Need buying advice - DDR3 1600 RAM or a faster speed?

Hey all,.

My old rig is dying so I need to upgrade.

MY PLAN-

I intend to buy a mobo ASUS or Gigabyte Z87 affordable and installing an i5-4570 (or perhaps something better according to the Intel Haswell update in a few weeks). In addition, this platform will have a SSD boot and a second 250 GB SSD for programs. This PC is running Windows 7 Pro 64 bit.

MY USE-

This platform plays several roles. Daily use PC for work at home. I do also some videos of basic editing from time to time. I also use VMWARE WORKSTATION to the implementation of the laboratories in the network of small size and test scenarios. Finally, I'll create a VM in Windows 7 only for day Forex trading - VMWARE is perfect because it gives me snapshots and allows easy back to the top of the entire virtual machine in the case where something goes kablooey! Overall, my typical daily use will be general works of PC (emails, web browsing, Office 2013, etc.) and a commercial VM at the same time.

Question #1-

Strictly from a perspective of VM Workstation - will I benefit from something faster than the DDR3 1600 MHz RAM?

Z87 line memory can OCing. Right now my game rig works 16 GB to 2133 MHz and everything is smooth like butter. At the present time, other than a kind of promotion of sale savage/refund that 8 GB of 1600 is only around $65-70 but 2133 or 2400 is only about $25 more. But if anything faster than 1600 MHz is overkill, so I'd rather spend the $ extra and get the 16 GB of RAM instead of 8 GB.

I always have a hard time finding benchmarks of VMware. I hear the most common reason is that VMware does not publicly display (maybe it's in the team of specialists, too, but I always just brilliant on it). They seem to also go out of their way to communicate with blogs and sites of news that they are not allowed to display the marks of their products. At least it's what publishers. I do not have my own tech blog.

Regarding the actual numbers on the impact of the memory speed (latency should also be considered too) for applications in general, you could look for benchmarks by AnandTech and Phoronix. In general, the GPU intensive tasks on systems with graphics processors that use main system memory, as GPU from Intel and AMD APU (GPU integrated into the AMD APU are speed memory more limited than those of Intel), are those who get the most. CPU related tasks don't get affected much or at all. Tasks that are not intensive CPU and GPU is significantly more effective with a faster memory since their active times are so short that ups of speed are not very large in comparison with the total time of the assets (ie. 2 x speed upward on a frequent in 1 second task is not really significantly by most people).

It does not appear that you will be playing games and virtual GPU for virtual machines may be the factor limiting more than the speed of the memory. I don't know what kind of speculation, but the speed and latency would be probably more important for those who make transactions to high frequency where the latencies between trades are calculated in milliseconds.

Here are a few recent memory scaling of items:

http://www.AnandTech.com/show/7364/memory-scaling-on-HASWELL

[Phoronix] DDR3 memory scaling of Performance with AMD Athlon 5350

The AnandTech article talking about avoiding memory DDR3-1600 for competitive amateur and overlockers but the actual numbers reveals almost 0 improvement on CPU tasks and room for improvement of 5% on GPU tasks running on Intel GPU. Not really noticeable.

Phoronix article also shows the differences of negligible performance with the tasks from the CPU. For the AMD APU, GPU intensive tasks significantly benefit from faster memory. These numbers GPU may or may not translate to virtual machines.

  • I have a Macbook Pro mid 2012 edition, i7 and 8 GB (2 x 4 GB) of RAM DDR3 (1600 MHz). Can I add any RAM with this config?

    I want to upgrade my RAM 16 GB (2x8GB) and also to change the hard drive (750 GB) to a 250 GB SSD. I was going through the forum and people have posted that they have improved their RAM with no problems. I visited the local electronics market and is the knowledge that they have a Kingston 8 GB DDR3 1600 MHz RAM. I just want to know if it is safe to add that RAM for my MBP or not? One of my friends told me that the MBP requires a different sort of RAM so I am confused. In addition, I was intending to buy a single 8 GB and set up my MBP with 12 GB (8 + 4) RAM and then replace the other 4 GB with an 8 GB to make eventually 16GB. Will there be a problem with this approach? Also can I add any SSD fits laptops from my system? I found an SSD 240 GB (uv300) Kingston. Please suggest if I can add that.

    You can fit a maximum of 16 GB, if you choose compatible Ram.

    You can upgrade the RAM, but 16 GB ddr3 1600 Mhz is NOT designed for your iMac. Please use the RAM specifications correct, iMacs are extremely sensitive to the RAM and require the correct specifications and high quality RAM. Advanced users on these forums tend to recommend Crucial (buy directly from them) or if you are in the USA, RAM from OWC (www.macsales.com).

    Do not buy RAM in your store, the local computer or cheap RAM at best, it's probably a waste of time and at worst it will simply not work.

    HP uses ram from different manufacturers, depends on which it can provide at any time, it isn't the brand but the specs that matter.

    I would call Kingston or Crucial on the phone for help on the selection, as they ensure the compatibility.

    I have a 700-056 want 64-bit running windows 8.1. After removing the original ram and substituting 16 GB PNY XLR8 DDR3 1600 2 x 8 GB PC3 - 12800 Non - ECC 240 p, machine does not start. Two attempts resulted in empty screens. When finally got error message, it was something about "invalid signature" or such nonsense no layman could never understand. This memory is supposed to be compatible with this machine. What new memory is deleted and reinstalled old memory, the machine functions normally. That is what it is?

    Hello

    First try and boot from the new RAM module 1 stick and see if it boots, if not then try the same procedure with the key, you don't try and see if it boots. Could be a faulty stick of RAM and if so, you will need to send it to the supplier.

