2x8 in quad channel motherboard

 Share

Hi all,

 

About a year ago when I built my PC I was blissfully unaware of single/dual/triple/quad channels. I bought a 2x8 set and installed both sticks next to each other (in the same channel). Today I looked at the manual for the first time and realized I'm getting half the bandwidth I could be getting.

 

The manual wants me to put 1 stick in dimm D1 and 1 in B1. The only problem with that is that A1, A2, B1, and B2 are all blocked by my radiator.

 

My question is; would I get the same dual channel performance if I put the sticks in C1 and D1?

 

My motherboard is ASUS X99-E and my ram is 2x8 Corsair Vengeance DDR4-3000.

just do that, and use CPU-Z to check.

Didn't realize I could do that, thanks!

I figured I'd check once before changing anything, and it already says dual... How is that possible on DIMM D1 and D2?

Check the user manual. They all have a full chart with all possible configurations from 1 up to all 8 populated DIMMs.

The manual only shows the recommended slots for configurations of 1/2/4/6/8 sticks. I have 2 sticks but am asking about unmentioned configuration.

because witch craft?

 

You can also use AIDA64 memory tests, dual channel setups should perform a lot better than single channel

I ended up moving a stick so I'm at C1 and D1. I ordered a new case this morning that'll allow me to front-mount my radiator so this shouldn't be a problem after that gets here. Thanks for your help though!
