HP 15-ac070ur memory upgrade

[Sparrow2016]

Hello!

I own a HP 15-ac070ur laptop (15-ac000ur series) with only 2Gb RAM (A-data AO1L16BC2N1-BQHS single sided, 4 chips, DDR3L, 1.35v, 11-11-11-28). I want to upgrade memory.  I want to add 2 (dual channel mode) or 4 gig (single channel mode).

I have found several suitable:

1) Kingston 1.35V PC3L-12800 4GB DDR3L 1600MHz SODIMM Ram Memory KVR16LS11/4 204PIN

2) Kingston HyperX Impact Black 4GB 1600MHz DDR3L CL9 SODIMM 1.35V Laptop Memory (HX316LS9IB/4)  

3) ADATA 4GB 1.35V Low Voltage DDR3L 1600 MHz PC3-12800 RAM (ADDS1600W4G11-8)

4) Samsung M471b5173db0-yk0 4GB DDR3L PC3L-12800 1600MHZ PC3L-12800 DDR3 204Pin laptop memory

5) Hynix  HMT451S6BFR8A-PB 4GB PC3L-12800 DDR3L 1600Mhz 204pin SODIMM Laptop Memory 1.35V

Prompt, please, most compatible options or your variants

Well here is the problem. From the Manual:

One non-customer-accessible/upgradable memory module slot (Intel Pentium and Celeron processors)

So, double issue. 1. Not customer accessible. 2. Only a single slot single slot since you have the Bay Trail Pentium-type processor.

See p. 46 for memory install instructions. You remove the bottom cover first which is a lot of screws, but you do not need to remove the motherboard. This will jeopardize the warranty, but is doable if you are careful. The max memory is 8 gigs and here is the recommended module:

8-GB (PC3L, 12800, 1600-MHz) 693374-005

This module is guaranteed by Kingston to be compatible:

With the Bay Trail processor you really need 8 gigs of RAM, although even 4 would be a major improvement. Dual channel is not possible, obviously.

Thanks for a prompt reply!
I didn't know that I have only 1 memory slot...
I had Intel Pentium 3825U, 1900Mhz, 2 cores.
Broadwell core or Bay Trail? It is possible to mix with old Intel Bay Trail E3825, I have 3825U
It seems that I have Broadwell.

If I haven't mixed, I have "HP Notebook PC" or "HP 250 G4 Notebook PC" series laptop (model P3S41EA)

I used memory search on Kingston site "250 G4 (Pentium/Celeron) Notebook" and the result was: KCP3L16SD8/8 (8Gb) or KCP3L16SS8/4 (4Gb)

I have found them on eBay:

http://www.ebay.com/itm/4-GB-SODIMM-DDR3L-1600-4G-1-35V-KCP3L16SS-4-Apple-iMac-Dell-Compaq-Lenovo-To...

These modules are compatible too?

It is actually Pentium N3825U and it is Broadwell. One of those Kingston chips you link, even though they say for "Mac" will work fine.

Thanks for council!

I have returned to tell (all to whom it is interesting) that I have successfully made an memory upgrade

(HP 15-ac070ur + Kingstone KCP3L16SD8/8 (8Gb) = LOVE, I confirm!)

It was difficult, I have been VERY careful and frightened, but everything has turned out!... AND I have been surprised that there were 2 MEMORY SLOTS !!! Now I have a MONSTER WITH 10GB RAM! 😄
