Howdy Tom's hardware community,
Long time lurker, first time poster. I was wondering if you could help me with some RAM issues for my Acer Aspire V5-573PG laptop. This is also cross-posted with the Acer community forum.
Since the laptop is getting on in years (read: out of warranty) but is otherwise a good work/mild gaming laptop, I decided to boost the RAM from 8GB to 12GB. This model's listed maximum RAM is 12GB: 4GB is soldered to the motherboard and there is one socket with a SK Hynix 4 GB DDR3L 1600MHz stick. It has been upgraded to Windows 10 Home with no other driver or hardware problems.
Originally, I bought an 8GB Crucial DDR3L (1.35 V) 1600 MHz stick. This is the same speed and voltage as the OEM SK Hynix stick that's originally included, and was listed as a compatible part. However, when I installed it, it wasn't recognized by either the BIOS or Windows. After upgrading the BIOS to the latest version and some troubleshooting (cleaning the socket, reseating it about 100 times, making sure maximum memory wasn't enabled in windows, clearing CMOS, etc), I figured the stick was a dud and returned it.
In this process, I also noticed that the RAM slot has "1.5 V" printed on it, so decided to try a slower (1333 MHz Corsair value-ram) 1.5V stick to see if there was a difference, but the same problem occurs. This time, I decided to download CPU-Z and Speccy to generate reports. Interestingly, the RAM is recognized by both programs but isn't seen by the BIOS or Windows. I know both CPU-Z and Speccy just look at the SPD info, but it makes me think that somehow this can be solved!
Important note: the socket isn't dead - I can put the OEM 4GB stick back in, and it's recognized without any issues.
TLDR of things I've tried:
-"Maximum memory" in Windows is not enabled. Yes, it is 64-bit.
-Upgrading the BIOS (current ver: InsydeH20 2.30) to the most recent provided by Acer. Haven't messed around with a hacked BIOS.
-Unlocked the advanced configuration in the BIOS (Fn+Tab method) and spent about two days playing around with chipset/CPU settings. Changing XMP profile settings, memory timings, and base memory frequency don't help.
-The BIOS doesn't seem to have a memory hole remapping option. Maybe it's under another name?
-CMOS has been cleared and BIOS defaults have been reloaded a bunch.
-I've heard things about bent CPU pins/overtightened coolers causing issues, but I think the CPU is soldered to the motherboard anyway.
I've poured over similar "CPU-Z sees my RAM, but Windows doesn't!!!" threads, but to no avail - most are desktop setups where musical-RAM can be played. I only have one slot to work with.
I might be able to borrow another laptop to test the Corsair stick, but don't have that information at the moment. Anybody have any other insight?
