G.Skill recently announced two new series of DDR4 memory geared towards AMD’s new AM4 platform and Ryzen CPUs. The FORTIS series comes in kits up to 64 GB at 2400 MHz while the Flare X series features kits up to 32 GB at 3466 MHz.

The FORTIS series come in black with graphics on the sides. At launch, there will be kits in 16 GB, 32 GB, and 64 GB capacities clocked at 2,133 and 2,400 MHz. These kits run at 1.2V.

Flare X reportedly uses “carefully selected” IC chips that have been tested and validated for the AM4 platform and Ryzen processors. These kits run at 1.35V out of the box and come in 16 GB, 32 GB, and 64 GB at 3200 MHz with 14-14-14-34 timings or in a 16 GB (2x8GB) kit clocked at 3466 MHz with 16-16-16-36 timings.

It is worth noting that Ryzen officially supports memory up to 3200 MHz without needing to overclock the bus speed using one of eight memory straps/dividers (this is apparently a limitation of the UEFI and not Ryzen's memory controllers). In order to take advantage of DDR4 with higher clocks, you will need to overclock the base clock (which is made easier/possible on motherboards with external clock generators). G.Skill showed two examples using a Ryzen 7 1700 and an Asus Crosshair VI Hero motherboard where they got a 4x16GB kit clocked at 3467MHz (16-16-16-36 CR1) by setting a 25.4 x multiplier and 118.16 MHz bus speed. The other example was DDR4 at 3200 MHz with a multiplier of 28.4 and 119.99 MHz bus speed. It is interesting that they were able to push the bus speed that high while maintaining stability. G.Skill posted two CPU-Z validation screen shots on its news announcement.

G.Skill did not announce pricing, but it did state the new memory kits would be available later this month. Looking around on Newegg, it seems some of the lower speed kits with 4GB DIMMs are available right now but the new kits with higher clocks and 8GB and 16GB DIMMs are not available yet. The less exciting Fortis series does appear to be available though with a 2x8GB 16GB DDR4-2400 priced at $124.99. Even the Fortis series isn’t fully launched yet though since the 2x16GB and 4x16GB kits aren’t listed.

Hey, G.Skill! We need ECC modules with shiny red heat spreaders for our Ryzen builds!

There's a market for at least four modules!

Why can noone else hit bus speeds over 108?

@djotter Because you need an external clock generator. Buildzoid covered these and stated that currently only a few premium motherboards have that. Don't be scared of the hair (video is informative as always, Ryzen subtimings and so on): https://www.youtube.com/watch?v=frw9HRwqODk

Very informative, thanks for sharing! That hair though hehe.

Fabulous hair for Hardcore overclocking :-)

That external clock gen looks like it will be a exclusive feature for the top motherboards. Only the most expensive boards seems to have it. Looks like it could be important for high performance overclocks too. I wonder if the interconnect fabric can be overclocked.

64GB DIMMs???? I'm thinking minor typo/I read that wrong.

March 8, 2017 | 01:23 PM - Posted by Tim Verry

Hah yeah, typo. The 64GB kit uses 16GB DIMMS

What is Ryzen sweet spot in term of ram speed ?

Any definitive review on this ?

And its confirmed, Windows7 is doing massively better in games with Ryzen then Windows 10... because of thread scheduler differences.

I think someone saw a ~20% boost in some game moving to Windows7.

So if review are redone with the fixed Windows10 and 3200+ ram,
could Ryzen actually BEAT the i7-7700k ?!

its already quicker at some things but in games its 20-30% slower when cpu bound
in total war which is gimped the most by smt 7700k is over 40% quicker in one review

maybe if they can also improve its memory performance at 3200 through tighter sub timings with bios updates it will get close to 7700k ipc but not its clock speeds

changing bus speeds downclocks pci-e, correct?

Thats particularly good news for forthcoming APUs, which use slower system memory for graphics.
