• HP Pavilion dv6 (3040sl) - RAM not detected

  Hello

  I have a problem with my laptop RAM Detection. I had my dv6 for almost 3 years. Never had any problems.

  Recently, I realized the performance became worse and worse and could not understand the reason.

  Almost by chance today I have real system says is have 2 GB of RAM instead of my usual 4 GB (has always been 4 GB).

  Nothing has changed in my pc. No major updates or anything. Does this mean that my RAM is broken? Or can we the mobo RAM slot?

  I opened the pc and the two Rams (2 GB x 2) seems ok for me. Not sure what I should do then.

  Try removing and reinstalling the memory. Also you can do a memory disk (CD or thumb drive) to test and run memtest86 to check and see if one of the modules is bad. You can also replace the modules into the two slots that need to diagnose if one of the slots is bad. If it shows 2 concerts or combining then two modules are good but a slot is bad. In last resort you can try to clean the gold leads modules very gently with a clean cloth and blowing the memory locations to see if, perhaps, dust arrived and does not have a good connection.

• Studio XPS 8100 - (Best Buy Version) bought end of 2010 4 GB DDR3 Ram problems 1333Ghz

  Greetings,

  I bought a Studio XPS 8100 in late 2010 at a Best Buy store. It came with 4 cylinders of 2GB 1066Ghz (each cylinder), adding up to a total of 8GB spread on 4Slots, all of a sudden one of the slot (Slot 2 to be precise) Ram began to fail, so computer would beep to reveal no ram or sometimes ram write failure etc. So, to avoid problems with this slot (Slot 2), I got rid of all four locations of 2 GB and wanted to replace them with the following ram: "(Kingston HyperX FURY 4 GB 1333 MHz DDR3 CL9 DIMM quantité = 2 d'ajouter jusqu'à 8Go en Kit) ', but my computer is beeping not revealing no ram detected." Now, according to the Studio XPS manual, the configuration can be either Ghz 1066 or 1333 Ghz as long ram DDR3 of Ram.

  I would like to know why my new 8 GB kit (2x4gb 1333 Ghz) does not work with my computer Studio XPS 8100? RAM is correctly inserted on the slot 1 and 3 (I even tried different slot combinations).

  It would be a great help if you guys can let me know what DDR3 1333 Ghz Ram is compatible with my Studio XPS 8100.

  Thank you!

  I contact Kingston technical support and get their help.

  I think the chipset on the studio XPS 8100 is H57.

  H57 is not listed as a compatible chipset on the webpage the HyperX fury.

  http://www.Kingston.com/us/HyperX/memory/fury

  Could it be the timing or Sub timings and memory density or...

  Kingston has maybe a different kit that will work and they can exchange.

  or return it and check the crucial.

• Work very well iMac 27 mid-2011 with 4MEM error code

  Hi, I have an iMac 27 inches, mid-2011 with 4 GB installed original (Elpida so-DIMM) so I improve it with 4 new 4 GB Kingston (ram value) KVR1333 PC3-10600 1333 Mhz DDR3 DIMMS for a total of 16 GB, after that my iMac works very well for three years with the daily use of any question and everything seems normal in "about this Mac" and in the "memory" tab no software issues no kernel panic , anything with a strange behavior, until three years after the upgrade memory, now I run AHT because the other reason (I can't work with a new MBP Mid 2012 airdrop both with El Capitan OS X) and it shows me a 64/4MEM/40000000: 0x8893cb98 error code, I reset the NVRAM and SMC, and same result AHT , so use MemTest86 from a V6.3.0 of bootable CD (full test upward at the end time spent 23 hours) and V4.3.7 showing no error in the two tests, also I ran mdsched.exe RAM Memory Sticks Checker windows (I have Windows 7 64 bit family Premium installed in bootcamp) and no ram detected error.

  While I should care that error? should I change my Ram modules?

  Thanks in advance

  You have a faulty memory card or the slot. That's what the error means generally. Make an appointment with the Apple Genius Bar for the service. If you need a Apple Store - find a store - Apple.

• Map search mother Alienware Aurora R1

  I got an Alienware Aurora R1 of the customer who was preparing to throw, as his son is off to College. Unfortunately I could not any background on his current condition.

  So he came without hard drives or memory. I was able to recover 6 2 GB memory cards and place a spare inside sata drive before trying to start it.

