Defective Ram Slot

You can go into your File Explorer, right-click on your hard drive or SSD and click “Properties.”. Under the “Tools” tab, you’ll see an error-checking option. Click on the “Check” button and Windows will begin checking for error. Alternatively, you can open command prompt and type in the command “chkdsk.”. If your computer has only one RAM stick or module then you can easily identify it. But when you have multiple RAM modules installed then you can check the faulty RAM by plugging in the RAM module one by one and testing each one of them individually. The faulty RAM module will likely to cause one or more problems mentioned above.

Faulty Ram Slot

Hi All - this is my first time posting here and glad to come across such a vibrant and engaged community! So I embarked on a journey to finally upgrade my 10 year old NAS system running ubuntu with FreeNAS!
My hardware specs are below:
RAM - 2X MEM-DR380L-HL02-EU16
Mobo - X10SAE with latest bios
CPU - Xeon® E3-1265L
I finally had a chance to put the system together last night but unfortunately I was greeted with four long beeps and no post upon powering up. This was following Supermicro's recommendation of populating the blue RAM slots. Further reading only revealed that it might be a RAM problem so I started testing the RAM one stick at a time, starting from the RAM slot farthest again from the CPU. The motherboard will not post when RAM is installed in slot DIMMA1 and DIMMA1 (two slots closest to CPU) but works fine with with slots DIMMB1 and DIMMB2 populated. I've been running memest86 in this configuration for the past 24 hours to see if there are any issues.
Could it be that the RAM slot is defective? The seller is sending me a replacement board ASAP so hopefully the replacement board works fine :)
