Solved!

Upgraded to 32GB RAM with XMP but keep getting random crahses and mem test fails

Hello Everyone,

 

I have an issue with my laptop after upgrading the default 16GB RAM to 32GB.

 

The modules I upgraded to are 2 x HyperX Impact DDR4 16GB, 2666MHz CL15 SODIMM XMP

 

When I use both modules together, the PC is highly unstable. I get random crashes and the memory test (from the BIOS) fails within 5 seconds. When I use just one module, everything works well (1 x 16GB). When I use the 16GB module with 1x 8GB again, everything works well. The problem reoccurs when I use both 16GB modules.

I had the modules tested in another laptop for 3 days and they worked well with no issue. Also, Memtest was used on the other laptop for around 12 hours on a loop and no errors occurred.

 

What I have noticed from my testing and monitoring for changes is that the newly bought RAM support XMP and RUN at a CL of 15 whereas the original modules run at a CL 15.

 

This is the profile of the XMP for the 16GB Modules (Module Name Kingston HyperX KHX2666C15S4/16G): @ 1333 MHz 15-17-17-35 (CL-RCD-RP-RAS) / 60-467-347-214-7-7-7-30 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-CCDL-FAW)

This is the profile for the 8GB (Default) Modules: @ 1333 MHz 19-19-19-43 (CL-RCD-RP-RAS) / 61-467-347-214-7-4-7-28 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-CCDL-FAW)

 

Both default modules and upgrade modules run at the same speed of 2666Mhz with the difference in the timings.

 

Note: when the 16GB module is used with an 8GB module, the default timings are applied to both chips.

 

Note 2: When I say default I am referring to the modules that came installed with the purchased laptop (Module Name SK hynix HMA81GS6JJR8N-VK)

 

I am using the latest bios Version 25.A.

 

Is there someone else with the same issues or something that I can try?

 

I've spoken to support through chat but since this is not a warranty thing nothing can be done, so a gaming laptop is useless when paired with "gaming" RAM modules.

 

Please refer to the attached screenshots for all the specs.

Thank you for your help,

So this is something that can be fixed by a bios update whereby allowing to disable XMP and use safe timings if HP care to look into the issue that is.

The simple answer is 2 x HyperX Impact DDR4 16GB, 2666MHz CL15 SODIMM XMP is NOT compatible. My machine uses Samsung RAM
