E5200 overclocked to 4GHz

Wouldn't it make more sense for these to replace the 4x00 series rather than the 2x00? The 4x00 series already have 2mb of cache and a 800mhz fsb
 
Actually the E4x00 series is currently being phased out by the E7x00 series.

In regards to dual cores, the E5x00 line will complete the switch to 45nm for the entire Core 2 lineup.

E2x00 -> E5x00 (sub $100)
E4x00 -> E7x00 ($100 - $150)
E6x00 -> E8x00 ($150 - $300)
 
Talk about killer price/performance ratio. It has a 12.5 multiplier so if you jump it to the normal 333MHz FSB that most Wolfies have thats 4.162GHz.

If OCed to 4GHz thats $23.25/GHz which compared to a E8400 which would be 42.50/GHz. Near double and yet for half the price.

Looks like we found the next low end enthusiast chip.
 


Well here is a screenshot with a CPU-Z validation. I am trying to make out the voltage and it looks like 1.368v but its a bit grainy:

I just got my e5200 to 4.16ghz, was my cheap upgrade from my overclocked e2160. I didn't even change the settings and it is running smooth and cool. It has yet to go over 47C during burnin and its been running Prime 95 for 3 hours. I am pretty tempted to go higher.
 
I have the Gigabyte GA31M-ES2L board and e5200 processor. I have an aftermarket zalman cooler in place. I'm not interested in taking the processor to it's limits but just wanted an easy clock speed increase. I upped the FSB to 300 mhz with the default 12.5 multiplier (now 3.75 mhz) and manually dropped the RAM freq so that the RAM stayed at 800 mhz (2.66). I have yet to stress it with Prime95 but is running stable and cool. Core temp in the BIOS went from 25 C to 34 C. We'll have to see what an overnight burn-in yields.
 
but, your motherboard has 1333MHz fsb... can't you just set it to 333MHz, and you'll get 4.162GHz without changing ram freq or voltages, like zod000 did?
