Ideapad 520S IKB - how many ram slots and PCIe

Hi,

I have the same problem but a different question. I bout a Lenovo ideapad  520S-14IKB (Type 80X2) Laptop (ideapad) - Type 80X2 - Model 80X2007SRI with 4 Gb RAM and I want to upgrade it. I read that the 4 Gb is soldered on the motherboard and there is only one socket available. I am wondering if I can buy 1 memory with 4 Gb to have 8 in total or if I should buy 8 Gb that would replace the 4 Gb already in use. These are the info returned by Speccy:

JEDEC #12 1200.5 MHz 21.0 17 17 39 55 1.200 V

 

 

I also saw that some identical laptops are available with 1Tb HDD and 128Gb SSD (I think it's PCIe) but I can't find it in the specifications. 

 

My questions are:

1. Do I have 4 Gb soldered and 1 slot which I can fill in with another 4 Gb to have 8 in total or do I have only one slot?

2. If I want to upgrade to a SSD can I buy one on PCI Express and use it along with the HDD or should I buy a regular ssd and replace the HDD?

 

Thank you!

Re: Ideapad 520S IKB - how many ram slots and PCIe

PSREF:

http://psref.lenovo.com/Product/Lenovo_Laptops/ideapad_520S_14

You have 1 SO-Dimm socket. 8GB max. 2400MHZ.  No soldered memory.

 

Storage:

Some: SSD / SATA 6.0Gb/s, 2.5" wide
Some: HDD / SATA 6.0Gb/s, 2.5" wide, 7mm high
Some: M.2 SSD / PCIe 3.0 x 4

 

Someone else could answer your storage question better.  It appears you can ADD a M.2 SSD in the PCIe slot. The HDD/sata could be REPLACED with a SSD/sata.

Hi laurnicolae

 

Greetings.

 

In addition, I was also checking the motherboard for your MTM 80X2007SRI from the parts lookup page.

It appears that no soldered slot there (orange mark) and with one slot available to replace current Ramaxel (part 01AG701) 4GB DDR4 2400 SoDIMM with an 8 GB (unlike Ideapad 520 with soldered ram).

 

Part Number 5B20N78679.jpgPart number 5B20N78679 MB C 80X2 NOK I57200U UMA NFP BL

The yellow spot on the image appears a good slot of M.2 PCIe SSD similar to the Model: 81BL005WSP and other motherboards for 81BL . I cannot vouch if it is active so you may need to physically check it first to test before any purchase. 

 

Here is the hardware manual and service module for additional reference.

 

Hope this helps answer your query.

Update us how it goes.

 

Regards

Re: Ideapad 520S IKB - how many ram slots and PCIe

I understand that maximul frequency would be 2400 but can I put 2133 for example? Is this compatible too? Are there some recommended memories or memories that are working better?

 

Thank you.

Re: Ideapad 520S IKB - how many ram slots and PCIe

Hi laurnicolae,

 

Greetings.

 

I would suggest staying with the 2400 as suggested by the product specification.

 

Recommended RAM : 8GB max / 2400MHz DDR4, one SO-DIMM socket listed in the hardware manual (item 11 page 74). Machine Type: 80X2 from the parts lookup (to check memory on the commodity type would also give you the certified ram to work best on your model.

 

You can expand your search using the part number (for OEM certified ram) or manufacturer number on the description making sure that you have the same specification from other online resellers but always check for  the return option just in case.

 

Regards

Re: Ideapad 520S IKB - how many ram slots and PCIe

I also have a 320-15ikb that i got from Costco,

Mine has 12 gb of ram.  I cracked open the case to see what I could do for upgrades, this is what I found there is a standard laptop dubbe ram slot with 1 chip in it on the top layer, below that is the sdram chip.  There was only 1 pci slot that I could see.  So for your first question, Probably, just make sure you get the right one.   For your second question, I am atucaly looking at putting in a second drive my self for a luinix dual boot.  This can be achieved by getting one of those adapter trays and replacing the cd drive with a sdd/hard drive. So you could do that and move the drives around  / two ssd's or just one ssd.  It all depends on what you use your laptop for.

 

Also to remove the bottom, remove all of the screws, take out the CD drive, under where the CD drive was carefully pop off the bottom, next pop off the bottom going all the way around the PC.  DO NOT pry the computer with a screw driver, just use a plastic prying tool or your hand and remove the bottem cover going all the way around.  When you replace the screws use a dab of blue locktite and tork the screw 1/2 a turn when the screw toches the plastic.  That whould be the best way to see what is inside.  There are also upgrade guides on the internet too.

Re: Ideapad 520S IKB - how many ram slots and PCIe

Thank you very much! I ended up buying 8Gb Sincron RAM 2400 Mhz and it works good, the only mention is that it works at 2133Mhz, not 2400. I don't know why Lenovo recommends 2400 when it works at a lower frequency. If I had knew I would have bought 2133 with lower latency.
