Transcend JetRam DDR5: The Complete Guide

Two Transcend product sheets exist under file names ending 2207 and 202407; neither prints a date 21. The 2207 sheet lists six DDR5-4800 parts from 8GB to 32GB 2. The 202407 sheet keeps those six and adds ten DDR5-5600 parts, taking capacities to 48GB 1. No Transcend press release for JetRam DDR5 was found for this guide.

The 5600MT/s page says the modules are “Compliant with JEDEC international standards” 3, and both sheets list the standard as JEDEC 21. None of the four Transcend sources checked mentions Intel XMP or AMD EXPO 2134.

Both sheets give PCB Height as 1.18 inches (262 pin) and 1.23 inches (288 pin), with no millimetre figure or module length 21. The sheets say the modules use a power management IC (PMIC) and on-die ECC at 1.1V 21. Neither the sheets nor the pages describe a heat spreader 2134.

The 5600MT/s page gives organizations (1Gx16)x4 for 8GB, (2Gx8)x8 for 16GB, (3Gx8)x8 for 24GB, (2Gx8)x16 for 32GB and (3Gx8)x16 for 48GB 3. The sheets give an operating temperature of 0°C ~ 85°C 21. No CAS latency appears on either sheet or either page 2134.

The 5600MT/s page says the modules “are manufactured with true ETT grade, brand-name DRAM chips that have passed Transcend’s strict screening process and rigorous environmental testing” 3. The 202407 sheet uses the same wording 1; the 2207 sheet’s version ends “strict screening process and testing” 2. None of the four sources names the chip maker or explains “ETT grade” 2134.

The product pages list Device “Desktop” and type “DDR5 Unbuffered Long-DIMM” 34. The sheets list both Long-DIMM and SO-DIMM modules 21. None of the four sources names a processor, chipset or motherboard 2134.

Neither product sheet nor either product page states a price or a recommended price 2134.

The 2207 sheet’s headings are “Ultra Fast!”, “Dual Transfer Channels” and “Optimized Power Efficiency” 2. Neither the sheets nor the pages state a warranty period 2134. Transcend’s US warranty page describes both a specified warranty period and a “limited Lifetime Warranty Service” in general terms, does not say which applies to JetRam DDR5, and says “Memory module kits must be returned as a complete set.” 5

The 2207 sheet lists only DDR5-4800 2. The 202407 sheet adds DDR5-5600 and the 24GB and 48GB sizes built from (3Gx8) organizations 13. The German 4800MT/s page lists three long-DIMM parts, matching the sheets 41. None of the Transcend sources checked mentions a faster grade or a successor 2134.

The sheets have columns for Standard, Frequency, Capacity, Voltage, Pin Count, PCB Height, Operating Temperature, Component Composition and Rank x Org, and no column for latency 21. The 2207 sheet also carries a sentence about a different line, “Transcend’s Standard memory modules are manufactured with Major-grade, branded DRAM chips” that passed “rigorous environmental testing”, next to the JetRam sentence ending “strict screening process and testing” 2. The 202407 sheet drops the Standard sentence and gives JetRam the “rigorous environmental testing” wording 1. Neither sheet names the chips or defines either grade 21.
