R400 - bought ddr3 1066 mhz memory but works in 399 mhz?

Hi, I own a Thinkpad R400 and recently I bought memory for her. Memory is 2 x Samsung PC3-8500 1066 mhz DDR3 1 GB and now that I'm checking CPU - Z for mem clock it says its 399 mhz running? Latest version of Memtest 86 + reports also 399 mhz DDR800. This does not seem fair to me. CPU - Z says as FSBRAM ratio is 1:2, Bus speed: 199.5 MHz and FSB: 798 MHz I have the latest version of the bios for R400 which I think is of 3.20... motherboard is 7440WHW, I don't mean to overclock any component just get whats promised. Help, please.

This may be the result of your CPU (T6670) that can be run at 800 mhz FSB, rather than the P8xxx, T9xxx, P9xxx, which can operate at 1066 mhz FSB.

    You can, but it will not help you because the FSB is clocked at 800 Mhz and 1066 Mhz how fast would be clocked at 800 Mhz.

    For example; you ve got a Ferrari but can't drive at full speed due to the alley. So why buy a Ferrari if you cannot drive faster ;)

  • Sticks of DDR3 1066 mhz 2GB x 2 clocked at 800 mhz on Satellite L500-1TU

    Hello world!

    So I bought this Toshiba laptop 2 weeks ago
    http://PT.computers.Toshiba-Europe.com/innovation/product/satellite-L500-1TU/1082331/toshibaShop/FAL...

    Sometimes, I noticed he has a few hicups when im game or on youtube, as the noise loops for about 3 seconds then its normal again.
    I was scared, it was a defect in the ram and ran memtest and CPU ID

    But even if the memtest did not get any errors, I noticed something, the mem test and the CPU ID say that the RAM is running at 800 mhz, when they are both DDR3 and should be run at 1066 mhz...

    Here are screenshots from CPU - ID
    http://img63.imageshack.us/GAL.php?g=96346130.PNG

    As seen on CPU - ID, the laptop runs with 2 slots of these:
    http://UK.computers.Toshiba-Europe.com/innovation/JSP/individualOptions.do?service=UK&OPTION_ID=1059...

    Also, I went into the BIOS and there is no way to change the frequency of the RAM.

    In addition, all pilots, including the BIOS are up-to-date.

    Could this be a fault of the laptop?

    >... and CPU-ID say the RAM is running at 800 mhz, when they are the two DDR3 and should be run at 1066 mhz...
    Why do you think they should operate on a 1066 MHz?
    If the speed of the motherboard FSB 800 MHz faster RAM modules will be slow to run on 800 MHz only.
    Believe me that everything is OK with the modules of RAM.

  • Satellite L40 - 13G has 667 memory but works at 533

    Satellite L40 - 13G have original built in 2 x 512 667 of memory but memory works only at 533, why is this?

    I flashed the latest 2.20 bios of the Toshiba site.
    I did an upgrade on this model by changing its processor,
    Original image was celeron M 440 and now is core 2 duo T5600,

    The chipset on this model is 945GM and it supports core2 duo processor.

    Now main FSB is 667 for the cpu but memory works only at 533 dual Chanel
    and it's strange because the memory is 667?

    BIOS doesn't have a Setup for memory clock.

    Thanks for the help!

    Hello

    If you have read your question, you will get a response.

    Your machine comes with a Celeron M, which has a FSB of 133 Mhz. This means that the whole machine has been designed (including the BIOS!) to work with that CPU and JUST with this CPU regardless what the chipset is capable of. This means that no matter what CPU and memory you´ve installed in your machine, the FSB will collaborate in the FSB 133 Mhz (533 Mhz), but your Coreduo needs another front bus.
    And because the BIOS is programmed to put the FSB 533 won´t never be able to do your mem running at 667 Mhz. Maybe if you can reprogram your bios.

  • EliteBook 8440p; DM1-3020us: 2x4gb 1600 MHz DDR3L works in Pavilion DM1 but not Elitebook 8440p? But both are supported than 1066 MHz RAM

    I have two Elitebook 8440p PCs that both run an Intel i5 520 m (although one of them has a discreet Nvidia NVS 3100 m, while the other does not and use the integrated graphics card Intel).

    I also have a Pavilion DM1-3020us with an AMD E-350 APU; It's the only other PC I own which takes SO-DIMM DDR3 modules.

    I just bought this Crucial DDR3L 1600 MHz 2x4gb hoping to use it with the 8440p without the graphics from Nvidia:

    http://www.BestBuy.com/site/crucial-2-Pack-4GB-1-6GHz-PC3-12800-DDR3L-so-DIMM-Unbuffered-non-ECC-lap...

    However, it causes crashes and BSOD as soon as he tried to start under Win7 64 bit on both 8440 p PCs.  Also when trying to boot Linux Mint 18 I empty a kernel panic, and run Memtest86 + just leads to restarting the PC within seconds.  Yet, I can navigate through the BIOS throughout the day and it will continue to work very well...

    But here's where it gets really weird - the RAM works perfectly fine in my laptop DM1 Memtest86 + and Win7 64 bit (I use it as I type this).  What's curious?  Because both the AMD E-350 and the Intel i5 520 m only support up to 1066 MHz RAM!

