How bad is the vdroop depends on the motherboard, it varies. You increased the voltage so obviously the temp will increase a little.

Sorry, I didn't notice the screenshot links were all broken I'm currently doing 515x8 (14-4-4-4) at 1.4875V and I'll try post a screenshot later today Previously I needed around 1.4125V to get it running 4Ghz stable (if I remember correctly).

I'm using the first few batches of E8200 so it doesn't overclock that superbly compared to the new E0's you guys are having Since it's an old junk then I might as well stress it more. If it's broken, I'll have a new excuse to get the E8600

I'm on water cooling and Small FFT at 1.4785V can go up to 64C-65C full load.

My friend's E8400 idles at around 55C-60C and very likely it's a problem with the thermal sensor. I'm not sure if Intel fixed it on newer batches? I haven't been reading up news for some time

If that's the case then it's a problem with the digital thermal sensor on the chip. This has been a known problem for the 45nm dual cores for a while.

Of course it does and that's the whole purpose of it. As to how much it'll save, that would probably be something interesting to know.

No ideas where did 100C came from though

My C0 E8200 needs 1.4625V for 4.06Ghz (508x8) so the E0 is still better in some sense

You're saying multiplier plays a role in the voltage? 9x400 and 8x450 needs different Vcore?

I've tried before but it requires more Vcore, all the way up to 1.5V so I stopped. It doesn't even hit 4.2Ghz yet at that time.

I don't think so. If your chip is stable with 1.3V @ 4Ghz then it'll always work at that same Vcore at such speed irregardless of whatever FSB x multiplier combination. However as your FSB increases, there are other voltages to worry about, not the Vcore (assuming both setup is of the same clock speed). Front Side Bus is a bus connecting the CPU to NB/Memory controller so why does increase of FSB had to do with CPU Vcore?

At least all my life of overclocking since Intel 486DX4, I've never encountered a situation whereby more Vcore is needed for a different multiplier/FSB combination of the same clock speed.
