Everything that’s old is new again as G.Skill exploits its inventory of Samsung’s discontinued B-Die (opens in new tab) 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 (opens in new tab)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isn’t the only firm leveraging old inventory to produce new performance highs, as one of its competitors is now using outdated 4Gb ICs to bring dual-rank performance to 8GB DIMMs for the value side of the enthusiast market (review coming soon).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 (opens in new tab) 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
