R510 memory issue

Hardware Enterprise Gear

I just aquired a Dell R510 with dual X5670

I also got 8 stick of RAM
(4x) DDR3 RDIMM 4GB 1RX4 PN: M393B5270CH0-YH9
(4X) DDR3 RDIMM 4GB 2RX4 PN: M393B5170FH0-YH9

As far as i know they have the same spec expect the number of memory rank
The R510 seem to have a weird memory config with 2 bank separated in 3 channel.

BANK1 (slot 1 2 3) BANK2 (slot 4)
Channel 0 (slot1) (slot4)
channel 1 (slot2)
channel 2 (slot3)

Im planning to run this mess in Optimizer mode.
Any idea how i can populate all the slot with my current memory without getting
a geometry of a unsupported dimm error?

Or i just need to get 4 more stick of one or the other mem config?

You should be able to run one type in slot 1 and 2 then one of the other type in slot 4. If you still need the other 8GB you could just get 2 more sticks of the type that is in slot 1 and 2 and populate slot 3.

Thanks you for your reply . At least i know i"m not crazy. now but the manual say you can mix them up.

I will just get 8 stick of the same its not like that stuff is super expansive.
