Memory speed (BIOS) running

2 sticks of memory installed on my HP Pavilion (model #: p6605f) are: 2RX8 PC3-10600U-09-10-B0 (M378B5673FH0-CH9) that makes them a 1333 Mhz memory... BUT when I run the HP Support Assistant, he says:

4 GB installed memory

1: 2 GB 800 Mhz Samsung other DIMM Slot

Slot 2: other DIMM 800 Mhz Samsung 2 GB

Why my memory runs at 800 Mhz , when supposedly he can run up to 1333 Mhz ?

Is this a BIOS setting? (I don't see anything in the BIOS that would allow me to control the speed of the memory)

The BIOS on the PC says:

Installed memory: 4096 MB/PC3-6400

1: 2048 MB DDR3 SDRAM memory bank

Memory Bank 2: 2048 MB DDR3 SDRAM

BIOS version: 6.05 12/08/10

Basic version: 08.00.15

Thanks for any help.

The reason why he turns to this speed is because the primary and secondary memory timings have been preset in the BIOS file for optimal value that was determined by HP engineers.  You can change this, but it would violate your warranty and require that you Flash a BIOS hack on your desktop-card mother s.

A module of memory will be a SPD table encoded in its firmware, which tells a BIOS what timings should be used at speeds of different buses.

To display SPD settings available for your modules you can download and run the utility CPU-z.

HP, Dell and Sony and other OEM computer manufacturers set the BIOS so it cannot be easily modified. 'S done it for a simple reason, although some might find offensive. This is to protect consumers from themselves and to ensure that their products continue to function reliably. Most of the people looking at the BIOS settings available in my gaming system (an ASUS ROG Crosshair IV) and say "it's a bunch of settings" (or worse! ). The industry feels and probably rightly, that the average PC/computer laptop/touchpad user didn't just need to be able to screw up their PC with just a few keystrokes.

  • U350 (Intel SU2300) memory speed question

    Hi all

    I was wondering, is there a way to increase the speed of the memory in u350?

    Module of memory in my u350 is Hyundai ddr3 rated at 533 mhz (1066 mhz ddr) but it works

    by default, only 400 mhz (800 mhz ddr).

    is cpu maybe limit it?

    TNX for the answer

    To exy s initial question:

    "Supports the module memory, chipset (Intel GS45 supports almost certainly it) I do not have.

    See a reason why ram should run at low speed and then he pointed to work to... »

    Modules are designed to operate at different speeds.

    The processor and chipset are designed for low power usage.

    Memory speed is equal to the lowest energy consumption. (And more strict timings of memory)

    Looks like a good choice for me, FSB/MEM = 1 / 2 = 800/400

    Most of the laptops I've seen opt for low mem speed and better timings.

    (6 6-6-18 vs 7-7-7-20 for example)

    And not a very noticeable difference in performance, IMO.

    But looks like a design for low power usage decision.

    I'd be willing to bet that you get very good battery life.

  • Fix for 580 1333 or 1067 MHz memory speed?

    I plan on adding memory to my six year old, Inspiron 580 for a few years of life out of it.

    When I enter my service tag and run the parts finder, Dell suggest adding DDR3 SDRAM - DIMM 240 pin, 1333 MHz (PC3-10600).  However, when I ran the Dell system detects, it says my memory is DDR3-SDRAM (1067 MHz)?

    In addition, said Dell web site my my service tag-based maximum configuration is 8 GB but the documentation with my 580 says 16 GB.  Because I am running Win 7 64 bit, I guess that 16 is correct as it is in agreement with Microsoft on Win7 64 bit OS.

    In a related question, can I add a 4 GB DIMMS with the other three 2 GB DIMMs (10 GB in total) or do I need to use a 4 x 2 + 2 x 2 configuration (12 GB total).

    Thank you

    Scott

    The specs say that you can use either 1066 MHz or 1333 MHz RAM.

