Adding Ram to my current Build

[DiscoWarlock]

Hi guys, I currently have http://www.ncix.com/detail/kingston-hyperx-blu-black-series-44-78421.htm in my system, and I was looking to add another 8GB of RAM because I do alot of video editing and photoshop etc. However since they dont sell it anymore, or anywhere I can find it in Canada, I looked at another kind of similar option. So do I need to get the identical RAM for the other two slots or can I add whatever I want, I was looking to add https://www.amazon.ca/gp/product/B00J8E93G6/ref=s9_simh_gw_p147_d0_i1?pf_rd_m=A3DWYIK6Y9EEQB&pf_rd_s=desktop-1&pf_rd_r=CH2W3P2M73TZ8483Z15Y&pf_rd_t=36701&pf_rd_p=2055621862&pf_rd_i=desktop in the empty slots.
Any help is greatly appreciated,
Thanks

im no expert but looking at the specs of the two I think it would work fine, although you might have to mess with some setting due to different latency, I know people who run build like this and they are happy with it. Honestly though ram is pretty cheap these days so buying a new 16gb kit, and selling the old 8gb is a much safer option (and probably not much more expensive).

No guarantees when mixing sets of DRAM - even two identical sets, best would be to get a 2x8GB set, and sell the old, put it in another rig, or see if it will play with the new for an added bonus

Thanks for the answers, I'll be looking into a 16GB kit and maybe I'll get that bomus 8GB

When you try if any problems, give a shout, we can try voltage/timings adjustments

Hey guys, I just wanted to give an update. So I bought the Kingston HyperX Fury Black 16GB (2x8GB) 1600MHz set, and added it my build, and it works with no errors!(so far, *knocks on wood*). So I'm sitting with 24GB of RAM in total, the only issue I can see is that CPU-Z sees every slot except, slot 4, which should be an 8GB stick, however windows and the total memory page still sees the full 24GB.
Thanks again for the answers

Does CPU-Z show dual as a channels in the memory tab?

Hey guys
All I did was restart CPU-Z and boom everything was fine and dandy and it was showing everything correctly.
Thanks again for all the help
