can i run these together?

[jrbar89]

finally got my computer up and running and want to know what is the rule of tumb for running two different rams sticks. i got a patriot 1x8gb 1600mz and 2x4gb gskill ripjaws x this was a 16gb set but i only have two.

gskill
DDR3 2133 (PC3 17000)
Timing 11-11-11-30
Cas Latency 11
Voltage 1.6V

patriot
ddr3 12800 pc3 1600mhz
timing 11-11-11-28
cas latency 11
voltage 1.5

Can try the three at 1600, 11-11-11-28, 1.5 - it might or might not gowith the reduced voltage on the 2133 stick it will prob be stable down at 1600, no guarantees, but give it a try

Well you are clearly referring to a triple-channel ram config which not many motherboards are able to support. Also is the gskill at 2133Mhz?

Was thinking dual channel (No mobo listed, majority are Dual), 1600 sticks in 1-2 (from CPU) and the 8GB stick in slot 3 = 8GB in each channel - that's dual channel - if it is a X58 (tri channel then A1 a 4Gb B1 a 4GB and C1 the 8GB, if it does flex then 12GB total in Tri and 4GB in single channel, else run it in the dual channel setup (4gb in A1 and A2, and 8GB in B1)

yes the g skill is at 2133Mhz and the mobo im running is a gigabyte GA 970a-d3 thanks for the replies. with this mobo what config do i use?

The first I suggested - it puts 8GB in each channel so it will hopefully run in dual channel, may need to raise the DRAM voltage to 1.55 and the CPU/NB voltage to 1.2 on your rig
