1.【DRAM】How do I check if my RAM is bad?+
Use these tools to test RAM:
- Windows Memory Diagnostic (built-in)
- Search “Windows Memory Diagnostic” in Start → click “Restart now and check for problems”
MemTest86 (advanced)
- Download from https://www.memtest86.com/
- Create a bootable USB drive ➡︎ run a full test
⚠️ Tip: Test one RAM stick at a time to isolate issues more easily.
2.【DRAM】What are RAM “gold fingers”?+
“Gold fingers” are the shiny contact pins at the bottom of your RAM stick.
They connect your RAM to the motherboard for power and data transfer.
----------------------------------------------------------------------------------------------
⚠️ Tips:
- Avoid touching them—oil and static can cause problems.
- Clean gently with an eraser if they look dirty or oxidized.
- Damaged pins may cause boot failure.
3.【DRAM】What is dual-channel RAM? How do I enable it?+
Dual-channel lets two RAM sticks work together for faster performance.
To enable it:
- Use two identical sticks (same size, speed, brand is best)
- Install them in the correct slots (usually color-coded on your motherboard)
4.【DRAM】What is RAM CL or CAS Latency? Is a lower number better?+
CL (CAS Latency) = the delay between your CPU asking for data and the RAM delivering it.
- A lower CL is better, but only when paired with a high MHz speed.
- Performance depends on both speed and latency.
5.【DRAM】Can I use RAM from different brands or sizes together?+
Technically yes, but it’s not recommended.
- Mismatched RAM may cause crashes, slower performance, or failure to boot.
- For best stability, use the same brand, size, and speed in all slots.
6.【DRAM】How do I install RAM correctly? (RAM installation guide)+
【1】Shut down and unplug the power: This prevents static damage.
【2】Line up the notch: RAM sticks have a notch—make sure it aligns with the slot.
【3】Press down firmly: Push straight down until both side clips snap into place.
【4】Don’t touch the gold contacts: These are called “gold fingers.” Keep them clean. Use an eraser to gently clean if dirty.
7.【DRAM】Can I mix DDR3, DDR4, and DDR5 RAM?+
No. Each type of RAM (DDR3, DDR4, DDR5) has different pin layouts and notch positions. They’re not physically compatible.
- Mixing types is not possible.
- For safety, never force RAM into the wrong slot—it can damage your motherboard or RAM.
⚠️Check compatibility: Search your device model online to see what RAM it supports.
8.【DRAM】Why is my RAM not running at standard speed ?+
The speed shown on the packaging represents the maximum frequency the memory can achieve on a compatible standard test platform.
In everyday use, the actual speed may vary due to factors such as the motherboard, processor, and system settings.
9.【DRAM】Why is only 8GB of my 16GB RAM usable?+
📍Check what’s detected
-
Press
Ctrl + Shift + Esc→ go to Performance > Memory → compare “Installed” and “Available” RAM.
📍Common causes
-
Shared with graphics: If you don’t have a GPU, 1–2GB may be used by integrated graphics.
-
Outdated BIOS: Update from your motherboard brand’s website.
-
Windows limit: Type
msconfig→ Boot > Advanced Options → uncheck “Maximum memory.” -
Motherboard limit: Check your board’s max RAM per slot and total support.
-
Loose or faulty RAM: Reseat and test one stick at a time.
10.【DRAM】Why won’t my PC boot after I installed RAM? Why is it beeping?+
This usually means the RAM isn't seated properly or is incompatible. Try these steps:
- Reinstall the RAM: Power off, unplug, and firmly reseat the RAM until the clips click.
- Test one stick at a time: Check each stick individually to find a faulty one.
- Check compatibility: Make sure the RAM type and speed match your motherboard.
- Clear CMOS: Reset BIOS by removing the battery for 1 minute, then reinstall.
- Update BIOS: Visit your motherboard brand’s website for the latest update.
