difference in speed of upgrade memory P7-1154

Hey there.

I am running the original 1333 MHz, 6 GB of RAM that came with this computer.  I am maxing out the RAM, in speed and size, this Christmas.  Yet, I am running in a quandry.  Information for my PC from the HP site says that my p7-1154 can take 1333 and 1600 1866 MHz for the RAM, but the 1866 MHz are listed as PC3 14400, although the real to 1866 x 8 multiplier is 15000, more or less... with only 1800 MHz multiplying to 14400.  I have two questions.  First of all, PC3 15000, 1866 MHz RAM will work in this machine, or is it mandatory to use only PC3 14400, 1866 MHz RAM?  Secondly, is it possible to ensure that any new 1866 MHz RAM I buy will run to 1866 MHz (I've met at least one person here who has my computer model even and new, faster than 1333 MHz RAM no were limited in speed to 1333 MHz)?

Thanks for any response.

Yes, to 1866 MHz, exact transfer rate is 14933⅓ or 14900.  Yes, 1866 MHz (PC3-14900) will work in your motherboad and no, it is not required that you install only memory PC3-14400 (1800 MHz). Although your motherboard and processor supports 1866 MHz memory your BIOS may limit the memory speed at default speed SPD 1333 MHz. OEM manufacturers like HP are not easy to use BIOS, I mean that you have will limit BIOS that does not allow the user to manually set the settings like overclocking the memory or CPU etc. So it's really a gamble. The memory will work but will run at low speed rather than the nominal amount of 1866 MHz. So, try either go with 1600 MHz or 1333 MHz. The speed difference is not noticeable that so stick to the speed lower is the best option IMO.

Good luck with the upgrade. Send us an update, how it will be if you go with memory 1866 MHz. Cheers, mate!

  • Upgrade memory 667 Mhz for Satellite U300

    Hello

    I have a new Satellite u300-11v and I was hoping to upgrade the memory standard modules of current 2 x 1 GB 2 x 2 GB ddr800 for a max speed of memory. However, after looking at intels site for specifications of the chipset for my machine (its got an intel mobile GM965 chipset) it seems that it will only support up to 667 mhz RAM modules.

    Reading a little further, I think that if I have a memory at 667 mhz bus it can only be reached through the module 1 x 2 GB at 667 mhz. Currently I put 2 x 2 GB 667 modules in the machine, the default memory bus at 533 mhz.
    I watched chipset specs of your laptop (945GM) while I was on the site intels and your in the same boat as me.

    Heres so the dilemma: you have just 1 x 2 GB 667 MHz memory to get this speed little extra memory or go for 2 x 2 GB to the slowest to 533 mhz to accommodate all these massive windows page file.

    For me, have family Vista premium running on a machine that can bring together only a bus 533 mhz memory with 4 GB of ram is not acceptable while I will now go back to XP pro which is not so heavy on resources.

    Did you really notice the difference between the memory 533 MHz bus and memory 667 MHz modules?

    Of course, there is a small difference in performance, but you will never get a performance gain by using the modules of 667 MHz instead of 553 Mhz modules.

  • Upgrade memory for T61

    Hi friends,
    I have a system of 7663-xxx T61, with 1 GB PC2-5300 667 MHz RAM. My Front Side Bus 800 MHz (I think!), software Everest says my memory controller is capable, dual channel and ~ 85% physical RAM use. I have a nVidia Quadro NVS 140 M 128 MB graphics card, but Everest reports 512 MB?

    I want to update my RAM and buy some online.
    one) should I buy a similar 2 GB RAM PC2 - 5300 for my system performance, running Windows XP 32-bit? If so, should I buy Lenovo RAM only, for the maintenance of my 3 years warranty intact?

    Will assume the ROM ThinkPad and Lenovo ThinkPad and Lenovo warranty portable systems limited

    (b) what are the alternatives best for good quality, reliable laptop computer memory, not to mention that Lenovo?
    (c) wouldn't it be better if I'm able to buy RAM that can match my FSB? This will have a performance advantage? Do these similar exist FSB RAM speed?
    Please suggest manufacturers of memory superior, as appropriate.
    I couldn't find any Lenovo 800 MHz memory on their Web site.

