Hello -
I’m receiving a pre built machine that has HyperX Fury 32gb dual Chan 3400mhz ram.
I already have a Crucial Ballistix 32gb kit of 3600mhz frequency ram but it is CL16 and I’m fairly confident the HyperX Fury is closer to CL18 or so from what I can find.
I’ve seen a lot of videos saying I can mix if I have two kits, but I imagine my faster, lower latency memory will slow down to match the included ram.
Options:
-
Doesn’t matter, 64gb is great even if the it doesn’t match and runs at the slower speed and latency.
-
It won’t work, don’t bother.
-
Sell the HyperX Fury kit and replace with identical aftermarket kit to what I have already
I would be able to use 64gb ram for my work work, so it’s not just for games. Cheers.
Thank you. I’ve watched almost every YouTube on the topic, including the one linked.
They all say it is possible. My question boils down to if it is worth the performance hit or if it is worth the trouble to resell the oem dimms
If you have an Intel CPU it will make zero difference, Intel do not care that much about ram speeds.
If you have an AMD CPU try it and see. Run three benchmarks, old ram, new ram, both together.
The purists are going to say stick to matched sets of identical ram but in reality that has not really caused issues since the bad old days of DDR2 unless you are doing some serious overclocking.

AMD 5950x cpu is in my prebuilt along with a 3090 and the 32gb 3400mhz ram. The ram was an upgrade I didn’t ask for since I already had my Crucial 3600mhz cl16 ram. So I’m trying to decide what to do with it.
Is it possible? Yes.
Should you do it? No.

Option 1. That is what mine is doing now.
Memory Timings done by the motherboard during POST
(prior to running the BIOS) will configure the memory for the PC to run
with all the memory that is installed (if it can determine a suitable set of parameters).

I tried that and it causes all sort of issues and error.

Yes, I once had that problem.
With an ASUS MB. And I am an ASUS fan.
I bought a Gigabyte MB and it had no problems.
I think you’re making live difficult for yourself. Hardware working together is not a simple question of Yes or No.
Seems to me that you already have the Ballistix and will get the Hyper Fury in the new rig. So just try and see what’ll happen. What do you have to lose? Let them run on Auto and you’ll see immediately whether they run together or not. You can also check the timings with cpu-z. Then try some overclocking. If you are not satisfied sell the set you don’t like and get an identical new one
On thing I noticed however: even if you have supposedly identical Ram chips they sometimes don’t run well together. I have 4 HyperX 3600 - same model, almost identical serial number, bought them together. But they only run stable at 3400 if I put them in, in a specific order. If I change the order - no matter what I tried- the MB will give me a POST error as soon as I push them above 3000, and even at 2800 MSFS will crash every time.

You’re right.
It does depend on the mix and how good the “Memory Timing” software is on the motherboard.
I had 32 GB of G.Skill 3400 Mhz.. Wanted to add 32 GB.
Searching the internet, I could not find anyone who was selling it anymore.
I had to buy another brand/spec of 3400.
I would think there are a lot of people increasing their memory (or replacing a bad stick) and due to whatever reason (price, availability) end up with non matched memory.
You can only buy it and try it. If it runs at the speed you are content with,
keep it. If not, return it.
If you can afford it, replace it altogether.

Just try it and see.
You are not mixing different ram in the same bank, you are mixing two different matched pairs in different banks. It might fail to boot. or it might work fine with only a barely noticeable performance hit. If it does boot OK your RAM being 5% or so slower will probably translate to something like a 0.5% or less frame rate hit in game. You will never know till you try it.
The exception will be if you intend to do some serious overclocking in which case you want as many things in your favor as possible including matched ram.
This would be the equivalent of walking while wearing a running shoes on your right foot. While also wearing high heels stiletto on your left foot.

If the different ram works at all, I suspect the difference " in game " will be minimal.
We mix and match ram at work all the time in both clients and servers (unless it is one of our big genetics servers with a few terabytes of ram ) - though admittedly our IT manager has banned AMD after a lot of driver issues so we mainly deal with Intel desktop/Xeon processors not AMD .
But if you are unsure and tend to think the people who claim it will have some massive noticeable effect on your frame rate in MSFS have a point, then JUST TEST IT. Look for a change in FPS and also a change in stutters which is where ram speed is more likely to actually matter rather than frame rates.
My personal hunch is there is al lot of theory crafting going on, rather than basing it on real world experience with real ram in MSFS.
However you never know they may have a point, especially since your processor is AMD which can be finicky about RAM, so just TEST it out. We could argue in this thread forever based on book theories and what YouTube experts say and reddit but the best solution is test the different combos in the real PC with the real game.
Yes you can mix memory.
But it is not best practice and is NOT recommended.
And if you want to avoid all the hassle of selling your inferior memory kit, my best advice:
make someone’s day and give it away.
Here’s a quick read on Infinity Fabric (now called Architecture?) in the AMD universe.
Hi @FlyByDriveBy ,
I would put the same RAM in as my tests with FS2020 tell me RAM makes a huge difference to the overall performance. I’d speculate that many of the individuals suffering terribe performance with high end graphics cards have slow RAM!

Sell the lesser performing sticks. Add a little money and get a matching set.
