• Sizes of mixed memory in Dell R710 to reach speeds of 1333 mhz and 800 mhz

  We have some Dell R710 which was originally ordered with 48 GB in a configuration of 1333 mhz 12x4Go (RDIMMS). We ordered 6 sticks of memory of 4 GB 1333 mhz additional to complete all 18 banks for a total of 72 GB.  The speed of the memory, then decreased to running at 800 mhz.  We had immediately complaints on the performance in some of our mission critical VM (terminal Server and SQL DBs servers), so we have VMotion their due on a R710 still on the original 12x4Go config clocked at 1333 mhz and complaints went.  I spoke with pre-sales both Dell and after-sales technical support and they confirm that filling all 18 banks decreases speed to 800 mhz, but I get conflicting reports which must be running 12 banks (which is configured as 2 of the 3 banks available in each 6 channels) at 1 066 mhz now which is not. Still, both say that my best option is to return the modules to 4 GB bought recently and also pull the original 12x4Go modules and replace them all by 12x8Go 96GB and should operate at 1333 mhz.  It is really more memory I need and almost three times that I have already budgeted and spent on extra 4 GB of purchase sticks.

  The other option, you said I could do, as well as that of my question is to mix 6x4Go and 6X8Go, up to 72 GB.  I see also that is a configuration of memory available on the Dell Web site during the construction a R710, and he said 1333 mhz as well.  Technical support before and after had these things to say, and it makes me a little nervous because this isn't an absolute 'you'll be fine:

  prior support guy:

  "Everything I read or say confirms that it is perfectly fine to mix the modules in sizes too long as modules within each channel are the same size." I think it can be recommended by most to ensure the consistency of the size but as I said before that we have in our new server system configurations to be cited with mixed sizes what makes me even more confident that is you went this route you would be fine and little or no experience in performance decline. »

  support after guy:

  "Regarding your new question on the use of 6 DIMM 4 GB mixed with 8 GB for a total of 72 GB, which is not an optimum configuration, but I don't think you should really meet a lot of problems with it."  I mentioned before that if you mix speeds, it will downclock fastest at the speed of slow DIMM DIMMS, so certainly would advise against mixing speeds. Regarding the size, the only thing you might encounter as it is booting, you can hear this isn't an optimal configuration, but it should detect any memory and be able to make use of this.  Don't think there is really a performance reached unless you're missing speeds.  «Also, don't forget to reflect your configuration across all channels, if you do not want all of the 4 GB and 8 GB in the same configuration such that put all 8 GB in slots 1/2/3, then put the 4 GB DIMMs in 4/5/6 on both machines slot A and B.»

  So the real question is - if it is not a "optimal" configuration, which makes it means the actual performance of my vSphere servers?  All done and they have problems?

  Thank you

  How about using 8x8GB sticks for each host? You'd get to 64 GB each... I'd like to see if Dell will allow you to trade in the memory, you do not have to purchase new memory inside the host... Or look for another provider of memory which will provide you with the correct memory at a better price.

  Currently RAM pc3-10600 1333 mhz 4 gb (2 X 2 GB) outside the EEC.

  Thank you

  Hello:

  Installation memory PC3-1600 does not accelerate memory, being the fastest, it can be run to 1066 MHz.

  Even the 1333 MHz memory only runs at 1066 MHz, which is the highest speed of the processor.

  I can tell you that memory installation in any PC HP that has a series 5 including your Intel chipset (and uses the memory of the laptop) is very difficult to upgrade.

  I suggest that you read this post and one that I've referenced in this post to make sure that you get good memory or it won't work.

• NB550D-10U - upgrading memory 1333 MHz? C-60 processor

  I recently bought the NB550D-10U model that has the processor AMD C-60 inside. I read most of the messages on this forum about memory upgrades and they suggest all requiring RAM DDR3 1066 MHz (PC3-8500).

