RAM Upgrade causes stuttering

[johnnyboy0g]

Hi, I want to start with saying that I'm new here. Sorry, if I do not know all the in's and out's of what I should include and exclude from the post.

 

So a couple days ago I wanted to give my PC a little gift.
I've been running the same setup for about a year now:

MSI GTX 1080 Gaming X

i7 8700K clocked to 4,3GHz

Asus Z370F Motherboard with a fresh BIOS update.

Ballistix 2x8Gb RAM (BLS8G4D26BFSEK.8FBD)

WD M.2 250Gb, WD 2Tb HDD, Seagate 2Tb HDD

 

I wanted to switch out the 16Gb for a 32Gb kit. I ordered "Corsair Vengeance RGB PRO 3200Mhz 32GB" Kit. It's 2x16Gb and the product number is CMW32GX4M2Z3200C16.

I went about my stroll and switched them out in the exact same DIMM slots; A2 and B2. I enabled the XMP profile pushing them to 3200MHz.
Then I watched some videos and had a look at the glorious amount of RAM in the taskmanager.

 

I thoroughly enjoyed myself, in fact, I wanted to play some Apex and see if things still work. To my disappointment my game stuttered, absolutely crazy stuttering. FPS still shows around 100 FPS even in the middle of a stutterfest.

After asking my roommate about some tips we decided to crosscheck all the different RAM's we have in the house. I gave my old DIMM's to my guy and he tested them on his system with the exact same settings I used to have and they worked flawlessly.

We then tried the new ones in his system and they worked great, at the same time I tried using my older DIMM's with the settings I had for the new ones that caused stuttering. And they also worked just like before. 
So we switched it up and tried using just one DIMM. First we checked them in his system and then mine. In his they worked great, but in mine they caused stuttering. Both of them. He's got an older CPU i7 7700K.

 

At this point I'm lost; I don't know what more to do and what more to check. In every forum I hoped could relate was only regarding people mixing different RAM sticks, which I haven't.

 

And now I'm here. Any help or questions is greatly appreciated. Help me get my game on!

Did you check the QVL list for your motherboard? That will give you a list of compatible RAM kits. If it is on there, I would try setting your CPU to stock settings to see if that changes anything (if it works you may have a degraded memory controller), I would try increasing the voltage to your memory in the BIOS (this can increase stability), and I would try downclocking the RAM to see if that changes anything (again, stability and less strain on your mem controller). Make sure to do these separately. If you still can't find an issue I'd consider a refund and then double up your original kit.

Okay, so I checked the QVL and my exact RAM isn't listed but RAM's with the same configuration 2x16Gb 3200MHz, 1,35V, 16-18-18-36 are listed multiple times. I crosschecked with the new DIMM's productnumber on other High End mobo's and they haven't got the exact RAM listed either. Any thoughts on that?

That could be problematic as there could be any number of variables causing issues if it has not been verified by the Motherboard Vendor. I would still try cranking up the memory voltage as high as 1.5v (it can handle it, don't worry), but start in .025v steps from 1.35v and go up from there (1.375v, 1.4v, 1.425v...). If voltage can't fix the stability issues, then I would go through with a refund and get a QVL certified kit, or just double up your previous kit.

So, seeing as the timings of the older DIMM's are the same. Should I keep those, downclock to 2666MHz (as the older ones) and JUST increase voltage and look for bettering?

So far, decreasing to 2666MHz and keeping 1,35V did nothing.

Downclocking is one way to increase stability, and if that did nothing, then I would just try raising the voltage at XMP settings and then if that doesn't work then I'd stop.

Allright, I've tried downclocking, using the 2 different timing settings listed on the Corsair website for these DIMM's and tried differing voltages. I started by resetting everything in my BIOS. So not even my CPU is overclocked anymore. And then proceeded to try out different settings for the RAM. 

Nothing has worked so far. So I began looking for 32Gb Kits from the QVL but I can't find anyone that sells the exact product number that's listed. Everything else looks the same. But at this point I'm scared trying DIMM's that are theoretically the same, but don't have the same product number.

 

What do?

 

Does anybody have a 2x16Gb kit to recommend for the Z370F motherboard?

 

I even looked at my friends MoBo (He tested the new DIMM's) and saw that they aren't listen on his QVL either, but they worked there?!

Sorry for the late response, I only get on the forums when I'm bored in my university classes, lol. And you want to try and find a QVL-certified kit of RAM because those are guaranteed to work, otherwise you're taking a chance. It could work, it could not. Your safest bet would be doubling up your previous kit, but it's obvious that your current one doesn't work.
