[SOLVED] So, my mobo says it supports DDR4-2133 / 2400 / 2666 / 2933 / 3200. Would DDR4-3000 work just as fine? What can I do?

The ram isn't on the QVL for the mobo, as DavidMO12 has suggested checking. Ideally you want a set of DIMMS on the QVL to be sure they will work together.

You can get the support list form the links David has posted.

That's not to say the DIMMS you have chosen won't work. Just that it's likely you might have to play with them a little to get them to work.

Thank you! Just wanted to be sure it would work at all. I have a few tech-savvy friends who can do things better than me so I'm sure they can do it. They aren't online so I wasn't able to ask them today.

You're welcome. No probs. Getting them to work takes a little bit of knowledge, but nothing you can't do yourself with a little research. It does take a little tinkering around, so getting them to work is likely, just maybe not at full rated speeds.

Good luck, and if you need further assistance, feel free to PM me :)

QVL is Qualified Vendor List, not Qualified Ram List. There's a difference.

There's only a handful of OEM manufacturers like SkHynix, Samsung, Micron etc who make ram for everybody else. Corsair LPX uses mostly SkHynix, so if you see lpx at 2933, you can pretty much say it'll work at anything less. Without requiring you messing around with it. Most sticks over 3200 are Samsung. Same deal. What you don't see is that Samsung also puts their ic's on g-skill Trident-Z, RipJaws V, Patriot Elite, Adata XPG and many others so even if those models are not represented, the Samsung ic's have been tested, just not in the Vendor.

QVL is just a few kits the mobo vendor has on hand, might be popular around that area, donated prototypes etc. That's all. They don't test every kit from every vendor or you'd have a QVL thousands of pages long, requiring thousands of man hours to complete and compile and hundreds of thousands of dollars in ram costs.

To top it all off is model numbers themselves. They will change due to color, kit, stick, speed, timings. G-skill Trident-Z alone has 6 different color combinations, plus the RGB, which differ between single, double, quad kits, for 4Gb,8Gb 16Gb sticks. And that'll change just for 3200 alone has 14,15,16 CL timings. That's just over 200 different model numbers just for 3200. QVL might have just 1 tested per speed, or even none.

In 30 years of building pc's, I don't believe I've ever actually had an exact match to any listed QVL. G-skill, Corsair, Patriot, Kingston, Crucial sure, but not an exact model match.

For all intents and purposes, QVL is worthless as anything other than a tool to see if certain speeds are viable. If the ram isn't listed, it's simply that it was not tested. Does not mean it will probably need user input to get it to work.

If that's the case, might you know why this guy wasn't having any luck?

https://forums.tomshardware.com/threads/2-different-voltages-for-ram-in-bios.3459004/

GEX416GB3000C15ADC timings
  • DDR4 3000 (PC4 24000)
  • Timing 15-17-17-35
  • Cas Latency 15
  • Voltage 1.35V
  • GeIL Evo X RGB Memory
was on the qvl but

GLS416GB3000C16ADC

DDR4 3000 (PC4 24000)
Timing 16-18-18-36
CAS Latency 16


wasn't and it weren't overclocking to 3000mhz. With all the uncertainty I'd stick with the qvl and stay on the well trodden path.

A slight variation in led colors. etc. I would tolerate a small variation from the qvl in terms of module capacity, a 4 8or 16gb variant though I'm not interested in gimmicky leds, if I knew it was all the same silicon from the same oems.

In that example the timings are different and the guy is having hassle with it. He didn't want to manually enter 1.35 volts but the bios wasn't picking up the overclock. Tried a bios update but didn't say if it worked or not. basically building info on what worked and what and hasn't is a pia.

If I was buying I'd stick with qvl +review = it has been done and it worked rather than non-qvl= bought it, no idea yet, didn't work, hassle, nobody knows if. esp when noobs are frightened to enter bios settings.

You do know who makes the ic's for Patriot Viper 4 ram? Everyone. Whomever is the cheapest at any given time. You can pop the heatsink on 2 kits of identical model PV4 and find Micron, SkHynix, Samsung. Even Crucial (that's Microns mainstream house brand) has used other OEMs in their ram, if it's cheaper on them to buy a batch rather than manufacture their own. Very few are under contract to specifically use one certain OEM and one certain die. G-skill Trident-Z is a perfect example. At 3200, Samsung manufactures all Trident-Z ic's. Samsung is specified to use their B-die in Cas 14, but can use G-die in Cas 16, and either in Cas 15. This was really evident in 1st gen Ryzen, Cas 14 was flawless, 15 was hit or miss, as was even 16 that might have issues with OC to 3200. Of course this was promptly fixed, SkHynix suffered the worst hits.

So even QVL tested model numbers may or may not be honest, if a set of Cas 15 B-die Samsung was tested and someone used a set of Samsung G-die 15, and had issues....

Your example is the same.

No, they were both Geil DIMMs in your example, but it's entirely possible that SkHynix silicon was used for the Cas 15 that was tested and passed easily and a lesser, cheaper OEM brand was used for many others including the Cas 16 model. All depending on who says they'll make X number of sticks for a cheaper price. For all we know, that Cas 15 might have been cherry picked and sent to the mobo vendor for QVL, for just that reason.
