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!
Check Ram Slot Available Slot
I'm trying to find out if my Aspire E15 (E5-521G-632L) has two memory slots so I could upgrade my memory by just adding 2MB so it'll be 6MB RAM after. I've seen 1 of 2 slots used in Task ManagerPerformanceMemory but I heard that's not accurate as most are just virtual memory slot and not actual physical slot in the laptop. Check RAM slot number via Task Manager (Only available in Windows 10 and 8) In Windows 8 and 10, there is a straightforward way to check the number of RAM slots, which is not available in Windows 7. You just need to check it on the Task Manager instead of checking on the Internet or downloading a third-party utility. Check your iPad's RAM usage. The blue, red, green, and grey bar near the bottom of the screen shows the allocation of your iPad's in-use RAM, permanently in-use RAM, free RAM, and system-use RAM respectively. You can also see the actual percentages of your iPad's RAM use on the right side of the screen.
