1) does it mean that if I install 2 sticks with frequency 7600 in dual channel mode - I will waste it and will get max 6400? 
meaning there’s no point in buying 7600 RAM and target 2x16 6400 Mhz? 
1) and if in the future I would add 2 more same sticks - I would again lose in frequency from 6400 to 5600?

 

No, that's what they say it's most likely to work. When you go to BIOS and enable XMP the RAM will still run at whatever speed it's configured to... but it may not work well or at all the higher you go with the speed.

For 2 sticks of Single Rank memory you should be mostly fine up to 7600MT/s but for 4 sticks of RAM that may not be achievable at all as the more sticks you add the more stress there is on the memory controller.

Hi everyone,

 I’m doing first build after loooong break and I got puzzled with this:

 I’ve picked up motherboard, which states supported RAM frequency 7800 (MPG Z790 CARBON MAX WIFI) and I picked RAM 2x16 with 7600 frequency (G. SKILL 32GB KIT DDR5 7600MHz CL36 Trident Z5 RGB Black)

but then I saw this at MB specs:


Memory Support 7800+(OC)/ 7600(OC)/ 7400(OC)/ 7200(OC)/ 7000(OC)/ 6800(OC)/ 6600(OC)/ 6400(OC)/ 6200(OC)/ 6000(OC)/ 5800(OC)/ 5600(JEDEC)/ 5400(JEDEC)/ 5200(JEDEC)/ 5000(JEDEC)/ 4800(JEDEC) MHz
Max. overclocking frequency:
• 1DPC 1R Max speed up to 7800+ MHz
• 1DPC 2R Max speed up to 6600+ MHz
• 2DPC 1R Max speed up to 6400+ MHz
• 2DPC 2R Max speed up to 5600+ MHz

 

1) does it mean that if I install 2 sticks with frequency 7600 in dual channel mode - I will waste it and will get max 6400? 
meaning there’s no point in buying 7600 RAM and target 2x16 6400 Mhz? 
1) and if in the future I would add 2 more same sticks - I would again lose in frequency from 6400 to 5600?

Okay, 2 things:

 

1) AMD's 7000 series is probably a better deal than Intels 14th gen

2) Past a certain point, faster ram stops being worth while, I put that point at about DDR5 5600/6000 CL 36

I might be experienced, but I'm human and I do make mistakes. Trust but Verify! I edit my messages after sending them alot, please refresh before posting your reply. Please try to be clear and specific, you'll get a better answer. Please remember to mark solutions once you have the information you need. Expand this signature for common PC building advice, a short bio and a list of my components.

 

Common build advice:

1) Buy the cheapest (well reviewed) motherboard that has the features you need. Paying more typically only gets you features you won’t use. 2) only get as much RAM as you need, getting more won’t (typically) make your PC faster. 3) While I recommend getting an NVMe drive, you don’t need to splurge for an expensive drive with DRam cache, DRamless drives are fine for gamers. 4) paying for looks is fine, just don’t break the bank. 5) Tower coolers are usually good enough, unless you go top tier Intel or plan on OCing. 6) OCing is a dead meme, you probably shouldn’t bother. 7) "Bottlenecks" rarely matter and "Future-proofing" is a myth. 8) AIOs don't noticeably improve performance past 240mm and don't improve at all past 360mm. 9) RTFM.

Thanks a lot! Exactly what I was looking for

Well, there are two points from my side on AMD - personal bad experience after which I really don’t want to return to AMD ever again even if it will be winning every challenge vs Intel 😂

General stability and compatibility - subjective, but after reading lots of threads, lots of reviews and forums and watching videos - compatibility/stability and other issues count - Intel kind of wins (in my eyes)

Plus - I don’t plan to “upgrade in next like 5 years - so I don’t care about 14th gen being dead end. And once I’ll go for change - I prefer to sell whole thing and buy all new 😂

 

Regarding RAM speed - you are right. My only reason to go as high as possible now is, as I mentioned above - I don’t plan to upgrade for a while, so I want it to last as ling as possible

This isn't worth it. A sold 32GB set costs about $90 atm (a price that is dropping quite fast), whereas the GSkill set costs about $190 (also a price that is dropping very fast). I think by the time a 7600 Mhz set is worth buying (if it ever is) it's price will have dropped down to where 16GB DDR4 3200 sets were a few years ago ($40-60).

 

Buying the 7600 kit now won't net you any performance in the short term and will cost more in the long term.

 

I'd also like to ask why your selecting a such an expensive motherboard? are there some features you need, cause a $400 motherboard really isn't worth it unless you have a really good reason.

Thanks, I’ll consider your thought on RAM. 
 

regarding motherboard - my point is - pretty much top (or get as high as possible) in every aspect - so going with i7 14th gen, 4090, 2 nvme drives (1tb for OS and important stuff and 2tb for games) - so I want MB to support maximum of throughput. On top of that - was looking for MB which would support as high RAM frequency as possible. 
and final on top of that - simple and native support of case fans, AIO + usb c and stuff

So, my choice landed on this one 🙂

 

and I have some sentimental feelings towards MSI as I had (and still have somewhere) a gaming laptop from them, which served me very well veeeeery long 😅

 

and #2 on top of that - my approach to chosing components is - sort from high to low and select ~2nd/3rd from the top 😂

I think you could get all of these things without getting a Z790 motherboard. But it's your money 🙂
