i7 2630 QM maximum memory

[idata]

I own a ASUS G73SW which has a i7 2630 QM processor.

According to ASUS the computer is expansible to 16 GB of memory.

It's motherboard has 4 slots, 2 of them populated with 2 x 4 GBb SODIMM DDR3 1333MHZ.

But, when I see the specifications of this processor, they say maximum memory 8 GB, but in little words - depending on memory type.

As the memory controller, in i7 generation, lives in the processor chip, and being the memory controller the one who establlishes the amount of memory supported, I am confused.

The BIOS and motherboard will certanly accept 16 GB of memory. But I am affraid that the CPU won't recognise it.

As I want to make the memory upgrade, I ask if someone can help me with this question.

Will i7 2630 QM accept 16 GB of memory, 4 x Samsung M471B5273CH0-CH9 DDRIII-1333 4096MB?

This processor will support up to 8 GB RAM, so higher than that will not be recognized.

I just don't know if you are Intel member, but if so, I think you must adverttise ASUS, because they are making a mistake announcing the upgradable capability and worst, preparing themselfs to make the upgrade of my computer in their technical services, because one of the free slots stays in the back of the motherboard.

[idata]

ASUS is insisting with me to send my equipment to their technical services in order to upgrade the memory to 16 GB.

I'm going to put this question to ASUS, saying that what they are selling to me is wrong. Worst: What they sold to me doesn't correspond to what is announced..

I presume that you Adolfo_Intel belong to INTEL staff, because you use an Intel logo as your image.

Please, confirm to me that I am correct in order that I can proceed with my claim.

Last night I put 8 more gig of memory in my AsusN53SV-XV1 that has a Intel 2630QM in it. The laptop has 4 memory slots and claims to support 16 gig total. The addition of the 8 gig brings my total up to 12 gig. The Windows 7 home premium x64 operating system and BIOS both saw the 12gig and it was usable by Win7.

[idata]

Thanks for your post Tom.

This is the reason why I insisted with a reinforced answer from Adolf_Intel.

What do you say about this Adolf_Intel?

The Bios can see the memory. That's normal and has nothing to do with CPU.

But about Windows seing it, I think taht it only is possible through the CPU.

Can you clarify me please?

[idata]

What Adolf Intel is saying is that the cpu can only avail of the the 12gb ram installed. Yes the mobo and windows recognized the rams but you have to find a way that the cpu is really using them all.

[idata]

Correction: the cpu can only avail 8 gb maximum. Sorry for the omission.

Excuse me but you are signed as guest.

Are you someone from INTEL or even Adolf_Intel?

I need to have a definitive and concrete understand about this question.

ASUS says in the computer specs that it is upgradable to 16 GB.

ASUS insists and is waiting for my computer to upgrade it, because one of the free slots is not acessible unless you dismount the computer.

Tom says that his OS recognises the phisycal amount of memory he has.

As long as I know it's the OS that makes the mapping between the virtual memory and the phisical one.

So, if CPU doesn't recognize it we will have pages of programs placed in a non acessible memory.

Worst. How can OS access it if the CPU doesn't have means to go there.

I think that OS works with CPU, not with BIOS.

Not working for Intel nor siding with Adolf Intel.

Asus is correct in stating that their mb can accomodate up 16 gb of ram.

Based on Tom's report, Windows is correct in recognizing the installed 12 gb ram.

Adolf Intel is correct in pointing out that the processor can only work or operate a process one time (this is different from recognizing) up to a maximum of 8 gb ram only.

What I'm pointing out is that a way should be found to verify that the processor can really used up the installed 12 gb ram in one task/process or verify Adolf Intel's statement.

[idata]

I don't know your name. So I'll call you Guest. OK?

What Adolf_Intel said is that the i7 2630 QM only recognizes 8 GB of memory. The rest will be ignored.

A CPU has its own address space defined for RAM memory.

The rest of the bits of the addressing space refer to ROM (BIOS), PCI, USB, Keyboard, Mouse, Printers, Graphic Cards, Hard Drives, Ethernet and so on. And when I say bits I refer even bits, let's say that a space that can contain Petabytes of addresses can only refer one address or a few of them.

This is the way a CPU addresses, or multiplexes, the assembly (opcode) instructions that refer to any peripheral component and how it communicates with it.

