Getting Started, The Hardware
Continually-falling DDR3 prices are allowing the memory technology to displace DDR2 in mainstream-performance builds. And with the future of DDR2 desktop memory drawing short, we selected two DDR3 motherboards from MSI to support our chosen AMD and Intel processors.
Picked for its best-in-class HT clock speed capability, MSI’s 790FX-GD70 should provide optimal results for our Socket AM3 overclocking tests. Choosing the standout motherboard from previous reviews allows us to set a high goal for owners of less-expensive motherboards to attempt using the same processor models.
Our budget limit for dual-core and quad-core processors was $125 and $250, respectively. AMD sent its Phenom II X4 955 Black Edition ($245 retail value) and Phenom II X2 550 Black Edition ($100 retail value) for today’s overclocking guide. Black Edition processors are special from other Athlons and Phenoms in their ability to manipulate the clock multiplier upward, allowing high overclocks to be achieved at or near the processor’s original 200 MHz HyperTransport reference clock.
We requested MSI’s top P45-chipset motherboard to maintain fairness between processor brands, and the firm responded with its P45 Diamond.
A higher average price gets buyers fewer graphics card slots. MSI makes up for the value loss with added features, such as a PCIe audio card and a chipset water block with copper line adapter kit.
Nobody said we had to spend our entire budget on processors. Focusing on the value segment brought us to the $70 dual-core Pentium E5200 for its high CPU to front side bus multiplier and good overclocking reputation, and the $160 Core 2 Quad Q8200 for its reasonable cost.
Intel doesn’t produce a 45 nm desktop quad-core with anything less than FSB-1333, and each model up gets us a slightly higher (0.5x) CPU multiplier at a noticeably higher price. Like AMD’s Black Edition, Intel also offers Extreme Edition processors with CPU multipliers that can be manipulated upwards, but Intel charges so much more for this feature that we couldn’t possibly consider any of these for use in a value-oriented overclocking guide.

Using top end motherboards isn't really budget overclocking, a cheap p43 board is sufficient for e5200 overclocking, additionally a q9400 is only 25% more than a q8200 and overclocks to 3.5Ghz with ease
..or allows, considering different models often come off the same wafer xD
Still, I doubt the AMD-basher's will let that one rest..
I like it. I like to see how far we can push this technology as well as how to keep the idle TDP as low as possible. I think the phenom II 955 suits me the best. AMD overdrive allows you to set both preformance settings as well as the idle settings. Something were i7 failt for me.
I would like to keep cool and quiet on at all times because i dont would want a high power bill and because my computer is on for a few days in a row. So my challenge would be how can i keep the voltage and clocks very low at idle but maintain a resonable desktop preformance. However for gaming i can use some extra headroom. i like to fine tune it well.
Why the hell did you choose an 8200? That makes no sense at all, its poor overclocking performance is widely documented.
Better would be to choose something else, then have a side note saying 'do not buy this part to OC'.
if you want a cheap stable intel overclockable intel quad core look for a Q6600 or if you really want a challenge look for a Q6700, both are very good OCers but are EOLed
Strange to think its Intel that got an unfair bashing this time around. Using top-end mobos in a budget OC session is a major no-no. Using a Q8200 instead of something closer to the X4-955BE's price tag, like the Q9300, is just plain stupid.
To be honest, switching to budget mobos wouldn't have affected the outcome that much; from what reviews I've heard the MSI 770-C45 is a perfectly decent AM3 budget OC board going for a pittance and there are a few MSI and Gigabyte P35/P43 mobos in the same price range on the Intel side of things.
I need to get out of my closet and start reading these forums way more.
Thanks for a very interesting thread
(Even if criticed by some)
e5200 oc at fsb 1066 (no voltage increasing)
What would be the lifespan of the processor.
