Memory speed problems?

don't know if anyone else has experienced this but let me know if you have and if there is a way to fix it. So I am running XP Pro from Boot Camp 1.4. I test my Windows performance with PC Pitstop. When I was running Vista on 1.3 I tested and the memory speed was 8230 MB/s, very good. Now when I running XP with 1.4, my memory speed has dropped to 3300 MB/s. Does anyone know a different speed test for XP.
Also is there a speed test for OS X?
And there seems to be a lag sometimes in response. I will sit down to use XP and it will take a minute of sitting there before I get "dings" and responses to input.
It seems that there might be a problem with the defrag also because even when the drive has just been defraged, it still gives me a defrag warning. Any help on this would be much appreciated.

After looking into this a little more, it seems that the transfer rate I am getting for my memory is consistant with DDR2-3200 RAM which runs at DDR2-400 speeds. Does this mean that the memory is not as fast as it could be. Do they make DDR2-667 modules?

  • Memory speed problem

    Hi guys/gals,
    I received today my memory: 2*512mb mushkins PC3200 400mhz...here is the problem:
    everytime I boot up I receive a post saying: 333mhz. I ran sysmark: 200mhz*2, I ran cpu-z: 200mhz*2 and ran another tool saying I have to ddrs at 200mhz. but whenever I boot I receive the message 333mhz and whenever I run those tools I see detected 333mhz but when looking on them appart: the proggies mention the 200mhz.
    I tried the latencies down to 2.5-3-3 but problem stil remains.
    what can I do, please help!!!

  • Memory speed problems with Neo2 Platinum

    Hi all -- I'm trying to figure out a problem I'm having getting my memory frequency up to speed. Right now I have two 512MB sticks of Crucial Ballistix PC4000 RAM but I can't get them running any faster than 166Mhz each (or 333 Mhz DDR). I'm using a AMD Athlon 64 3500+ processor and I've got my ratio set to "auto." Is there a memory frequency setting I'm missing? How can I get these sticks up to speed?
    Thanks!

    dont worry - i did exactly the same! Not sure if was being a bit slow or the manual is written badly but it confused me  
    Out of curiosity what is core center reporting your cpu temp as? Mine says around 58c but im not sure if its just being reported wrongly ( even though a few people have said this 1.2 bios fixes the temp isssue ).

  • A505 S6033 / Memory Speed Mixing

    Good Day,
    I have a Satellite A505-S6033 i7 720QM @ 1.6GHz Part Number: PSAT9U-006002 OS/Win7 Ultimate HDD/500GB Memory/6GB [Originally 4GB (DDR3-1066/PC3-8500) only].
    I removed one 2GB(DDR3-1066/PC3-8500) memory in the 2nd slot and upgraded the memory with a 4GB(DDR3-1333/PC3-10600) and it is working normally. But I noticed the fan is now running intermittently or continuously even if I am not playing games or using applications with high memory usage.
    Is mixing a higher memory speed going to cause the fan to run intermittently or continuously to prevent overheating, freezing or auto shut down problems?
    Thanks in advance for any advice to my query.

    Been doing some more testing and playing around with the A505 and confirmed that my netbook with an Intel® Atom™ Processor N4501 (1.66GHz, 677MHz FSB, 512KB L2 Cache) responds faster in many situations such as start button load time, explorer populating the folder list and things of the like.
    So i'm confused about the 1.6GHz A505 vs. 1.66GHz netbook. Are they in fact equal for typical tasks? I guess I was expecting something outrageous with the A505 and I too was mistaken by the 2.8GHz in the ad. 
    I have til thurs before my 14 day return is up. Wondering if a faster i3 processor like 2.12GHz would be quicker or an i5 without the turbo boost. I dont game.

