Yes turbo is enabled... I don't know if it is the chip or my board. I have an i5 750 that should arrive soon and I'll be able to test it as well. If it still doesn't work then I'll be contacting EVGA.Quote:

PolRoger: It's possible your ES processor doesn't support turbo mode. I wrote a quick little program that just checks the bit in the CPU to see if turbo mode is available. I'm not sure if this will give you any new information. Maybe you could try it too KURTZ and see what it reports when turbo is enabled and when it's disabled in the bios.
KURTZ: What does that show if you disable turbo mode in the bios?
My i5 750 went in today so I'll have to wait untill the X3440 is remounted to see what your program reports on the ES chip, however I seem to be having the same problem now with my i5. If I disable "turbo" in BIOS your program says the i5 is "not supported" if it is enabled in BIOS " Turbo Boost" shows that is supported. That being said I still can't seem to get the turbo multi to function with the i5 either so I'm thinking the problem lies with this particular motherboard.Quote:

I just updated it for these new CPUs so give it a try.

Load your CPU with Super PI or what have you and hit the Boost Now button and see what happens.
I don't know if it will help your problem any but I know it can't hurt to try it. Your CPU seems to be saying that it supports turbo boost so it might be a hidden setting in Windows that is holding you back.

22x onto the 860? M/B MIIIF cpu level up in the BIOS can allow to set the 22x multiplier ... :S possible? with my Xeon (eVGA FTW) the max is 21x ...

If I "disable" turbo it will show a speed of 4000Mhz in BIOS and of course so does CPUZ/Eleet in windows. I'll probably now go and post about this issue at the EVGA forums...

Some mainboards might do the same thing with i7-860 / X3460 CPUs. If there is an option in the bios to use a 22X multiplier then selecting this will automatically turn on turbo mode at the same time.
PolRoger: There's a model specific register (MSR) within the processor that sometimes gets set to the wrong value by Windows or the bios. This register can control the multiplier you end up with.
http://www.fileden.com/files/2008/3/3/1794507/MSR.zip
My MSR Tool lets you read this register so you can compare to other users to see if this might be where the problem is. Run the above program and type in 0x199 in the MSR Number box and then click on the Read MSR button and send me a screen shot. Maybe you can do the same KURTZ.
Make sure EIST is enabled in the bios and go into your Control Panel -> Power Options and make sure the Minimum and Maximum processor state are both set to 100%. I got lucky with the DFI and was able to find a work around but I might not be so lucky with this problem.

Ok, but why my friends can go @ 26x (w/Turbo on single core) with their i7-860? i can get only 25x (like you can saw in the shots that i've posted in the RT's thread)Quote:

anyway, i've checked into my BIOS and like you said if i enable the Turbo Mode i've got the 22x133 only in the BIOS (never saw in the OS), obviously if i disable the Turbo i've 21x133 in the BIOS and in the OS ...
edit: this is with 'BALANCED' Performance in the OS

You'll have to post some links to your friend's CPU.Quote:

If you have all 4 cores enabled in the bios, the multiplier will constantly cycle between 25 and 26. You can use a program like i7 Turbo and calculate the average multiplier which has some meaning.
When 4 cores are enabled in the bios, CPU-Z and ELEET might report your maximum multiplier at 26 but it is not steady at 26. It's constantly dropping down to 25 or lower depending on how many cores are active at any point in time. Ask your friend to send a screen shot of CPU-Z and i7 Turbo at the same time when CPU-Z is reporting a 26 multiplier and I will show you what's really going on.
i7 Turbo reported a multiplier of 25.248 in the screen shot you posted in the RealTemp forum. The only way the average multiplier can be greater than 25 is if it is spending some of its time at 26. With C3/C6 enabled, your multi is definitely spending some time using the 26X multiplier but with 4 cores enabled in the bios, it is not possible for it to spend 100% of the time using the 26 multi. Don't be confused by CPU-Z or ELEET reporting the maximum multiplier. That only tells part of what's really going on inside your CPU.
Edit: The 0x00000016 in MSR 0x199 is in hexadecimal so the equivalent in decimal is 22. The default multi is 21 and setting this to one more than 21 is asking the CPU to use turbo mode. The CPU gives back the maximum turbo boost it is allowed to use based on how many active cores you presently have and whether C3/C6 is enabled. You can also read MSR 0x198 which tells you what multiplier the CPU is using but I'm not sure what multiplier it will show on these new CPUs when multiple bins of turbo boost are available. That's why programs that depend on reading MSR 0x198 are not always accurate, especially at idle or when lightly loaded.
i've asked to my friends, so when i've some feed-backs i'll post their shots here ... :)Quote:

like you can see now for the first time i saw the 26x multiplier, BUT isn't always @ 26x ... most of the time it stays stuck @ 25x ...
Disable C1E and make sure in the Control Panel -> Power Options your Minimum processor state is set to 100%. Run Super PI and it should be a constant 26X when 3 cores are disabled in the bios and turbo mode is enabled. The 17.497 number that i7 Turbo reports shows that your multiplier is not at a steady 26 at idle. You need to make those other adjustments until it is steady.
Dear Uncle you're simply THE MAN!!! :DQuote:

so no troubles here? :P
just another little Q for you: i've this option in my BIOS:
C State package limit settings
- Auto
- C1
- C3
- C6
- C7
what means and what's the better? thank you so much ... :)
See, I just don't make this sh_it up. I knew there was a 26 multi hiding in your CPU. :up:
It's all those other programs that like to ignore what's really going on inside your CPU that ends up confusing people. It's hard to rely on CPU-Z / ELEET when it can report the exact same multiplier even though internally, the CPU might be doing two different things.
I use the Set minimum processor state option to control the multi at idle. I don't usually enable C1 because it can cause the floating multiplier problem if other things aren't set correctly.
C3/C6 are needed if you want more than a +1 multiplier when running single threaded tasks. If all you want is your multiplier locked at +1 then enable turbo and disable C3/C6. You don't need it and it can be a problem when overclocking if it is cycling your multi up to 26 times.
C7 is a deeper sleep state so if you like to save power and are using C3/C6 then enable C7 too and see if you like it. Lots of users like a nice steady multiplier so I always recommend using i7 Turbo so the multiplier you think you are getting is actually what you're really getting. Setting something in the bios isn't always what you end up with in Windows.
Edit: You should be able to turn on hyper threading so you will have a speedy single core Xeon CPU that can process two tasks at a time. Go do some Super PI benches to show us what you get.
Thanks to Shamino over at the EVGA forums... I have now resolved my lack of turbo with this chip. It turned out that I was missing some jumpers on the P55 FTW motherboard which was keeping the multi locked at x19. With the jumpers in place the turbo is now functioning correctly. :up:
Next: onwards to push for 4.0Ghz.

So in a nutshell, is the X3440 and the i7 860 similar/identical?
Nope. The X3440 only has a default multiplier of 19 and the i7-860 has a default multi of 21.

Well, I know that. But will it be the overclock the same? How about the performance and thermal?Quote:
