Techradar.com "It's only slightly bigger than the 920's 21x at 22x, but that extra should make all the difference when tweaking the clocks."

Now I can only dream about it as of right now... I can't believe how much money I wasted in my life-time. At one point in my life I had 15 grand but I spent most of it on food like ordering pizza all the time... I'm not fat at all in my opinion, I'm 185 pounds 5'10, I jog all the time! But it just sucks that I can think of all the time I wasted money! But maybe it was a great thing since the longer I waited the better cpus and **** came out!

For the last time.

The 930 has a 21x multiplier and then you can turn on TURBO BOOST for a 22x multi.... on one thread. (Prove me wrong if it really is all 4 cores) It's pointless, and no one that is overclocking should do it.

If you buy a 920 you will want to use the 19x multi.... unless you're ok with THINKING you are at 4ghz but really being at 3.8 on 3 cores.

Go into your BIOS. Turn off turbo boost. Now, what's your multiplier?


With Turbo Boost off, my 920 is at 21x multi.

Written by Sayaa from Foxconn -

"The return of the Turbo-Button?
The max turbo multipliers are stored in seperate registers from the "normal" max allowed cpu multipliers, and they can not be changed (unless you hack the cpu ) The turbo multipliers can not be forced to stay on all the time... at least not directly... you can fool the cpu into believing all the conditions that are necessary to run turbo mode are there, even if they are not
the highest boot multiplier is the highest "normal" multiplier...

for the i7-965 it works like this:

IF turbo is disabled
OR vcore is unstable
OR current is too high
OR Tdp is too high:

4 cores will run at 24x133=3200Mhz
3 cores will run at 24x133=3200Mhz
2 cores will run at 24x133=3200Mhz
1 cores will run at 24x133=3200Mhz

IF Turbo is enabled
AND vcore is stable
AND current is ok
AND the TDP is below the limit

4 cores will run at 25x133=3450Mhz
3 cores will run at 25x133=3450Mhz
2 cores will run at 25x133=3450Mhz
1 core will run at 26x133=3600Mhz


for the i7-940 it works like this:

IF turbo is disabled
OR vcore is unstable
OR current is too high
OR Tdp is too high:

4 cores will run at 22x133=2933Mhz
3 cores will run at 22x133=2933Mhz
2 cores will run at 22x133=2933Mhz
1 cores will run at 22x133=2933Mhz

IF Turbo is enabled
AND vcore is stable
AND current is ok
AND the TDP is below the limit

4 cores will run at 22x133=2933Mhz
3 cores will run at 22x133=2933Mhz
2 cores will run at 22x133=2933Mhz
1 core will run at 23x133=3050Mhz

so you see, turbo is really not that useful for most of the cpus, its only useful for the 965, where it basically auto overclocks the cpu... so basically the Core i7 lineup looks like this:

920 2800Mhz BUT if vcore is unstable, current is too high, or temps are too high, it will run slower.
940 3050Mhz BUT if vcore is unstable, current is too high, or temps are too high, it will run slower.
965 3600Mhz BUT if vcore is unstable, current is too high, or temps are too high, it will run slower.

What turbo really is, is a more advanced form of throttling the cpus from those clockspeeds down to a SAFE speed that will work even with high temps, fluctuating vcore and high current. instead of advertising a 3600mhz cpu that throtles down to 3400 or less depending on the situation, which would cause a lot of complains, the cpus are rated at 3200mhz and everything else above it is a BONUS, so nobody can complain"

Turbo Boost will NOT permanently boost your MHZ on more than one core.

A PC with TB on that hits 4.2ghz will not be as fast as a PC that is actually clocked to 4.2ghz.
I'm not sure what all you've read, but Intel's own white paper on the Turbo Boost technology states that it can provide a one frequency step boost when two or more cores are active and TWO frequency steps when only one core is being used.

I'm not trying to be a d*** or anything (I'm just after the truth), but I'll take Intel's white paper over "everything you've read" when it comes to this matter.

I'm talking about i7 920s and 930s, not i5s and the 1156 i7s where they CHANGED turbo boost. Either way, you guys are still all terribly wrong and I can't wait for someone with a brain to back me up.

You asked a question earlier. Disable Turbo Boost, and see what my multi was at. I told you, I disabled turbo boost, and my 920 multiplier is at 21x.

Wrong.

"When you look at the Nehalem CPUs by themselves you have to wonder what makes them so much different than the previous generation. On the left is the I7 965 Extreme Edition that features a non turbo multiplier of 24 and is unlocked both up and down. Couple the 24 multiplier with the 133MHz base clock frequency and you end up at 3.20GHz. The I7 920 is at the other end of the spectrum and has a maximum non turbo clock multiplier of 20 for a base clock speed of 2.66GHz, in turbo mode this will jump as high as 22 for a turbo speed of 2.93GHz, the same base frequency of the I7 940. To accommodate this massive chip the socket pin count is up to 1366 from the Core 2 processors 775 pin count"

Edit: I can't believe we're even having this argument... I thought this was common knowledge.

Uhhh...

That's great and all. But my Turbo is off and I'm at 21x multiplier. You're fighting a losing battle here. Quote all the forums, etc, that you want -- I know what I saw, 21x multi w/ Turbo off -- thus, not wrong, unless I happen to have a magical 920 that can do the 21x multi that you claim it cant.
