I’ve been building a “new” computer out of 2022 Rocket Lake parts. No problem with that. It just needs some fan-deployment tweaks and minor refinements and good to go.
I chose to swap the RAM from my old “super-duper” system which had 4×16 64GB of G.SKILL 3200 GTZR RAM — that is, this latter went into the ROCKET. I put 16 GB of 2×8 GTZR into the old system, tested it most of the morning — good to go. I had another set of 2×8 GTZ — same specs otherwise just no glitzy lights. It had been tested, previously was working in the ROCKET.
The old system (KABY LAKE) wouldn’t boot! I had handled the RAM carefully, put them in the system with AC unplugged and all powered down. Nothing could’ve happened, but — who knows?
I did a quick search online — it was Reddit. Big discussion. Then, someone suggested “pull all USB devices — including keyboard and mouse, then try to boot. If it boots, plug the USB plugs back in the sytem.” This apparently worked for the people in the discussion — more than one!
AND! AND! I decided to give it a whirl, because I lost a lot of time today, and didn’t feel like testing individual RAM sticks and slots.
AND? AND? IT FREAKING WORKED!!
ANYBODY HAVE AN IDEA WHAT WAS GOING ON WITH THAT? I’d like to understand how some “quirk” was introduced into my motherboard or system by swapping known-good RAM as I did. I had even cleared the CMOS — had to enter BIOS and set everything back the way it was — before I tried the trick with the USB devices/wires.
Now I’ve got to run MEMTEST86+ to check the 4×8 32GB of RAM now in the Kaby Lake system. I need to get to work on the ROCKET LAKE — this is taking too much of my time!
