Z170A Gaming M5 Debug Code 4C 55 00 19 0 on replacing RAM revisited

After four years with this rig’s flawless performance, last week I purchased G.Skill DDR4 2X 16GB 3600 to replace 2X 8GB 2400 and experienced the identical symptoms as the OP. https://forums.tomshardware.com/thr...herboard-nothing-after.3552186/#post-21454998

What was the disposition? I understood;

1. don’t use the MSI Command Center, and;
2. update the bios.

im still stuck with my new RAM only working in slots 3&4... NOT in 2&4 which yields your Debug Code 4C 55 00 19 0 ...actually I’m getting on my Z170a gaming M5 , Od 08 19 00 88 4C 55 00 0d 08 19 00 4C 55 (repeated from jogging video of the code to be sure I got it all)


still working on this but I just noticed topic was closed...thus this “addendum”

Thanks y’all
Chas

Did you do a clear CMOS after switching to the new RAM ?
And by the way, on the GSkill configurator for your motherboard the fastest sticks for 2 x 16 Gb is 2666 MhZ

You are way way outside the recommended specs by GSkill

went by the "book" the MOBO manual which said up to 3600

thanks for the heads up!

Do they give a specific reference and for how much memory and stick size ?
GSkill indicates max 3400 MHz for 2 x 8 Gb (total 16 Gb) kits (they give 2 references ).

,
What do you need ? Speed or more than 16 Gb of RAM ?

More Ram...

pulled the 2x8GB 2400...put back the 2x16GB 3600...neither would boot from Dual channel slots 2&4 (which was the origional config). Now only got post & boot from slots 3&4!

Do they give a specific reference and for how much memory and stick size ?

From the PDF manual pp 15
Memory●

● 4x DDR4 memory slots, support up to 64GB▶ ▶Supports DDR4 3600(OC)/ 3200(OC)/ 3000(OC)/ 2800(OC)/ 2600(OC)/ 2400/ 2133 MHz● ● Dual channel memory architecture● ● Supports ECC, un-buffered memory● ● Supports Intel® Extreme Memory Profile (XMP)
