G.Skill offers up hexa-channel RAM at up to 4 GT/s

One of the nifty things about the Intel Xeon W-3175X is that you could feasibly stuff 768GB of RAM into a system built around it. Such extravagant RAM is mostly wasted on the kind of users that chip is meant for, though. Registered memory likely leaves a lot of performance on the table, too. Instead, we think most users would be better served by something like one of G.Skill's new hexa-channel memory kits.

These kits are part of G.Skill's Trident Z Royal line, so if you're allergic to bling, you're out of luck. Transfer rates on the new RAM range from 3200 MT/s to 4000 MT/s, and you can take your pick of 8- or 16-GB modules in packs of six or twelve sticks. The 3200 MT/s memory comes in two variations: one with fairly-standard 16-18-18-38 timings, and another with very tight 14-14-14-34 timings. Meanwhile, the 3600 and 4000 kits run a little looser at CAS 17, although that should still put their latency in the same ballpark as the lower-throughput modules.

It's a little curious to see G.Skill offering so many different configurations for a product that will surely be produced in infinitesimal quantities. The only processor that can realistically make use of these kits is the just-launched Xeon W-3175X, and that chip is only going to be available from system integrators in frightfully small numbers (for terrifyingly large dollar amounts.) That's probably why G.Skill doesn't offer any pricing information for the new RAM. Still, G.Skill says the memory will be available from its distribution partners, so we suppose we might see it in shops.

    Those are some nifty CAS latencies. I reckon even much slower vanilla DDR4-2400 sticks are CL17.

    This may be a dumb question, but I’ve never understood the marketing behind dual/quad/hexa-channel kits.

    If I buy an hexa-channel kit of 12x DDR4-4000 DIMMS with 17-18-18-38 timings at 1.35V, how exactly is it [i<]any different at all[/i<] to buying three dual-channel kits of 4x DDR4-4000 DIMMS with 17-18-18-38 timings at 1.35V? Hell, the thing that matters is the timing and voltage. If it doesn't meet those quoted timings at that voltage, it's being mis-sold under false advertising. Whether a CPU's IMC can drive twelve DIMMS at those quoted timings and voltages is down to the CPU silicon lottery, and has nothing to do with the marketing label on the DIMMs.

    Yeah, no word on pricing because at current memory prices any of these 16GBx12 piece sets probably cost >= Xeon W-3175X.

    Actually, memory prices must be coming down some, just checked on newegg and this 16GBx8 piece is reasonably priced compared to a few months ago… maybe the memory bubble has burst.

    Meh. Only 192GB of RAM.

      I don’t get out of bed for less than 256GB…

    Yo dawg I heard you need memory bandwidth…..
