  My Mac has 4 slots for memory, 2 slots hold 4 GB each.  Can I add a 8 GB memory in each of the empty slots?  I can add memory higher in the empty slots or what I need to keep all memory equals 4 slots 4 GB each?

  It depends on what iMac you have. Some older models may not recognize 8 GB of memory chips.

  You can put 2 x 4 GB DIMMS in the empty slots, this will give you a total of 12 GB. iMacs are very sensitive to the RAM, it is best to buy RAM from reliable sources like Crucial (direct purchase) or OWC OWC RAM

There are 4 slots for RAM.  Going to have a mixed match (two 4 and two 8) in trouble? Or will it improve my speed giving me 24G of RAM?

  It will be fine as long as they are installed in pairs (and, as long as your model can handle 8 GB modules). Just install them in the empty slots. Working with word documents or online will be not much faster - you will notice the difference in speed apps to respond, with graphic design and video editing, etc or game play. The new OS versions like more RAM, so you can not go wrong there.

  FYI, you do not run iOS on an iMac - Please edit your profile to show what OS version you are using. It helps the helpers.

• Lenovo D20 GTX 1080 SC plus Random closures - also, what are these thermal sensors?

  I have a Lenovo D20 workstation, I upgraded my GTX660 to a GTX1080 and started having some weird random offs of the power system.

  I bought the card on October 21 to run Civ 6 better, fine installed map and ran for three days without any problem.

  The third day, the system itself off the power run game. No BSOD, no warning of any kind, just don't click off.

  Done a lot of troubleshooting and seemed to track down for a thermal problem, because once I did a full clean and system fans and back together, everything worked...

  Flash forward another 2 weeks, mid-game Civ 6, stop at random one another down. System still clean as a whistle...

  It's now a battle since to maintain the system for more than a few days sometimes for a few minutes as it will at the same time more and more.  Last hour of Gears of War 4, exactly the same task.  Thinking it is thermal, I upgraded to something bigger heatsinks (fans work normally same towers / etc), system is now 20 degrees cooler and I still get the random low stop...

  Thought that's current partner, if I traded in my PSU I have for my box of spare prod... No effect.

  Thought the card was dead, so I traded in my old GTX660, the system worked flawlessly...  Swapped the D20 1080 another that I have here, and it worked perfectly fine solid launch an automated Civ game 3 days...  Swapped the 1080 in my D20, worked for another 3-4 hours, then click power off.

  I continue to roaming to heat I have some temporary sensors which seem to put the wrong mistakes, I have one that always is at about 128C called "Remote1" 2 other D20, I have here do not have this sensor, I literally stripped everything out of the box and the sensor "remote1" remains.  Where is it?  (see attached photo)

  HW_Monitor shows my CPU nice and cool... SpeedFan shows a CPU @ 31 c and the other at 101 c, the two seem well in HW monitor. Am I an overheating? OR am I not?

  Here is my complete listing of the system:

  D20

  2 x X 5675-3, 06 Ghz

  48 GB DDR3 RAM

  GTX1080 HC 8GB

  LSI/3ware 9650SE RAID card w/5x3TB

  Kingston 240 GB SSD (boot drive)

  I did the following diagnosis:

  Added new radiators - thermal. (Works great with GTX660, not with the 1080).

  Re-sitting all the RAM, I even changed a lot.  Memtest passes.

  I removed the RAID card and associated hard disks. (I thought that's where they get "Remote1".)  It isn't.).

  I tried the two 16 x slots in the system.

  I ran a full stress test using the handbrake and P95 to try to make the system draw as much power as possible to stress the CPU/PSU/MEM, wanted to test the GPU at the same time so I ran a civ 5 automated and civ 6 interactive game. It ran for several hours and clicked itself turned off AFTER I had finished the stress on the CPU... (I killed the brake hand and P95 and just got Civ execution).

  I swapped the power supply with a known good unit.

  I placed the 1080 in a solid known D20 chassis, no problem.

  I checked the mobo for swelling / leaks / breath caps. No there that I can see.

  I ran the sound system high mode and fan speed used same used maximally all fans, always off System... All time seemed cool except "Remote 1". Read local 66 c.

  I changed the bars that I use.

  I changed the wall outlets that I use.

  I entirely cleaned the system and all associated fans.

  I tried ALL video pilots...  I have done so of restorations and clean installs Windows bored me.

  Windows provides no newspaper except to say "power has been removed from the system or the system became unresponsive.

  BIOS is like a power failure and will reboot the system (once I put it to turn on automatically).

  I'm at the point where I'm going to empty the entire chassis and start over again because its so intermittent and so random that I can't pinpoint the problem.  When you look at Speedfan, the a 'CPU' that says its 101 c, when he goes to 110 c, that seems widely when the system will be eager to stop, he stopped at a few times and 115C, but HW_Monitor still reads the CPU is also nice and cool, with cores running between 35-40 degrees Celsius, not anywhere near 100 101 c...

  I spent several hours on it and still can't seem to find answers that are concrete...

  Someone at - it ideas?  Someone has ideas on what/where all these thermal probes are?

