I've got an Asus P5B Deluxe motherboard. Today I tried adding some new RAM to take it from 4GB to 8GB. The board is about 6 years' old. I've never used the black RAM slots before, only the yellow ones (2x2GB in slots 1 and 3).
My system only sees 6GB, not 8GB. I've tried various combinations of the RAM, get the same result.
To check the new RAM wasn't defective, I tried it in slot 1, a known good slot. All 4 sticks of RAM worked in slot 1, so the RAM wasn't faulty.
All 4 sticks work in every slot except slot 2 (the first black RAM slot). If I put any stick in slot 2 - old or new - the PC is dead, it won't even boot to the BIOS.
So it looks like I have a defective RAM slot.
Does anyone know of any way to fix this? The board is too old to RMA. I've tried an emery board down the defective slot, and I've tried squirting WD40 down it. No improvement.
Does anyone have any other ideas on how to get that bad slot working?
Thanks!

Motherboard Ram Slots Not Working
On Windows 10, when your computer starts getting slow due to memory demanding applications (such as Google Chrome, Photoshop, or Premiere Pro), understanding the number of RAM (Random Access. SuperUser reader Totymedli is curious about the color coding of RAM slots: I have always seen that the motherboard RAM slots are colored in pairs, but never knew what it meant. I just put the 2 RAM in, and after a few tries it always worked. But after I tried to install a third one it always throws me a blue screen of death. RAM slots on a motherboard come in sets, and it is important to make sure you install RAM in sequence corresponding to these sockets. The RAM fits into long channels on the motherboard in sets of two, three or four. Most motherboards come with built-in functionality for audio, video and networking. If you need additional functionality, motherboards include slots to install expansion cards. The slots on a motherboard are either designed for a specific component, such as memory or storage, or designed for general expansion.
