DDR4 Motherboard for 13900k

629 13
Hey guys! I'm planning on upgrading to the 13900k but keeping my DDR4 until really fast DDR5 becomes wildly available, but I don't know which DDR4 board to pick.
I have a 4x8GB kit of 4000Mhz CL15 1.5v kit that's got the best S8B chips so they should be able to hit some nice speeds with a good IMC and good motherboard.

As far as the 13900k goes, I believe it should be able to drive this kit past 4000Mhz with some nice timings, but for the motherboard, I don't know which one would be best for DDR4 overclocking.

So far I got the TUF GAMING Z790-PLUS D4 in my basket, as its fairly cheap and has all the support I need, but I really don't know how good it is with DDR4 overclocking, so I turn to you for help.

I am open to your recommendations.
Board just needs to have good VRM cooling and capable DDR4 overclocking, that's it.

You don't need to specify a high end board for DDR4 as agent mentioned.

Asus Tuf or MSI Pro-A / Tomahawk are plenty. G1 will only go up to 4200-4300 at most, any higher on DDR4 you lose performance from G2.

Personally I picked the Tomahawk for external cmos clear button and stronger VRMs than the other ones in the same price category, I'd recommend that one as it has the most features for the price.

More important for DDR4 OC is the CPU's IMC, if you want a good shot at higher G1 capability, consider going for the 13900KS as higher bins usually have better IMC.

Thanks for the replies guys, much appreciated!
Seems the MSI MAG Z790 TOMAHAWK WIFI DDR4 is the best fit for me so I'll go with this one.
Cheers!

I just did a build using the TUF GAMING Z790-PLUS D4 for my nephew. He liked the looks of it and cost. I didnt look at it when he ordered the components.

GSkill Trident Royal 4800mhz will only run as fast as 4500mhz with decent timings. It is a decent board. Great features. But if you are an overclocker, this is not the board you want. No Clear CMOS button and no onboard power or reset. Those are deal breakers for me.

You really don't want to be running at 4500, it will be in gear 2 which halves IMC latency.

In a quick test I did, even 4800CL17 G2 was slower in Civ 6 turn times than 4000CL14 G1. 4500 G2 not worth running at all.

My 12600k can't fully stabilize 4000G1 with any CPU overclock which is the only reason I run it at 4800G2, but even 3800G1 likely still better.

*** is this gear 2 stuff? Memory got gears now? You talking CR1 and CR2 in timings?

Nope, do some searching for it, lots written on this forum about it.

Its an IMC setting not ram that is necessary for DDR5 frequencies.

Gear 1 = 1:1 IMC : Ram, Gear 2 = 1:2 IMC : Ram.

When running in G2, the IMC frequency is halved and completely kills the latency. It takes DDR5 running 7000+ tuned to match gear 1 4000+ latency.

Basically 12th / 13th gen has destroyed high frequency DDR4, you lose a lot of performance running DDR4 in gear 2,

4000G1 = 2000 ram : 2000 IMC

4500G2 = 2250 ram : 1125 IMC.

This is also why there is very little difference between 3600CL16 DDR4 and 6000CL32 DDR5. You sacrifice latency for bandwidth.

So gear 1 and gear 2 are what we used to call ‘command rate’ 1T or 2T?
No.

It's the clock ratio between the CPUs IMC (integrated memory controller) and the memory sticks frequency.

at 1:1 memory clocked at 4000 means IMC = 4000. At 1:2. IMC = 2000

Half the ram speed for actual numbers.

4000 ram = 2000 frequency and IMC in G1, 2000 / 1000 in G2.

Ok, cool. Never even looked at that. First 12900XX I messed with. I am still at 10850K. lol I was mostly concerned with fastest stable I could get memory. Didnt have much time to mess with the PC as nephue was itching to have it. No idea what gear. Speed/Timings are 4533mhz, 17-18-18-36 CR1

Is that on 12900XX or 10850K?

10th gen didnt have gears. Everything else after you need to be on gear 1 for DDR4.

4533 will not be in gear 1, it doesn't matter how high the ram goes if its in gear 2, you are losing a lot of performance at just 4533 in G2.
