I have the same question Report abuse. Details required :. Then, give it a firm downward push, just to be sure. The RAM slot has two plastic wings that should snap over the sides of each stick of memory.

The pins and the slot on the processor and motherboard must be properly lined up. Motherboards are filled with capacitors and soldered connections that route data and power from one part of the board to another.

These exist because the motherboard can short if it makes contact with other metallic components — causing the capacitors to blow out, bulge, and even leak fluid — which makes performing a physical inspection of components crucial to diagnosing issues. However, unless you are extremely confident with your skills with a soldering gun, replacing your capacitors is best left to professionals.

A failure to pass the POST process is the most frequent symptom, but other situations can occur even if only occasional contact is made between the motherboard and the case.

Examine how your motherboard is installed. Try shutting the computer down and installing the second RAM module along with the first one. You can take the information provided by the System Scanner tool and purchase your new RAM from your retailer of choice or simply purchase it directly from Crucial. I sent the two 8GB sticks back and ordered two new 4GB sticks in their place.

Thanks for your help in figuring out what the problem was. I really appreciate the work you do on your site! Ericloewe said:. If that's the problem, it's the single craziest memory problem I've seen in my life. Sure, 2 DIMMs are recommended, for performance reasons, but not booting with just one? Silly question only because it's happened to me : Is the CPU power connector plugged-in? It's not optional. No point in trying without any RAM installed, either.

One thing I didn't notice before is that the PSU fan doesn't spin when hooked up to the motherboard it was mounted in the case, so I didn't see it. Still same results. And none of the ethernet LEDs on the back light up. Of course, this isn't surprising now that I learned the PSU is not being activated. Given that I can get the PSU to work with a paper clip, I don't see any other explanations than that the motherboard is bad.

Any suggestions other than RMA the motherboard? Do you have a known good and functional powersupply you can switch out to verify its either the psu or motherboard? The paperclip test doesn't test under load. So it's hard to rule out the PSU. My first step--given that the supermicro guys say 1-stick should work--would be to use the PSU in a known-good computer to rule out a PSU problem.
