You have to be careful, there are different rating on RAM like Type A, B, AB, and O Negative. There's a chart that explains it all but it depends on the day of the week.

[NoobSvCy]

and my friend casually uses almost 4 brands RAMs on 4 slots.

[asfandrkhan]

This is the best channel in the world for anyone starting off. They answer all of the key questions no one answers so quickly.

[TCGamingCosti]

Great answer. Really explained the whole difference between intel and amd. Thank you!

[draebo]

Sound advice as usual Mr Tech. I see you've begun doing your own ads. Nice touch!! Have a great day!

[daltonprescott]

As an avid pc builder, I've done countless ram upgrades over the years for myself and family and friends. If you mix kits there's a small chance it wont work, but generally it's fine.
However for overclocked ram, you can kiss your rated speeds goodbye, you will likely have to use a slower clock speed or they will only run at default 2133 speeds.

I recommend buying your ram kit from a place that accepts returns, bring it home, test if your system posts, then run memtest. If it doesn't work, return your ram and try again.

[OleBrumHonning]

What do you put in the mix set? 2 set with g.skill purchased at different times or 1 set g.skill and 1 set hyper x?

I mean, as you said this is anecdotal, but my system with a Ryzen 7 3800x and MSI B450 Tomahawk, I originally had only 3 Dimm slots populated each with 16GB Corsair Vengeance LPX 3000mHz. I wanted to fill it up all the way and bought a 4th stick of the same speed, capacity and brand. The only difference was the memory timings, where my original kit supported 15-17-17-35 and the new one 16-18-18-38.

To make it work, I went and changed the memory profiles in the Bios to run at 3200mHz but at slower timings. The system was having issues with stability and not booting prior to the RAM speed adjustments in bios.

For Ryzen, the chances of stability are higher if you're able to find out the exact chips used in each RAM stick. For example, a few years ago (and possibly still to this day), the G.Skill FlareX series and the TeamGroup T-Dark Pro 3200 kits used/use the Samsung B-Die chips, which run solid at CL 14.

I just found yall's channel, I love it. Yall are very informative and you both look very happy together doing what you do. Keep up the great work. Thank you!

[araisikewai]

For a Ryzen setup, what if they're different kits but from the same vendor/manufacturer and the same model down to the production code, just that the series number not pairing?

[alexgottmituns]

Thank you for the explanation! I had a 16 GB kit (2x8, Tridentz neo single rank memory) which I replaced with a 32gb kit (2x16 tridentz neo dual rank) for my Asus Tuff x570 pro board/ 3800X rig. Day and night difference in framerates in 1080p 25%. In 1440, about 5% only. Video card is the 3080 FTW

And in case you were wondering "do different RAM kits have issues." Yes they do, very often. Like he explained designs and architecture plays a huge role, but also any kit difference at all is a 50/50 chance that it simply won't register on your machine at the same time. I had 2 DDR3 kits both from Radeon both the R9 series, one was a (2x8GB)16GB 2133 the other was a (2x8GB)16GB 2400 and it REFUSED to register them both at the same time, it would only run at the lower kit. So my best advice to you is if you get a kit always futureproof by getting a kit that you can later upgrade with the same exact ones. Because if you don't you might have to replace the entire kit at quite a large expense to your wallet.

I accompanied a friend to a computer store to buy/build a computer recently. He went with an AMD offering on an X570 motherboard. They didn't have a 32GB kit on hand so wanted to use two 16GB kits (DDR4 3200 CAS 16). I said okay, but only if they would do a full memory test after the build.

Finally the machine booted into Windows 10 and they kicked off the memory test which immediately reported errors. They ran the test with each stick of RAM separately and those tests passed. As each test takes a while to complete and we were all getting tired, so I asked for a refund on the RAM and went to another shop to pick up a 32GB pack (same speed, but actually saved my friend $9). It worked like a charm, as I knew it would.

The tech guy at the store said they never had that problem with mixing RAM before. I asked if they ever ran memory tests to verify that the RAM was truly working and it was clear they had not. I bet they sent out a bunch of systems that seemed to work fine only for occasional unexplained crashes to occur.

Personally I won't risk mixing RAM kits if I can't return it if it doesn't work. Just not worth it to me, particularly since I live in Peru and travel to the US to buy most of my computer gear.

Sure, you can always make it work by relaxing the timings, but then you're not getting what you paid for.

[seanpetersen]

This was my question in the live stream! Haha

[FangerZero]

I mixed and matched two different sets of ram but I made sure the Speeds and CL were all the same, only difference was the capacity. Seems to not have any problems. Granted I am running a 2600k w/ those mixed kits.

[scottbadman]

I built my PC with 2x8 HyperX 3200Mhz, and later added a second identical kit on my r5 3600 system. XMP @ 3200Mhz before and after, zero issues and full 32GB available

[BSDMDESIGNS]

I am in the process of building my first amd system. I'm going with the 3950x and aorus x570 master. I bought 2 sets of 2x8gb 3600 cl16 ram. I haven't installed them yet, do you think it would work or should I return them and get a set of 4 at 32gb? Please advise. Thanks

[Dogspark]

i've been loving your recent videos I don't know if you'd had this format for awhile or not but please keep it up

[RaidenB]

If I mix kits, I usually just make sure the voltage, MHz and CL timings are the same. However I've only done this with AMD's AM2 to AM3+ processors, including the FX series
