g510 ram upgrade

hey,

 

I have the g510 with 4GB ram (1 SLOT) and I want to upgrade to 8 or 12 GB of ram,

this is what i have now:

http://www.electrobyt.com/index.php?main_page=product_info&products_id=6442#.Vlz78PmrTIU

 

my questions:

- which information I need to check before choosing which ram to buy?

- this card of ram can be compatible?

http://www.kingston.com/us/memory/search/?partid=kvr16ls11/8

it can reduce the perfomance because it different card and company? 

 

oh and what is the 1Rx8 and 2Rx8, is it matter? 

 

 

thanks!

Re: g510 ram upgrade

hi dvir1245,

 

Welcome to the Forums.

 

Regarding your questions:

1. The information that you need in choosing which RAM to buy are the following:

 

Speed: DDR3-1600

    - this is the maximum clock speed that the memory chips support.

    - It's ideal that you buy a RAM that have identical speed as it will run on the slowest speed if the RAM are not identical.

    - More info: Memory speeds and compatability 

 

Voltage: 1.35V

    - refers to the power consumed by a memory module (mainly for power saving)

    - the G510 supports low voltage (DDR3L) so it's ideal that you stick with this type for best compatibility

    - More info: 1.35v - 1.5v Dual-Voltage DDR3 memory

 

Timing: CL11 (11-11-11)

    - CAS Latency (or CL or “access time”) that tells us how many clock cycles the memory module will delay in returning data requested by the CPU (the lower the better).

    - It's ideal that you buy a RAM that have identical timings to reduce delay

    - More more info: Understanding RAM Timings

 

Buffering: None, Unbuffered

    - a specification that makes the RAM more stable by having a register between the DRAM modules and the system's memory controller

    - usually applied in servers so you would need an unbiuffered RAM

 

Error Detection: Non-ECC

    - Error-correcting code memory usually used where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.

    - the G510 supports Non-ECC RAM so it's ideal that you choose this type as an ECC RAM will not work if the unit doesn't support it.

 

2. The kingston RAM that you linked matches the Samsung RAM that's already installed so this RAM is compatible and should work fine on the G510.

 

3. The performance varies on the type of RAM that you purchase.

 

i.e., If you have a Samsung 4GB DDR3L-1600 on Slot 1 and you have a Kingston 4GB DDR3L-1333 on Slot 2, the memory controller will run the RAM on the slowest speed (1333 MT/s) to ensure compatibility. The performance penalty isn't that much in real world usage but you will notice this when you run benchmark tests.

 

4. The "R" on the 1Rx8 and 2Rx8 is called Rank.

 

From this article:

The term “rank” simply refers to a 64-bit chunk of data.  In its simplest form, a DIMM with DRAM chips on just one side would contain a single 64-bit chunk of data and would be called a single- rank (1R) module.  DIMMs with chips on both sides often contain at least two 64-bit chunks of data and are referred to as dual-rank (2R) modules

 

So to sum it up, choosing the same speed, voltage, timing is essential to for best compatibility and performance. Two identical RAM (same brand or not) also works (even in dual channel).

This week i noticed the my windows get blue screen after while regardless I am not using the laptop or during copy files via wireless or by cable between my lenovo tab 2 a7 30hc and the lenovo laptop g510 . 

Is this memory issue ? My memory module Ramaxel 4gb rmt3170ef68f9w-1600

Hi ADIMIAN!

 

Welcome to the Community Forums.

 

Blue screens or BSODs usually appear when there is a critical error or if the system reaches where it can no longer operate safely. This could be caused by a program, software, hardware component, etc. We can determine what's causing it if you can provide us the exact BSOD error message. You can download WhoCrashed or BluescreenView for detailed description of the error. 

 

Regards,
