Can different RAM set cause problems?

[Assaf Chamoy]

Hey!

I've posted recently a post about my problem here, but there's some updates with it so I decided to write a new post: 

 

 I have resently built a new pc out of parts I bought from newegg on the last black friday (November 2020):

I9 10850k, Gigabyte Vision g z490 Mobo, Gskill TridentZ royal 4000mhz (8x2, 8x2) - 32GB, Rtx 3080 gigabyte vision in a combo with gigabyte 850W psu.

So by all means, a nice gaming pc. But it won't shut down properly.. Ill explain: Shut down via windows, everything shuts down - keyboard, mouse, monitor, but the actual pc - led lights, cpu cooler fans and rgb, and ram lighting stays on! The only way to shut the pc down from this state is to long press on the power button and force it to shut down.. hate to do it! It happens only after a fair gaming session or a decent work with the pc for a couple of hours, so if I turn it on and after few minutes shut it down it does not happen.

So I talked to gigabyte to see of its something with the mobo - they told me to try with two sticks of ram at a time, and the problem seem to not recurring that way. Checked the other pair to see mabe they are faulty - works just fine!

So, gigabyte referred me to GSkill support because my ram didnt pass the compatibility tests with the mobo so it is not on their list, and maybe gskill will provide me with some custom memory preset that might solve my problem.

So I did, GSkill support told me that the root of the problem is that I purchased two packages of memory pairs instead of 1 x 4 sticks. The problem with that, is even the model is exactly the same, the two packages didnt pass compatibility tests with each-other, these can cause some compatibility issues such as mine.

They provided me some custom settings for the timing, voltage and frequency, but no luck

Is there anything else I should try to solve my annoying issue?

Thanks!

No. 

 

If gigabyte says it won't work then it won't work, for now. 

 

Ram compatibility has come up a lot.  In your case, it just can't handle 4 sticks of that ram.  You are lucky it works with 2 as sometimes unlisted ram just doesn't work at all. 

 

For any new builders out there, you should always get ram that is on the qvl.

Most of your performance setups will be 2x8gb in slots A2 and B2. 

Additional memory amount and DIMM count puts additional stress on the memory controller.

So for high frequency performance, just run 2 sticks.

 

Nobody should strictly follow QVL while new kits are released and the QVL list only pertains to the bios the board was released with.

Exactly what I think, but it is a fact that I have some real problems now..

Should I put the frequency down a bit to see if it release some stress from the memory controller?

But the problem happens even without XMP or any memory oc..

What would you do?

I'd pull 2 sticks of memory....

When there are thousands of RAM sets out there, it’s close to impossible to test every single one. While the QVL are guaranteed to work, there is a very high chance that sets not on the QVL will also work fine.

If you're willing to take the chance and spend the money then go for it.  There are no doubt hundreds of available configurations and some will work flawlessly, some won't work properly and some won't work at all.

 

If you want the assurance that your ram will function properly the first time then go off the qvl.  The qvls do get updated occasionally but mainly for popular and newer models.

 

I have seen many new builders who don't understand this and wondering why their expensive components don't work out of the box, ddr4 is ddr4 right? 

 

Some systems can get away with mismatched speeds and capacities, but performance will suffer.

 

Buying 4000mhz ram and down clocking it is, Imo, a waste of time and money performance wise but it would sure look purdy.

I am certainely not a new builder, I have never ran into these issues on any of my systems and I have never even thought of checking the qvl prior buying a mobo or a memory set.

Everything works just fine on my system beside it! If i'll restart the pc before shutting down every time, it will shut down properly. 

The motherboard should be fine frequency wise, and Imo should support even higher frequencies just fine.. I just dont get it.. why it works fine on one system and the other ran into these kind of issues... so frustrating
