Pro overclocker pumps G.Skill DDR4 to 5.5 GT/s

When you hear "2750 MHz DDR4 memory" your mind likely auto-corrects to "2750 MT/s." Except in this case, that's wrong. G.Skill sent us a line informing us that professional overclocker (what a job, eh?) Toppc achieved a stunning 5.5 GT/s memory transfer rate using an Intel Core i7-7740K CPU astride an unspecified X299 motherboard. The new record is verified by HWBot and is a 500 MT/s improvement over Toppc's 5 GT/s record from last year.

The memory used by the Taiwanese talent was obviously G.Skill's own, and the company confirmed that the modules in question were assembled using Samsung DRAM ICs. There's no real surprises to be found here; Intel promised that the Core i7-7740K would offer the highest gaming performance possible and as we've come to understand lately, memory performance can be a big part of that.

Achieving that insanely high clock rate required insane cooling—in this case, liquid nitrogen. The achieved result isn't extremely useful in practice, because to hit that high number Toppc had to disable all but one core of the Kaby Lake-X CPU. That isn't unusual for these world-record overclocking attempts, though. The point isn't to create a usable overclock, it's simply to reach the highest number possible.

Clock rates like this won't be coming to mere mortals like you or me anytime soon. You can get pretty close, though. The company announced limited availability of 4800 MT/s kits at Computex. We reckon that ought to offer some pretty solid performance in DayZ.

    It’s interesting that some computer dorks need to be reminded constantly that extreme overclocking isn’t intended for stability but to only achieve, in many instances, a single purpose.

    I wonder if those same, short-sighted, small-minded, ideological simpletons have similar issues with drag racing. power lifting and other activities where people attempt to push limits.

    i’m srs, bros.

      I don’t know that I’d agree. Drag racing is at least viscerally thrilling, and power lifting involves pushing human limits. I’d say overclocking competitions are more like car audio SPL competitions. A tax write-off for the sponsor and fun for the participants, but that’s about it.

      Not dogging on anybody who’s into it. It’s as valid as any other geeky hobby.

    [quote<]Clock rates like this won't be coming to mere mortals like you or me anytime soon. [/quote<] You can say that again. Mature DDR5 might (and this is by no means guaranteed) hit similar speeds eventually in real-life configurations, but it ain't happening for DDR4. LN2 overclocking is an amusing sideshow that's far more entertaining than seeing yet another corporate booth at CES/computex/etc, but it's not really indicative of real products either.

      Chuck spilled the beans on LN2 overlocking. Up until this point I thought a 7 GHz KBL overclock was 24/7 IBT Max stable.

      Thank you for your insight, Chuck “tha S4g3” ula.

      Yall are going to make me uninstall my browser if yall keep it up.

      still srs, bros.

        Look, we all know you’re still upset after receiving the lifetime ban over the incident involving the Dewar flask of liquid He and the karaoke machine.

        But you don’t need to take it out on us.