  • Memory speed - Equium A200 PSAF5E

    Hi all,
    I own a Toshiba Equium A200 - 1V0
    Model no. PSAF5E - 001003sp
    Bios version updated to v. 2.50
    Everest Ultimate 4.5.1330 says that I have 2GB of RAM, in two sticks of Samsumg DDR2-667. Also it says too that my FSB is 133Mhz with correct CPU speed and multipier.
    The problem comes with memory speed. It shows DDR2-667 capable sticks and chipset, but DRAM:FSB ratio is set to 8:4 resulting in DDR2-533, in any energy profile. The system operates in dual-channel 128bit configuration, so I'm losing 2144 MB/sec of transfer speed.
    The chipset is identified as an Intel Crestline GML GL960, Everest and Toshiba website show it as DDR2-667 capable, Intel website claims about DDR2-533.
    Link:[http://uk.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=UK&com.broadvis ion.session.new=Yes&PRODUCT_ID=138201]
    Link:[http://www.intel.com/products/notebook/chipsets/gl960/gl960-overview.htm]
    I haven't found any motherboard info or manual, so here are my questions:
    - Is this speed normal or may I expect the DDR2-667 mode with this system?
    - Is the dual-channel mode decreasing memory speed?
    - If I re-install memory modules one by one and changing the position, Could it reset the speed values of the system?
    - Can I access to any hidden BIOS settings to tweak the memory? (I have a Medion system that has a hidden and password protected BIOS mode accessible through F11 instead of F2 where I can find lots of options not shown in normal F2 BIOS)
    - Any more ideas?
    Many thanks in advance. Any help would be much apreciated.

    Hi HiperGrover,
    As PauPau wrote, the limited FSB is 533 MHz and that means the memory modules will run at this speed. Furthermore DDR2-667 modules can be used properly but they run only with lower speed.
    So don be worry about this, everything is ok with your notebook.
    Last but not least in BIOS there are no options about tweaking the modules and such options will not bring a strong performance boost but they could make your computer unstable.

  • Memory Speed (MHz) missing in 'About This Mac'

    Hi
    I'm using a Macbook Pro with 10.4.9 and all updates and I recently noticed that the memory speed is missing in the 'About This Mac' window.
    It's saying: Memory 1GB 0 MHz RAM.
    Am I the only one with this problem or is this a bug?

  • Memory Speed Wrong In Cpu-z I have ddr533

    Sorry for the double post didnt mean to do that
    WELL I finally got my better memory to see how far I can push my prescott but only thing is my memory speed is showing up as pc3200 in cpu-z I am running in dual channel and yes I do have one in each slot (1 and 3). Can any one help on this issuse and what setting do I set it to in the bios auto?any help would be great. and what would be good timings for this memory.

    UnderTheSun,
    I can run 3-4-3-7 with SPD set manually with PAT=normal(Disable) and read the same on CPUZ using Bios 3.6, are you always get 3-4-4-8 wiht SPD setting manually?
    I dont have this problem with FSB above 250 mHz (testing with CC I can reach FSB 261 mHz)
    On what FSB did you have CAS set to 2.5 on Bios, since even I set it manually on bios with CAS value 2.5 the CPUZ is always read 3 with PAT=normal(disable).
    Funny thing with this mobo CAS value always set to 2.5 if I turn PAT=Fast (Fast, Turbo and Ultra Turbo always have the same memory speed using memtest86+) and the bad things is I loose the CAS value 3 in Bios so I need to reflash the bios.
    I cannot change the CAS value to 2.5 with this mobo as shown on the following link,
    http://www.anandtech.com/memory/showdoc.html?i=1867
    I would like to try OCZ PC3700 Rev.2 EL Gold Edition which in my opinion working best with this 'P' series regarding DOT and manual OCing as shown in the following link,
    http://www.anandtech.com/memory/showdoc.html?i=1940
    According to OCZ office this DDR is discontinued so I need to find it on the online store and hope can get it.
    So finally I think we need to wait for the newer bios of the 'P' series.

  • Memory speed only showing 200mhz on post

     
    so heres a strange one.  I just moved the guts of my system into a new case this past weekend.  When I booted up for the first time I noticed in post my memory speed is only showing 200mhz.  I have 3 sticks of memory in my system and should run at 333mhz, which it was befor ethe move.  Even mroe curious, I took out one stick and set the remaining two in slots 1/3 and the system only reads it as 333... not 400.  I am a bit perplexed and have no clue how to fix this.  My specs are below.  I know that it is HIGHLY recommended to run chips that are similar but I've never had a problem until I moved the guts to the new case.
    In bios I have memclock set to AUTO.  I have changed the memclock to LIMIT DDR400 but that doens't change anything.  I've tryed changing the CL/TRCD/TRAS/TRP with both LIMIT DDR400 and AUTO....  no changes.  I have upped the voltage all the way to 2.85 with again both memclock settings.  I have played around with my FSB, I've gotten it all the way to 215 without a problem, but memroy always stays at 200mhz.  The only thing I haven't tryed is resetting the bios witht he jumper and starting over (though I had reset bios defualts, rebooted and then made all teh changes again). 
    I ran Memtest for 24 hours on all three sticks and they all came out clean.  I also ran Sandra 2005 and the numbers are embarrassing for the kind of system I have.  I'm stumped, any suggestions?
    OH, one last thing, I booted the system with just one stick of memroy in each slot, thats 9 boots...  each witht he setting of memclock at AUTO and again at LIMIT400...  it either ran at 200mhz or 333mhz on post....
    So there is my ordeal, system is stable but I'd like to get the memmory back up to where it was before the swap.

