G.Skill Launches DDR5-8000 CL38 48GB Memory Kit For Raptor Lake CPUsby Zhiye Liu on March 13, 2023 4:00 PM EST
G.Skill has announced a new, high capacity DDR5 memory kit for Intel's 13th Generation Raptor Lake processors and accompanying LGA1700 platform. The Trident Z5 RGB DDR5-8000 CL38, which features a capacity of 48 GB (2 x 24 GB), comes with an Intel XMP 3.0 profile for a fast and effortless setup on high-end systems that can accomodate the high-speed hardware
With the release of 24 Gbit DDR5 memory chips, memory manufacturers are working to fill in the gap between current 16 GB and 32 GB UDIMMs. As these new, higher capacity dies allow for larger single-rank DIMMs, this is allowing DIMM vendors such as G.Skill to launch higher capacity versions of their fastest DIMMs.
The memory timings on the Trident Z5 RGB DDR5-8000 aren't great, but they're decent enough. G.Skill binned the memory for CL 38-48-48-127 and 1.45 volts on the DRAM side. The specifications are almost identical to the Trident Z5 RGB 32 GB (2 x 16 GB) memory kits that G.Skill announced a few months back. The principal difference is that the vendor has bumped the memory kit capacity from 32 GB to 48 GB. Unfortunately, G.Skill didn't reveal which DRAM vendor's chips they're utilizing in the Trident Z5 RGB DDR5-8000 memory kit. Considering the data rate, it's plausibly using SK hynix's latest A-die ICs, as many vendors are utilizing those for premium memory kits DDR5-7000 speeds.
|G.SKill Trident Z5 Series DDR5 UDIMM Memory Specifications|
|DDR5-8000||38-48-48-127||1.45v||48 GB (2 x 24 GB)
32 GB (2 x 16 GB)
Meanwhile, it's worth noting that although the Trident Z5 RGB DDR5-8000 has XMP 3.0 support, the memory kit won't quite be plug-and-play on many LGA1700 motherboards. Consumers need to own a processor with a very strong IMC that can tolerate high-speed memory (i.e. top-tier Raptor Lake chips). An equally capable motherboard is required as well. Even then, judging from G.Skill's validation list, it sounds like 1 DPC motherboards are going to be the prime choice. G.Skill has only validated the memory kit on Asus' ROG Maximus Z790 Apex and EVGA's Z790 Dark K|NGP|N, two over-engineered motherboards tailored to extreme overclocking. Interestingly, Gigabyte's Z790 Aorus Tachyon isn't on the list, nor is MSI's MEG Z690 Unify-X.
G.Skill's Trident Z5 RGB DDR5-8000 memory kit is scheduled to hit retail shelves globally in April of this year, going up against as-of-yet-released kits from TeamGroup, V-Color, Galax, and Netac. In the meantime, the company is keeping a tight lip on the pricing, preferring to keep the shock factor under wraps for now. Suffice it to say, given the binning required to produce this speed grade of RAM, and the premium pricing of DDR5 overall, we don't expect that the Trident Z5 DDR5-8000 kits will come cheap.

PeachNCream - Monday, March 13, 2023 - linkCompanies can announce as many products as they want, but I think its more important by far to deliver said products for prices that are realistic given the lack of interest by civilization at large when it comes to purchasing parts for a waning desktop form factor at a time when consumer electronics in general aren't landing sales and the industry as a whole is tightening its proverbial belt.
Also numbers on paper are one thing, but how something actually works is another. Benchmarks? Reviews? That would be helpful. Reply
erinadreno - Tuesday, March 14, 2023 - linkConsidering how much they charge for going from 5600 to 6000, I'd say this product is only for those who just shopping by sorting price high to low.
Realistically tho, who would need only this much bandwidth but not more. CPU is not like GPU that needs to constantly stream large chunks of data in and out of the memory. If you need memory bandwidth, it's better to buy quad+ channel cpus. And you'd likely get benefit from having more cores and larger capacity while saving some money. Reply
Silver5urfer - Tuesday, March 14, 2023 - linkHEDT is dead. Mainstream killed it with huge IPC gains and Clock Speeds. Looking at the new Sapphire Rapids XEON W, it is no match for TR Pro which is very old. And moreover the new Xeon W is super expensive, the mobos are as well due to PCIe5.0 and with Zen 4 TR Pro which will be launching probably next year, it won't be cheap either.
So we have to stick with mainstream compute and gain the best performance possible, unfortunately that's the only way if you want latest technology. Otherwise one option is to buy used Xeon old decommissioned ones. Reply
Silver5urfer - Tuesday, March 14, 2023 - linkThis is one of the reason along with LGA1700 engineering failure why I did not bother with the new ADL, RPL. This DIMM kit is too niche, it's more than Royal Elites with 1.5v at 4000MHz C15 kit. Very hard to run on these processors and DDR5 is barely saturated. It is going to take at-least 2-3 more CPU gens to make this technology worth, and mature. So better wait until 2025/26 and then buy the CPU / Mobo for a real overhaul of performance.
Also 1DPC is always the way to go DDR4 or DDR5. Always pick those mobos only. Although Tachyon Z590 is a mess. Only Apex Z590 and Unify were good. Z590 Dark is also a mess, poor 10th gen support, QC etc. Although ASUS is not clean sheet. It has a lot of QC nonsense as well. Reply
Oxford Guy - Tuesday, March 14, 2023 - linkDual rank is faster where it matters with DDR3. I vaguely think that that's the case for DDR4 also.
Is this now different for DDR5? Reply
mode_13h - Tuesday, March 28, 2023 - linkFor DDR5, the fastest (stock) configuration is dual-rank, 1 DIMM per channel.
I've heard that single-rank DIMMs overclock better, which isn't surprising. Reply
Oxford Guy - Tuesday, March 14, 2023 - linkWhat does Intel list as the maximum IMC voltage that is supported by Raptor Lake? I bet it's lower than 1.45. Reply
TresNugget - Thursday, March 16, 2023 - link1.45v is the DRAM VDD/VDDQ voltage provided by the PMIC on the DIMM itself although IMC voltage probably isn't much lower than that on the few chip/board combos that can actually hit 8000. Reply