  I guess it is for models with a C-50 processor that I open my netbook and it came installed with 1 GB Samsung DDR3 1333 MHz (PC3-10600) 204pin (part No.: M471B2873FHS-CH9).

  So, I guess I could buy a 4 GB of DDR3 1333 MHz Ram that should work in this version of the netbook. Of course, I will modernize windows for hosting get fully use the 4 GB of ram.

  Has anyone got this version of the laptop and upgraded? Or can confirm that it is the 1333 MHz memory for and * NOT * 1066 MHz as most of the other posts on the forum.

  Thank you

  Theoretically, you can use two types of modules: 1066 Mhz and 1333 Mhz

  1 GB DDR3-1066 PA3675U-1M1G
  2 GB OF DDR3-1066 PA3676U-1M2G
  2 GB DDR3 - 1333 PA3918U-1M2G

  But the laptop does support max 2 GB RAM

• Qosmio X 770-00 X - 16 GB (2x8gb 1333 MHz Kit) SODIMM upgrade - it works!

  This isn't a question, but the answer to a question that I couldn't find the answer to. I went to the computer just today and have to try before you buy a 16 GB Kit of SODIMM DDR3 1333 MHz memory today. It works beautifully.

  After exhausting the internet looking for someone who had done that, I'm happy to say that I'm probably the first to publish the success. I hope that others can learn from this and so successful.

  The SODIMM is memory Corsair CMSO8GX3M1A1333C9

  Next week I'll try the 8 GB (2x4gb) Kit of Kingston HyperX 1866 MHz C11 memory and see what kind of performance increases can be made.

  Thank you very much for your report. Please post the result with the Kingston modules.

• Fix for 580 1333 or 1067 MHz memory speed?

  I plan on adding memory to my six year old, Inspiron 580 for a few years of life out of it.

  When I enter my service tag and run the parts finder, Dell suggest adding DDR3 SDRAM - DIMM 240 pin, 1333 MHz (PC3-10600).  However, when I ran the Dell system detects, it says my memory is DDR3-SDRAM (1067 MHz)?

  In addition, said Dell web site my my service tag-based maximum configuration is 8 GB but the documentation with my 580 says 16 GB.  Because I am running Win 7 64 bit, I guess that 16 is correct as it is in agreement with Microsoft on Win7 64 bit OS.

  In a related question, can I add a 4 GB DIMMS with the other three 2 GB DIMMs (10 GB in total) or do I need to use a 4 x 2 + 2 x 2 configuration (12 GB total).

  Thank you

  The specs say that you can use either 1066 MHz or 1333 MHz RAM.

  Crucial recommend actually 1600 MHz RAM for this model. And the good thing is that they guarantee it works or they take it back.

  Don't forget that if you mix RAM with different speeds, all of it will run at the slowerspeed. Thus 1333 and 1600 MHz RAM can operate at 1066 if you leave the old 1066 RAM installed

  What about the max RAM, card of the Dell for the 580 say:

  Accessible DDR3 DIMM Sockets internal memory four connector

  Capacity of 1 GB, 2 GB and 4 GB memory module

  Type of memory DDR3 1066 MHz or 1333 MHz DIMM; memory non - ECC only

  Support for configurations of memory: 4 GB, 6 GB, and 8 GB

  Win 7 64 bit can handle 16 GB of RAM, that does not mean that your hardware is supported by that much. The amount of RAM supported depends on the BIOS and the Intel chipset on the motherboard.

  There is a demand in this thread that someone installed successfully 16 GB in the 580, but there is no way to verify that.

• HP ENVY Sleekbook 6-1110us: Memory Upgrade - vs 1333 MHz 1600 MHz

  Hello

  I plan to upgrade RAM my laptop 4GB to 16GB (2 x 8 GB). I went through the manual and noticed that the laptop comes with two slots for memory module:

  i. support of DDR3 - 1600 MHz single channel

  II support. DDR3 - 1333 MHz single channel (DDR3-1600 downgrade to 1333)

  I understand that memory cards should "mirror" each other in order to maintain the balance of system, they must be identical in terms of memory and performance.

