Installed 8gb ram but only 4gb showing up in system config

xplizitraw · Jan 2, 2018

So I recently upgraded my motherboard to an Asus Z270H, my CPU to a i5-7600K and my ram to 2x4gb 2666mhz ballisticX ram. When I go into my system config to check my CPU, RAM etc it shows that I only have 4gb of RAM available to use. Please help, I tried to change slots, made sure that all the RAM was sitting in properly but it still does not work.. Please help!

Specs:

MB: Asus Strix Z270H Gaming
GPU: Asus Strix 960 4gb
RAM: 2x4GB 2600Mhz BallisticX
Cooler Master Hyper 212 CPU Fan
2x Corsair HD120 LED Fans connected to a corsair fan hub

How much memory does your BIOS recognize? 32-bit or 64-bit Windows installed?

Ok, try to use one stick of RAM (that you know that works) in the slot the "bad" one isn't working. This will test to see if that slot is just bad or not. if it does work then there could be a problem with the "bad" RAM then. make sure you press the ram all the way down in their slots. Keep testing out the Ram to figure out if they are bad or not.

If you upgraded the mobo and cpu did you do a clean install? If it's different to what you had

The thing is, I don't know which slot is the "bad" one.

BIOS? I have 64x windows installed, although after I installed my new motherboard it said that I had to "get a legitimate copy of windows 10" can that be a part of the issue?

It sounds like youre using a hdd with an OS on it from something else. If you are, do a clean install of windows

keatingscool · Jan 2, 2018

Just test out each slot. pick a random stick, take the other one out and put that one stick in one slot. Turn on PC, make sure it reads it. turn off pc and try different slot. Do this with the other stick of RAM as well.

Paul NZ :

How come? I'm using the same OS & HDD as I was before, I don't own an SSD so that can't be the problem either. And sometimes my computer behaves strangely, Like when I tried switching RAM slots and booting up my PC. It wouldn't boot

Paul NZ · Jan 2, 2018

But did you install windows on this new system??

If you didnt, do a clean install. If the hdd was in another system (not this one) then you'll have more probs later.

If you dont do a clean install

You really need to do a clean installation of Windows when you switch motherboards. The chipset drivers for your old motherboard are imbedded into your operating system. After doing a clean installation of Windows, then load the chipset drivers from the CD-rom that came with your motherboard, or download them from the motherboard's website.

The HDD has always been in this system

This is going in circles. First, power the system completely down and disconnect the power cable. Make sure both memory modules are fully inserted into the slots. One confirmed, reconnect the power cable and power on.

Press F2 or DEL to access your BIOS. There you can see how much memory the motherboard recognizes.

What are the results?

By the way, you need to get a legit Windows license it seems.

But you changed the mobo and CPU which are NEW

If you upgraded the mobo and CPU then what was the hdd connected to before?

If it wasnt connected to this system (you pulled it out of the old system - and you didnt install windows on the hdd, while it was connected to this system), then you should do a clean install

The hdd isnt the prob. It's whether you did a clean install of Windows, when you upgraded the mobo and the CPU

So I did a full system reboot, it still says 4gb

Did you check the fit of the memory as I previously suggested? This:

First, power the system completely down and disconnect the power cable. Make sure both memory modules are fully inserted into the slots. One confirmed, reconnect the power cable and power on.

Press F2 or DEL to access your BIOS. There you can see how much memory the motherboard recognizes.

Yes, if by fit you mean seeing so that the ram is not loose and is sitting properly

Download and run memtest. See here:

http://www.memtest.org/

Download the ISO and burn to disk (or USB drive with a tool like Rufus). Boot from that drive. Run the tests. You may have a defective memory stick or slot. Memtest will help isolate it quickly.

You can also do a sort of test yourself, by installing only a single stick of memory into the primary memory slot, just one at a time, the determine if one is bad.

BTW...any time you work on the innards of your system, make sure all power sources are disconnected and that you also ground yourself to prevent static discharge.

So, I checked My BIOS and turns out DIMM_B1 is not detecting any ram? It says im using 4096mb of ram

xplizitraw · Jan 2, 2018

Problem is that the DIMM_A1 slot is blocket by My CPU cooler...

If only using one fan mounted to your Hyper 212, you can move the fan to the other side of the heatsink. Just be mindful of the fan direction to retain proper airflow with your rear case fan. That should clear up your space issue.

See page 1-5 for the optimal config for installing the memory (DIMM_A2 and DIMM_B2):

COLGeek :

Well, tha's funny you mention it. A person who helped me install my new components told me the fan should be facing upwards... Aswell as the heatsink, and I haven't found it if my MOBO is the issue or the RAM

COLGeek · Jan 2, 2018

xplizitraw :

Upwards is acceptable as well (most orient the other way) as long as you have good airflow.

Note the manual link and memory slot suggestion above.

So, now I have stated that One of my RAM is faulty. My PC wont boot up but all the idle lights (when my PC is turned of on My MOBO and GPU light up
