G.SKILL Hits 4500MHz With All-New Trident Z DDR4-4333MHz 16GB Memory Kit (betanews.com)
BrianFagioli quotes a report from BetaNews: G.SKILL is a respected RAM maker, and the company is constantly pushing the envelope. Today, it announced a new DDR4-4333MHz 16GB Memory Kit (2x8GB) -- the first ever. While that alone is very cool, the company is bragging about what it accomplished with it -- an overclock that hit 4500MHz using an Intel Core i5-7600K processor paired with an ASUS ROG Maximus IX Apex motherboard. Pricing and availability for this kit is unknown at this time. With that said, it will probably be quite expensive. What we do know, however, its that the insane overclock to 4500MHz is for real. This was achieved using timings of CL19-19-19-39 in dual channel, which resulted in read/write of 55/65GB/s and copy speed of 52GB/s.
I had no idea.
Also that's some criminally fast memory, shame they are only 8GB sticks and shame it's about 70% more expensive than it was 7 months ago.
I'm literally not upgrading anything due to this, I can take 20% but this has become ridiculous. Count me out of the upgrade game.
Why does this have an AMD tag on it. It's an i5.

Back in the old days, RAM was clocked at the same speed as the CPU, so RAM could be accessed with a minimum of wait cycles. Then speeds diverged, making various levels of cache necessary.
Does the advertised 4.2 GHz speed mean we're back to RAM that's synchronized with the CPU? Or is the issue more complex than that? The 19-19-19-39 timing mentioned suggests that it is, but TFA is light on detail.
I've been using G.Skill memory modules in my builds for the last 10+ years. Never had a problem with them.
I'm waiting for the prices on DDR3 memory modules to drop. On a related note, prices on DDR2 memory modules have dropped since the introduction of DDR4 memory modules. Hmm...
Hence, Apple is not a respected computer maker anymore. :)

I bought two dimms and then I bought two more dimms and then my first two dimms BOTH went bad. However, G-Skill replaced them rapidly and graciously with the precise same P/N and I had no downtime, just time with half the RAM. I strongly suggest the same route to others. Buy your second pair of DIMMs later so they may have come from a different batch :)
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
G.Skill does not manufacture the memory dies, it purchases the memory dies and assembles them into a DIMM memory module ready for sale to customers - Wikipedia.
Which means that technically they are assembling memory modules, instead of producing them from start to finish.
There are just four companies in the world which actually produce memory chips and they are: Micron (Crucial), Samsung, Hynix, and Toshiba.

One time I bought two pairs of G.Skill DDR2 memory five years apart. Same part number and specs. Heat sink on the newer pair had a slightly lighter shade of blue than the original pair.
Some games really do benefit from having faster memory. Arma 3 for example, really benefits from higher memory speed; in The Techreport's test, for example, moving from DDR4 2133 RAM to DDR4 3866 RAM increases the fps from 46 to 56. http://techreport.com/review/3... Of course, the DDR4 3000 kit they tested got 54 fps; that is probably about where diminishing returns kick in for most games. Fallout 4 is another game where having faster memory can make a 10-15% difference in certain areas.
I recently built a new computer, something I don't do very often (every 5 years~ and I got lazy last time and got a prebuilt, so it's been a while).
First, RAM speed barely makes a difference for most people since not everyone is editing videos all day (and in games it barely does anything).
Then, these kits only reach these speeds with the timings properly setup, on the right motherboards/cpu combo (even if all your hardware is advertised as being compatible with the speeds). Often only if you only use 2 chips (at 4 its a coin toss if it will reach it or not). And even with all that, it's still a lottery if the ones you got will reach it and then you have to decide if you care enough to play the RMA lottery.
There were huge gains in Core i3 6100 tests, the particularity being it applies to many games there. i3 are not overclockable but have a high clock in the first place. Save for one recent model which is overclockable but costs the same as an i5.
The only annoying thing, with Intel, is that you need a motherboard with Z170 or Z270 chipset to clock the RAM higher. So, they make it harder to max out single thread performance on a cheap budget. i3 7100, DDR4 2400 (up from the older 2133 limit) and B250 motherboard will be a relatively cheap option to play ARMA 3 specifically and emulators, but leaves some performance on the table.
Wake me up when RAM speed has any noticeable effect on real world performance.
Besides,all they're doing to get this, is overclocking standard slower speed memory on a tester then binning the individual chips accordingly. You aren't getting RAM that was actually made to go this fast, whcih brings a LOT of reliability questions up.
Personally I'd rather have good reliability than a slightly higher score on benchmarks that you'll never notice in real life.
There's been several videos/articles showing Ryzen (their new CPU) closing it's gaps with Intel when RAM was overclocked; even if you run the same overclock on Intel hardware.
