Occupying second RAM slot leads to computer not booting.HELP

September 2, 2018 at 09:10:22
Specs: Windows 10
Laptop: ASUS F510UA

I'm trying to install a second RAM stick into my laptop however anytime I try to boot with the second RAM stick installed, my screen will be blank/black. I know it has to do with the second RAM slot because I did some test that prove it isn't the RAM stick. Original RAM stick is single rank 8gb, aftermarket ram stick is Crucial dual rank 8gb. Both Crucial and Samsung RAM sticks are DDR4. I'm pretty sure this doesn't matter but I put up the information just incase anyone ask.

Test 1: Slot 1: Samsung RAM(Original RAM Stick) Slot 2: Empty Result: Boots fine. This was how the computer originally came.

Test 2: Slot 1: Samsung RAM Slot 2: Crucial RAM Result: Power button light boots but screen won't turn on.

Test 3: Slot 1: Empty Slot 2: Crucial RAM Result: Power button light boots but screen won't turn on.

Test 4: Slot 1: Empty Slot 2: Samsung RAM Result: Power button light boots but screen won't turn on.

Test 5: Slot 1: Crucial RAM SLot 2: Empty Result: Power button light boots but screen won't turn on.

Test 6: Slot 1 Crucial RAM SLot 2 : Samsung RAM Result: Power button light boots but screen won't turn on.

Because of these test I suspect that it has to do something with the second RAM slot. Is there a settings I have to change in order the be able to access the second RAM slot or do I have to change anything in the software side before I am allowed to use the second RAM slot?

Just did a reset on the bios to default and the screen still wont turn on.
On the crucial website it does pass the compatibility test so I take their word that it should be fine with a different brand in slot one. Also the are both running 2400 hz.

This is my first time trying to upgrade a laptop and I have little to no expreience with these types of things so if there is a solution, please be clear and very thorough with the instructions given. Thank you.

The Picture attached is of the Crucial RAM stick in Slot 1 while the Samsung(Original RAM) sits by Slot 2(Not inserted).

Your tests results show the problem is with the Crucial RAM, not the slot. Test 1 vs Test 5 tell the story. Actually, any test with the Crucial RAM installed fails.

hmm thats quite interesting Im looking at the product number and they dont seem to match even thought this is where I got them from
My prat number is CT8G4SFD824A
but obviously this is different than the one that is listed. I will try to see what I can do to search compatibilities and let you know what I come up with

So the following picture is that of my order that was processed from crucial which is that of one that is listed in the compatibility list. However when I click the link within the order it will redirect me to their site with a RAM with a different product number. It is strange that I cant find my computer on the compatibility list when I get redirected to the crucial site with the CT8G4SFD824A part number. I will place a link to it below. other than that all the specs look the same and it even works with me putting it into the first RAM slot, just having issues with the second slot. Also samsung RAM wont work in the second slot either as stated in the original post.

I will contact crucial and see that they have to say for themselves.

There are more differences in memory stocks than just the DDR4 and the 2400MHz, there is also the other numbers Timings, Latency, etc. as well as voltage. Your computer may be trying to use the settings of one stick to run the other but neither is compatible with the other. At the minimum, you need to make sure that all of the numbers are the same:
The specs I found on a random set online to show you:
16GB (2 x 8G)

Type
260-Pin DDR4 SO-DIMM

Speed
DDR4 2400 (PC4 19200)

CAS Latency
16

Timing
16-16-16-39

Voltage
1.2V

A MUCH better idea would be to get a matched set with two identical sticks in one package.

I understand now what you are saying but in test 4 where I had slot 1 empty and slot 2 with the oem Samsung it still wouldn’t boot. Is this because i have to use the first slot before occupying the second one or should it not matter which slot I use if only having only memory stick?

You may need to go into BIOS set up and set the memory setting manually if only using slot 2, especially if after running the other stick in slot 1 recently.

You can also try cleaning the contacts on the memory stick with a soft clean pencil eraser and then popping it in and out 4 or 5 times to burnish the contacts clean there as well.

Go into BIOS set up and set the RAM settings manually or use the XMP profile setting stored on the memory sticks and see if that helps. If you cannot get into BIOS with both sticks then set it with one stick installed, shut down and add the second one.
If that does not work then you have a compatibility issue with the memory, a bad memory stick, or a bad motherboard memory slot.
You can test the memory one at a time with Memtest86.
You can contact Crucial if one is bad or incompatible.

Clear CMOS anyone(&reset both sticks in the bios to run at 2133MHz or lower with timings like CL15-15-15-36-t2), if even possible on a laptop...

I would agree with #7 the most, return the 2nd stick you have & try to get an identical stick to your original one would be the best.
