Engineering Architecture Analysis

Memory Controller Downclocking & Speeds

Both memory modules are user-serviceable located beneath a metal electromagnetic shield. Intel 13th Gen H-series processors natively downclock 5600MHz RAM to 5200MHz, so 5600MHz modules will operate stably at 5200MHz CL42.

Supported Memory Speeds:
  • 4800 MHz
  • 5200 MHz
  • 5600 MHz (runs at 5200 MT/s due to CPU memory controller limit)

Rank Density Impact: 1Rx8 or 2Rx8 kits provide 6-10% higher minimum 1% lows than high-density 1Rx16 modules.

How to Install RAM in Lenovo LOQ 15IRH8 (2023-2024)

Mandatory Safety Protocol:

Always disconnect the internal laptop battery cable immediately after removing the bottom panel. Never touch RAM slots or internal motherboard components with the battery energized.

1

1. Power down laptop, disconnect charger, and ground yourself to discharge static electricity.

2

2. Unscrew the 10 Phillips PH00 screws from the underside base panel. Note the different screw lengths.

3

3. Insert a plastic guitar pick along the front seam and slide around the perimeter to release the plastic latches.

4

4. Remove bottom casing. CRITICAL SAFETY STEP: Unplug the internal battery connector from the motherboard before touching any electronics.

5

5. For RAM Upgrade: Gently pry open the metal EMI shielding box. Push the two side retention springs outward to release each SO-DIMM module at a 45-degree angle.

6

6. Insert new DDR5 SO-DIMM modules firmly into slots at 45 degrees, then press down until the side metal tabs click locked.

7

7. For SSD Upgrade: Remove the M.2 retaining screw, slide new single-sided M.2 NVMe SSD into Slot 1 or Slot 2, and fasten the screw snug without over-torquing.

8

8. Reconnect the battery cable, snap the bottom cover into place, and re-tighten the 10 screws.

9

9. First Boot Notice: On initial power-up with new RAM, expect a 45-90 second black screen while UEFI memory training executes. Do not interrupt or power off.

Looking for Storage & M.2 SSD Upgrades?

Inspect underside M.2 clearance limits (≤2.38mm), secondary slot form factors, and avoid double-sided NAND clearance traps.
