Acer Aspire 5742G with 8GB of RAM fails to boot Windows 10 64-bits

A friend gave me an Acer Aspire 5742G with Core i3 m370 CPU. I replaced the harddisk with a Samsung SSD 850 EVO 250GB. I am having problems with replacement of the 2+1GB DDR3 (1333MHZ) memory with 4+4GB Kingston KVR13S9S8K2/8 (1333Mhz DDR3) memory.

I installed Windows 10 32-bits NL using 2+1GB and installed 4+4GB afterwards, the laptop booted OK, showing 4+4GB but obviously not having 8GB available. Windows memtest ran OK. A Windows 10 64-bits NL install USB hung after displaying the Windows logo, A Kernel Security Check BSOD and eventually the laptop even powered off.

I installed Windows 10 64-bits NL using 2+1GB and installed 4+4GB afterwards. The same thing happened again. I tried using only 1 memory module, switching memory modules and memory slots. Same result.

I have run out of ideas. The only thing I can think of is a faulty MMU. Anyone with other ideas (and hopefully one that solves the problem)?

are you sure that Kingston KVR13S9S8K2/8 (1333Mhz DDR3) have the correct specifications matching the original ram sticks?

MEMORY ELPIDA SO-DIMM DDRIII 1333 4GB

MEMORY SAMSUNG SO-DIMM DDRIII 1333 4GB

M471B5273CH0-CH9 LF 256*8 46NM

those are the official Acer ram sticks.

No, I am not sure. I ran Everest with the original memory, which gave (sorry for some Dutch wording):

Kingston gives:

ValueRAM's KVR13S9S8K2/8 is a kit of two 512M x 64-bit

(4GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), 1Rx8

memory modules, based on eight 512M x 8-bit FBGA compo-

nents per module. Total kit capacity is 8GB. The SPDs are

programmed to JEDEC standard latency DDR3-1333 timing of

9-9-9 at 1.5V. Each 204-pin SODIMM uses gold contact fingers.

The electrical and mechanical specifications are as follows

IronFly

First of all the kingstone timings are higher than the original, i can't find the voltage of the 2 installed modules.

please run CPU-Z

http://download.cpuid.com/cpu-z/cpu-z_1.74-en.zip

and re-check timings and voltage (SPD tab), the new modules must match the original.

REvandenBerg

Please find SPD output below. Voltage is 1.5V

SPD.png

IronFly

ok, CPU-z is reporting the right values.

the kingstone ram seems a perfect match but...since you already tried puttin only on ram stick at once, probably there is some incompatibility.

i would give a look at the supported ram sticks, check if you are able to find it using the codes i posted.

REvandenBerg

@IronFly

Your suggsted supported RAM sticks can be found, but unfortunately only at an unreasonable price. I cannot find a list of Acer's supported RAM. I will try Acer support.
