2700x RAM Compatibility

[DefinitelyNotTom]

Anyone know a way to find out if F4-3200C15D-32GTZKW will work well with an x470 mobo? I was about set on getting ryzen instead of intel, but amd cpus being notorious for being bad about memory compatibility is really tempting me to just get a 8700. I read that for last year's ryzens and mobos many of the above 14 CAS was seeming to have issues and notice mine is 15 CAS.

mobos I was thinking about were x470 asrock or asus ones.

At this product page, notice it only shows intel cpu motherboards!

To differentiate between the new AMD-optimized Trident Z RGB kits from the original, look for the "X" at the end of the Trident Z RGB model numbers.

Well I already have the non-returnable RAM that is not optimized for it, so I wonder if I should just go with intel, just to have peace of mind on the RAM, even though the ryzen would have been good for video editing...

Also, notice on the following motherboard specs page it says ram speed and supported speed both at 2933 for a 3200 RAM module. Why would it list both at 2933, when the rated speed is 3200?

And the model number is slightly different on it. Notice on the entire list on there only 1 module is 3200 or above supported.

Those QVL lists are always outdated and hopelessly inadequate, they just list what (hopefully) they tested with particular MB. One just can't count on them. BIOS versions also may change compatibility options and eventual OC is not even mentioned. Ryzen2 + x470 chipset practically guarantee 3200MHz with any RAM with XMP rated at that frequency. Keep in mind that DDR4 practical starting frequency is 2133MHz and everything above that is considered OC, either by XMP or manually.

G.Skill themselves disagree with this, so I just can't chance it. They just told me the kit I bought would not work well with an AMD one unless I get something like the asus hero that costs $300. No way am I paying $300 for a mobo. I won't even pay half that, in fact. This was my point, just because other people's kits not optimized for amd work doesn't mean every single variation will and when G.Skill themselves tell me this, I'd be really risking a decently expensive build by using incompatible memory. And I really wanted the 2700x.... but only other alternative is sell the RAM, but it would be a mess if the buyer then says it doesn't work.

Still getting responses all over the place on this. Some saying if it says it supports 3200, I am fine. Some saying it should be used with intel.

I would imagine that at the very least you should be able to get 3200 cl16. Probably 3400 -3466 cl16. I would try Ryzen DRAM calculator downloadable app for Windows. Plug in Ram rated speeds and see what it comes up with. I dont see any of 3200 CL15's on QVL' however if you are willing & able to spend some time plugging in all the timings I am sure you will be able to at least hit 3200. Also try to see if it is a Samsung B die chip or something else. Samsung B-die plays very well with all Ryzens. I got my gskill Trident 3200 CL14 sticks stable at 3466 CL14 stable by using Ryzen DRAM calculator settings, a higher DRAM voltage & a slight bump to SOC voltage (to stabilize DRAM controller) on my Asus Strix X470-f & Ryzen 7 1700 no problem.

For the motherboard I bought, it lists the same kit I have, but just a different color (the model name is the same except the 2 letters at the end for color). But it says it will run at 2997 or something like that.

I don't have much choice really. I have every part bought and it would be one big headache trying to sell either the RAM or the mobo and cpu. As anyone can tell from classifieds, I am already screwed over with my gpu purchases. I first bought a rx 580, thought that was a good choice for my needs, only to find out the program I want to use is messed up with amd cards. So then I bought a gtx 1060 and now nobody is buying my unopened rx 580 and are making crazy low offers for it on ebay because they keep thinking it's the same model as another on good sales, even though mine is better (the mk2 version of the card they think it is).

So I am already stuck trying to sell at least 1 part without losing much money and it's becoming difficult. I could have bought a freakin 1080 for the price of both of these cards.

And, btw, if you look at the AVL on some of these mobos, it's VERY, VERY, VERY limited in what is listed as running above 3000. There's like a whopping 1 32gb kit from g.skill I think, for instance.
