Motherboard/memory compatibility question

[Cazom]

I am slightly confused by the motherboard specification detailing on the memory section. For reference I am using 2x 32gb 6400mhz corsair sticks, would they run on this speed on a motherboard that supports the following?

 

1DPC 1R Up to 7200+ MHz (OC), 4800 MHz Natively.
1DPC 2R Up to 6000+ MHz (OC), 4400 MHz Natively.
2DPC 1R Up to 5600+ MHz (OC), 4000 MHz Natively.
2DPC 2R Up to 4800+ MHz (OC), 3600 MHz Natively.

 

Does this mean it can only run at greater than 6000 mhz if using 1 stick? The motherboard memory listings are very sparse, does this suggest that it wont be compatible?

 

Thank you

That's the official support, they get that from testing and validation. But notice how a + is added to the end of the numbers, meaning that you could still technically get higher.

There's not a guarantee that you can get those OC speeds in general though. If you don't get 6400 off the bat, you might need some tweaking.

What motherboard are you looking at? The advertised max frequencies are rarely accurate as to what a motherboard can support. 

 

By that list, yes, 6000 is what 2x32GB will run at. Whether or not that's actually accurate is up for debate though.

^^^

either the board overshoots or is incapable of advertised ram freq

 

Spoiler

Heres an example of a motherboard overshooting its advertised ram freq capabilities

 

X58a ud3r only rated for 2200 ddr3 but im running it at 3136 ddr3 on air with an i7 930 and problably higher when i get a better cpu

 

This is a pretty extreme example and you problably wont be seeing stuff like this nowadays

 

For an example you can see nowadays theres boards like the z790 apex encore rated for 8400 but some ppl have managed 8800+, not everyone can hit those speeds but thats intels fault for having such inconsistent ddr5 imcs, board is likely capable of much more but held back by its platform and cpu imcs

 

Spoiler

Heres an example of a board that is incapable of its advertised ram freq atleast without a golden chip under ln2 for 260+ bclk

 

Dont really have any pics cause it was an unremarkable board on a rather unremarkable platform but i did own one of these and yea 2600 ddr3 not in a million years, even if i wasnt stuck with my absolute garbage sample of an i3 530 that wont bclk id still be looking at 2200 ddr3 at most on air with a decent chip

 

heres 2600 ddr3 on 1156 but as you can see needs ln2 and a golden chip so i deem this board incapable and way too overzealous in its advertising

 

 

Cant trust advertised specs on mobos

If youd like a more accurate representation as to what the board can do just look for oc results from other ppl online

Thank you for the replies, so the best way is to fit them together and see if it works?

Actually looking at one of your previous recommendations:

B760M PG Riptide and I am comparing it against a MPG Z790I EDGE WIFI paired with a 14700k and 2x 6400mHZ 32 sticks from Corsair

The edge will definitely OC better than the Riptide, though most of ASRock's LGA 1700 boards they're pretty conservative with the max supported memory speed with the exception of the Nova. 6400 would probably be the limit of that board with 2x32GB, though it should be possible to get working. The Edge, on the other hand, is more optimistic about what speeds would work, though not by a whole lot.
