OC for my E8400

So im getting to the point where i dotn know whether or not its worth it to keep ocing.

I have my E8400 Oced to 3.8GHz on my eVGA 780i

Specs:
VCC: 1.326 idle, 1.304 load
FSB: 423
VTT: 1.3
SPP: 1.450
Ram: 507.7
Temps: 37/38 Idle ~52/51 load

Now i dont know if it is worth it to run my E8400 with those volts? Are they too high? The Vdroop is killin me. What should i consider my voltage my load or idle? My temps are out of control, they really havent gone up at all with my OC. Im just wondering if my OC seems to have required too much juice. From 3.6-3.8 i need 2x the juice than 3.0-3.6.

Can i get everyones opinion?

Thanks 🙂
 
So after running prime for 12 hours one of my cores failed, however the other core ran for 19 hours. Now im in a predictiment... should i raise the VCore some more to 1.336 or should i jsut downclock? I really want to run stable at 3.8Ghz but my bum core 0 is preventing that.

Also what does it mean if one core is about 1-2 tests behind in iterations? My core 0 always seems to be 1-2 behind
 
Its only my opinion but you have some room with that voltage. Just keep looking at the load temps..................

It doesn't matter, that's pretty common.
 
I think you're pretty safe under 1.4v on that chip. I'm running 3.8GHz @ 1.36v right now and I've noticed no problems at all.
 
Take your time in OC'ing that chip. A lot of people make the mistake of pushing their FSB too fast.

For me:

Default 3.0 GHz = 1.056v (333x9)
4.0 GHz = 1.256v (500*8)
4.2 GHz = 1.276v (465*9)

That's crazy. I can (maybe) hit 4.2GHz, but not using anywhere near those voltages. I had to go 1.4v+ just to hit 4.0Ghz.
