Just recieved this $99 E8200 from MC for my HTPC on Saturday. Been playing with the settings yesterday, but I think this is it.

It still is an ongoing priming stable....so far so good for more than an hour.
Yes, I've sacrafied a little HEAT for a super quiete fan instead.

Spec:
Gigabyte P5E-DS3R
4GB G.Skill PC6400 F2-6400CL4-2GBPI-B
Cooler Master Geminii S (with low speed/quiete fan)
Antec 430W TruePower Trio
and a 7500 LE from my parts bin :)

E8200 stock 2.66GHz = 4GHz = 500 FSB = 50% overclocked

Vcore Bios: 1.41250
DDR2 Overvoltage: +0.3
FSB Overvoltage: +0.3
MCH Overvoltage: +0.3
Ram Overclocked: 5-5-5-15 @ 1000MHz

Nice OC!

I too picked up a e8200 from microcenter, on special.

It's also a C0 stepping.

I'm able to get 3.8ghz stable @1.36v

It's running a bit hot though. I've seen ~74degrees full load (Orthos), and ~49 idle.

Great little chip! This thing screams!
 
I hope the one i have coming can do 4.0ghz.Ive been told it can do 3.6ghz at stock voltages plus the one i have coming is a extra spicy.My frist Extra Spicey

It should be able to do 3.6 w/ stock volts.

Mine did 3.6 with just a fsb change. Stock everything.

3.7 took a little tweaking.

3.8 a little more...
 
I swear E8200s are really E8400s in disguise. They seem to reach the same frequencies.

My brother in law's E8400 hit 4.42ghz on air. Went past 4ghz on stock voltage!

My chip is nothing like his. I think he had an E0.

Although after a bit of reading, it appears the L2 cache timings were loosened up in the E0's, compared to the C0's. These looser timings account for the increased ability to overclock, although sacrifice a bit of performance (comparatively).
 
Sadly, 500fsb was not stable with up to 1.43750 Vcore. I didn't try any higher of which may have help.

But, at a reduced 490fsb + 1.42500 Vcore I got 5hrs sFFT P95....but did not pass IBT v2.2

490fsb + 1.45000 Vcore was required to pass IBT v2.2 with maximum stress at 87C.
3.92GHz = 47% overclocked

Those are better than I thought, kind of wish I could trade my e8400 for one and get back the price difference. Best my C0 does voltage-wise is 3.825 at 1.25v, so I guess I didn't get ripped off too badly.
 
Now it's time for that best performance ratio to voltage and heat.
Too bad that I couldn't lower anymore on heat due to its lower profile HSF in my HTPC.
Testing done in Summer.

I've scaled down to 480fsb + 1.38125 Vcore bios
Trimmed 10c during IBT v2.2 at maximum level = 77c
Prime95 small FFT = 65~66c
During IBT load voltage at 1.312 solid in CPU-Z (1.344 idle)
@3.84GHz = 44% overclocked
