In the world of desktop PC building, we buy "RAM sticks" (DIMMs). But in the world of Ultrabooks, Tablets, and Industrial Embedded Systems, memory is often soldered directly to the motherboard to save space.
The SK Hynix H5AN8G6NDJR-XNC is one of the most popular chips found in these devices.
It is an 8 Gigabit (1GB) DDR4 SDRAM component. But unlike the chips on your desktop RAM stick, this one is x16 wide. This unique architecture makes it a critical component for repair technicians fixing "Dead RAM" on high-end laptops (like Dell XPS or Lenovo X1 Carbon) and for engineers designing compact embedded boards.
This guide decodes the specs and explains why the "x16" factor changes everything.

1. Decoding the Part Number
SK Hynix part numbers are highly structured. Here is the translation for H5AN8G6NDJR-XNC:
| Code Segment | Meaning | Detail |
|---|---|---|
| H5 | Memory Type | SK Hynix DRAM. |
| AN | Generation | DDR4 (1.2V Operation). |
| 8G | Density | 8 Gigabit. (8Gb / 8 = 1 Gigabyte capacity per chip). |
| 6 | Organization | x16 Bits. (Critical Spec). |
| N | Bank | Non-TSV / Normal. |
| D | Revision | 3rd Gen (D-die). Known for decent performance and compatibility. |
| J | Package | FBGA. (Flip Chip). |
| R | Material | Lead-Free / RoHS. |
| XN | Speed | 3200 Mbps. (DDR4-3200). Latency: 22-22-22. |
| C | Temp | Commercial (0°C to 85°C). |
2. Technical Specs: Why x16 Matters
The "6" in the part number (x16 organization) is the defining feature.
x8 vs. x16
- x8 Chips (Standard): Most desktop DIMMs use x8 chips. To make a 64-bit wide interface (required by the CPU), you need 8 chips ($8 \times 8 = 64$).
- x16 Chips (This Part): Laptop motherboards have limited space. Using x16 chips allows you to create a 64-bit interface with just 4 chips ($16 \times 4 = 64$).
The Benefit: This cuts the board space required for memory in half. This is why you see the H5AN8G6... series soldered onto compact laptops and Single Board Computers (SBCs).
3. Hardware Considerations: FBGA-96
Because this is a x16 chip, it requires more data pins than a standard x8 chip.
- Package: 96-Ball FBGA.
- Ball Map:
- It includes pins for DQ0 through DQ15 (16 Data lines) and LDQS/UDQS (Lower/Upper Data Strobes).
- Incompatibility: You cannot replace this chip with an x8 chip (78-ball). The PCB footprint is physically different.
4. Repair & Sourcing Guide
For Repair Technicians: If a laptop with soldered RAM is beeping an error code or crashing, one of the BGA memory chips may have failed.
- Diagnosis: Use software like MemTest86 to identify the failing address range, then map that to the physical chip on the board.
- Replacement: You need a BGA Rework Station.
- Stencil: Ensure you have a DDR4 x16 / FBGA96 Stencil for reballing or soldering the new chip.
Sourcing Warning: Many chips sold online are "Pulled" (desoldered from dead boards).
- Look for: "New Date Code" or "Cut Tape" packaging to ensure you are buying brand new, oxidation-free chips.
- Check the Speed: Ensure the suffix is -XNC (3200) or faster. Putting a slower chip (e.g., -VKC 2666) into a 3200 system will cause instability or downclock the entire system.
5. Conclusion
The SK Hynix H5AN8G6NDJR-XNC is a vital component for the modern, compact computing world. Its high density (8Gb) and wide interface (x16) allow for powerful performance in a tiny footprint. Whether you are designing a new embedded AI board or rescuing a high-end laptop from the recycling bin, this is the specific silicon you need.

Frequently Asked Questions
1: Is H5AN8G6NDJR-XNC suitable for desktop RAM modules?
No. This is a x16 DDR4 memory chip designed for soldered-down applications, not for standard DIMMs which typically use x8 chips.
2: Can an x8 DDR4 chip replace this x16 chip?
No. x8 and x16 chips have different ball counts, pinouts, and signal routing. They are not physically or electrically interchangeable.
3: What systems commonly use this memory chip?
Ultrabooks, business laptops, tablets, mini PCs, and embedded boards where RAM is soldered directly to the motherboard.
4: Does this chip support DDR4-3200 speeds?
Yes. The -XNC speed grade supports DDR4-3200 (3200 MT/s) under proper motherboard and memory controller conditions.
5: Is this chip still in production?
Availability varies. Some units are new old stock, while others are pulled from used boards. Always verify condition and source when purchasing.