    Kindly help me to solve my problem to upgrade memory.

    I'm a mechanical engineering student, so I have not any idea of FSB and similar, so I ask the scholars members to throw light on this area.
    Info on online sites in the United States, with fast delivery will be very appreciated.

    Thanks in advance.

    Honestly, you'll be fine with either / or. I've not had a bad experience with Samsung never, if I had to choose I'd give it a very slight preference based on prior use.

    I doubt that you (or me) would be able to tell the difference between two identical machines, execution of memory with different CLs...

    I hope this helps.

  • PROTECTED M400: Question about upgrade memory

    Hello

    The M400 comes standard with 512 MB, I bought an extra 1 GB and installed in the second slot. I can't honestly say it has made a huge difference in speed, but I guess when I run intensive applications I could see some difference in performance.

    In any case, I was wondering, does make a difference which slot guard what memories... e. g would make any difference if I put the 1gig module in the slot A and 512 in slot b?

    At the location of the moment, A contains 512 and slot b contains 1gig.

    Thank you

    Hello

    As I know there should not be much difference, but it is recommended to put the largest memory module into slot a. Please don t ask me why.

    If you want more performance to disable all processes running unnecessary and also check MSCONFIG and disable the startup items, you need not.

  • upgrade memory in a Portege 3410ct

    I tried installing memory of 128 MB PA3034u 3410ct, but on commissioning a message comes up saying that the ACPI BIOS is not fully compliant with the ACPI specification.
    I downloaded the latest BIOS setings but makes no difference. Will not start just yet. Clues as to correct the problem, other that not upgrading memory.

    Hello!

    This problem may occur if you add the memory (RAM) to the computer when it is in hibernation.

    When the computer comes out of hibernation mode and load the file Hiberfil.sys, Microsoft Windows detects the change in the State of the memory, and then you receive the error message.

    To resolve this issue, restart your computer.

    If the problem persists, start the computer by using an emergency boot disk, and then delete the Hiberfil.sys file.

  • Tecra M4: upgrade memory PC2-4300 or Pc2-4200?

    The Tecra M4 can take the Pc2-4300 and 4200 to 533 Mhz

    So is there a difference of speed between the two types. I just want to get the fastest memory for my machine, but the 4300 is almost twice the price of 4200. I don't know what to do.

    Thank you

    Hello

    I found in the official document that Tecra M4 supports these modules:
    DDR2 400/533 256 MB (PA3389U - 1 M 25)
    512 MB DDR2-400/533 (PA3412U - 1 M 51)
    1 GB OF DDR2 400/533 (PA3411U-1M1G)

    Another description:

    256 MB of memory DDR2 PC2-4300 (533 MHz) (PA3389U - 1 M 25)
    512 MB PC2 - 4300 DDR2 (533 MHz) (PA3412U - 1 M 51)
    1024 MB (1 GB) DDR2 PC2-4300 (533 MHz) (PA3411U-1M1G)

    I put t know why but if I searched the web for this part number: PA3411U-1M1G
    I found a PC2-4200 and PC2-4300 under a same module, strange.
    Please compare these two sites:
    http://shop.EUROLAB.at/product_info.php?products_id=1226129
    http://www.technoworld.com/productdisplay.asp?ProductID=22800

    In addition if you want to buy a good memory, I suppose to buy a Toshiba or a module of Kingston because there are much faster and have a better performance as a module of memory name No.

  • Upgrade memory - 4100XCDT

    Hello
    I am the proud owner of a 4100XCT satellite.
    I have upgradet the HARD drive on a 30BG drive.
    I also tried to upgrade memory (RAM live) but the 256 MB Dimm PC133 so-built by A-Data, with I ordered seems not to be compatible with the laptop. (The system no longer starts when the new RAM is installed.)

    An update of the BIOS would help solve this problem?
    And: RAM that is compatible with this laptop? (Is there a witch of memories 256 MB are compatible?)

    Thanks for reading.

    Hi Katzenfreund

    The nice thing about Toshiba and memory upgrades, it's that we don't need to think about what technology or the speed to use. Just use original (recommended) or search in the referencetable of the provider to use, their module that is compatible with the partnumber Toshiba memory you want.

