• Win7x64 Home Premium does support double physical CPU (Xeon 3.4) with HT - to see only two graphics in the CPU monitor.

  I have a workstation Dell Precision 670 with dual Xeon 3.4 GHz CPU with Hyperthreading.  I installed Windows 7 x 64 home premium and now cannot see two processors/cores in the system monitors backed up by the release of Registry.  This means that two physical processors or hyperthreading is not supported by Home premium.  I didn't know that this referred to in one of the official literature I've read (and I thought that all the flavors supports two physical processors).  Can clarify you if it of Dual CPU support or lack of support of HT for my processor (I think they're Prescotts of memory).

  Here is the result of a record query, it seems to list the two physical processors and not virtual cores HT.

  UPDATE: -.

  (Turning things and disable in bios), I confirmed that I see in the Task Manager, msinfo and CUP-z 1 physical processor with 2 threads.  BUT in Device Manager I see all processors & carrots (4) and all report that they function normally.  So it seems to me there is a missing communication between the end user of things and what is seen in the Device Manager.  I tried the option in msconfig to force 2 CPUs, but that made no difference.

  You need Pro see two physical CPU slots, double or not.

• ESXi 6.0 physical CPU change

  Hi all

  This is my first post in the forums and will gladly start to participate more now that I'm working a lot more with vmware products

  My question concerns the change of physical processors allowed for ESXi 6. If my memory doesn't fail me ESXi 5.5 has been licensed for 2 processors physical (we have two processors in our ms), and we started to update some of them to 6.0. Now, after having entered the ESXi license, we noticed a difference (large and small) in what he says that he has been approved for...

  

  Someone please tell me they just made a mistake, because if they did, it's a step unhappy return in my opinion = / (and we will have to keep 5.5 on our servers)

  Thank you all!

  Kind regards

  Martin

  I just ran a quick test. I installed ESXi 6.0 with a single processor as a virtual machine and is joined with the license of the hypervisor. He showed "1 physical CPU" as a license. I then shut down the machine virtual and added a second processor. After starting the virtual machine, he showed "2 physical processors", as a license (as expected).

• 2 physical CPU considered 4 CPU in ESXi

  Hello

  I had a problem on a UCS B200 M4 blade. the blade contains 2 physical CPU E5-2660 [email protected] (10 carrots each)

  ESXi 5.5 u2 (with or without custom image cisco) installed successfully.

  But ESXi 5.5 see 4 physical CPU with 5 cores of each instead of the 2 physical.

  I have no idea why, maybe the bios features but do not know which?

  Someone has an idea?

  Thanks in advance.

  Hello

  Is the question on the community of cisco. It seems that the E5 v3 adds a new feature called COD (Cluster on Die).

  Unfortunately this feature is not supported by VMware for now (even in u2 5.5).

  It is possible to disable in the bios.

  Thanks for your help.

• Virtual desktop CPU limitation 2

  Hey, I seem to face the question of which need more CPU by virtual desktop.  Well I assigned 2 processors per virtual machine and now I want to give the VMs 4 processors.  VCenter well seems to me assign 4 and in device manager 4 introduce yourself on the virtual machine.  Unfortunately the virtual machine only seems to be using 2 processors.  Everyone knows this?  If anyone has any information that will help me get on my VMs 4 processors, it will very much appreciate with gold stars :).

  Thank you

  W7 can have a maximum of 2 physical CPU (vCPU 2).  Now with 4.1 you can divide the 2vCPU by 2 cores, so see 4 logical processors within the guest OS.

• Distribution of load among the groups, only one thread limited to physical CPU (& memory)?

  I was not able to discern, documentation, I read so well how the load of a virtual machine is distributed should the load exceeds the limits of one CPU heart.

  At what level is the distributed load between the physical processors cores and especially between physical servers?

  At the level of the Virtual Machines,

  At the level of the process.

  At the level of the threads, or

  Somehow secondary thread?

  I'll ask another way; the ESX provides virtual processors that exceed the capacity of the hearts of single-processor or single servers, which also has the ability to run a single thread that consumes the entire capacity of the virtual processor?

  Can someone point me in the right direction?

  There is good documentation for this issue?

  AiwarikiaR-

  I don't think that it is wrong, unless you only have 1 VM.