    Ok...  I shoulld clarify.
    with 3 sticks of DDR3200 sandra ran a little over 1200
    with 2 sticks of DDR3200 (slots 1 and 3) sandra ran a tad over 2108
    there are a couple of pictures eblow to show the post at 15.gig memroy and 1gig.  I am refferin to what is being displayed on POST in regards to the DRAM clock.

  • How do I report a major memory leak problem with Firefox 3.6.10 in WinXP?

    After I installed Firefox 3.6.9 on a WinXP desktop, I occasionally had minor memory leak problems, reflected by getting "out of virtual memory" messages. I upgraded to 3.6.10 when notified that it was available and that it supposedly fixed stability problems. Ever since then, whenever I use Firefox, it starts out quick as a flash, but very rapidly slows down to a crawl, and has twice brought my system to a halt. IE does not cause this, nor any other program I use, but the execution speed of all programs slows as badly as Firefox. If I knew where to get older versions, I would back up to 3.6.9 or earlier. The situation now prevents me from using Firefox much at all.

    Im running windows 7, Firefox 3.6.10 and before i updated to 3.6.10 my CPU never went above 10% with Firefox open. Now it can spike well above 50% and i have nothing different from when i had 3.6.9 to now when i have 3.6.10.
    There is no evidence for me to suggest one of the additions i have is causing it, its all pointing to Firefox itself and the last update.

  • Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

    Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
    This is a NOT an Intel machine. I am running Mac OS X v10.5.8
    Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
    I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.

    http://homepage.mac.com/rep3/filechute/systemProfileREP3-G5dual.pdf
    When did the fan problem start?
    After I replaced the mother board on the computer.
    Why did I replace the mother board?
    Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
    What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
    1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
    2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
    3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
    4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500

    5) zapped the PRAM
    6) followed the SMU reset instructions for
    Power Mac G5 (Late 2004)
    To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
    • Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
    • Remove the power cord from the computer.
    • Wait two minutes.
    • Plug in the power cord.
    • Turn on the computer.
    7) followed the SMU reset instructions:
    Resetting the Cuda/PMU
    How to reset the PMU:
    • If the computer is on, turn it off.
    • Disconnect ALL cables from the computer, including peripherals and power.
    • If possible, move the computer to a place where you are not standing on carpet.
    • Open the case and ground yourself by touching part of the metal frame inside the computer.
    • Find the Cuda or PMU button
    • Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
    • Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
    • If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
    8) ran disk utilities, repaired permissions
    9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
    10) restarted the machine, ..
    11) found a Fan Control System Update - but it did not install when I tryed to install it -
    12) booted from OSX install disk and ran that disk utility
    13) used OnyX to fix disk permissions, clear caches and temp items
    Nope - still have the same high speed fan problem. ... PLEASE HELP!!
    I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.

    The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
    Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

  • P7n Diamond, Corsair TWIN2X4096-8500C5DF, speed problems

    I have been having various problems with both the RAID and memory speeds in this system.  The RAID problems (DEGRADED RAID 5) come and go but my current primary issue is that the system will not run with the memory set at its rated settings:
    1066 MHz
    5-5-5-15
    2.1v
    The best I can get it to clock up to is 1000 MHz at which the system will run for about 5 to 10 minutes before locking up.  I ran memtest for 2 full cycles at this frequency and no problems were detected (i think it was run at 1000 MHz, it's been a while sorry).
    The system is currently running stable at 800 MHz (the speed it sets the memory to on auto).  It will also run stable at various points higher up to the 1000 as I mentioned above but since I have never heard of someone running their system anywhere between 800 and 1066 (unless they were overclocking) I figgured it would be most healthy for my system to run at the 800 and no higher until we can get this figured out.
    I have seen that this board sometimes sets the wrong automatic voltage on some people's 45nm processors.  My x3350 is a 45nm proc but i'm not sure what its voltage is supposed to be, i just left it on automatic... maybe this has something to do with the problem?