  Can someone give me any ideas would be great...

  Hello

  First of all, thank you guys for getting back to me so fast, I know that you guys must be flooded and I really appreciate your support on my aging material.  You are a credit to your teams.

  So I'm in the mode full tinker now, and as I am not under warranty, it is not as if I had nothing to lose = D.

  I think I have tracked down the problem - but I said at least 6 times in the last few weeks.

  The EVGA GTX SC 1080 has a metal radiator that runs the length of the card, these fins are exposed along the law and the length as a vent along all sides of the map, the side exposed to the door frame and the side which is exposed to the motherboard. There are also a few air holes in the top (bottom?) of the map. When the GTX 1080 is seated in the slot 16 first x, all the heat from the back of the card is discharged directly on the North Bridge heat sink.  This seems to be what it heats up a lot, and why the 660 fact ever, the events don't go anywhere near him.   In fact, I removed my GPU right after a stop down and the NB heatsink was hot touch was a 3 degree burn.

  so I tied a 40mm fan on the heatsink to the Northbridge PCI, he turns to 4000-5000 + rpm and managed to cool the heatsink about 30 degrees, it starts as 65 degrees rather than 95 and revolves around 82-85 under a load of game...

  I'll keep you posted on the tests.

• Configuration of memory for PE R510

  Hi, I have a PowerEdge R510 with eight 4 GB DIMMS. I want to add memory in the most cost-effective way possible, but do not understand what I can replace where and have a balanced configuration. Can someone help me with this issue?

  kentravis

  I think that replacing two 4 GBs with 8 GB will be useful enough

  It would be good to know the total amount of memory, you are looking for but 8 x 8 GB (total capacity of 64 GB) sound economic.

  kentravis

  I want to get the most bang for my buck. 16 GB seems a lot cooler by Go, some of the messages that I read, a channel or bank or something may be a different size, or something.

  Modules memory 16 GB cost a bit more but provide room for future memory upgrade. Yes, the R510 server has a single memory enough population guidelines. It consists of 3 channels; CH0, CH1 and CH2. CH0 includes A1 & A4 slots while the channels CH1 and CH2 are respectively for slots A2 & A3. See the following diagram:

  

  By filling out the memory, the memory in each channel has match and being filled in the strict order of the A1 (for 1 DIMM), A2 (when 2 DIMMs are used), A3, and A4. Note that the memory DIMMS on CH0 do not necessarily have to be the same, they may be different capacity with size larger and populous on location A1 module and the other on the A4 slot. The guide of the user for more information: http://downloads.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r510_owner%27s%20manual_en-us.pdf

• Configuration of memory PowerEdge T410

  Hi all

  Let me start by saying our current configuration of memory (Dell PowerEdge T410):

  We have only one processor installed, so we have 4 DIMM for use A1 - A4. Only 3 are currently installed like:

  A3: 4GB 2Rx8 1333

  A2: 4GB 2Rx8 1333

  A1: 4GB 2Rx8 1333

  A4: white

  in its current wording, our server (running sbs2011) is extremely slow, and we traced it to the use of the RAM. That being said, I went to the store in line of Dell and bought 2 8 GB 4Rx8 1066 RAM sticks to use on the server. I thought I'd take a module of 4 GB, so I then total 24GB (2 GB + 2 8 GB 4).

  Read the manual material, I see that mix 2rx8 and 4rx8 is supported as long as the 4rx8 is in the white slot (first location of the channel). I also see that mixture of capacities of ram is supported as long as each channel has a similar configuration. I assumed that this means that each channel had the same capacity. So I thought 8 GB in every channel:

  A3: 8 GB (channel 2)

  A2: 8 GB (channel 1)

  A1: 4 GB (channel 0)

  A4: 4GB (channel 0)

  I placed the DIMMs in this thought of configuration I have all together until I started the server and I get an error of the incompatibility of DIMM and the BIOS indicates memory configuration not supported. However, starting the server in windows and it says 24GO and is normally. What Miss me? Should I be worried? How can I fix?

  Any input would be greatly appreciated. Thank you very much!

  Hello

  It is not optimal because you mix DIMMS in a bank. The system supports memory triple channel. It does this by spreading a Bank of memory on 3 channels. Here is how the banks are set up:

  DIMM 0 - 1,2,3
  DIMM 1-4

  For an optimal configuration of the DIMMS in slots 1,2,3 must be identical. In older systems that do not support memory flexible configuration the DIMMS in slots 2.3 would be disabled. Since this system supports flexible memory configurations, it will allow the DIMM to stay, but gives no optimal error.

  If you mix memory in this system, you can have 1 Unlike DIMM installed for an optimal configuration. The optimal configuration that uses the maximum memory to the DIMM you have available would be:

  8 GB - 1.2
  4 GB - 4

  The best non-optimal configuration would be:

  8 GB - 1.2
  4 GB - 3.4

  This configuration will always give you errors, but it is better than the current configuration.

  APITech

  I also see that mixture of capacities of ram is supported as long as each channel has a similar configuration.