    Crucial recommend actually 1600 MHz RAM for this model. And the good thing is that they guarantee it works or they take it back.

    Don't forget that if you mix RAM with different speeds, all of it will run at the slowerspeed. Thus 1333 and 1600 MHz RAM can operate at 1066 if you leave the old 1066 RAM installed

    What about the max RAM, card of the Dell for the 580 say:

    Accessible DDR3 DIMM Sockets internal memory four connector

    Capacity of 1 GB, 2 GB and 4 GB memory module

    Type of memory DDR3 1066 MHz or 1333 MHz DIMM; memory non - ECC only

    Support for configurations of memory: 4 GB, 6 GB, and 8 GB

    Win 7 64 bit can handle 16 GB of RAM, that does not mean that your hardware is supported by that much. The amount of RAM supported depends on the BIOS and the Intel chipset on the motherboard.

    There is a demand in this thread that someone installed successfully 16 GB in the 580, but there is no way to verify that.

  • Satellite P25-s607: max memory speed

    I plan to upgrade my memory to the phone of p25-s607, he saya in the spec that the memory is ddr 266
    someone told me that the chipset is 885 pe so the card mother shoud suport up to 400 mhz,
    is it so? and if I put it ddr 333 (or 400) going to work at these speeds?

    Hello

    The chipset is Intel 865PE and ICH5 with data/address Bus width; 64-bit / 32-bit
    In addition, this device was shipped with 512 MB of DDR SDRAM and you expand to 2048 MB
    Memory expansion: 128, 256, 512, 1024 MB, 2.5V, SODIMM, DDR PC2100 SDRAM

    Unfortunately I have not found information on the memory clock speed, but as far as I know, you can use these Kingston modules:
    Kingston KTT3614/128 128 MB of memory
    Memory of 256 MB Kingston KTT3614/256
    KTT3614/512 Kingston 512 MB of memory

  • Satellite Pro A100 - 828 Max memory speed

    Hello

    Can someone please tell me the max speed of memory for Satellite Pro A100-828, I'm wanting to move to the 4 GB maximum but is some sites say the maximum speed is 533 MHz while others say to 667 MHz. For example, the Toshiba site lists only memory 533 MHz under the "Compatible" Options yet other sites list 667 MHz memory as compatible.

    Thanks for your help.

    Hello

    You should check which bus (FSB) front would support.
    Install the hardware diagnostic tool like Everest home edition, and you should be able to find this value.

    If your chipset would support 667 Mhz then you can use these modules and the modules would go with 667 Mhz too.

  • Sat Pro 2470 memory and BIOS update

    I recently received from Win XP SP 2 installed on the laptop and the free memory is very low (64 internal, additional 64 installed)

    With XP, I can't find the option to choose start in DOS at the next startup. Is this also necessary when I add memory?

    Hello

    I don't think that you should remove all files with Windows XP.
    Simply insert the modules of memory and power on the machine.
    Updated the BIOS normally does not increase the available memory.

    What modules you have installed exactly or let's say what is the exact number of them?

    Generally these tools like CPU - Z or something are not so important. If everything works well, forget it. ;)

  • Leak memory in cRIO running RT

    I am running RT 2009 on a compact chassis of RIO.  My very basic VI causes the RIO to restart, which seems to be linked to a leak memory.  I use system monitor and you can watch the use of memory on the chassis of RIO grow very slowly.  Attached is the project and the target VI is pretty basic.  I even made the change to close the refence that opens when analyzing data, but I still have this persistent problem.

    chOff,

    The next thing I would look at, it's how you use the "allocate Array for entry Module.vi.  Based on the help of this function and this reading, I don't think you are using it correctly.  I'm sure it is planned to use this function outside the main loop.  Your vi called repeatedly in the loop.  Whenever you call, it allocates another segment of memory.

    Yes, it will, however, 32 bits may be more efficient. If your Vista Enterprise 32-bit, you will not be able to upgrade to 64 - bit. You will need to do a fresh install.