  When it turns on I get 3 beeps and a pause and 3 beeps again. He continues to cycle in this model. No video at all on any of the two video cards dual monitor.

  My research indicates the beep code of 3 beeps means it needs a new motherboard.

  I want to just restore this computer and give to some children. Cost isn't a factor.

  Any help would be appreciated.

  Hello

  I bought a new Dell Inspiron 15z touch ultrabook and when I pressed the power button, it starts to beep and won't start. The screen is totally blank. What should do? Help, please

  -Mayur gala

  Hi Mayur,

  Welcome to the community,

  Sound signal can be used as a diagnostic indicator. The computer may emit a series of beeps at startup if errors or problems. This series of beeps identifies a problem and is called "beep code".

  See the table below which shows the beep codes and the possible problem:

  Overview of beep Code
  Beeps	Description	Possible cause
  1	ROM BIOS checksum failure	The map system, covers BIOS corruption or errors ROM failure
  2	No memory (RAM) detected	Memory or memory slot failure
  3	Chipset error (North and South Bridge error) Time-Of-Day Clock test failure Gate A20 failure Super i/o chip failure Keyboard controller failure	System board failure
  4	Memory read / write failure	Memory failure
  5	Real Time Clock (RTC) power failure	CMOS battery failure
  6	Video BIOS	Video/smart card failure
  7	Failure of the CPU	Processor failure
  8	LCD SCREEN	Failure of the LCD

  Let me know if you need assistance.

  Thank you

• RAM is not detected on my Satellite A300-1MC

  Hello

  I bought 4 GB of memory RAM upgrade Pro and it does not seem to detect it on my A300-1MC

  Here is the link for the RAM I got where it is evil, but I doubt it because the part number matches what I need:
  [http://www.memoryupgrade.pro/4gb-toshiba-satellite-a300-st4505-memory-1x-4gb-pa3670u-1m4g-pc2-6400-ddr2-800mhz-so-dimm-upgrade.html]

  Any ideas what I need to do?

  I have a 3 GB already installed and I took out the 1 GB and put 4 GB in its place - the BIOS didn't detect it as I know that 32-bit Windows usually use all the 6 GB.

  Thanks in advance for any help on this.
  If you need more simply make information let me know.

  Thank you
  Keith

  These problems are typical, when someone buys a product or incompatible products name.
  My advice is to return and buy compatible and tested modules of RAM. What you need is 4 GB DDR2 - 800 MHz module, with PA3670U-1M4G part number. It seems that the RAM you bought must be right, but... What is the brand of this module?

  Best brand for the Rams is KINGSTON.
  Check it out on KTT800D2 / 4G.

  Is RAM recognized if you use only this new RAM (slot A)?

  By the way: your Satellite can be improved up to 8 GB of RAM. Cool!!!

• RAM Mac pro 1.1 detects only not all after kernel panic

  Hello

  my mac pro 1.1, 2 x 3.0 Ghz quad core, ram 24 GB os x 1.7.5 just had a kernel panic and stop, after being on for 12 plus hours for most sitting idle. When I restarted the mac pro, now he is grateful only 12 GB of ram on a lift and another elevator shows empty, the DIMMs are installed in mounting a 4gb4gb2gb 2 GB, riser board b = 4gb4gb2gb2gb =, are all matched pairs. all the ram has been installed and functional for the 7-8 months without any problem. This is the first time my mac has never stop from a kernel by itself, panic and he never failed to see half of the ram before, in fact it worked great for quite some time so far. I don't know what is happening and I hope someone can help me get this figured out and find a solution to this problem, thanks in advance.

  You have a RAM failure.

  The Mac Pro features help Error correction Code RAM with hardware integrated with its Xeon processor. The Mac Pro 1.1 uses FBDIMM who get hot and do not have a long life expectancy. Work for 7-8 months does not work tomorrow.

  The error correction is used aggressively at the start, and all DIMM found to have errors during the Power-On Self Test brief execution have their slots declared 'empty '. This isn't an anomaly, these modules DIMM turns out to be BAD.

  If these modules DIMM is stickers from the seller, you can get replaced them under warranty of the seller.

  The kernel panic, you met just might be part of the same problem. You can find the report and review it and post it if you want.