    The only thing I can think is that there is something wacky where RAM is unable to operate at 1066 MHz at 1.5V or is not able to run at 1.5V to all E-350 1.35v support (and 1.5V RAM so that the i5 520 m only supports 1.5V) which itself would be really strange that Micron (which actually manufactured the RAM) States on their website that their 1.35v and 1.5V RAM have actually the same die (a bit like mobile i7s quad vs quad I5S Office) and that both can operate at 1, 5V, implying therefore that the 1.35v product is simply a higher binning:

    https://www.micron.com/~/Media/documents/products/technical-note/DRAM/tn4114_ddr3_1_35v_1_5v_compat...

    Crucial live chat support, however, closed several hours for the day, so I thought I would at least make this post in the meantime.

    Hello:

    Please see this thread, and the discussion that I posted in this thread... and you'll have your answer.

    6550 b has the same chipset as the 8440p.  I posted the link to the site from NewEgg for the memory, you need to buy if you live in the USA/Canada in the discussion that I've referenced to the other person who had the 8440p.

    http://h30434.www3.HP.com/T5/notebook-hardware-and-upgrade-questions/RAM-memory-modules-that-actually-work-for-HP-EliteBook-8440p/m-p/5570634#M335108

    There are several discussions on this issue if you want to find even more.  Everything is solved by specific G.Skill memory I posted.

    The extent of why it works in the dm1 and not the 8440p, the chipsets are different.  The Intel chipset in the 8440p doesn't support voltage DDR3L.  Comparison of AMD and Intel chipsets are like comparing apples and oranges.

    I also believe that the chipset amd in the dm1 is more recent than the chipset in the 8440p and promotes low-voltage memory.

    I have just return from memory and use the gift card on something else.

    I doubt that Best Buy has this specific memory.

  • Profile of Alienware Area - 51 ALX Intel XMP A10 does not work with DDR3 1600 MHz

    I bought three Kingston 8 GB RAM DDR3 1600 MHz 240 pin DIMM that totals up to 24 GB of RAM and install in my desktop computer. When I turned on and the message appeared saying:

    Maternal health and infant is running with DDR3 - 1333 MHz

    WARNING! Previous overclocking failed, and system restore its default value. Press F1 to continue, F2 to enter Setup Menu

    When I access the BIOS setting (version A10), I disabled XMP and then it went through fine after the reboot. However, I have to have XMP allow at any time? How can configure profile 1333 MHz to 1600 MHz XMP?

    What bothers me is that I had three former PIN of Kingston 4 GB RAM DDR3 1600 MHz 240 DIMM which total up to 12 GB of RAM and the XMP worked very well with them before they were 1600 MHz.

    The type of computer I have is:

    Alienware Area-51 ALX

    Intel Core i7 980 Extreme 6 c with 12 MB of Cache

    Windows 7 Ultimate

    Please, help me to solve this problem. Thank you.

    http://en.community.Dell.com/Owners-Club/Alienware/f/3746/p/19471694/20209913.aspx#20209913

    And I certainly don't have the answer, but I'll remember these points:

    1. I think that you can set manually nothing XMP adjustable (but with more control).

    2 machines often memory need to be slowed down when you are near maximum capacity look maintenance manuals.

    3 area-51 has never been tested or even allow the 8 GB DIMMs. You are in the new territories.

    4. If you really need 24 GB (and it works at 1333) then the 267 speed drop is insignificant.

    BIOS it detected as PC-8500. CPUZ shows like PC-10700 work clocked at 533 Mhz (= 1066 MHz DDR).

    The processor is Intel Pentium Core 2 Duo E 8400 3.06 GHz with FSB 1333 MHz.

    WIndows 7 operating system

    1. Why does is not able 1333 Mhz motherboard @ full speed?

    2 working memory @ 1066 MHz @ 7-7-7-20 VS memory work @ 1333 MHz @ 9-9-9-24, which is better?

    Khelifi

    Sure... While theoretically fastest speed of memory should be faster, there is little or no difference in the overall performance of the memory. The memory CASE latency generally increases the rated speed increases. Latency means basically 'backwardness' and this latency to counterbalance the gain by increasing the speed. Still, you would never notice a difference between the two.

    I am currently using Lightroom 4. I bought the IMac with the largest memory, but he has quickly filled. To conserve space on my computer, I bought a hard drive and I tried to get my lightroom back up there. (I don't know if I did it correctly or not) Now, all my photos in Lightroom are "offline or missing", and I have no idea what to do next. Any help would be greatly appreciated.

    I guess you mean not memory and disk space, you want to clear space on the internal drive. Is this correct?

    If you have moved your photos somehow (this is not a backup), please follow these instructions to reconnect photos in Lightroom. Adobe Lightroom - find folders and files moved or missing

    In addition, you must (it is obligatory) make real backups of your database catalog and photos, that means accurate identical copies, made by a method automated and placed on a different physical disk than the originals. Lightroom allows you to make backups of your files of catalog on a regular basis, it is an option under the catalog settings. To make backups of your photos, you need some third party software to do.
