Lexar ARES RGB DDR5: The Complete Guide

Lexar’s launch release named two SKUs, both 32GB (2x16GB) kits: 5600MHz at CL32-36-36-68 priced $139.99, and 6000MHz at CL34-38-38-76 priced $149.99, with a quote from Joey Lopez, Director Brand Marketing 1. An official Lexar page published for IFA 2023 (1 August) added a 6400MHz CL32-38-38-76 option 2; trade press reported a further 7200MHz addition that December, quoting Lexar’s Joey Lopez — by then titled Director of Marketing — on offering “2 new options to our gaming customers” 3. Lexar’s current product page lists 6000, 6400, 6800 and 7200MT/s — the 6800MT/s grade is not announced in any Lexar source checked for this page 4.

Each of Lexar’s three announcements checked for this page frames the same underlying module — aluminum heat spreader, on-die ECC, an onboard power-management IC (PMIC), and Lexar’s own “RGB Sync” lighting-control software — while only the top rated speed changes 1234. Lexar’s November 2024 release introduced a separate, second-generation family — “ARES RGB 2nd Gen DDR5,” rated up to 8000MT/s — alongside a new “THOR RGB DDR5” line; that release does not describe the original ARES RGB DDR5 family this page covers as discontinued or superseded, only as a separate, existing product 5.

Lexar’s product page lists on-die ECC (error correction built into the DRAM die itself, distinct from a motherboard-level ECC feature), an onboard power-management IC, a 288-pin UDIMM interface, and a 0°C–85°C case-operating-temperature rating, alongside the RGB Sync software for lighting control 4. Neither the April 2023 launch release nor the IFA 2023 update describes the heat spreader’s material or thickness in the same detail as the current product page — those two earlier sources focus on speed, latency, capacity and price rather than construction 12.

The original 5600MHz grade from the April 2023 launch release does not appear anywhere on Lexar’s current product page, which starts at 6000MT/s. Lexar’s own sources do not state when or why the 5600MHz kit was dropped — this page reports the absence rather than guessing at a reason.

Neither Lexar’s April 2023 launch release, its IFA 2023 update, the December 2023 trade-press report on the 7200MT/s addition, nor the current product page states which company supplies the DRAM dies inside ARES RGB DDR5 1234. Lexar’s November 2024 release does name a supplier for a related family, describing the separate ARES RGB 2nd Gen line as using “Premium SK hynix DRAM chips” 5 — but that statement is specific to the 2nd Gen product and is not repeated anywhere on the original ARES RGB DDR5 sources checked for this page, so it is not carried over here.

Lexar’s launch release states the two original kits ship with “quick CL32-36-36-68 / CL34-38-38-76 timings (XMP 3.0 & EXPO™)” and describes the family as designed for “the latest Intel® XMP 3.0 and AMD EXPO™” — dual support from day one, not a feature added later 1. The current product page repeats the same dual-standard claim 4; neither the IFA 2023 update nor the December 2023 trade-press report on the 7200MT/s addition restates it, but neither contradicts it either 23.

Four different prices across three Lexar-linked sources, none restated on the current product page: $139.99 for the original 5600MHz kit and $149.99 for 6000MHz at the April 2023 launch 1; $124.99 for the 6400MHz kit added that August — cheaper than either original SKU, despite being faster than one of them — stated directly on Lexar’s own IFA 2023 page 2; and $139.99 for the 7200MHz kit per trade press quoting Lexar in December 2023 3. Lexar’s own IFA 2023 update states no price for 6800MT/s, since that grade is not announced in any Lexar source checked for this page, and the current product page lists no price for any of the four speeds it currently sells 4.

This page reports only Lexar’s own published specification claims; it does not independently re-run or cite third-party benchmark-suite results for ARES RGB DDR5. Because the family’s rated speed has changed four times across the sources checked here (5600/6000 at launch, +6400 at IFA, +7200 in trade press, and an unannounced 6800 on the current product page), a buyer comparing benchmark reviews of this family should first confirm which specific SKU and date a given review covers. Lexar’s warranty policy defines “limited lifetime warranty” as repair, replacement or refund “if quality problems arise during the use of the product” — excluding shipping costs, misuse, unauthorized repairs and data loss, and requiring an RMA number plus proof of purchase to claim 6.

Lexar’s November 2024 release positions ARES RGB 2nd Gen and THOR RGB as new, separate additions to its gaming memory lineup rather than as direct replacements for ARES RGB DDR5 — the release names both new families without stating that the original ARES RGB DDR5 line is discontinued 5. Lexar also sells a plain, non-RGB “ARES DDR5 OC” line and an all-DDR4 “ARES” family; none of the sources checked for this page covers either in enough detail to compare them directly, so this page does not attempt a full family tree beyond what its own sources state.

Comparing Lexar’s April 2023 launch release directly against its current product page: the launch release names 5600MHz as one of exactly two SKUs at release, priced $10 below the 6000MHz kit 1; the current product page lists 6000, 6400, 6800 and 7200MT/s with no 5600MHz option anywhere 4. Neither Lexar’s IFA 2023 update nor the December 2023 trade-press report on the 7200MT/s addition mentions discontinuing 5600MHz either — it simply stops appearing 23. This is the same kind of gap this site has flagged on other brands’ pages: a SKU quietly present at launch and quietly absent later, with no announcement marking the change in either direction.
