Everything that’s old is new again as G.Skill exploits its inventory of Samsung’s discontinued B-Die with an upcoming DDR4-4000 kit. Compatible with both 9th Generation Intel Core unlocked processors and third-gen AMD Ryzen CPUs, the new model shaves two cycles of latency off the firm’s previous best-rated DDR4-4000 kit.

Part number F4-4000C15Q-32GTRG will be approved for specific motherboards that have been verified compatible with its settings, but the list should be lengthy since so many boards now support DDR4-4000.

G.Skill isn’t the only firm leveraging old inventory to produce new performance highs, as one of its competitors is now using outdated 4Gb ICs to bring dual-rank performance to 8GB DIMMs for the value side of the enthusiast market (review coming soon). G.Skill goes a bit further, using the old DDR3-level 1.50V to get its new XMP / old IC modules to support ultra-tight 15-16-16-36 CL timings in a 4x 8GB kit. And no value-oriented kit will touch the ~60 GBps G.Skill has discovered across a mere two channels, so we expect you'll be asked to pay a premium when this kit launches later this quarter.

    I just picked up another set of Flarex to get 32 GB(Samsung b-die). It's just too cheap at $120 for 16 GB. Plus i'll take the extra 6-7% extra performance boost of running two ranks of memory per channel that you typically get from Ryzen. It's a good time to snag B-die before it's gone.

    I really never cared about B-Die before it was discontinued, because I saw 1.50V as a big step backwards and Hynix had ICs that would beat B-Die at 1.35V. But you guys, the one point fivers, I get it, so go for it ;)

    The sweet spot is 3600, and tight timings are worth $$$ but 4000, 5000 etc is a waste of money
