Running Windows 10 Pro. HWinFO shows 4GB. Memcheck shows no error. Thoughts? Defective stick? Incompatible system?
 
Are you using a 64bit OS?
Have you also checked in BIOS to see what memory size shows up over there?
 
Where did you get the ram? Maybe it’s incorrectly labelled.

Also, you could try a bios upgrade. And as above, make sure OS is 64bit otherwise I think it’s capped at 4gb.
 
check the frequency and your motherboard & cpu max support..
what is your other specss anyway

It is 64bit. I'll try the BIOS update. They told me that too in the post I made on Reddit.

Intel Core i7-4770. What should I compare exactly?

Updated BIOS, freaked out a little because Windows wouldn't start until I went into Safe Mode and restarted and it worked, but the RAM issue is still not resolved.
Thoughts?
 
There are counterfeit RAM on lots of marketplaces. I got some laptop memory that did not perform great. All the sticks had the same serial number in CPU-Z.
Maybe it is counterfeit and they put the wrong sticker on it to fool people.
 
Where did you purchase the RAM stick? A legit source I assume?

PS: Are you in a position to try it in another system or are you limited?
 
Does the RAM have a heatsink on it? You can try and check the numbers on the memory chips to confirm if it actually has 8GB or 4GB.

I purchased it from a local shop in my town.

Using HWiNFO64, I paste the stick model into Google, and it's accurate. Can the model number be faked on a fake stick?

Kinda limited to my desktop, I'll take it back to the shop and ask them to try it there. If it shows 4GB there, too, can we conclude it's a fake?

If by heatsink you mean the blue plastic on top, yes. It's a Corsair. How to check what you said?
 
Do you have another pc to check? Or use a friend's one to test the ram?
 
take a picture of your bios showing ram specifications. take it back to store and explain it. see if they will test the ram in another computer for you. or replace it.

could be they took you for a fool and sold you 4gb while saying it's 8gb.

if you have time, run through these google hits and run the troubleshooting they recommend

Well as experience the CPU might not be making full contact with the motherboard, by accident I broke some pins from the motherboard that make contact with the CPU after fixing those peans the computer turn on but was recognizing only one memory bank no 2 I have a i7 4790 I believe we have the same type of socket also I recomend you to check on the bios if they show as a set of 2 maybe but maybe the person how sold you the memories sold you a set of two both memories making 4GB, test the memories one at the time and if you can share some details from the memories will be awesome download speecy and go to ram and show us a few more details about the ram, sorry for writing too much but let's try the following too, clean the contacts of the ram with an eraser carefully always carefully I do that to clean the contacts, in your motherboard with contact cleaner or compress aird or something like that clean the memories slots, if after all that still the same, I recomend you to check the CPU slot and see if it is damaged as it happend to me and that is why was recognizing only one memory bank no two, hope this help you also check the memory one at the time in each memory slot and check if it shows you the same information for both memories.
 
Do you mind sharing a pic of the memory stick both sides up close?

Thanks for the pics. I don't see anything that would make me think they are counterfeit. They are the blue version of these sticks. They also have a black version.

These look the same as: https://www.ebay.com/itm/165455444652

Can you boot your computer with one stick? What does it say for memory then? Then try the other stick only. Maybe you have a bad memory slot. If you have 4 slots try using the other 2 you have not used yet.

I tried it on all the slots, alone, with the other one, before and after BIOS update, and the issue was never resolved.

The town where I'm at right now is a boondocks, and the tech sold here is sus. Stick might be a dud, defective from manufacture.

This make no sense at all, the memory it self should have a sticker on, not the outside heatsink that sounds wrong .

Take that back, don't sound good a con .

A motherboard will show the correct mb in the bios full stop .

Get a copy of your motherboard an make sure it the correct ram .
(( that prove your doing it right to the shop))

Sound like the shop made huge mistake or selling 4 for 8 not fare .
 
1600 DDR3 ram speed is the normal speed for DDR3. Not overclocked or anything. I dont think that is the problem.
