For the Intel(R) Desktop Board D945GCCR you may use the Intel(R) Pentium(R) D 940 (sSpec SL95W only) processor which supports Intel® Virtualization Technology. The rest of Intel(R) Pentium(R) D that support Intel® Virtualization Technology are not compatible with the revision of motherboard you have. For this you can check the motherboard compatibility list here:
For information on what each processor supports you can check for the processor model here:
Concerning the laptop system you mentioned, there might be many different options for you to upgrade or replace your processor with. We recommend contacting the computer manufacturer as they have set the valid compatibility list between the computer, the BIOS and the available processors in the market. The system manufacturer should also provide the specifications on what technologies from the processor might or might not be supported.
Please bear in mind that what limits the compatibility is the computer itself (motherboard and bios) not the processor. The motherboard requires to have the proper micro code to manage the processor, if not, the system will not work, and it is the computer manufacturer or Original Equipment Manufacturer who develops the BIOS to include the microcode for the processor
dear diego_intel or other intel staff,
thanks for your help.
i check the processor for the desktop board (D945GCCR), it is "x86 family 15 model 6 stepping 5 genuineintel 3192 mhz" (i can't identify the processor number of this CPU, either with "cat /proc/cpuinfor" or "dmidecode". please help on how to identify the processor number for this CPU) and the socket type is LGA775. is this processor support virtualization? if not, as you recommend, replace it with the 940 (SL95W) onto the same motherboard, can the whole system support virtualization (including motherboard, BIOS)? the 940 (SL95W) support PLGA775 socket type, but the current "x86 family 15 model 6 stepping 5 genuineintel 3192 mhz" processor support LGA775, does this matter?
The BIOS in the motherboard at the moment has no virtualization enable/disable option (BIOS version/Date is CR94510J.86A.0045.2007.0418.1532, 4/18/2007; SMBIOS version is 2.4). what is the latest version of BIOS can be upgraded to for this motherboard for virtualization feature?
are there any other things need to check before going to buy a 940 processor to replace the current one for virtualization for the whole system? when replacing the current CPU with the 940 (SL95W) one, the cooling component need to be replaced as well or can use the current one (the power consumption of these two CPUs are different)?
this type of motherboard and processor might be too old, but please do help me to answer the above questions, and give me the firmed advice on how to upgrade the whole system to enable virtualization feature. i don't have enough budget to purchase the new computer system, so perfer to upgrade.
thank you very much for your help in deed !
On older motherboards, when the processor installed was not able to support Intel® Virtualization Technology then the option was simply not shown in the system BIOS, however being this an old motherboard, it would be hard to know if the reason is that actually the motherboard does not support this feature at all.
Please bear in mind that this product has reached its End of Interactive Support so Intel no longer provides interactive support for this product via telephone, chat or e-mail. Being this an old product, there might be a possibility that it does not support Intel® Virtualization Technology at all, you would need to test and see.
The latest BIOS for that motherboard is 0060 available at:
Now, concerning the processor, you can use the Intel(R) Processor Identification Utility which will identify the processor and tell you what features it will support, so this will show you under the advanced technologies tab if the processor supports Intel® Virtualization Technology or not:
Thanks for your help, much appreciated.
I have already upgraded the BIOS to the latest version 0060 a few days ago, but haven't upgraded the CPU (it needs to be ordered from eBay or Amazon and will take more than a week). But there is no option to disable/enable virtualization in the latest BIOS.
Can we say the desktop board D945GCCR not support virtualization at all, or it still may support virtualization, but the BIOS has no that option?
If the CPU not support virtualization, does the BIOS has the option to disable/enable virtualization? Not quite sure what is the logic of the design for the BIOS utility program?
Sorry for the desktop board being too old, but if can identify that it can support virtualization, then just need to upgrade the CPU.
When get the above issues sorted out, I can decide whether to upgrade or just buy another one.
Thanks for your help.
Use Intel(R) Processor Identification Utility available here:
For information on how to use this software check the video here:
From there check if the processor you have support Intel® Virtualization Technology or not. If it does then the option to enable VT should be displayed in your system BIOS.
Thanks for your reply.
In the page of ARK | Intel® Desktop Board DQ45CB, it shows that Intel desktop board DQ45CB support VT-d (not VTX), but in the page of Desktop Boards — Compatibility with Intel� Virtualization Technology (Intel� VT) , it looks like that it supports both VT-d and VTX. what is the correct information?
I find an Intel desktop board (DQ45CB) + Intel Core 2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB), and would like to use them to replace the ones in my current computer system for virtualization, and keep on using the remaining parts. hopefully they can fit into my current computer system, and the whole computer system can support virtualization after upgrade.
thanks for your help.
Intel® Virtualization Technology VT-x is a feature of the processor itself, which is used by the motherboard to enable Intel® Virtualization Technology VT-d on its operation. So, if the processor you install in that motherboard supports VT-x, then the motherboard basically will support it and add support for VT-d too.
Servers can be a completely new ground. You can seek for such information at Servers
For a list of processors with Intel® Virtualization Technology support you can refer to:
I see some computer systems in www.trademe.co.nz 1) http://www.trademe.co.nz/Browse/Listing.aspx?id=656079430 2) http://www.trademe.co.nz/Browse/Listing.aspx?id=656079606 3) http://www.trademe.co.nz/computers/desktops/no-monitor/auction-656079414.htm 4) http://www.trademe.co.nz/Browse/Listing.aspx?id=657324576.
All of them are with Intel motherboard with Intel H61 chipset and Intel CPU. All the systems look like do support VT.
My question is that do all of them support Linux OS, e.g. Ubuntu 12.04, both 32/64 bits desktop GUI and server?
Moreover, Intel DQ35JO + E8400 CPU support VT-D? What can VT-D actually do? Can you give some example? Is it that VT-D support nested VM creation?
For information on vt-d you can refer to this article:
Keep in mind that Intel(R) Desktop Boards support only desktop operating systems, so server edition operating systems are not supported. Concerning Linux* support, this is only supported by the operating system distributor directly.
We do not validate server operating systems on desktop motherboards, for that you need to use a server/workstation motherboard to use a validated operating system. And Linux* compatibility depends on the operating system distributor so we do not check if a given Linux* flavor is supported in these motherboards, so you need to check with the respective Linux* distro.
if the desktop board isn't made by Intel, but use Intel CPU, or the desktop board is made by Intel, but the CPU isn't, how to know whether they're compatible with each other. Are there any tools, URL links to check for these?
are ASUS P5QPL-AM Motherboard and Intel E6750 CPU compatible with each other and the whole computer system support VT?
