DDR2 PC2-6400 vs DDR2 PC2-6300

I'd like to max out my Mac Pro as far as RAM. This machine is mainly used for still graphics, not motion if it matters. In my case would I notice a difference between DDR2 PC2-6400 and DDR2 PC2-5300 DIMMs. Are the 6400's worth the extra cash?

32gb on the previous model? And I thought just 16. Then I'll have to rethink all of this. I may only max out one bay for now then. I'll definately get the 2x4 DIMM's and not the 4x2's, so that I can squeeze in as much as possible.
BTW, I do plan on another machine this year, but will be keeping the current one also.
Edit in: what did you mean by "4 x N"?

    HI guys ,
    Please i wanna to know does my [toshiba a200-10w|http://gulf.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?LNG=13&service=AE&PRODU CT_ID=127560&DISC_MODEL=1] supports DDR2 PC2-6400 RAM, because i need to upgrade my ram but all i found in the market is DDR2 PC2-6400.
    I already got 1 module 2GB DDR2 PC2-5300 installed, so if i get on 2GB DDR2 PC2-6400, it will work or not?
    And if it will work does the dual channel feature will work?
    About the HDD what is the maximum HDD capacity i can in stall in the same model because i'll get 1TB , so this will work ?
    PS : my OS is windows 7 professional ..
    Thanks much guys ..

    Hi
    The notebook supports the Intel 945GM chipset.
    This chipset seems to support max 533MHz.
    So if you would plug 667MHz memory modules, then the system would still works at 533MHz.
    The modules are DDR2 so I dont see any reasons why the dual channel should not work in your case.
    >About the HDD what is the maximum HDD capacity i can in stall in the same model because i'll get 1TB , so this will work ?
    Notebook supports SATA interface. The SATA controller has not limitation to the HDD size so theoretically you should be able to use such big HDD but to be honest; I never used such big HDD. The biggest one which I used in by notebook was 500GB and this was big enough.
    However, you will need to test it to b e100% sure.

  • DDR2 PC2-6400 AMD/Toshiba

    Hey everyone. I am a first time poster here. I know Toshiba won't listen to me here, but for anyone that has any
    Knowhow of Toshiba laptops hopefully can give me some information. So I have a Toshiba A215-S4757 which I have owned for a while. I love my laptop to the point where I bought another Toshiba model for my brother. I am a very good customer if a company sells me a good product. But Toshiba has done something to my laptop that has me rethinking about buying Toshiba again and I want to know why. After I bought my laptop, I upgraded the ram to DDR2 PC2-6400 with 5 CAS. (Kingston kit KVR800D2S5K2/4G from newegg). At the time I was still running the initial bios release. I don't do bios updates until a problem affects me. I saw there was a bios password glitch going around with the A215-S4757 so I updated to bios version 1.70 at the time. Which from 1.20 had a load of changes. New video bios, fixed possible password glitch and other things. Today I wanted to see what more has changed with the laptop bios in just the change log. I see that from 1.80 and up the ram is now forced at PC2 5300. It's bad enough I have to use a oem bios that they get to enforce this. I will not upgrade of course to keep my ram at the faster speed. The only thing the change log says is "The memory bus frequency was set to the PC2-5300 specification based on AMD recommendation." That same update claims "chipset register was modified to fine tune WLAN performance based on AMD recommendation". So can someone explain what the bright reason for slowing the ram speed was? Is it possible to get an full bios for this machine from Toshiba? I don't care to much, ill stick with 1.70 bios. But I want to know why they did this?

    I don't think that's it Chris.  If you check out the Change History for the bios for that system you'll see that it is a global change.

  • Replacing the PC2-5300 DDR2 667 MHz RAM with the PC2-6400 DDR2 800 MHz RAM?

    Good afternoon,
    I'm currently thinking about purchasing a MacBook Pro 4,1-2.5 GHz Intel Core 2 Duo that has 2 GB of the PC2-5300 DDR2 667 MHz of RAM, but has a BUS speed of 800 MHz. If I do purchase this machine I plan on replacing the 2 GB of memory with 4 GB, but I was wondering if anyone knows if it would be possible to put in the PC2-6400 DDR2 800 MHz model of RAM instead of the PC2-5300 DDR2 667 MHz model of RAM? The reason why I'm asking this question is because the BUS speed in this "early" 2008 MacBook Pro model is at 800 MHz, which is why I'm thinking the PC2-6400 800 MHz of RAM might work. I would appreciate any helpful and productive insights to my question that anyone could give me. Thank you.