  If you have more 1VM, with the processors maintain will almost always help them performance.

• Browser Konqueror for Linux has a CPU limitation function useful for Web sites using Flash content. You can add such a feature in Firefox?

  I recently discovered that browser Konqueror for Linux can help the user to limit the CPU usage while visiting a Web site using flash technology by changing the settings in the Flash section and by adjusting the slider settings VERY HIGH to HIGH and AVERAGE and so on. It actually works and it doesn't have a direct impact on the overall performance for flash player, but it can lead to conflicts if other such extensions that add blocker or click-to-flash are also enabled.

  Maybe you can add a similar setting in Firefox in the browser or just as a useful addon or extension option section.

  Hi Michael,
  I love the sound of that. I found an add on which has Visual for the CPU usage as well as can be useful

• Re: Satellite C660-2R3 CPU limitation to 978 Mhz?

  Hi all

  5 days ago, I bought a Toshiba Satellite C660 2R3.

  The laptop has core i5 2.4 GHz and 6 GB of DDR3 memory.
  However, I am very disappointed by its performance.

  I run CPU ID/CPU-Z and it turns out that the laptop is limitation up to 978 MHz Core speed to 99 MHz, Bus speed.
  I checked the Bios setting for the purpose of limitation of decommissioning.
  But was surprised to see there is no option to do so.
  You have only a LOW constant and automatic something.

  WHY TOSHIBA? WHY?
  Its like buying a Ferrari, but you can only drive at 50 miles per hour?

  Does anyone know of a work around that? I would appreciate your help.

  Thanks in advance.

  Hello

  You are right. The laptop seems to support the Intel Core i5 - 2430M processor with Intel Enhanced speed Step technology.

  Enhanced Intel speed step technology allows the system to dynamically adjust the frequency of voltage and average core processor, which can translate into a reduction in consumption and a decrease in heat production average. This is the reason why the CPU does not always work at the highest level, but this speed depends on its use for laptop and it will be adjusted automatically by the system

• X 220 cpu limitation problem

  We have now confirmed that X 220 CPU is constantly limitation to him is the lowest State even when a performance max profile is used, even that hip. This likely affects the T420/s / T520 too and maybe even of W520. The direct effect is reduced random write (most important) ssd (and maybe same hdd) speeds, but who knows what else he is touching. I see no limitation in cpu - z while playing music and youtube videos with dxva.

  This isn't something new and not unique to Thinkpads; There are a few generations of Intel chipset. What is unique to Sandy Bridge Thinkpad is however that the settings of Windows that take care of it in other books does not work here. The only way I found to stop the strangulation is either disable Intel Speedstep or CPU power management in the BIOS. The first is a radical movement as it locks the processor speed/power and the disadvantages of energy consumption are obvious with that. Disable CPU power management is more subtle, but it also has significant effect (less) about the life of the battery. This is the correction for the limitation because it uses the desired speed without constantly falling down to state the more low, but then on the battery, even the State of lowest cpu active it uses at least 2.5 - 3W more when it is activated.

  The solution looks so much like it should take the form of an update of the BIOS. Unlike other power in the power manager controls / BIOS, CPU Power Management (and Speedstep) cannot be stopped / worldwide, not separately by energy source.

  
  

• XPS 600 CPU limitation

  I read a lot of forum and does not seem to find a definitive answer to this problem of limiting CPU.

  First XPS 600 a card mother Socket 775 and I read that you can simply replace the CPU with any processor that uses the same socket (for example Socket 775: Intel Pentium D, Pentium 4, Celeron D, Pentium Extreme Edition, Core 2 Duo, Core 2 Quad).  Is this true?

  If the answer to the first is false, I also read that the processor speed higher than XPS 600 motherboard can handle is Pentium D 965.  Is this true?

  Thank you much for the help.

  
  

• comparison of physical CPU and vCPU cores

  Hello

  I'm an admin of VMWare and recently asked by a customer in our Cloud Computing environment to add an extra vCPU to one of their virtual machines so that it aligned the physical counterpart that they had migrated away from more.  The physical version had 2 processors quad core (clocked at 1.4 Ghz) and the virtual version has now 2 vCPUs (The ESXI host a 2.4 Ghz CPU).  Since then, I've been asked how to compare the two and I am struggling to explain their project...

