What would be the fastest DDR5 I can pair with a Core i9 13900K on an Asus ROG Strix Z790-F

Here is the RAM QVL list for the Asus ROG Strix Z790-F

https://rog.asus.com/motherboards/rog-strix/rog-strix-z790-f-gaming-wifi-model/helpdesk_qvl_memory/

I would like a kit that will be stable and can set XMP out of box and be good to go with stability for RAM. a 2 X 16GB kit. Want it to be able to run without temp issues nor dedicated RAM fan.

Is there a 7200MHz and above realistic for that at CL32 or lower or no??

Reason being 7200MHz should have IMC run at same speed as 3600MHz DDR4 in Gear 1 as or is that not important. Like is there a performance penalty if the IMC runs at 1600MHz to drive DDR5 6400MHz in Gear 2 instead of 1800MHz to drive 3600MHz DDR4?? Of course all else is better but any latency penalty anyways if IMC frequency is slower??

And which ones are A-die as A-die apparently runs a lot cooler though cannot achieve as tight of timings, but does achiever higher clocks??

Are the G.Skill Trident versions at 7200MHz worth it. Or is that a fail on many IMC and even good DDR5 boards like Z790 appears much improved on vs Z690?

The G.Skill trident versions of RAM seem to be the best performing ones that will actually fit ok under an NH-D15S without having to move fan too much up. The Corsair Dominator are way too tall and Team Force are also a bit tall.

Which of G.Skill Trident versions are the best and are some A die and some M die or all one kind of die??

And if 6800MHz or lower is speed to be achieved, could I get CL28 or lower with 6000 to 6400MHz.

What is typical for this stuff??

No. Not really. Not for the money. 7200 MT/s RAM is very expensive and very early days.

Not sure. I don't know if you will definitely get M Die or so on based on which brand or model within a brand.

I'd probably not stress too much about the speed for now. You can always get better 7200 MT/s RAM later on when it matures a little.

You have a lot of questions and there are a lot of options out there and a lot of unknowns.

I know you've got the budget for expensive RAM, that's fine, and if you reaaallly want to spend the money, just get the fastest RAM on the QVL list that isn't too tall and fits your needs.

My go to buying approach to RAM is to listen to Buildzoid but he hasn't put out a DDR5 buying guide yet. I don't like the Tomshardware buying guide as they tend to recommend RAM and motherboards based on factors that don't actually make sense. e.g. they recommended the Aqua (can't remember which exact chipset) motherboard which was a bog standard motherboard with an OEM waterblock on it that increased the cost by an extra $200/£200 which made zero sense or RAM that can't overclock because it's Samsung DDR5 B die that sucks and isn't cheap either.

It's really up to you and what you want though and if you have to have it, go for it.

But is it true and likely fastest RAM on the list may still fail at rated timings depending on IMC lottery?? Especially when pushing it above 6400?? I notice that RAM above 6400 is hard to find and the ones there are, seem rare or out of stock.

I don't know enough to say yes. All I know is that RAM is dropping in price like a stone so why would you spend the extra £150 on a top of the range kit when a faster kit will be half the price in a years time?

Trying to future proof and yeah I know I know something always better comes, but want a super fast system now that will still be solid in a few years time. Like a set and forget it mentality for an RTX 4090 at 1440p with a super fast clocked all P core 13900K on large air cooler e-cores off.

Then sure, go ahead. Get the best kit you can find.


I will wager you £10 that you get the itch to upgrade in a years time and pull the trigger on a better kit of RAM or a 5090 ti or something. Always happens but as long as you are happy with the purchase, that's all that matters.

Spending huge amounts of money on fast ram when a cheap 5200/5600 kit gives you practically the same performance won't help you future proof I'm afraid. If you're a gamer just buy "good enough" and upgrade it in a few years, if you dropped to a 13600K and 5200/5600 you'd save enough money for practically a whole new base in 3-4 years.
 
I'm currently running DDR5 8000 on a 12900KS (Z690), granted not quiet XMP but there is a lot of headroom in it with that correct modules and board.

I need to get around to installing the 13900K at some point when I get 5 minutes.

Have they fixed the performance issues of 13th gen on 690 yet?

Is that a general question or a EVGA spefic question? As 2.0.3 corrects a lot of the problems

I have also not tried my 13900K in this board, as its going in ether the Z790 Apex or Dark

oh okay, it was just the way you said you had a 690 and were going to be installing a 13900k I assumed you meant it was going in that board
