Wow, nice thinking!
Are there any downfals to this?

The Bloodrage BIOS has an option to select turbo "always on" to keep the multi at 21.

100% power draw all the time When you arent using your computer wont go into power saving mode. IDK I seem to be the only one on this forum that actually likes the power saving features that intel has but that is just me. Since I am running 3.8ghz 24/7 now its really good to know that my computer will downclock to 2.4ghz when i am away.

I got to 4ghz without changing in voltages.

Not sure what your heatsink/fan is, but i completely recommend the CM V8 if you want a good one. Has a completely flat/smooth base (unlike most the heatsinks i've seen), and does great with stock fan, but i suggest removing it with a higher rated fan. (I haven't swapped fans yet, but seeing as i can hit 4ghz with the stock one, i'm sure i'll do bit better).

make sure you put the proper amount of artic silver 5 (i don't recommend anything else), which is about the size of a bb. ya, that small. I used a thin piece of stiff cardboard to spread it evenly and thinly on the cpu. Some peeps suggest putting it in the middle and letting the heatsink spread it around, which seems to work, but i wanted to be extra careful.

Other then that, make sure you have a decent air path to the cpu and back out the case. If you have an older case with the power supply on top, i suggest you get a new case that has the PS on the bottem. on top it's too close to the cpu.

other then that, you should be able to do better without hitting your voltages yet. unless i'm wrong, it seems to me that you want to get it OC'd as much as possible with having to adjust your voltages as little as possible.
but like i said, it's possible i'm wrong on that, and someone will correctly in a post or 2. lol

good luck

When you say you got 4ghz without changing any voltages, does that mean you left everything on Auto? If so then that is not a good idea by any means. Motherboards often heavily overvolt CPU's when left on auto and an OC applied. At 4ghz Im thinking your pushing well over 1.4V when you could easily run alot less. If that isnt what you meant then my apologies.

I mean that I up'd the blck only.

Didn't change the voltage or anything.

though i have a really good powersupply & mb, so maybe that keeps the voltages more even, which is why I wouldn't need to up the voltages so soon.

not really sure, still learning alot of about this myself.

It's just from what i've seen in posts and stuff, most the 920's OC great over air, so it would seem you should be able to get a bit better then that before you need to up the voltage, but maybe not.

I remember what happened to me at first. I had my memory set at 1600, and i hit a ceiling around 3.2ghz, and once i lowered my memory i was able to get up to 4ghz. Also, I did that with HT on, so i should be able to do better with HT off. I don't even see a difference with it off on my computer anyways, so i figure it's less overhead the OS has to deal with.

I see what you are saying, you left your voltages on AUTO. Just here me out here before jumping to conclusions. I am simply trying to help here. If all you do is up the Bclock then your board automatically ups the voltage to account for the overclock. Now normally this is ok for a LIGHT overclock but you are talking 4ghz here. That is quite a bit for this chip on air and you really have to start regulating the voltage going into this chip. I want you to open up CPU-Z and show a screenshot of what your voltages are running at. Im guessing its anywhere between 1.4 and 1.42V. The lower you can keep your voltages the safer your chip will be. Im not saying that 1.4V will kill this chip, Im just saying that if you can run much lower then you really should. Most people can hit 4ghz between 1.26-1.31V. Its always good to MANUALLY set your voltages on such high OC's. Im sorry if you already knew this, Im just trying to help here. It will also help keep your temps down quite a bit. If you dont want me to say anything else then just tell me to leave you alone. Im good either way

He must have set the voltages to auto, no way possible to get 4.0 on 1.192v!! I wish! Auto is Default setting for most motherboards, so I would fix the Auto as jrharvey is saying, since the motherboard will sometimes overdo the voltage needed and give too much, it might be +0.180V for CPU and QPI, which falls close to Intel's max of 1.375 for CU voltage and 1.35 for QPI voltage then if you ahve Turbo mode on top of those it will add about another +0.070V to the CPU core voltage which will jump you into the 1.40ish range which is high but the chip can go to 4.0 under this range. Just use the motherboard's overclocking utility to find out what your setting are

FYI P6T Deluxe owners:

If you upgrade your BIOS to the latest version (1033), it unlocks the 21x Multiplier for the Core i7 920.

More potential has been unleashed! I will see what I can come with as far as overclocking with the 21x Multiplier.
