G.Skill will soon be upgrading its Trident Z RGB line of DDR4 DIMMs with a 16 GB kit capable of running at 4700 MHz. With the claimed fastest commercial kit of RGB-equipped memory modules, the new 2 x 8 GB kit uses Samsung B-die ICs and supports XMP 2.0 memory profiles. The super-fast memory kit has been in development for quite a while and is slated for availability in Q2 2018.

G.Skill has managed to tighten the timings on its 4700 MHz kit to CL19-19-19-39 while needing only 1.45V which is nice to see. The company has reportedly validated the new memory using a MSI Z370 Gaming Pro Carbon AC motherboard and Intel i7 8700k processor. G.Skill notes that the new kit is notable because it is the first retail kit to hit 4700 MHz as well as the first memory kit with RGB LEDs to hit that lofty memory speed. Corsair comes close at 4600 MHz with its 16 GB Vengeance LPX DDR4 kit at 15-15-15-36 which will set you back a cool $589.99 MSRP.

I am curious on the overclocking headroom on these modules actually (heh). G.Skill is reportedly using highly screened B-dies so maybe the 5,000 MHz its other kits have hit (when overclocked) would be possible. I would like to see AMD’s Infinity Fabric performance at that point when it is not being held back by memory speed especially where its upcoming APUs are concerned. On the Intel side of things, I think tighter timings are preferrable (after a certain threshold of acceptable speed of course) when pursuing the best performance so a "slower" 3600 to 4600 MHz kit at CL15 or lower might be a better buy. In any case, memory continues to be pricey, and I would uess G.Skill's new kit will hit at least $600 MSRP.

G.Skill is not yet talking pricing on these modules, but they aren’t going to be cheap. We should know more in a couple of months as we enter the second quarter.

Their 4600MHz kits are $25/GB https://www.newegg.com/Product/Product.aspx?Item=N82E16820232628
so I guess these will be a bit more. Not worth it unless you're trying for record benchmark scores. At least G.Skill has better prices than Corsair.

"I would like to see AMD’s Infinity Fabric performance at that point when it is not being held back by memory speed especially where its upcoming APUs are concerned"

Well for AMD's Discrete Vega GPUs that Infinity fabric is not tied to the memory clocks for very good reasons. AMD needs to get some better cross clock domain tweaking done without adversely affacting memory latency on its CPU and APU SKUs so those memory clocks are not such a limiting factor on AMD Zen Micro-Arch/Infinity Fabric based CPUs and APUs.

The best thing that AMD can do for Raven Ridge APUs is to get some HBM2 included or even some on die eDRAM sorts of memory for both the CPU cores and the GPU cores to share and that will help even more to reduce dependencies on slower system memory. Hell AMD that's the next evolutionary step for APUs to get at least 1GB to 2GB of HBM2 that the APUs CPU and GPU cores can share along with the Infinity Fabric clocks decoupled from the main memory clocks.

L2 cache can be increased for CPUs and GPUs also at 7nm.
One thing good about the IF is that it's scalable both the Data fabric part and the Control fabric part. But yes the Infinity Fabric needs to have its very own clock domain not tied to system DIMM based DRAM clock speeds or even HBM2 clock speeds.

I'd like to see companies stop focusing on high prices needlesly fast kits and instead do something about the ridiculous and unjustified prices that currently exist. Shortages my ass, there is no shortage of stock on retail shelves.

Everybody hold on to your smartphones and do not upgrade so often! That will reduce the demand for DRAM and hit Samsung/the other 2 of the big 3 DRAM makers in their wallets.

Keep those smartphones longer and put off updating that smartphone hardware and let the Smartphone makers suffer also, until they get the price of PC/Laptop DRAM down to resonable levels.

This will also work for NAND pricing and that will get some attention for those DRAM/NAND makers.

Gamers and PC buliders/laptop owners, would you rather have lower cost DRAM or a new smartphone every year! Hit them right in their demand curve and that will bring down pricing.

They will have no "Fab Capacity" excuses if demand falls for smartphones and the DRAM/NAND makers try and reduce production further. They will get in trouble with the Regulatory angencies that already have the DRAM/NAND makers in their crosshairs!

Do you really need the latest smartphone or do you want lower DRAM/NAND pricing. hitting them in their wallets hurts more and will really get their attention!

It's time to get all GrassRoots on their A$$ and pass this message along on other Blogs and Forums, Keep your Smartphones Folks for a good few years and DO NOT Update to any new Smartphones until PC/Laptop DRAM prices go down a whole lot!

Heh, thats true....but Apple/Samsung fanboys and fangirls are sheep. Granted I'm likely to upgrade my wife's phone in a few months but its because its damaged.

As much as I'd love a Pixel 2, there is nothing wrong with my Nexus 6P so a week again I had the battery replaced as that was the only problem. The only reason I got the 6P was because my Nexus 5 had a badly ended collision with my kitchen tile.

Human nature being what it is, this won't work - most will figure that, "as long as the others are boycotting, my one little purchase won't hurt anything". It will take a lot more than forums and blogs to get enough people on board. And those who upgrade their smartphone every year are not the most reasonable and sensible people, and few will refrain.

And those people could give 2 craps about RAM prices in computers because it doesn't affect them (although RAM prices are ultimately leading to higher cell phone costs I would suppose but who knows)

Id like to see if the price vs performance makes these even worthwhile

Has PcPer tested the 4600 MHz ram on any video games ?

Intel's new i7-8809G has 4GB's of HBM2 cache for the custom Radeon RX Vega graphics.