So, if the space defined for addressing RAM memory in 2630 QM only can refer to 8 GB, it's because the bits reserved only can contain those 8.589.934.592 memory positions.

And this is in concrete what Adolf_Intel refers, not that the processor can operate a process at one time. At least that's what I understood.

No doubt a CPU can operate only one process at one time. But we live today in a multiprocessing environment. And what makes that possible is the Operating System (OS), which is permanently giving and getting processes to the CPU. If you open your Task Manager you will see the amount of processes that the OS is keeping running. Each one has its own physical address space, defined by the OS which paginates the instructions and data of each program (process) and places them in the physical memory and in the page file or swap file, as you wish. The physical addresses will be those where the CPU can go.

The instructions of a program contain virtual addresses and it is the Memory Manager Unit which converts then virtual in physical addresses, in the form of pages of 4 KB, and manages the 3 cache levels, the RAM memory and the HD (page file). The MMU is part of the hardware in the CPU chip and is the OS which places there the values for the pages in RAM and in Disk.

As you see, the OS and the CPU work together in a perfect union.

There comes my question. How can the OS see what the CPU doesn't?

And I place exactly the same question that you do: How can we verify thnat the CPU only sees 8 GB of memory, if the OS can see 12 GB?

ASUS is sure of what it says. And their warranty is not given in a forum, where anyone can be anybody. They say it in their specifications and they confirm it through their technical services, after I called their attention to the question. And ASUS isn't properly an amateur Laptop assembler!

And our question remains essentially in one single question: Where is Intel when we need their support? How can we talk to their technical services to obtain a definitive answer to this question? Till now I can't see where. I think that a Forum is not enough to such a question. I don't even know if Adolf_Intel is a nickname, which most probably will be.

Please, if someone from Intel is reading this, give us a correct explanation about this question, but in the form of an Intel technical answer. Is it possible?

I have an ACER 7750g with 8Gb (2*4Gb) and an ASUS 1215n with 8Gb (2*4Gb) at home, I will install 16Gb (4*4Gb) into the ACER and make some tests

I will tell you more in max 10h from now

[idata]

Thank's prmvh

[idata]

I loaded the system by having

- 2 World of Warcraft logged into stormwind

- 1 vmware player running linux

- 7 notepad with a divx into each to load the RAM

the system is running Windows 7 Home premium 64bits (French)

it seems the CPU is able to handle the whole 16Gb

hope it will help

[idata]

Offcourse it helps. And a lot.

According to Task Manager, Windows sees and uses 16 GB of memory.

If you go to "Moniteur de Ressource" you can verify that the commited memory for all processes will sum the memory occupattion. That way there will be no doubt. At least that's what I see in a desktop with 6 GB and i7 920, which supports 24 GB according to Intel.

But even without that, I don't believe that there is no accordance between those values. They both belong to Windows and represent the physical value used by all processes and by each one. And its Windows which allocates the physical and virtual memory pages.

I think that Adolf_Intel has to review or explain it's considerations and that what the specifications exactly say is:

"Max memory size 8 GB (depending on memory tipe)". That observation can mean all the difference.

I send you a link to one page which talks about your computer and that I have read

http://www.notebookcheck.net/Review-Acer-Aspire-7750G-Notebook.45861.0.html http://www.notebookcheck.net/Review-Acer-Aspire-7750G-Notebook.45861.0.html

If you read the upgrading part, you will see someone else convicted that the maximum is 8GB.

I thank you very much for your cooperattion.

It should be nice to have a word from someone of INTEL clarifying this question.

[idata]

I lent yesterday my asus to a friend so I just made the test with 10Gb instead of 16Gb with 2 ram module of 1Gb each, but it's enough to show the resource monitor above 8Gb

[idata]

From the first and second picture the amount of memory utilized is from 83 to 84 percent. Can you make it go to say 95 percent?

[idata]

done

[idata]

Thanks again prmvh. Your posts have been very useful

I have no doubt about this case, at the moment.

The i7 2630 QM allows windows to allocate pages of processes in the physical memory till 16 GB.

But I insist. If someone from Intel reads this, please try to clarify the question.

In the meantime I'm going to program the upgrade of my computer.

[idata]

Thanks. From the pictures I can see that the system can use the installed memory up to 100%. But I can't say for sure that the processor also uses the memory 100% of the time during the activity shown.
