 2 Duo with 1MB of L2) would not overclock past 2.7GHz from its stock 2.2...well, it turns out it wasn't an issue of insufficient voltage after all. At stock settings, the front side bus is 200MHz, quad-pumped to a rated FSB of 800MHz. Now, the motherboard I have, with the 945G chipset, is fully capable of using 1066MHz rated FSB.

So, I did some more research around the internet and learned that my E2200 is basically the same as a C2D E7500, just with an 800MHz rated FSB instead of the E7500's 1066MHz. I also read some stories of people who had issues setting clocks within a certain window of frequencies, but that worked above or below this window.

This encouraged me somewhat, so I thought I would try again. The last time I successfully overclocked this thing, I hit a wall at FSB 245MHz, which lead to a rated FSB of 980MHz and processor frequency of 2.7GHz. Any higher than this and the system wouldn't POST.

So after a minute of calculation, I figured that to get to a rated FSB of 1066, I would need an FSB setting of 266.5MHz. My BIOS only adjusts to the nearest megahertz, though, so I went with 266.

To my surprise (albeit a good surprise), the system POSTed just fine and here I am in Vista. The E2200 is running between 35 and 40 Celsius while I'm just typing here. After about ten minutes of running WPrime's 1024M test, it got up to 65C, which I think isn't bad for an overclock like that, although I didn't adjust the voltages at all.

After 266MHz worked successfully, I decided to see just how far I actually can push it. I'm currently running at 273MHz x 11 = just over 3GHz.

Long story short, my E2200 is now running at 3.00GHz, from the stock 2.2GHz, with no change in voltage or multiplier. :D

Here's my CPU-Z validation:

Great job! Can you tell any noticeable difference in applications & games with the higher clock?

Awesome, nice work Zam :), now if you got a waterblock for that CPU, then you could probably overclock even higher with a little increase in voltage ;)

Count_Chocu1a;4920934Great job! Can you tell any noticeable difference in applications & games with the higher clock?[/QUOTE] I haven't really done much with it yet. Vista seemed to boot noticeably faster, although I didn't time it, so it could easily be a placebo effect. The only thing I've really done so far is Team Fortress 2. Frame rates seem conspicuously smoother in places I would normally lag, like underwater with several other players.

What else would be a good way to judge? [QUOTE=computernerd;4920935]Awesome, nice work Zam :), now if you got a waterblock for that CPU, then you could probably overclock even higher with a little increase in voltage ;)

Temperature actually doesn't seem to be an issue so far, It's idling below 40C for the most part, and hasn't gone past 70C after 20 minutes of TF2.

Unfortunately, I can't increase the voltage on this ECS motherboard. I still haven't finished testing to find the absolute maximum stable FSB yet...the 945G chipset is rated to take 1066MHz FSB CPU's, but I'm already considerably past that...at 3.0GHz, the rated FSB is a bit over 1092MHz.

Also, lol@RAM freq/timings. Check the validation link or my sig. =p

Damn, those Pentium dual cores must be beasts, cause my Pentium 4 would cause a restart whenever the temperature got past 61oC.

Not bad. Sounds about right for that chip. If you had a better motherboard 3.2-3.4 would be no problem but good job none the less for having such a terrible motherboard.

And 70*C for playing TF2? Uh oh. I would be concerned about temps being that high. If you're on the stock heatsink you might want to replace it sometime soon.

If it doesn't go above 70 after 20 minutes of CoreDamage or Prime95, then you have something to talk about.

Zip encoding/decoding, audio encoding, iterative formulas (e.g. Monte Carlo or Mandelbrot), usual CPU-intensive stuff.

It hit 72C after 15 minutes of the 1024M test of WPrime, using both threads.

This processor is rated to run safely up to 105C. Obviously I don't want it nearly that high, but I don't think the low 70s are anything to worry about, especially considering this is the stock heatsink/fan with factory paste. Maybe later I'll clean that off and apply some AS5, if there's enough left in my syringe.

Under normal circumstances, I would consider undervolting to generate a bit less heat, but that probably wouldn't work so well, considering how far I'm stretching the stock voltage to begin with. =p

Well, I'm saying if you got a waterblock you could load at about 40oC instead of 70oC :deal: Or if water-cooling isn't in the budget, you might consider getting a TRUE :)

Note: I'm retarded. I must have been looking at the GPU sensor or something, because the WPrime 1024M test maxed the CPU out at 58C. Unfortunately, it experienced a Blue Screen of Death in the middle of the test, and again during TF2 on the next boot. I'm leaving the FSB at 266/1066 for now, so I get 2.93GHz overall, where it seems to be pretty stable.