  This does not mean that you must have identical DIMM modules in the channels. It means that channels must be filled even. Here is an example:

  DIMM 0 slots 1,2,3 =
  DIMM 1 slots 4,5,6 =

  Chanel, 0 = 1.4
  Channel 1 = 2.5
  Channel 2 = 3.6

  You have DIMMs of different rank, speed and capacity mixed through the channels, but you can't have different configurations. For example, in this configuration if you filled DIMM slots 1,2 and then the configuration is valid for DIMM 1 would be filling in only one MEMORY card into the Groove 4 (if the system did not require DIMM be installed in pairs) or 2 DIMMS in slots 4.5. You can't fill a DIMM in the slot 6 since the first slot (3) in the channel (2) is not met.

  The population of channel rule means essentially that you can not complete the second slot in a channel if the first place is not filled. In your housing system 1 and 4 are channel 0. All channels have only a single slot assigned to each memory controller. As long as you have one DIMM in slot 1, you can fill the slot 4.

  Memory population rules can be very confusing. If you have any other questions let me know.

  Thank you

• Satellite A100 - how to remove the Memory Stick Pro DUO card slot

  Hey,.

  I really need help with how to remove my Memory Stick Pro DUO card slot.

  The laptop read the stick very well and I can see all the files into it but I can't seem to get out. I tried to push a little to get out, but it does not work and it's also pretty far in so I can't get out.

  Anyone have any ideas?

  Thank you

  Hello

  To my knowledge there is no extra help for Memory Stick Pro DUO removing as on the PCMCIA port.
  You should try to get him out. If you n t manage to pull him out with you fingers, you can use a pair of tweezers.
  But be careful.

• cDaq-9174 shows empty slots

  I recently bought this cDAQ-9174 with 3 modules installed: 9211-9234-9263.

  I have the latest version of Labview 8.6.1 (first quarter 2009) and NOR-DAQmx 9.0.1 drivers provided with the hardware installed in my system.

  When I opened MAX it shows the empty slots.

  How can I solve this problem?

  Hello Sergey,

  I think that the issue has to do with the chassis itself.  Because this is a very annoying problem and is also very rare, I would get your replaced chassis and defective one sent to R & D so that we can understand what is wrong with it.  Can I have your permission to have our Web support team to recover your account email address so that I can contact you directly to get this problem resolved?

  Original title: Lenovo SL500 Windows Vista crashed with STOP error message and won't start

  Hello peoples,
  I just installed an iMicro Bluetooth adapter on my computer, and then I wanted to restart my computer. When I turned it on, loading like regular until right after the Vista loading screen, when the Blue Screen of Death (a blue screen with an error on this subject) flashed for about 1/2 second and then restarted my computer. Then he asked me if I wanted to load startup repair or simply start WIndows normally and I chose to start WIndows normally, but it's the same thing, so when the computer is restarted again, I chose the Startup Repair. He said that if I inserted an external device in my computer for me to remove it. But I had no external devices in my computer at the same time! I already pulled the iMicro adapter! So when my computer restarted again, I pressed the button Lenovo Care and charge of Lenovo Rescue and Recovery 4. (This is where I am now, typing away in the Opera browser.) I tried to find help, but could not find anythign useful so far. I installed for many drivers, updates, patches, etc. But none have anything to remove the blue screen of death. Now, after 7 hours, I really frustrated, and this is my last hope! (I don't want to save my hard drive and reinstall, because I paid more than 250 applications and more than 270 free programs on my computer! Of more, more than 350 iPad apps, of which a few are paid! Oh and 700 iBooks!)
  Help, please! I'm really desperate right now, and any help would be appreciated!
  Thanks in advance!

  PS I run Windows Vista Home Basic SP2 (I think) on a Lenovo ThinkPad SL500 (NOT SL500c!)

  PPS Lenovo all computers have this Lenovo Rescue Recovery 4, which is like an operating system of its own. It has a browser that you can install updates and other things. Right now I use Rescue and Recovery. Thanks again in advance and please answer my question! I had this problem for a week and I'm in school tomorrow! Thanks again!

  EDIT: The error message went like this:

  A problem has been detected and Windows has shut down to prevent damage to your computer.

  If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

  Check for viruses on your computer. Remove the hard drives newly installed on the hard disk controllers. Check your hard drive to ensure that it is configured and completed proeprly. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

  I have a song that is most often improvised, I was told that his cool, however, re-registration is not possible.

  After reading a lot on the mixture, I now hear where the uneducated choice and errors that I made which explains the sound "not as good" that the song is.

  Before I just jump in and try to undo the settings on the tracks (one is DRUMMER) to return to the raw track before effects/eq/compression ect. is is possible to do?  Opens the unfavorable mix, rename it, save it and just go to work and cancel or disable 'things '.

  The basis of the lean mixture comes even to the root where I 'hot' securities, (orange and red)

  I guess by now you understand my question and I am open to a favorable opinion.

  Thanks in advance for your help.

  I read this question so many times and I can't seem to figure out exactly what you're asking.  You just ask if you can go back in your GarageBand project and edit your tracks again?  Of course, you can, why not you?