  The user connects to the physical computer and run the Task Manager and sees the 8 cores working away

  It then records in the virtual machine and see the two processors working away.  You can say that he thinks that the performance piling in ESXi...

  How to compare the two scenarios and how can I explain that is comparable in an ESXi environment - and is it really comparable?

  The way I see it, adding a second processor on the virtual computer which means provide 2 physical processors on the host are available, instructions can be performed on them by the customer, which means that 2 at the same time.

  On the physical server, the 8 cores can be used simultaeously then, how this can never be comparable?

  Or I have this completely wrong?  Performance and the remains has never been my strong point!

  Advice or answers on the above would be welcome

  Thank you

  Hello.

  Each vCPU is mapped to a logical processor, which is a physical on your host system kernel if you do not have active Hyperthreading.

  I don't like the physical to virtual comparison, but of course I know my clients.

  In most cases, the physical resources have never been effectively used, as the operating system or application running on the top was not able to use the 8 cores of the two processors for example four hearts in your example.

  So most of the time you can get the same performance with only 1 or 2 vCPUs after moving to virtualization.

  If you want to know more you can read the resource management Guide: http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-501-resource-management-guide.pdf

• is this setting for VMs cpu limitation cause performance hit for ESX server?

  We had recently come vmware consultant do a health check.  One of the things he mentioned briefly that we should change is that we should remove the limitations of cpu that we fixed for VMS.  His reasoning is that it causes needless overhead on the ESX servers.

  I was wondering what were the thoughts of everyone on this, I thought that the limitation of the cpu was a good thing because he stopped to a virtual machine in addition to cpu utilization... All opinions are appreciated.

  I agree with shishir08 here, the limits should be carefully thoughtover and only be implemented for specific vm:s.

  Why limit a machine if there are resources available for this purpose to consume?

  However, I think that the actions and reservations always should be applied.

• 8 physical CPU cores - how can I use all cores effectively?

  I have a couple of servers Dell PowerEdge 6950.  Each server has 4 sockets to dual core for a total of 8 physical cores.  I will be the host of many servers Windows 2003 server and 2008 Standard edition.

  If I set each virtual machine to use a single virtual processor, this just drop a load on a carrot and let others 7 carrots wasted, or it covers the single virtual processor between all eight physical cores load?

  One of my virtual machines will be host to a MySQL database using a fairly heavy CPU load and I want to exploit the full potential of my servers.

  Thank you

  the vmkernel Scheduler will cover all UC hence it will be used effectively.

• What is the difference between virtual and physical CPU cores?

  I understand one is virtual and the other is physical. My question is, if I run a physical system with two physical processors quadricoeurs, which would be an equivalent virtual machine configuration, assuming I use VMware on a dual CPU quad-core server?

  Would be - this 4 x vCPU or 8?

  Run perfmon to see what treatment power is actually using a period reasonable period (x days)...

  You generally assign virtual servers less vCPU than you should in physical cores before conversion, or building a VM... Where you had processors dual core quad now, the reality of things would be that it is really only with the power equivalent of two hearts (crete)...

  Beauty to go with a virtual server is that you can assign a n vCPU VM start (for example, two for a multi-thread aware or SMP, application server) and add later if the performance requires it. The majority of the VMS is built with one vCPU to start, unless you KNOW (beyond doubt) that demand on the server will need vCPU more and the software running in the VM actually fully benefit the granting of vCPU more to her... I have, in general, set the alarms I know where the application of the CPU is abnormally high (or above the normal threshold) on VM (email is sent)... This allows me to monitor the requests to the server and adjust it accordingly.

  You can also grant a greater share value VM for resources, so it has a higher priority than the other virtual machines when he needs these resources.

  Of course, there is much to be said for having a host server (for ESX/ESXi) who has enough power too... These days, I wouldn't recommend becomes a new server (for a production environment) with anything less than the Interior, dual Xeon 5620... Larger environments might require higher speed Xeon 56xx or maybe even 65xx or popular 75xx Xeon series with more cores per socket... This is a capacity adequate session/run planning would have come into play...

  Virtual machines are limited to 4 vCPUs unless you upgrade to Enterprise Plus.  In this case, you can configure 8 vCPU VMs.