    Toshiba PA-numbers for the 4100 are:
    PA3004U - 64 MB
    PA3005U - 128 MB

    Good luck

  • Upgrade memory to the Satellite Pro A120-185 PSAC1E

    The original installed memory of 1 GB in my trusty old A120 is now become a bit of a factor limiting and I want to upgrade to the full 4 GB. I checked this site and it says that the memory runs at 533 MHz.

    However, looking at various other sites suggested that some varieties of this laptop can run memory running at 667 MHz - according to its region!

    Anyone knows which is the right speed?
    Obviously, I want to put a faster RAM in it when I update, but if we can't run it, I don't want to waste money I can't use memory especially.

    Thanks in advance.

    Tony

    Hello

    > However looking at various other sites given to think that some varieties of this laptop can run memory running at 667 MHz - according to its region!
    Depends on the FSB (front side bus)

    If the FSB would allow the 667 Mhz, then the modules of memory also would go to 667 Mhz. If the FSB supports only 533 Mhz then your modules will be run max 533 Mhz even though the modules support 667 Mhz.
    Simply said; the FSB can slow down the speed of the memory.

    Hi chiefcc

    You can install up to 8GB 1x8GB, the procedure is in the manual (page 61) and check the format to see if this applies to your computer

    Use the module memory 8 GB which can be found in the manual of your laptop or certificatesas Kingston.

  • HP Pavilion dv7-6c05ev: upgrade memory (M471B5273DH0-CK0 to M471B5173QHO-YK0?)

    Hi all!

    I have a Pavillion DV7-6c05ev. The product number is A8V36EA-B1A.  I'm trying to upgrade memory. On board, there are two modules of 1.5 volt. (2 GB Samsung M471B5773DH0-CH9 and 4 GB Samsung M471B5273DH0-CK0 and they work ofal channel). I am buying a second module M471B5273DH0-CK0, to have 8 GB dual channel.  I ordered a new, but I got a Samsung M471B5173QHO-YK0 instead of CK0. The YKO runs on 1.35 v and 1.5V, but I'm afraid to pair them up, because maybe something could go wrong with tensions. I found another store and ordered again CK0, but again, I received YKO. So now I have two new YKO. What do you think is it safe combine the old with the new KATE CKO (sellers insist that KATE is the replacement of CKO and will work fine on 1.5V, it will automatically choose the correct voltage. And the other question is, as long as I have two YKO, can I use these two as a pair?  There are exactly the same, but it is made in China and one in the Philippines, but I don't think it's a problem. And replace the two old memories? Is the compatible with my model M471B5173QHO-YK0?

    (I found another seller with CKO, but I did not want to risk again. From what I understand, they have the old code on their pc, but there is a new, replacement, M471B5173QHO-YK0, and they ship the other. The question is if I can match up with the old CKO and return the second YKO, or keep two YKO and use them with my laptop).

    Thank you in advance.

    Kind regards

    Zeta

    No this is essentially the same thing. The 11 first is the latency CASE and the second number is not really speeds, but the SPD versions and then the B4 is just an internal reference to manufacturers for the memory form factor. The computer will see these 2 identical modules.

    It would have been great if the 520-1050 TS came with its maximum in memory of 8 MB instead of 6 MB, but no problem, it can be upgraded.

    My question, it seems 2 types of memory upgrades can be used and wanted to find who I use because I've always loved my systems to memory max. The specs on the upgrades memory say the following:

    -==============================================

    Boxerm, welcome to the forum.

    Given that the motherboard supports the memory dual channel, you will need to replace the existing memory.  It seems that there are only two slots.  So, you want to buy a set (2 x 4 GB = 8 GB) you ensure that you have dual channel.  Dual channel is faster.  I would buy the PC3-10600 (DDR3-1333).  Here's a good explanation of the speed of memory.  If you're like me when I started to learn about the RAM, most of this information is difficult to understand.  However, it will give you a good learning experience.

    I suggest to use the Crucial memory.  Here is the memory they recommend for your computer.  Recommended memory is guaranteed to work or it will be replaced free of charge for you.  I had read the entire page, as it provides good information.