  • MSI P7N SLI Platinum and OCZ DDR2 PC2-6400 SLI-Ready Edition

    Hello,
    I have a MSI P7N SLI Platinum nForce 750i SLI motherboard and I would like to inquire if it is fully compatible with OCZ DDR2 PC2-6400 SLI-Ready Edition memory? Firstly, I do not seem to get the correct timings with the default settings, speed is not very good, after 5 hours of running Memtest86+ there was 30 errors. I have never had the memory crash and games seem to run fine, but the memory feels much slower than it should be. Is the memory supposed to work fine with this motherboard and I'm just imagining everything? I don't know if I'm also supposed to be worried by the errors Memtest86+ returned?
    Thank you in advance for any help.

    Quote from: Del UK on 07-September-08, 05:44:14
    If memtest returned errors, yes 
    Well, there does not have to be a problem with the memory just because it returned errors. There could be many other explanations why there are errors.
    Quote from: Jack the Newbie on 07-September-08, 08:04:45
    Jacobl, please post full system specs.  Read the >>Posting Guide<< to get an idea of the details you should provide.
    How many modules of what capacity do you have?  What are your current RAM-related BIOS settings?
    If you have more than one stick of RAM, please test each stick seperately with memtest86+ and see if the errors are caused by one of the sticks only.  Otherwise there is no way to tell if there is a compatibility problem or just a faulty memory stick.
    Please post a link to the OCZ product site and also a screenshot of the CPU-Z "SPD" tab.
    I have this memory: http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_6400_sli_ready_edition_4gb_dual_channel.
    This is the rest of the components as instructed by the forum post you linked to:
    Intel E8200
    MSI P7N SLI Platinum
    OCZ DDR2 PC2-6400 SLI-Ready Edition 4GB Dual Channel
    Gigabyte Geforce 8800GT 512MB PCI
    500GB Western Digital SATA
    SATA DVD burner
    Windows XP SP3
    Antec 500W PSU
    I usually troubleshoot components step by step - eliminating all possible reasons until I have found the solution. My first step was to post here to find out if there are any known compatibility issues with the motherboard and memory. I adjusted the memory timings with a slight overclock because the motherboard did not load the default timings by default. I will start by adjusting the BIOS settings, check if the memory is inserted into the right DIMM slots and then test the memory sticks one by one. But to answer my own question: I think the motherboard and memory should have no compatibility issues and it must be something else.
    Quote from: Freestate on 07-September-08, 23:06:36
    I have the OCZ 6400 Fatal1ty modules 2x2 GB that is very similar of the ones you ask.And they are running perfectly but i must set the epp latency and voltaje values in BIOS! The simple modules of ocz are in the memory compatibilty list i thought that the SLI and Falal1ty modules are just the same with a little boost.
    I had to set the right timings also. As far as I know, the SLI and Fatal1ty modules are probably the same, just with a little boost. I think it would be very strange if a module with the name "SLI-Ready Edition" and a Nforce 750i motherboard would not be compatible together.
    Anyway, any other advice on what steps I should take? I assume by now that the motherboard and memory should work together without problem. Sorry if I started out bad by not following the posting guidelines on the forum.

  • PC2-6400 ddr2 800mhz memory running at 667mhz

    I have the T9500 800mhz cpu in the dv9700 pavillion laptop. I don't have the options in the Bios to change the speed of the memory, although it seems that the memory should be running at 800mhz and not 667mhz. Does anybody know how to change this??
    This question was solved.
    View Solution.

    Hi:
    That is correct. 
    The mobile intel version of the 965 chipset only runs the memory at 667 MHz and the desktop version of the 965 chipset runs the memory at 800 MHz.
    A little known fact but it is what it is.  See page 12 of the datasheet below.

  • Mixing RAM question...

    Up to now all the RAM I have installed has been PC2-4200...
    Went to the store and asked for 4Gigs of PC2-4200 and was given 4Gigs of PC2-6300...
    Crucial website states that PC2-6300 is compatible with my Power Mac...
    Just want to know if mixing the two is OK...or am I asking for problems...

    Okay, I added the Kingston pc3200 and everything worked fine.
    There were some differences in the benchmarks.
    On the SiSoft Sandra memory bandwidth test, the difference was minimal at changing RAM Bandwidth Int Buff from 4791 MB/s to 4796 MB/s  and the Float Buff from 4785 MB/s to 4782 MB/s.
    The PC Mark2002 test was, however, better. The memory test went from 9430 to 9793. As a refference of gain, I tested the system when I put it together and with no DOC and the default BIOS settings, the memory scored 8441.
    For the fun of it, I ran a 3dMark2003 test. I lost a little on this one, but that may be due to the fact that I have the case open. I installed a fan on the side cover to blow fresh air directly onto the RAM and NorthBridge and with the cover off, the fan needs to be unplugged. So looking at my core center I can see the NB temp is up to 116 F, which is about 8 to 10 degrees higher than with the cover/fan on. My 3dMark test scores went from 6012 to 5802. I don't know if the addition of the memory would do this, if it is form the cover/fan thing or maybe 3dMark2003 just doesn't like Mondays :P
    So there is a difference, but probably I probably won't be able to take advantage of it. I will leave it in for a few days and see if there is a "seat of the pants" difference, whether it be better or worse.
    I would love to hear people's input on these "results" or any suggestions.

