so is 10% a safe bet for E2200?

ah...ok, back to aigomorla's explanation, when i raised BIOS voltage from 1.3V to 1.312V, 2 increments of 0.006V which is my MoBo(Gigabyte GA-73VM-S2)'s predefined smallest unit, in both SpeedFan 4.33 and CPU-Z 1.43, the Vcore reading is still 1.2xxxV well below 1.3V, i know there is this vdroop thing, but i'm Prime95'ing, does that mean the increase in BIOS voltage didn't kick in?

don't think it's the auto update, so when increasing BIOS voltage i can up a little more than 1.4V, because vdroop would make the actual Vcore below 1.4V?

yes... when you put load on the cpu, the vdroop will bring the voltage down a few notches.
Make sure you keep an eye on those loaded temps tho. Dont pass 70C. Reason why we say 70C is because on each chip there is a solder holding the die and IHS together.
That solder melts at around 73-75C. And its not very smart to melt then solidify and then melt again then solidify and melt again.... you get the idea?

No offense, but I think that's a load of bunk.
I have my E2140s running 85C 24/7, and they're not melting or misbehaving.
Do you actually know of any confirmed reports of CPUs dying, that showed that the solder on the heatspreader melted?
Edit: My friend has a B3 X3210 chip, that runs hot. Before he got his current cooler, he was running at 100C core temps at load. (It was thermal throttling, and failing to keep things cool. CoreTemp started reading negative numbers, then question marks!)
I don't think his chip melted, it certainly didn't fail, and hasn't seemed to have been harmed in any way.
Not to mention, the BIOS temp shutdown options that I've seen on my DS3R - the lowest temp you can select is 70C (Tcase temp). There is also 75, 80, and 85C. If there is a risk of melting the CPU at just over 72-73C, then why do they offer such high shutdown temps?
Intel's specs for my M0-step chip list max Tcase value at 73C or so. Do you think that they would spec all the way up to the solder's melting point? Or do you think that they would leave a safe engineering margin?

The IHS is attached to the core tops with an Indium based solder allow with a melting point of approximately 100° Centigrade. Even if coretemp shows temperatures this high the solder isn't going to melt.