  My question is this:

  Should a. I buy 2 memory cards that run at 1600 MHz? I understand the second module slot, which runs at 1333 MHz, to downgrade the two cards to this specification. Or,

  Should b. I buy 2 memory cards that run at 1333 MHz? Which would be compatible with the first slot which will at1600MHz?

  Thanks in advance for your help. Impatience on your part.

• B200 M3 memory stuck at 1333 MHz in performance mode

  Hello

  We have 2 B200 M3s in a new deployment running 2.0(3a). The B200s are configured with 64 GB using DIMMs of 8 GB, using BANK 0 of each channel. We deployed a policy of BIOS specifying performance for LV DDR mode and confirmed this setting takes effect in the BIOS, but the memory continues to run at 1333 MHz. When we look at the inventory server, the DIMMs are reported as 8GB 1600 MHz DIMM dual rank. We tried forcing the DIMMs in mode low voltage and return to the mode of performance without result.

  In other UCS environments, we have deployed these same blades with the same configuration of the memory and BIOS policy and had no problem getting the RAM at full speed. We do not use any kind of power is corking.

  Thoughts?

  Hi Brad,

  What is CPU?  support for the B200-M3 CPU 3 do not support the 1600 Mhz:

  Hello

  My card mother H-IG41uATX HP works @ 1066 Mhz with single 2GB 1333 Mhz RAM (Apacer PC-10600) @ 7-7-7-20.

  BIOS is Version 6.08, 07/07/2011.

  BIOS it detected as PC-8500. CPUZ shows like PC-10700 work clocked at 533 Mhz (= 1066 MHz DDR).

  The processor is Intel Pentium Core 2 Duo E 8400 3.06 GHz with FSB 1333 MHz.

  WIndows 7 operating system

  1. Why does is not able 1333 Mhz motherboard @ full speed?

  2 working memory @ 1066 MHz @ 7-7-7-20 VS memory work @ 1333 MHz @ 9-9-9-24, which is better?

  Khelifi

  Sure... While theoretically fastest speed of memory should be faster, there is little or no difference in the overall performance of the memory. The memory CASE latency generally increases the rated speed increases. Latency means basically 'backwardness' and this latency to counterbalance the gain by increasing the speed. Still, you would never notice a difference between the two.

  As a general rule, long term, its not recommended to mix different frequencies & CASE, RAM together.

  But if you ask if they work together at all, they will all be two race to lower speed - no problem whatsoever in this area.

  Fortunately, your system manual lists the frequencies 1600 times & 1333 & if you put two Rams they will work in single channel type - no dual channel supports listed in the guide.  Here is your Manual (Page 1).

  The performance issue that could have landed because they are different, it's that they are running in single channel which is slower mode. But your system do not already support channel.

  So all of your ram is now 1333 but it will work very well in single channel mode.

  Download CPU - Z to see what makes your ram and ram it is. The part listed for 4 GB of RAM is in your manual.

• B200 M2 - 1333 MHz supported with two modules DIMM per channel?

  Review of the 5500 to 5600 processor series Intel framework was for the maintenance of speed of the memory at 1333 MHz (for processors that support) with two DIMMs per channel. Will be a B200 M2 with x56xx processors run at 1333 MHz with two DIMMs per channel memory?

  Thank you

  Jeff

  The above answer is Incorrect.  You CAN fill (2) modules DIMM per channel on the B200 M2 and the memory will be at 1333 Mhz clock (assuming that you use rated 1333 Mhz DIMMS - DIMMs 8 GB or smaller).  Therefore, up to 96 GB running at 1333 Mhz.

  See you soon,.

  Safari maxes in a version of Mac OS x.  New version of Mac OS x would be needed for the new version of Safari.

  Firefox is not limited within an OSX and probably has a version that works.  Chrome may as well but is a Devourer of resources.  Opera is a third option.
