Whats better for gaming e7200 or e5200

Hello, I'm trying to figure something out. My gaming pc has p5q pro turbo mobo and e7200 cpu. I can only oc the cpu to 3.6 ghz. My 2nd pc has cheap Foxconn mobo and e5200. With the lesser mobo I am able to oc the 5200 to 3.8 ghz without breaking a sweat. I'm sure if I used the 5200 with the p5q mobo I could oc it even higher. I think it's because the e5200 has 12.5X mult and e7200 only has 6.5X. But the e7200 has greater fsb and cache. Do you think it would be worth it to switch cpu's? I'm sure I can get it to 4ghz easy! But is clock speed more important than cache and fsb. BTW I'm using Crucial Ballistix 800mhz ram.

FYI, the FSB on the chips are only the default value. If I had a 266 MHZ fsb on 1 and 333mhz on the other, but I overclocked both to 400 Mhz FSB, they both have the same bus speed. The only reason the bus speed is on there is so you know what's default.

You are probably right, you might be able to overclock the e7200 better in the other mobo. It's usually much easier to overclock a chip with a high multiplier because you only need to raise the FSB a little.

Also the Asus board might have more settings that you could tweak to get it to OC faster. Are you just raising the FSB to overclock? What about voltages and RAM speeds?

Guess you will have to try ? :)

What volts are you feeding the 7200, on that asus board you should easily get 3.8Ghz.

What memory as well.

On Asus Mobo, 400fsb with e7200 default multiplier you get 3.8Ghz.

Set memory to 800MHZ or 1066Mhz depending on your memory!

Set V to 1.365, Max Intel Safe Limit!

My second system is ASUS p5q with E7200 @ 3.8Ghz exactly like this!

For the e7200 I had vcore at 1.41. At 1.36 it wouldn't pass prime95 at 3.6ghz. The Ram I loosened the timings to 6-6-6-18 and set volt to 2.0. Ran 1:1 ratio with fsb. I also raised nb, sb volts.

The e5200 was able to hit 3.8 with the Foxconn mobo, which only has adjustment for vcore. I raised it to 1.36. It also is using lesser ram. Also Crucial. I think I loosened the timings a bit. That's why I think I should use the e5200 with the ASUS mobo. I'm quite sure I can get a stable 4.0 out of that chip!

I can't have my fsb at 400 and mult at 9.5 Prime stable. How did you get yours to 3.8?
