Cas 14 3200mhz Vs Cas 16 3600mhz

[Spils]

Thinking of picking up a 3600x in the sales and a 450 tomhawk max board. But which ram would be better suited. Without having to read a ton more which would you go with?

Was going to pick up one of the cas14 or cas16 8pack kits. to partner the above cpu and mobo?

??? the 14 will do 3600 most b die will even if you have to set it to cas 16 ... but prob/might do it at 14

Apparently according to Gibbo, they are both from the same bin, so with the 3200, you should have no problems getting 3600 C16

Though your CPU and Mobo is another matter?

I went for the 3200/14 for my b450 tomahawk max as it was about £30 cheaper than the 3600/16 at the time and it's been very solid, got it running at the minute at 3800/16 @1.42v it will also do 3600/14 but needed 1.46v.

Make sure you update the bios as pre abba infinity fabric maxed out at 1867 but now it's happy at 1900, have a r5 3600 non x btw.

My advice would be to get whatever is the cheaper.

Correct me if I am wrong but 3600 at cas 16 is slower than 3200 at cas 14?

2000x14/3200=8.75
2000x16/3600=8.88
2000x18/3866=9.31

The 3200 have the lowest latency while the 3600 have slightly more bandwidth, the supposedly higher binned 3866 kit have much higher latency at xmp not that you would run them at 3866 on ryzen but still.

What’s this 2000 number from? Getting my head around this.

I was under the impression it was simply:
14/3200=0.004375
16/3600=0.004444
18/3866=0.004656

Same overall outcome, different numbers. 14/3600 would be a super spicy number to get to.

The 2000 is just for the double date rate and it just simplifies the number your left with.

Yea it's essentially the same you would just x2 your numbers to account for the ddr 0.004375 x2 = 0.00875.

Still not sure why the higher binned ram has higher latency.
