I7 + Bootcamp + Win7 = Only 4 cores???

So I just got a Macbook Pro i7 and put 64bit Windows 7 on through Bootcamp. When I go to check the number of cores running on the Windows side there are only 4 listed. I've done a few tests with other programs on it and nothing seems to use more than 4 cores.
Anyone have issues with this?
Is there any sort of fix?

4 physical cores is what a "Bloomfield" Core i7 is, and you can't count virtual or logical cores.
In msconfig there are advanced boot options to enable all cores. I assume you checked there also?
Also, to reduce power and heat, some of the Core i3/i5/i7 have some cores disabled and HT disabled. And that is what 620Ms have done. And obviously not 9xx as found on desktop PCs.
Processor and memory
2.53GHz Intel Core i5 processor with 3MB shared L3 cache; or optional 2.66GHz Intel Core i7 processor with 4MB shared L3 cache
http://support.apple.com/kb/SP581
Still doesn't say WHICH Core i7 family model. And I don't know laptops, nor does Apple really like to get into all the technical side of things. So I turned to Wikipedia, I strongly recommend looking there.... it is very useful!
2.66 GHz Intel Core i7 (620M) with 4 MB on-chip L3 cache (15" and 17" only)
Then you can look up what the Intel Core i7 620M features.
http://ark.intel.com/Product.aspx?id=43560
There is a lot you can do for yourself on your own to answer basic questions.
.... and there you see just how Apple and marketing may seemingly short-change the unsuspecting that assumed their 4-cores were physical and not logical threads...
Launch Date Q1'10
Processor Number i7-620M
# of Cores 2
# of Threads 4
You would need a desktop (iMac Core i7) to get 4 physical cores. Not only would it eat battery time to nothing, they require large cpu cooler heatsinks to dissipitate all that heat.
Intel Mobile Family of Core i7s
http://ark.intel.com/ProductCollection.aspx?familyId=43402
In my book, that 620M is a dual-core. Afterall, the 4-core Mac Pro Nehalem would otherwise be called "8-core" which it is not. And the dual processor 8-core would be a 16-core (but those are THREADS annd VIRTUAL CORES or can also be called LOGICAL processor cores).
Sleigh of hand, anyone?

Bootcamp win7 secondary screen brightness

Hi,
I have a macBook pro with bootcamp (win7-64) and a secondary screen connected trough the hdmi. The brightness of the secondary screen changes constantly, seems related with the content of the same screen. For example, if i have opened a photo, wich is mainly dark, and I maximize a program like Word, which is mainly white, the brightness changes a lot. this problem doesn't happen in laptop screen.
The win7 brightness control seems to affect the laptop screen only.
How to disable this annoying secondary screen brightness auto adjust?
Thanks

This seems like it applies:

MBP Late 2011 i7 2760qm under W7 only 2 Cores/4Threads

Hi !
I´ve installed Windows 7 Ultimate 64bit on my MacBook Pro Late 2011 (Intel i7 2760qm).
Under OSX 10.8.2 i have all 4 Cores/8 Threads, but under Windows i have only 2 Cores/4 Threads (Data from CPU-Z and Task Manager) and it seems to be limited to 2,4 GhZ (no Turboboost under Load).
Why is this? Have i done anything wrong with the installation?
Is the CPU limited under Windows?

would make sure to make the hardware driver disc in bootcamp in osx and install the apple windows drivers
my imac have 4 cores and with hyperthreading 8 in windows 8 and windows 7 before that

Hello Everyone,
I have a MacBook older model with me.I am running 10.7.6 on that, I was trying to use BootCamp to install windows on my mac. Since BootCamp can only work on a single Volume, I partitioned my Hard Disk to one volume.
Using BootCamp I installed windows and everything worked fine. After installing windows and testing everything, I switched back to OS X and this time I tried to make another partition on my single portioned Mac volume and named it Backup. That too worked. Now I have three Volumes
1)Development2)Backup3)BootCamp.
Next when I switched to Windows, It should the classic error, No Bootable device found, please insert a Bootable CD and press any key. When I tried to enter my Mac OS X install DVD and by pressing option key, it does not show me the proper Mac OS X development volume. It keeps going back to the No bootable device found message.
Any help will be much appreciated
Regards
Mithun

you can't add a partition in between - you put Windows to a new partition number.
GPT (GUID)
EFI
Mac HFS
Lion Recovery
Windows
And now you have two HFS
One partition and one Windows (plus Lion Recovery).
If you were to have more, it can't be before Windows for one thing.

Oracle utilizes only one core out of 8 core's.

Dear Team ,
We have noticed that, in oracle database server Oracle processes uses only one core and that goes to 100% usage remains are at idle possition thats the reason the Oracle performance is very poor some time system haults and needs to be started
Please suggest if you can have best solution,
waiting for your valueable response.