    Hey, thanks guys.   Wow it's amazing that nobody had said anything about the 1066 memory to me before (like when i was building the system and throwing together a parts list). 
    The only problem they could find with my config on eggexpert.com was the motherboard...  they said it had problems with the raid but didn't quote or point to any sources so i just did a google search and when i couldn't find anything to back up their problem statement i just blew it off.  Guess it's the last time i'll ever make that mistake.
    Either way though, MSI says it should work fine.  So if it doesn't, shouldn't there be something that could be done?  You would also think that I could find someone out there who's WAY smarter than me who has had this same raid problem and figured it out and gotten it to work.  I'm sure there's plenty of guys out there who are using this board with a raid 5 as well, so maybe i'm just doing something wrong?   I have always had good results with MSI and I really don't think it should have to come down to finding another mobo manufacturer.
    Oh, and for anyone who might suggest rma, it's too late for that.  Believe me, i would if i could. 

  • Mixing Memory Speeds

    Apologies, wrong thread, please ignore.
    Message was edited by: Rhys Bethell

    Hi Rhys,
    i think what you are talking about is mixing memory size, not speed. You can not mix memory speeds, especially in Macs.
    You can mix memory size in most Macs. Very few Macs use memory interleaving that requires exactly the same size memory modules to work best. The iMacs allow mixing size with no impact on performance.
    Go ahead, Crucial is very good with Macs and can be trusted.
    Also very good is Other World Computing (OWC).

    If I install DDR3 in slot 1 and 2 the system will not boot. If I full populate all the memory slots it will not boot
    In both scenario's after the system does not boot and go back to just using slots 1 and 3 the system boot with CMOS checksum error and need to go in to BIOS setup. All the changes need to be made again, saved and exit and it reboots fine.
    I have already attempted to setup the memory speed to 1333 and 1066 with no luck. Any ideas?

  • Memory Upgrade Problem/Slot not Working

    I have an HP Pavilion G7-1260us.  The laptop came with 4 gigs of memory in one module in one slot.  It is upgradeable to 8 gigs, 4 gigs in 2 slots.  I purchased a 4 gig memory module, installed it and it didn't work.  I figured the system wasn't reading this particular brand on memory so I took it back and got a different brand.  The same thing happened.  System didn't recognize the memory so I took out the installed memory, put the new one in and it worked.  I took that out, put the installed memory in the other slot and it didn't work, so now, I'm fairly sure the slot isn't working.  My question is this, if I purchase an 8 gig memory module and install it in the working slot, will that work and will the system show that I have 8 gigs?  Or will this system only recognize 8 gigs if it's 2 4 gigs in each slot?
    Thanks...

       Hp Support Assistant should tell you what you have. Open up the HP Support Assistant and go to General Specifications, read down to slots. If it shows two slots then they are obviously functioning. If not, go to Device Manager to ensure that there is no conflict.
        It is also very-very of the utmost importance that the two memory cards are compatible with themselves and with your system's memory speed.. . . Which is? . . . .It is always best to have matching cards with sychronized speeds from a single vendor.

    If your running Windows 7, Yes, your system will recognize and use the entire eight gigs.

  • Memory speed of fx 5200 cards

    I can't find out detailed spec of MSI's fx 5200 cards:
    - does any of these have 64-bit memory interface (as some 5200 cards do)?
    - what is speed of cpu and memory
    For instance, what's difference between FX5200-TD64 and FX5200-T64? First one has dvi out, cooler fan and larger board, but that's not what interests me - I would like to know differences in cpu and memory speeds.
    Some benchmark numbers would be nice too, at least 3D Mark 2001.

    I'm looking for budget card and I know what I can expect from that. You're right, memory speeds are not crucial here.
    However, some fx 5200 have 64-bit memory interface (I know for some Gainward cards) which makes HUGE difference, even for low budget cards. Difference is something like 3500 vs 7000 points in 3D Mark 2001.
    I would be satisfied with normal 5200 performance (I'm upgrading from MX400), but not with cripled one (64-bit), and I don't know whether FX5200-TD64 and FX5200-T64 have 64 or 128 bit memory bus.