  • Thinking about upgrading my T61P

    My T61p is not booting and I am thinking about using this as a reason to:
    1. Moving to Windows 7 from Windows XP
    2. Increasing the RAM to as much as my system allows
    3. Installing a larger hard drive.
    My question is how much RAM and what kind is compatible with my system.
    The current hard drive is a SATA.  What hard drives can I use?

    If you will be using 32-bit windows 7, you won't be able to address more than 3GB, no matter how much you install.   If you are using 64-bit, you can use 8GB.   You need DDR-2 RAM that is PC2-5300 or faster. Faster RAM (PC2-5400, PC2-6300, etc) will run at PC2-5300 speed. Some people prefer certain brands. I use whatever is cheapest. You can use any SATA 2.5" drive that is 9.5mm thick.  Again, some people prefer certain brands.  I prefer Western Digital, Fujitsu or Hitachi.

  • Can I Use DDR2-533 (PC2 4200) ?

    2x Kingston HyperX 2GB KHX4200S2LL/2G DDR2-5300 (PC2 4200)

    Kappy wrote:
    PC2-4200 RAM is not PC2-5300 RAM. The former is DDR2 533 MHz and the latter is DDR2 667 MHz. You cannot use the former if your computer requires the latter. Your model requires DDR2 667 MHz PC2-5300 RAM, not PC2-4200.
    Actually it should work but with what should be an obvious performance penalty. I've tried it (used PC2-4200) myself on my late 2007 model when I was bored and had access to some PC2-4200 modules from another computer that was upgraded. I've read the Intel chipset datasheets, and they've always had backwards compatibility in mind. The MacBook4,1 designation is for the last of the Intel chipsets. I'd also take a wild guess that the NVIDIA chipset versions might work with PC2-4200, although it's been reported that they work with PC2-6400.
    If PC2-5300 is mixed with PC2-4200, it should read as DDR2 533 in system profiler. The default when speeds are mixed is to run both at the same speed. I tried all sorts of combinations including 2 GB (PC2-5300) + 512 MB (PC2-4200), 2x512MB PC2-4200, 512 MB (PC2-4200) + 512 MB (PC2-5300).
    Apple doesn't exactly tout this as a feature, but in my experience it will work. It's not an ideal solution and frankly I wouldn't go out of my way to get PC2-4200. However - I've tried it myself out of curiosity and found that it did work - at least in my machine.

  • 1GB PC2-5300 667MHz DDR2 Does this work on the 867 Mhz Powerbook?

    PNY 1GB PC2-5300 667MHz DDR2 SODIMM
    Does this work on the 12-inch 867 Mhz Powerbook?
    I know for a fact that it can be upgraded to 1 Gigabyte, but I'm not sure of the exact brands/models that are compatible.

    So is the 1 GB PC2700 the highest/newest model that can be used?
    You could install, for example, PC3200 DDR memory, however, the Powerbook will only use it at the PC2700 level. So no advantage there from a performance standpoint.
    I'm not asking if I can go higher than 1 GB. I already know that 1GB is the maximum. I'm asking if there are other 1 GB cards besides the PC2700. Perhaps other cards that are available and compatible.
    I would stick with Crucial, Kingston (not their valueram), or Samsung memory. You have the link to Crucial, and Kingston is at http://www.kingston.com and Samsung is sold through distributors. OWC at http://www.macsales.com is one vendor I've bought from and would recommend. I've used all 3 brands in Powerbooks with no issues.
    Also this is off topic, but where can I find the tool to remove the certain screws near the keyboard and the lower part of the monitor?
    Tools you might be using are a #0 Phillips head (Lowe's $2 with a companion small flathead), a T6 Torx screwdriver (should also be available at Lowe's), a 4mm socket, and possibly a small allen hex wrench.

  • Difference between DDR2 PC2-4300 PA3411S-2M1G and PA3411U-2M1G???

    I understand you that youre a little bit confused but both modules are the same.
    The modules are 1GB PC2-4300 DDR2 533MHz
    I think its only a new release and therefore its a different part number.
    I found out that the PA3411U-2M1G module is compatible and you can use it.

    DDR2 is not compatible with systems designed for DDR memory. It will work for the most recently introduced PB's just a few days ago, that is, if the DDR2 is on a notebook memory stick and speced to work with the Apple PB.