It is often slower running processes across CPUs (e.g. 5 processes on 5 CPUs with 15% CPU utilisation per CPU), than running these processes on the same CPU (e.g. 5 processes on 1 CPU for a 75% CPU utilisation). See Non Uniformed Memory Access (NUMA) for some details on why this is the case.
The kernel deals with CPU scheduling. It decides which process/thread to execute on which CPU. From a s/w perspective, one can code "processor affinity" into your s/w to bind a process or thread to a specific CPU. Oracle only does this with Oracle XE - as this is one of limitation of the free version of Oracle's database s/w. Oracle uses default kernel scheduling for Standard Edition and Enterprise Edition versions.
Oracle uses the number of CPUs/cores to determine the processor load it can create. It does not force its processes to run on a single specific CPU (with XE being the exception).
So "blaming" Oracle for what you are seeing? You are blaming the wrong layer in the s/w stack. You are also very likely misinterpreting what you are seeing.
The #1 reason for poor Oracle performance is shoddy code. Code that you and your cohorts write and run in Oracle. And that is a far likelier candidate to blame for shoddy performance, than blaming Oracle and the kernel's process scheduling across CPUs.
And you have provided not a single shred of evidence that points to a SMP scheduling issue across multiple CPUs/cores.

Second mac in cluster uses only one core

Hello all. For some reason the second computer in my render farm is using only one core out of eight.
I'm using 2 Mac Pros linked together directly via giga ethernet wire. Mac one is a Quad Core 3ghz. Mac two is a Octo Core 2009 model. Both computers have the same version of FCS3 with different serial numbers.
In the Qmaster preferance pane: Mac one is set to "Quickcluster with services" with the check boxes for Share and Managed next to "Distributed processing for Compressor" checked. 4 instances selected and "Include unmanaged services from other computers" checked. Mac two is set to "Services only" with check box for Share next to "Distributed processing for Compressor" checked. 8 instances selected and "Include unmanaged services from other computers" checked.
I hit submit in Compressor, select the name of the cluster from Mac one, then in the Batch Monitor I see the video divied into 10 sections with Mac one handling 4 and Mac two handling one. On Mac two I see that the cores aren't fired up 100%, more like 30% on average.
I did a test earlier with a dual core mbp, and again only one core. How do I get my Octo core to use all 8 cores?

Solved the problem. The solution was simple, but somehow went under my radar. On Mac two in the Qmaster preferance pane next to the "Options for selected service" button, the selected service was set to off.
Duh

T440s - i7-4600U CPU - ONLY ONE core operating :((

Hi,
I am an owner of Thinkpad T440s ultrabook, which has Intel i7 4600U CPU installed (exact model is 20AQ006BMC - the one with GeForce 730M graphic card).
Regarding to the documentation on Intel website, this CPU should have 2 cores and 4 threads (Hyperthreading). But when I start CPU-Z utility, it shows me, that I have only one core and two threads available. Same thing displays my process manager in Windows 8.1 - 1 core and 2 logical processors.
Any ideas, what could cause this problem?
Thank you.

I have found review of exact same model (as I know, they differ in few other details like 3G modem etc.): http://www.notebookcheck.net/Lenovo-ThinkPad-T440s-20AQ006BGE-Ultrabook-Review-Update.120211.0.html
And there is also screenshot from CPU-Z utility and there it shows correctly 2 cores and 4 threads:
So any idea, what could be an issue? Should I use warranty service? because it looks to me like a broken CPU

Right people, I really hope you can help... here's the story:
I produce with a friend and approx 4 months ago we both upgraded to brand new MacBook Pro's each and Logic Pro 9 each.
I bought a 13" MacBook Pro with 4GB and the 2.53Ghz Intel Core 2 Duo processor.
He bought a 15" MacBook Pro with 4GB and the 2.66Ghz Intel Core i7 processor.
We both have bought the full version of Logic Pro 9, both done the upgrade to 9.1 and have both set our copies of Logic to 64 bit.
Why? The only advantage you have from 64 bit is that Logic can use more than 4 GB RAM - which neither of you have. I would strongly recommend setting Logic to 32 bit. On both Books. It might alleviate some or even all the problems - I hope.
Here's a list of unavailable features in 64 bit mode:

My friends copy of Logic on his Mac is so buggy its sometimes unusable.
My mate is about to throw the **** thing out of the window and buy Cubase!
More often than not it is hard to install new software on computers that have been thrown about.
Can anyone shed any light please??
I think 32 bit is your answer. However, the mobile i7 processor does at least have one issue with Logic:

Equium A110 - 252 (PSAB2E) - Only one core is working

Have a Equim A110-252 running Vista Home premium. Only one core working. BIOS set to core multi-processing enabled.
Bios version V5.20
Any ideas?

It appears this model came with XP. Did you install Vista or upgrade to Vista?
Perhaps you need to install or update the Intel Chipset Driver, or install the Value Added Package.

Does logic use only one core fore bouncing?

When I bounce a project the CPU activity shows only one core working at full level. The other seems to sleep? Can you confirm that?
Thanks Eddie

Anybody out there????

Motion 5 using only one core

Why is motion 5 using only one core during heavy renders, even when all other apps are closed?
Version 5.0.3

coz it uses the GPU to do all the graphics stuff. The cores are only used to process project data.

