3 (3 banks of 1) This indicates that there are 3 memory slots. These are divided into 3 banks, and each bank consists of one memory slot. Station casino. So you can add memory one piece at a time for the system to use. 4 (2 banks of 2) This indicates that there are 4 memory slots. It'll still support dual channel memory at 128-bits wide, but it might not support bank interleaving which may slow overall performance by 3% to 5%. Dual Channel with Bank Interleaving is best, using all four DIMM slots with a slight bump in VDIMM Voltage for stability. Last edited by wan-clan.org Gordy Freeman; Oct 11, 2016 @ 12:16am #4.
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!
- The Max memory this system can support is 8Gig using Two 4Gig memory modules (1 per slot), You'll need to return your 8Gig module and get two 4Gig modules. Was this answer helpful?
- That would be 4 sticks with 8GB capacity and 3200 clock speed. It looks like the general consensus here is that I am better off to fill all 4 slots. That is odd because I thought I read somewhere.

According to Everymac.com, your 'official' max is 16GB, however you can go all the way up to 32GB. I personally used Crucial memory modules in my iMac and MacBook Pro with no problems. I would go with 2 16GB kits (a 'kit' being 2 8GB modules) for a total of 32 GB RAM (a total of 4 8GB RAM modules).
Can I Fill All Four Ram Slots Slot
Slots
This is the total number of memory upgrade slots (sockets) followed by their configuration. Banks are the way a system addresses memory. A bank must be completely filled with memory modules of the same size and type in order for the system to recognize and address the memory. i.e. :
3 (3 banks of 1) This indicates that there are 3 memory slots. These are divided into 3 banks, and each bank consists of one memory slot. So you can add memory one piece at a time for the system to use.
4 (2 banks of 2) This indicates that there are 4 memory slots. These are divided into 2 banks, and each bank consists of two memory slots. So you must add memory two pieces at a time (they must be the same size and type of memory) in order for the system to benefit from the upgrade.

12 (3 banks of 4) This indicates that there are 12 memory slots. These are divided into 3 banks, and each bank consists of four memory slots. So you must add memory four pieces at a time (and they must be the same size and type of memory) in order for the system to benefit from the upgrade.
