But you're making statements without backing them up with links or proof.

I included a source for the statement on memory voltage. As for Nehalem using the same manufacturing process, that is just in line with their Tick-Tock release time line.

So now I am completely confused:

In this bit-tech.net guide they say:

http://www.bit-tech.net/hardware/200...-core-i7-920/3

While Asus and Intel (rightly) scare everyone (read: uneducated) into thinking that 1.65V on the DRAM voltage should be the absolute limit before you reach for the fire-blanket, all that's really needed it to obey this: keep the CPU uncore voltage within 0.5V difference of the DRAM voltage and there's no problem.

where uncore = qpi/dram voltage.

But in the one you sourced, they said the .5 refers to the CPU voltage itself needing to be within the .5

Intel performance guru François Piednoel was keen to stress that the CPU voltage must be kept within a 0.5V potential difference to memory.

You raise a good point... I'll have to look into that.

I'm pretty sure it's uncore and vram.

I was already aware of that 003.

My question was more about the whole max voltage thing.

I'm not scared to give the chip some juice if it needs it, but I was just curious if you had a source or if you are just quoting the evidence that's out there (BTW I do agree with you that there was a lot of FUD spread about the 45nm chips being delicate flowers)

Are there any helpful guides on overclocking a Ci7 for a noob oc-er like me? All these guides I've been reading are like "how to clock it to 4Ghz zomg", and I really don't want to just jump right in like that haha, I wanna work my way up, y'know. What's the step-by-step?

Thanks for the link, good video. Do you know if anyone has documented in an article a step by step guide of how to approach i7 OCing? Something similar to this video but something I can also print out and have beside me.

You can try these to start:

http://www.bit-tech.net/hardware/200...-core-i7-920/1

Basically, you need to work on raising the bclk which is your basic system multiplier.

You can experiment by lowering the CPU multiplier (which goes as high as 20 on the 920) and then raising the bclk as high as you can get it (from what I've seen it can go to around 190-200)

Then you can try bumping your CPU multi back up one by one.

Unfortunately, I don't have my rig up and running yet, so I can't give you a step by step of what I would do, just theories based on what I've read.

Oooh.. nice link, zlojack..

First attempt, the easiest platform to overclock so far. It has never been so easy.