IOGear KVM + Apple aluminum keyboard + Bootcamp + Win7 - SOLVED

I've read many posts from people who had the same problem I encountered: the Apple aluminum keyboard does not work with the IOGear KVM on a Mac under bootcamp. Everything works perfectly on all other PCs, and everything works perfectly on the mac with bootcamp/win7 using any keyboard other than the apple aluminum keyboard.
The symptoms are that the mac/bootcamp/win7/ combination simply does not seem to recognize the apple aluminum keyboard: the caps lock light does not work and typing seems to do nothing -- although the keyboard still works to toggle the KVM between systems. With some hardware combinations, the keyboard may be temporarlily recognized after a cold start, but the problem always returns with switching between systems. I first noticed this behavior with Win7 and the bootcamp upgrades (in my case, 3.2). In my case the problem occurs with a wired aluminum keyboard, but I think a wireless keyboard would exactly the same.
I have found what I believe is the root cause and the solution.
=========
The cause
=========
The cause is a failure to properly detect the type of machine attached to a KVM port: by default, the KVM auto-detects which kind of machine is attached to each port and auto-switches that port to PC mode, Sun mode, or Mac mode. Usually this works fine, but something in the latest OSX/bootcamp/win7 drivers causes the Mac to appear to the KVM as a PC, so the KVM attempts to present the apple keyboard as if it were a PC keyboard.
I'm guessing that this whole issue might be associated with the new ability for bootcamp to let you switch the behavior of the top row of function keys between apple behavior and PC behavior -- which obviously introduces an emulation layer -- but I could be wrong. If there is anybody who has this same problem without bootcamp installed then it could be a more generic driver issue. Fortunately that doesn't matter, because the solution is the same in either case.
============
The Solution
============
All these IOGear autoswitching KVMs share the same logic, so this method should work for all. The manual for one of the simpler models of IOGear KVM is available at www.iogear.com/support/manual/GCS634U.pdf
The first thing to know is that the manual is incorrect in its description of how to use the numeric keypad to enter hot-key-mode (HKM): the manual says to hold down the "clear" key for 2 seconds, then add the "-" key for one second, then release the minus key and the clear key in quick succession. Unfortunately, this technique rarely works: one second is much too long to hold down the minus key. Instead, hold down the "clear" key for a few seconds, then just tap the "minus" key as quickly as you can, and then release the "clear key." You will see the LED flash on the capslock key, and you are now in HKM mode and can change settings on the KVM. To fix your problem you simply need to execute (HKM) (F2) on the proper port as described below.
First switch your KVM so it shows the screen of the Mac where you are having keyboard recognition problems: the correct port will now be "active" on the KVM. Put the KVM into hotkey mode and press F2 -- this will override the default autodetect setting for this port, and will set it directly to Macintosh mode. Your keyboard will immediately be recogized (and the capslock light will work!). The KVM will remember this until you change it or reset it to its factory configuration.
If you need to troubleshoot you can use another hotkey combination to print out the current settings of the KVM: open a text editor and position the cursor inside it for typing, then execute (HKM)(F4) -- the KVM will "type" its current settings. Here are mine on a 2-port KVM immediately after setting my Mac Mini port
= = = = = = = = = = = = = = = = =
hotkey:
(num lock)+(-) and (ctrl),(ctrl)
os setting:
port1 pc
port2 mac
kb:
port1 english
port2 english
= = = = = = = = = = = = = = = = =
It took me two whole days to research and test and resolve this problem, and I've read many other posts from people who couldn't find a solution & went out and bought new keyboards or different types of KVMs. I hope this posting can help somebody else avoid that difficulty.
Good luck!

Magic Trackpad pairs with Bootcamp (Win7) MBP instead of another MBP w/Yosemite?

I've 2 MBP's - a Yosemite MBP and one running Win7 via Bootcamp. When the Yosemite MBP is off, the Magic Trackpad pairs with the old MBP (Win7/Bootcamp). I see no clear way to disable this pairing in Win7/Bootcamp or a clear way to disable Bluetooth on the Bootcamp/Win7 MBP either. I can shut down the Win7/Bootcamp PC, but this gets old very quick, as I tend to carry my Yosemite MBP w/me at the end of the day.
Any suggestions from the Mac Geniuses? Thank you.
Martin

Based on the multiple issues, I think I would reinstall OS X 10.10 from the recovery disk (your data is untouched). As always though, make a good backup before doing anything (I use Time Machine and I also make a bootable clone).

Bootcamp: Win7, not enough memory.

I mainly run Bootcamp: Win7 for gaming such as StarTrek Online and it generally runs well. However, often when playing StarTrek Online I get a little message from the computer in the upper right hand corner telling me the game is "running in reduced textures due to low memory." I have 8 GB of memory installed on the MacMini. This is the maximum the mini can hold and should be sufficient. Has anyone experience this problem?

This sounds logical. Do know if the video memory in a MacMini can be adjusted? I have a feeling it can't and I'm at work now so I can't check. Perhaps in the Windows settings I could tweak it? Thanks!
Update: I read up on it... it's a shared system memory thing. So, no way to allocate.
