How to test and safely keep using your janky RAM without compromising stability using memtest86+ and the memmap kernel param.

I'm thinking my G.Skill 64GB set I bought in 2025 is crashing my PC. Gonna run a MemTest86+ overnight to check. Rated for 1.45V and up to DDR4-3200 with the XMP profile- PC crashes under load just minutes into a fresh reboot.

This said, an equivalent 64GB kit of their DDR4 CL19 (F4-2666C19D-64GVK) is retailing at the store I bought my original CL14 Ripjaws for €753. I bought the CL14 faster 64GB kit (F4-3200C14D-64GVK (EOL)) for €177.45 So SHIT I don't know how G.Skill is going to handle my situation, if MemTest86+ fails out at the 3200MHz stress test (on their official site, they declare that my possibly defective F4-3200C14D-64GVK (EOL) can reach 3200MHz with a small bump up of voltage to 1.45V, up from stock 1.2V).

How did it play out for you, with their Limited Lifetime Warranty? I'm in the EU.

    I'm in the States but they were great about it. Issued an RMA and sent me new RAM. Total turnaround from me shipping bad ram to receiving new was only about a week. I haven't tested the new RAM yet but assume it will be fine. I couldn't ask for a much better process to be honest

    Thanks so much for the swift reply! Reassuring. I'll be devastated that I'm going from CL14 3200Mhz to CL19 2666Mhz if they want to "upgrade" me. I did a lotta research when piecing my build, and the AMD 5950X has an Infinity Fabric of 1:1 at CL14 3200Mhz. I wanted the absolute best baseline, GPU-excepted. Sowing down ain't for this build.

    What state if you don't mind me asking? I lived in FL, TX, MD, and PA before jumping The Atlantic Ocean a few years ago.

    I'm over on the other side of the states in the PNW. Also running a 5950x! We're computer twinsies

    I did a huge jump from an AMD Phenom II X6 1055T CPU (6-core AM3 socket) kept in an old gen1 Thermaltake Armor case (think plastic transparent window), my 2012 build. This is my 3rd build ever, and the Thermaltake Armor had to go! I love this 5950x, it's a beast, and I hope to get 10+ years outta this rig. You?