  • Upgrade of RAM for Studio 1557 up to 8 GB DDR3 1600 MHz

    Hello

    I bought 2 pieces of RAM Kingston 4 GB DDR3 1600 MHz memory and I assmbled in my Dell Studio 1557. However, when I type F2 and verify installation, we show that the speed of the memory is 1333 MHz!

    How can I gain speed 1600 MHz memory RAM that I bought and installed on my Dell Studio 1557. I use my laptop computer for purposes of design using AutoCAD and 3D MAX and it is really necessary for me to use the speed of RAM 1600 MHz or higher.

    My BIOS version is A09.

    Kind regards

    Correction, which affects the rest:

    The system has two memory - not four.

    You can replace one with a 4G and have six or the two with a pair of 4G to 8 total.

    You must also have a 64-bit operating system or memory beyond 4 g may not be recognized.

  • Unique blend of 8G Single Channel DDR3 1600 with 4 GB Dual Channel DDR3 130

    Just bought a new set of 5000 Dell Inspiron with 8 GB of Ram DDR3 1600 mhz the single channel.  I use Coreldraw and Adobe Photoshop.  Should I spend my modules 4 GB Dual Channel DDR3 1333 mhz from my old Dell 1700 Inspirone series

    The new system uses DDR3L - all phones basic Haswell do.

    Definitely worth not RAM mixture - if it came with a module of 8G and you need more RAM, buy another module of DDR3L-1600 pair with the existing 8 G.

  • DDR3 1600 means windows 7 64 ult won't boot value

    Hello... I just did a reconstruction and I have problems to start windows when configuring memory at 1600 mhz in bios.

    Here's what I bought

    i5 4670 K

    ASUS B85M-E
    Blu Kingston 16GB (2x8GB)
    KHX16C10B1K2/16 X - 16 GB (8 GB 1 G x 64 bit x 2 pcs.) - DDR3 - 1600 CL10 240 - Pin DIMM Kit
    CoreXstream OCZ 500W PSU
    SANDISK Ultra 128GB SSD more

    Also runs a Gainward GTX 550ti, a M - AUDIO Delta 10/10 LT and a hard disk of 1 TB with a Pioneer DVD RW

    Now, in shopping for this reconstruction, I noticed some criticism of memory problems, but not how to solve this problem, other than to change the settings in the bios. I just read on times and tensions, but I'm not sure if and what is true for my scenario and even if I came on my own this far I'm a little lost with playing with the parameters of memory never had to do before.

    By default the memory appears in the bios as 1333 mhz although I don't know why, if there is a problem with the memory or just how the M/B is set at the factory. As it is, my pc works perfectly fast but I would like that you wait, get the full potential that I made the effort to buy memory 1600.

    I don't know if I need to add additional info, but if necessary, let me know.

    Thank you

    1600 means generally that you have XMP enabled in the BIOS. Disable the XMP and then run Memtest86 +.

    Memtest runs from a floppy disk or CD and should eliminate or confirm if one or more of your sticks of memory are bad or the values of the SPD in the BIOS are correct.
    Let it run for as long as you can: 2,4,6,8 or several hours (at least 3 full passes), so no errors at that time then your ram is OK.

  • Profile of Alienware Area - 51 ALX Intel XMP A10 does not work with DDR3 1600 MHz

    I bought three Kingston 8 GB RAM DDR3 1600 MHz 240 pin DIMM that totals up to 24 GB of RAM and install in my desktop computer. When I turned on and the message appeared saying:

    Maternal health and infant is running with DDR3 - 1333 MHz

    WARNING! Previous overclocking failed, and system restore its default value. Press F1 to continue, F2 to enter Setup Menu

    When I access the BIOS setting (version A10), I disabled XMP and then it went through fine after the reboot. However, I have to have XMP allow at any time? How can configure profile 1333 MHz to 1600 MHz XMP?

    What bothers me is that I had three former PIN of Kingston 4 GB RAM DDR3 1600 MHz 240 DIMM which total up to 12 GB of RAM and the XMP worked very well with them before they were 1600 MHz.

    The type of computer I have is:

    Alienware Area-51 ALX

    Intel Core i7 980 Extreme 6 c with 12 MB of Cache

    Windows 7 Ultimate

    Please, help me to solve this problem. Thank you.

    And I certainly don't have the answer, but I'll remember these points:

    1. I think that you can set manually nothing XMP adjustable (but with more control).

    2 machines often memory need to be slowed down when you are near maximum capacity look maintenance manuals.

    3 area-51 has never been tested or even allow the 8 GB DIMMs. You are in the new territories.

    4. If you really need 24 GB (and it works at 1333) then the 267 speed drop is insignificant.

  • I7 950 and DDR3 1600 memory

    I plan a system around an i7 950 CPU, and based on advice from this forum, I want to use 3 x 4 GB memory to make room for a future upgrade to 24 GB.  Most of the 4GB memory in my area is DDR3 1600, rather than 1333.  I may or may not overclock (never done before) - this memory can be used on an X 58 mobo without overclocking?   If you have to overclock to use this memory, the standard Intel heatsink can handle the heat?

    Thank you

    Processor clock speed and clock speed of memory can be defined independently of the other, which means that you can run the CPU at stock speed, but run at a different clock speed memory. You define which in the BIOS of your motherboard. If you only overclock the memory (which is to use the full rated speed instead of the standard speed of 1066 or whatever it is the chipset) your CPU does not work to higher time so cooler stock is OK, but it is nevertheless advisable to use a third party cooler due to the better cooling and less noise. The RAM was designed to operate at speeds greater than the X 58 or other chipsets give you standard, so there is no additional cooling required.