• W510 does not detect 16 GB of RAM

  Hi, I bought Thinkpad W510 a month ago and then I updated memory up to 16 GB. My laptop detects only 8 GB of RAM. I tried to change the RAM, but it detects only the RAM into the slots on the keyboard. It does not detect the RAM which is at the back.

  My Ram is DDR3 - 1333 - PC3 - 10600. I have 4 X 4 gigabits.

  Am I missing something or I have to configure to make it happen?

  Thanks for any help.

  Ok. Fixed.

• I installed 4 GB of RAM in my computer Windows XP which has detected correctly 4096 MB, but the system information that 2 GB of Ram available.

  I recently installed a maximum of 4 GB of RAM for my Win XP Home computer: four tips of 1024Mo in 4 available memory locations. Story: It came with 512 MB of RAM (256 MB two cards to 2 of the 4 slots). I sometimes treat files large image or video in a few applications, and if I do too much without saving the files, I get something like "...". not enough memory to complete... "and can not save either and lose an hour or two of work, all frozen, treatment and once had to turn off the computer by pulling the power plug (nothing else worked). Later, I added two boards of 1024 MB and moved the two 256 MB for the other two locations. The computer has detected correctly the RAM and showed 2,560.00 of available physical memory total MB of RAM in system information and available physical memory 2.00 GB (currently about 550 MB, current process). I put 4 GB page file. That helped a lot with the processing of these applications, but if do not attention, the same "...". not enough memory... "thing and I lost the job. So I added another 2 identical cards of 1 GB replacing the two planks of 256 MB. The 4 GB of RAM, I've added exact IS correct type for my computer. Set the pagefile to 1.5 times RAM available, etc, so that's it of OK. NOW THE PROBLEM, if it'S a PROBLEM: in the information system RAM is detected OK, showing 4,096.00 MB total physical memory, BUT not much more available memory: 2.16 GB available physical memory! Total virtual memory 2.00 GB remains the same in both cases, even if I put the pagefile of 12 GB. Page file space shows what I put in more added about 2 GB.
  SO THE QUESTION: Is all the 4 GB of RAM (essentially) available for use with my operations high megabytes to image and video processing applications?  Or is Win XP steal my RAM and makes the page file? What happens here? You wish to know if I've lost $120,00 on two more strips of 1 GB of memory. Thanks loads, if someone can tell me.
  Did not have a pretty good test in image/video applications to find out if I won anything yet. Always the same 550MO ongoing process. And Yes, I spent hours on the things in forums of online learning on the page file and RAM, most of which I knew already, but there is no explanation on the information system does not more than 2 GB of RAM available.
  Thanks loads, if someone can tell me.

  "My OS is Windows XP family 32-bit." End of the story for the possibility to use up to 4 GB of RAM. No, there is no way to magic, you can force a Windows 32-bit operating system to use all 4 GB of RAM. There is a difference between the question of whether a motherboard will support a certain amount of memory and an operating system be able to access memory. Sorry, you missed this fact in your research. Oh, and if you want to try one of the many Linux distros do not forget to use a 64-bit - after checking your processor is 64-bit also. That yours is not.

• Acer Aspire One AO751h only detect key 2 GB Ram 1 GB

  I recently bought a stick of ram for my AO751h, hoping to get as much life in my old netbook as possible.

  The particular stick of ram that I bought was a Kingston 2 GB PC2-5300 DDR2-667 KVR667D2S0/2 gr.

  I'm running the stock installation of Windows XP Edition family, upgraded to Service Pack 3, and before and after the upgrade, I see still 0.99 GB detected by Windows in system information.

  I ran CPU ID and found similar results.

  I did a little research and found that a BIOS update can cause this problem, so I downloaded the latest version for this laptop specific to Acer and flashed.

  After reboot, the same problem is prescent, and in the BIOS, it detects only 1 GB of ram.

  Is there anything else I can do to get my AO751h to recognize that there is full capacity?

  The RAM stick, that I bought has been renovated and there is a possibility it could be a relabeled 1 GB RAM stick, I don't have any other phones or computers that accept this RAM to test and see if this is the case.

  Anything above the 3204 Bios version to make the visible 2 GB. Unless you have a hardware problem, I suspect memory dimm. Remove the memory and clean the contacts with alcohol and the qtips. Reinstall it and check again.

  Amazon has this new dimm for $14 and free shipping.
