Specifications of DRAM: DDR4 PC4-19200 ? CL=17 ? Dual Ranked ? x8 based ? Unbuffered ? NON-ECC ? DDR4-2400 ? 1.2V ? 1024Meg x 64Īs mentioned earlier, Crucial motherboard compatibility checker tool says that the module is compatible. Wondering if those could be impacting my Crucial module as well ?Ĭrucial 8GB - DDR4 2400, 1.2V - CL17 UDIMM I've seen some sticky note regarding G.Skill DRAM modules as well. I think the above is an indication of either incompatible DRAM or faulty DRAM. With the DRAM stick removed from motherboard, the EZ debug light for CPU-LED is continuously ON (white) With the DRAM stick in DDR slot-1 the EZ debug lights glow in following repeating pattern: DRAM-LED: 5 seconds, CPU-LED: 1 secondĢ. With that part checked, I started again from basic but made the following observation:ġ. This was done under very good lighting conditions and by turning the motherboard around from various angles. I used a 5x high-quality magnifying glass and also a 20x loupe to scan each pin, literally pin-by-pin and row-by-row. Kindly help.Īfter very careful inspection of the motherboard CPU socket for any bent pins, I am pretty confident that there are no bent pins. Please note that I used anti-static wrist-band, and worked very carefully in a fairly static free environment.

I read around the forum and noticed some suggestion to disassemble the CPU-cooler-fan, CPU itself and inspect the pins carefully to check for any bent pins. CPU and DRAM LEDs, for 1 second each or so. After installing this, when I powered on, the EZ Debug LEDs just get stuck on white LEDs flashing alternately, i.e.

Please note that I've assembled several desktops in the past, so know very well what I am doing. I had the flashing LEDs for CPU and RAM on a MSI B150 PC Mate motherboard. HDD: Seagate SATA 1Tb Barracuda ST1000DM010.CT8G4DFS824A (CL17), which Crucial website stated was compatible with this motherboard CPU: intel i5-8400 with stock heat-sink and cooling-fan.Assembled a brand-new MSI H310M-PRO-VH motherboard today, with all brand-new decent quality parts.
