E7200 v at 400fsb question

I just ordered a new build around a e7200 and a P35-DS3L and will be putting it together this weekend.
I'm wondering if anyone has done this with the e7200 and was wondering if they had to increase the voltage to get to 400x9.5 ~3.8ghz.

I plan on comparing this system head to head with an identical e8400 system @ 400fsb


Thanks.

hope you mean 3.8GHz :)

anyway, that sounds feasible, just remember to cool the thing off properly...

Yikes, these guys at legit had to throw 1.5 volts at it. I probably wont keep the voltages anywhere near that high. Ideally I'd like to keep it under 1.4.

Using 800mhz ddr2, I wanted to go 1:1 but if I can't hit 400fsb safely is there a preferred ratio to run the ram?

I'm using the HDT1283 cooler with this chip. Had good luck with it on my e8400.

Huh?

Anyhow... Use 1:1 and drop mulit down to 9x instead of 9.5x, that way you stay under 1.4v and you can reap the benefits of a linked FSB to ram ratio of 1:1 and be sittin at 800mhz.

My e7200 is at 3.8Ghz, 400fsb and the voltage is 1.33v'ish. My temps have not exceeded 55c. I ran 3dmark and a half hour of COD4 at high. Neither time did it exceed 55c.

FYI for your head to head
E8400 @ 3.6ghz
4GB 6400 @ 800mhz
400fsb 1/1
1.216 vcore

Very nice! I sit at 1.225 bios, 1.20 CPUID at 400mhz or 3.6ghz. However, for 4.05ghz or 450mhz I need 1.39v. I like the 1:1 @ 400mhz for the memory though. Very solid overclocker!

Beechmunky: If you compare a E8400 to E7200 at 400mhz the E7200 will be 3.8ghz while the E8400 is 3.6ghz. I would still bet that with the added cache of the E8400 that it will be slightly if not much more faster than the E7200 @ 400mhz. Your talking 3mb compared to 6mb.

So... If you've seen how those E2xxx's perform overclocked you'll know that cache doesn't play a big factor in general performance.

agreed!
