I have an ASRock Extreme3 X99 mobo with 1x 8GB 2666MHz DDR4 stick installed
I'm looking to add more RAM, I can afford 2 more sticks of the same but I'm wondering if I can run 3 sticks in the board or would I be best to stick to 2.

Thanks.

looked a bit closer at the manual for my motherboard and I noticed
If only two memory modules are installed in the DDR4 DIMM slots, then Dual
Channel Memory Technology is activated. If three memory modules are ins
talled, then
Triple Channel Memory Technology is activated. If four memory modules are i
nstalled
in the DDR4 DIMM slots, then Quad Channel Memory Technology is activated.

Does this mean 3 Sticks would run just fine?

Yeah, I currently have 1 Corsair Vengeance LPX Red 8GB 2666MHz RAM stick.
It's about £50 for one stick and about £70 for 2, so was thinking of getting another 2 but wanted to make sure it was worth it, hence my initial query.
Since the board supports it I think I'll grab the 2, have 3 sticks in and if there are any issues I can just take one out til I can afford another :p.

Thanks everyone for the input.
